# Contributor Covenant Code of Conduct
|
||||
|
||||
## Our Pledge
|
||||
|
||||
We as members, contributors, and leaders pledge to make participation in our
|
||||
community a harassment-free experience for everyone, regardless of age, body
|
||||
size, visible or invisible disability, ethnicity, sex characteristics, gender
|
||||
identity and expression, level of experience, education, socio-economic status,
|
||||
nationality, personal appearance, race, religion, or sexual identity
|
||||
and orientation.
|
||||
|
||||
We pledge to act and interact in ways that contribute to an open, welcoming,
|
||||
diverse, inclusive, and healthy community.
|
||||
|
||||
## Our Standards
|
||||
|
||||
Examples of behavior that contributes to a positive environment for our
|
||||
community include:
|
||||
|
||||
* Demonstrating empathy and kindness toward other people
|
||||
* Being respectful of differing opinions, viewpoints, and experiences
|
||||
* Giving and gracefully accepting constructive feedback
|
||||
* Accepting responsibility and apologizing to those affected by our mistakes,
|
||||
and learning from the experience
|
||||
* Focusing on what is best not just for us as individuals, but for the
|
||||
overall community

||||
* Other conduct which could reasonably be considered inappropriate in a
|
||||
professional setting
|
||||
|
||||
## Enforcement Responsibilities
|
||||
|
||||
Community leaders are responsible for clarifying and enforcing our standards of
|
||||
acceptable behavior and will take appropriate and fair corrective action in
|
||||
response to any behavior that they deem inappropriate, threatening, offensive,
|
||||
or harmful.
|
||||
|
||||
Community leaders have the right and responsibility to remove, edit, or reject
|
||||
comments, commits, code, wiki edits, issues, and other contributions that are
|
||||
not aligned to this Code of Conduct, and will communicate reasons for moderation
|
||||
decisions when appropriate.
|
||||
|
||||
## Scope
|
||||
|
||||
This Code of Conduct applies within all community spaces, and also applies when
|
||||
an individual is officially representing the community in public spaces.
|
||||
Examples of representing our community include using an official e-mail address,
|
||||
posting via an official social media account, or acting as an appointed
|
||||
representative at an online or offline event.
|
||||
|
||||
## Enforcement
|
||||
|
||||
Instances of abusive, harassing, or otherwise unacceptable behavior may be
|
||||
reported to the community leaders responsible for enforcement.
|
||||
All complaints will be reviewed and investigated promptly and fairly.
|
||||
|
||||
All community leaders are obligated to respect the privacy and security of the
|
||||
reporter of any incident.
|
||||
|
||||
## Enforcement Guidelines
|
||||
|
||||
Community leaders will follow these Community Impact Guidelines in determining
|
||||
the consequences for any action they deem in violation of this Code of Conduct:
|
||||
|
||||
### 1. Correction
|
||||
|
||||
**Community Impact**: Use of inappropriate language or other behavior deemed
|
||||
unprofessional or unwelcome in the community.
|
||||
|
||||
**Consequence**: A private, written warning from community leaders, providing

### Kraken scenario pass/fail criteria and report
|
||||
It is important to make sure to check if the targeted component recovered from the chaos injection and also if the Kubernetes/OpenShift cluster is healthy as failures in one component can have an adverse impact on other components. Kraken does this by:
|
||||
- Having built in checks for pod and node based scenarios to ensure the expected number of replicas and nodes are up. It also supports running custom scripts with the checks.
|
||||
- Leveraging [Cerberus](https://github.com/openshift-scale/cerberus) to monitor the cluster under test and consuming the aggregated go/no-go signal to determine pass/fail post chaos. It is highly recommended to turn on the Cerberus health check feature available in Kraken. Instructions on installing and setting up Cerberus can be found [here](https://github.com/openshift-scale/cerberus#installation) or can be installed from Kraken using the [instructions](https://github.com/chaos-kubox/krkn#setting-up-infrastructure-dependencies). Once Cerberus is up and running, set cerberus_enabled to True and cerberus_url to the url where Cerberus publishes go/no-go signal in the Kraken config file. Cerberus can monitor [application routes](https://github.com/chaos-kubox/cerberus/blob/main/docs/config.md#watch-routes) during the chaos and fails the run if it encounters downtime as it is a potential downtime in a customers, or users environment as well. It is especially important during the control plane chaos scenarios including the API server, Etcd, Ingress etc. It can be enabled by setting `check_applicaton_routes: True` in the [Kraken config](https://github.com/chaos-kubox/krkn/blob/main/config/config.yaml) provided application routes are being monitored in the [cerberus config](https://github.com/chaos-kubox/krkn/blob/main/config/cerberus.yaml).

|
||||
Kraken supports capturing metrics for the duration of the scenarios defined in the config and indexes then into Elasticsearch to be able to store and evaluate the state of the runs long term. The indexed metrics can be visualized with the help of Grafana. It uses [Kube-burner](https://github.com/cloud-bulldozer/kube-burner) under the hood. The metrics to capture need to be defined in a metrics profile which Kraken consumes to query prometheus ( installed by default in OpenShift ) with the start and end timestamp of the run. Information on enabling and leveraging this feature can be found [here](docs/metrics.md).
|
||||
|
||||
|
||||
### Alerts
|
||||
In addition to checking the recovery and health of the cluster and components under test, Kraken takes in a profile with the Prometheus expressions to validate and alerts, exits with a non-zero return code depending on the severity set. This feature can be used to determine pass/fail or alert on abnormalities observed in the cluster based on the metrics. Information on enabling and leveraging this feature can be found [here](docs/alerts.md).
|
||||
### SLOs validation during and post chaos
|
||||
- In addition to checking the recovery and health of the cluster and components under test, Kraken takes in a profile with the Prometheus expressions to validate and alerts, exits with a non-zero return code depending on the severity set. This feature can be used to determine pass/fail or alert on abnormalities observed in the cluster based on the metrics.
|
||||
- Kraken also provides ability to check if any critical alerts are firing in the cluster post chaos and pass/fail's.
|

Information on enabling and leveraging this feature can be found [here](docs/SLOs_validation.md)
|
||||
|

|
||||
### OCM / ACM integration
|
||||
|
||||
Kraken supports injecting faults into [Open Cluster Management (OCM)](https://open-cluster-management.io/) and [Red Hat Advanced Cluster Management for Kubernetes (ACM)](https://www.redhat.com/en/technologies/management/advanced-cluster-management) managed clusters through [ManagedCluster Scenarios](docs/managedcluster_scenarios.md).

|
||||
- [Ability to visualize the metrics that are being captured by Kraken and stored in Elasticsearch](https://github.com/chaos-kubox/krkn/issues/124)
|
||||
- Ability to shape the ingress network similar to how Kraken supports [egress traffic shaping](https://github.com/chaos-kubox/krkn/blob/main/docs/network_chaos.md) today.
|
||||
- Continue to improve [Chaos Testing Guide](https://cloud-bulldozer.github.io/kraken/) in terms of adding best practices, test environment recommendations and scenarios to make sure the OpenShift platform, as well the applications running on top it, are resilient and performant under chaotic conditions.
|
||||
- Support for running Kraken on Kubernetes distribution - see https://github.com/chaos-kubox/krkn/issues/185, https://github.com/chaos-kubox/krkn/issues/186
|
||||
- Sweet logo for Kraken - see https://github.com/chaos-kubox/krkn/issues/195

### Kraken as a KubeApp
|
||||
|
||||
#### GENERAL NOTES:
|
||||
|
||||
- It is not generally recommended to run Kraken internal to the cluster as the pod which is running Kraken might get disrupted, the suggested use case to run kraken from inside k8s/OpenShift is to target **another** cluster (eg. to bypass network restrictions or to leverage cluster's computational resources)
|
||||
|
||||
- your kubeconfig might contain several cluster contexts and credentials so be sure, before creating the ConfigMap, to keep **only** the credentials related to the destination cluster. Please refer to the [Kubernetes documentation](https://kubernetes.io/docs/tasks/access-application-cluster/configure-access-multiple-clusters/) for more details
|
||||
- to add privileges to the service account you must be logged in the cluster with an highly privileged account (ideally kubeadmin)
|
||||
|
||||
|
||||
|
||||
To run containerized Kraken as a Kubernetes/OpenShift Deployment, follow these steps:
|
||||
1. Configure the [config.yaml](https://github.com/chaos-kubox/krkn/blob/main/config/config.yaml) file according to your requirements.
|
||||
|
||||
1. Configure the [config.yaml](https://github.com/redhat-chaos/krkn/blob/main/config/config.yaml) file according to your requirements.
|
||||
|
||||
**NOTE**: both the scenarios ConfigMaps are needed regardless you're running kraken in Kubernetes or OpenShift
|
||||
|
||||
2. Create a namespace under which you want to run the kraken pod using `kubectl create ns <namespace>`.
|
||||
3. Switch to `<namespace>` namespace:
|
||||
- In Kubernetes, use `kubectl config set-context --current --namespace=<namespace>`
|
||||
- In OpenShift, use `oc project <namespace>`
|
||||
4. Create a ConfigMap named kube-config using `kubectl create configmap kube-config --from-file=<path_to_kubeconfig>`
|
||||
5. Create a ConfigMap named kraken-config using `kubectl create configmap kraken-config --from-file=<path_to_kraken_config>`
|
||||
6. Create a ConfigMap named scenarios-config using `kubectl create configmap scenarios-config --from-file=<path_to_scenarios_folder>`
|
||||
7. Create a service account to run the kraken pod `kubectl create serviceaccount useroot`.
|
||||
8. In Openshift, add privileges to service account and execute `oc adm policy add-scc-to-user privileged -z useroot`.
|
||||
9. Create a Job using `kubectl apply -f kraken.yml` and monitor the status using `oc get jobs` and `oc get pods`.
|
||||
|
||||
NOTE: It is not recommended to run Kraken internal to the cluster as the pod which is running Kraken might get disrupted.
|
||||
- In Kubernetes, use `kubectl config set-context --current --namespace=<namespace>`
|
||||
- In OpenShift, use `oc project <namespace>`
|
||||
|
||||
4. Create a ConfigMap named kube-config using `kubectl create configmap kube-config --from-file=<path_to_kubeconfig>` *(eg. ~/.kube/config)*
|
||||
5. Create a ConfigMap named kraken-config using `kubectl create configmap kraken-config --from-file=<path_to_kraken>/config`
|
||||
6. Create a ConfigMap named scenarios-config using `kubectl create configmap scenarios-config --from-file=<path_to_kraken>/scenarios`
|
||||
7. Create a ConfigMap named scenarios-openshift-config using `kubectl create configmap scenarios-openshift-config --from-file=<path_to_kraken>/scenarios/openshift`
|
||||
8. Create a ConfigMap named scenarios-kube-config using `kubectl create configmap scenarios-kube-config --from-file=<path_to_kraken>/scenarios/kube`
|
||||
9. Create a service account to run the kraken pod `kubectl create serviceaccount useroot`.
|
||||
10. In Openshift, add privileges to service account and execute `oc adm policy add-scc-to-user privileged -z useroot`.
|
||||
11. Create a Job using `kubectl apply -f <path_to_kraken>/containers/kraken.yml` and monitor the status using `oc get jobs` and `oc get pods`.

## Arcaflow Scenarios
|
||||
Arcaflow is a workflow engine in development which provides the ability to execute workflow steps in sequence, in parallel, repeatedly, etc. The main difference to competitors such as Netflix Conductor is the ability to run ad-hoc workflows without an infrastructure setup required.
|
||||
|
||||
The engine uses containers to execute plugins and runs them either locally in Docker/Podman or remotely on a Kubernetes cluster. The workflow system is strongly typed and allows for generating JSON schema and OpenAPI documents for all data formats involved.
|
||||
|
||||
### Available Scenarios
|
||||
#### Hog scenarios:
|
||||
- [CPU Hog](arcaflow_scenarios/cpu_hog.md)
|
||||
- [Memory Hog](arcaflow_scenarios/memory_hog.md)
|
||||
|
||||
|
||||
### Prequisites
|
||||
Arcaflow supports three deployment technologies:
|
||||
- Docker
|
||||
- Podman
|
||||
- Kubernetes
|
||||
|
||||
#### Docker
|
||||
In order to run Arcaflow Scenarios with the Docker deployer, be sure that:
|
||||
- Docker is correctly installed in your Operating System (to find instructions on how to install docker please refer to [Docker Documentation](https://www.docker.com/))
|
||||
- The Docker daemon is running
|
||||
|
||||
#### Podman
|
||||
The podman deployer is built around the podman CLI and doesn't need necessarily to be run along with the podman daemon.
|
||||
To run Arcaflow Scenarios in your Operating system be sure that:
|
||||
- podman is correctly installed in your Operating System (to find instructions on how to install podman refer to [Podman Documentation](https://podman.io/))
|
||||
- the podman CLI is in your shell PATH
|
||||
|
||||
#### Kubernetes
|
||||
The kubernetes deployer integrates directly the Kubernetes API Client and needs only a valid kubeconfig file and a reachable Kubernetes/OpenShift Cluster.
|
||||
|
||||
### Usage
|
||||
|
||||
To enable arcaflow scenarios edit the kraken config file, go to the section `kraken -> chaos_scenarios` of the yaml structure
|
||||
and add a new element to the list named `arcaflow_scenarios` then add the desired scenario
|
||||
pointing to the `input.yaml` file.
|
||||
```
|
||||
kraken:
|
||||
...
|
||||
chaos_scenarios:
|
||||
- arcaflow_scenarios:
|
||||
- scenarios/arcaflow/cpu-hog/input.yaml
|
||||
```
|
||||
|
||||
#### input.yaml
|
||||
The implemented scenarios can be found in *scenarios/arcaflow/<scenario_name>* folder.
|
||||
The entrypoint of each scenario is the *input.yaml* file.
|
||||
In this file there are all the options to set up the scenario accordingly to the desired target
|
||||
### config.yaml
|
||||
The arcaflow config file. Here you can set the arcaflow deployer and the arcaflow log level.
|
||||
The supported deployers are:
|
||||
- Docker
|
||||
- Podman (podman daemon not needed, suggested option)
|
||||
- Kubernetes
|
||||
|
||||
The supported log levels are:
|
||||
- debug
|
||||
- info
|
||||
- warning
|
||||
- error
|
||||
### workflow.yaml
|
||||
This file contains the steps that will be executed to perform the scenario against the target.
|
||||
Each step is represented by a container that will be executed from the deployer and its options.
|
||||
Note that we provide the scenarios as a template, but they can be manipulated to define more complex workflows.
|
||||
To have more details regarding the arcaflow workflows architecture and syntax it is suggested to refer to the [Arcaflow Documentation](https://arcalot.io/arcaflow/).

# CPU Hog
|
||||
This scenario is based on the arcaflow [arcaflow-plugin-stressng](https://github.com/arcalot/arcaflow-plugin-stressng) plugin.
|
||||
The purpose of this scenario is to create cpu pressure on a particular node of the Kubernetes/OpenShift cluster for a time span.
|
||||
To enable this plugin add the pointer to the scenario input file `scenarios/arcaflow/cpu-hog/input.yaml` as described in the
|
||||
Usage section.
|
||||
This scenario takes a list of objects named `input_list` with the following properties:
|
||||
|
||||
- **kubeconfig :** *string* the kubeconfig needed by the deployer to deploy the sysbench plugin in the target cluster
|
||||
- **namespace :** *string* the namespace where the scenario container will be deployed
|
||||
**Note:** this parameter will be automatically filled by kraken if the `kubeconfig_path` property is correctly set
|
||||
- **node_selector :** *key-value map* the node label that will be used as `nodeSelector` by the pod to target a specific cluster node
|
||||
- **duration :** *string* stop stress test after N seconds. One can also specify the units of time in seconds, minutes, hours, days or years with the suffix s, m, h, d or y.
|
||||
- **cpu_count :** *int* the number of CPU cores to be used (0 means all)
|
||||
- **cpu_method :** *string* a fine-grained control of which cpu stressors to use (ackermann, cfloat etc. see [manpage](https://manpages.org/sysbench) for all the cpu_method options)
|
||||
- **cpu_load_percentage :** *int* the CPU load by percentage
|
||||
|
||||
To perform several load tests in the same run simultaneously (eg. stress two or more nodes in the same run) add another item
|
||||
to the `input_list` with the same properties (and eventually different values eg. different node_selectors
|
||||
to schedule the pod on different nodes). To reduce (or increase) the parallelism change the value `parallelism` in `workload.yaml` file

This section defines scenarios and specific data to the chaos run
|
||||
|
||||
## Distribution
|
||||
Either **openshift** or **kubernetes** depending on the type of cluster you want to run chaos on.
|
||||
The prometheus url/route and bearer token are automatically obtained in case of OpenShift, please set it when the distribution is Kubernetes.
|
||||
|
||||
## Exit on failure
|
||||
**exit_on_failure**: Exit when a post action check or cerberus run fails
|
||||
|
||||
## Publish kraken status
|
||||
**publish_kraken_status**: Can be accessed at http://0.0.0.0:8081 (or what signal_address and port you set in signal address section)
|
||||
**signal_state**: State you want kraken to start at; will wait for the RUN signal to start running a chaos iteration. When set to PAUSE before running the scenarios, refer to [signal.md](signal.md) for more details

|
||||
**chaos_scenarios**: List of different types of chaos scenarios you want to run with paths to their specific yaml file configurations
|
||||
|
||||
If a scenario has a post action check script, it will be run before and after each scenario to validate the component under test starts and ends at the same state
|
||||
|
||||
Currently the scenarios are run one after another (in sequence) and will exit if one of the scenarios fail, without moving onto the next one
|
||||

||||
Chaos scenario types:
|
||||
- container_scenarios

|
||||
Parameters to set for enabling of cerberus checks at the end of each executed scenario. The given url will pinged after the scenario and post action check have been completed for each scenario and iteration.
|
||||
**cerberus_enabled**: Enable it when cerberus is previously installed
|
||||
**cerberus_url**: When cerberus_enabled is set to True, provide the url where cerberus publishes go/no-go signal
|
||||
**check_applicaton_routes**: When enabled will look for application unavailability using the routes specified in the cerberus config and fails the run

||||
# Tunings
|
||||
**wait_duration**: Duration to wait between each chaos scenario
|
||||
**iterations**: Number of times to execute the scenarios
|
||||
**daemon_mode**: True or False; If true, iterations are set to infinity which means that the kraken will cause chaos forever and number of iterations is ignored

|
||||
|
||||
#### Workflow
|
||||
Let us start by understanding the workflow of kraken: the user will start by running kraken by pointing to a specific OpenShift cluster using kubeconfig to be able to talk to the platform on top of which the OpenShift cluster is hosted. This can be done by either the oc/kubectl API or the cloud API. Based on the configuration of kraken, it will inject specific chaos scenarios as shown below, talk to [Cerberus](https://github.com/chaos-kubox/cerberus) to get the go/no-go signal representing the overall health of the cluster ( optional - can be turned off ), scrapes metrics from in-cluster prometheus given a metrics profile with the promql queries and stores them long term in Elasticsearch configured ( optional - can be turned off ), evaluates the promql expressions specified in the alerts profile ( optional - can be turned off ) and aggregated everything to set the pass/fail i.e. exits 0 or 1. More about the metrics collection, cerberus and metrics evaluation can be found in the next section.

- Most of the scenarios have built in checks to verify if the targeted component recovered from the failure after the specified duration of time but there might be cases where other components might have an impact because of a certain failure and it’s extremely important to make sure that the system/application is healthy as a whole post chaos. This is exactly where [Cerberus](https://github.com/chaos-kubox/cerberus) comes to the rescue.

This is exactly where [Cerberus](https://github.com/redhat-chaos/cerberus) comes to the rescue.

If the monitoring tool, cerberus is enabled it will consume the signal and continue running chaos or not based on that signal.

|

- Apart from checking the recovery and cluster health status, it’s equally important to evaluate the performance metrics like latency, resource usage spikes, throughput, etcd health like disk fsync, leader elections etc. To help with this, Kraken has a way to evaluate promql expressions from the incluster prometheus and set the exit status to 0 or 1 based on the severity set for each of the query.

The following content covers the implementation details around how Startx is leveraging Kraken:
|
||||
|
||||
* Using kraken as part of a tekton pipeline
|
||||
|
||||
You can find on [artifacthub.io](https://artifacthub.io/packages/search?kind=7&ts_query_web=kraken) the
|
||||
[kraken-scenario](https://artifacthub.io/packages/tekton-task/startx-tekton-catalog/kraken-scenario) `tekton-task`
|
||||
which can be used to start a kraken chaos scenarios as part of a chaos pipeline.
|
||||
|
||||
To use this task, you must have :
|
||||
|
||||
- Openshift pipeline enabled (or tekton CRD loaded for Kubernetes clusters)
|
||||
- 1 Secret named `kraken-aws-creds` for scenarios using aws
|
||||
- 1 ConfigMap named `kraken-kubeconfig` with credentials to the targeted cluster
|
||||
- 1 ConfigMap named `kraken-config-example` with kraken configuration file (config.yaml)
|
||||
- 1 ConfigMap named `kraken-common-example` with all kraken related files
|
||||
- The `pipeline` SA with be autorized to run with priviveged SCC
|
||||
|
||||
You can create theses resources using the following sequence :
|
||||
|
||||
```bash
|
||||
oc project default
|
||||
oc adm policy add-scc-to-user privileged -z pipeline
|
||||
oc apply -f https://github.com/startxfr/tekton-catalog/raw/stable/task/kraken-scenario/0.1/samples/common.yaml
|
||||
```
|
||||
|
||||
Then you must change content of `kraken-aws-creds` secret, `kraken-kubeconfig` and `kraken-config-example` configMap
|
||||
to reflect your cluster configuration. Refer to the [kraken configuration](https://github.com/redhat-chaos/krkn/blob/main/config/config.yaml)
|
||||
and [configuration examples](https://github.com/startxfr/tekton-catalog/blob/stable/task/kraken-scenario/0.1/samples/)

- 1 configmap with kubeconfig of the targeted cluster
|
||||
- 1 job named kraken-test-xxx
|
||||
- 1 service to the kraken pods
|
||||
- 1 route to the kraken service

### Litmus Scenarios
|
||||
Kraken consumes [Litmus](https://github.com/litmuschaos/litmus) under the hood for some scenarios
|
||||
|
||||
Official Litmus documentation and specifics of Litmus resources can be found [here](https://docs.litmuschaos.io/docs/next/getstarted/)
|
||||
|
||||
|
||||
#### Litmus Chaos Custom Resources
|
||||
There are 3 custom resources that are created during each Litmus scenario. Below is a description of the resources:
|
||||
* ChaosEngine: A resource to link a Kubernetes application or Kubernetes node to a ChaosExperiment. ChaosEngine is watched by Litmus' Chaos-Operator which then invokes Chaos-Experiments.
|
||||
* ChaosExperiment: A resource to group the configuration parameters of a chaos experiment. ChaosExperiment CRs are created by the operator when experiments are invoked by ChaosEngine.
|
||||
* ChaosResult : A resource to hold the results of a chaos-experiment. The Chaos-exporter reads the results and exports the metrics into a configured Prometheus server.
|
||||
|
||||
### Understanding Litmus Scenarios
|
||||
|
||||
To run Litmus scenarios we need to apply 3 different resources/yaml files to our cluster.
|
||||
1. **Chaos experiments** contain the actual chaos details of a scenario.
|
||||
|
||||
i. This is installed automatically by Kraken (does not need to be specified in kraken scenario configuration).
|
||||
|
||||
2. **Service Account**: should be created to allow chaosengine to run experiments in your application namespace. Usually it sets just enough permissions to a specific namespace to be able to run the experiment properly.
|
||||
|
||||
i. This can be defined using either a link to a yaml file or a downloaded file in the scenarios' folder.
|
||||
|
||||
3. **Chaos Engine** connects the application instance to a Chaos Experiment. This is where you define the specifics of your scenario; i.e.: the node or pod name you want to cause chaos within.
|
||||
|
||||
i. This is a downloaded yaml file in the scenarios' folder. A full list of scenarios can be found [here](https://hub.litmuschaos.io/)
|
||||
|
||||
**NOTE**: By default, all chaos experiments will be installed based on the version you give in the config file.
|
||||
|
||||
Adding a new Litmus based scenario is as simple as adding references to 2 new yaml files (the Service Account and Chaos engine files for your scenario ) in the Kraken config.
|
||||
|
||||
|
||||

### ManagedCluster Scenarios
|
||||
|
||||
[ManagedCluster](https://open-cluster-management.io/concepts/managedcluster/) scenarios provide a way to integrate kraken with [Open Cluster Management (OCM)](https://open-cluster-management.io/) and [Red Hat Advanced Cluster Management for Kubernetes (ACM)](https://www.redhat.com/en/technologies/management/advanced-cluster-management).
|
||||
|
||||
ManagedCluster scenarios leverage [ManifestWorks](https://open-cluster-management.io/concepts/manifestwork/) to inject faults into the ManagedClusters.
|
||||
|
||||
The following ManagedCluster chaos scenarios are supported:
|
||||
|
||||
1. **managedcluster_start_scenario**: Scenario to start the ManagedCluster instance.
|
||||
2. **managedcluster_stop_scenario**: Scenario to stop the ManagedCluster instance.
|
||||
3. **managedcluster_stop_start_scenario**: Scenario to stop and then start the ManagedCluster instance.
|
||||
4. **start_klusterlet_scenario**: Scenario to start the klusterlet of the ManagedCluster instance.
|
||||
5. **stop_klusterlet_scenario**: Scenario to stop the klusterlet of the ManagedCluster instance.
|
||||
6. **stop_start_klusterlet_scenario**: Scenario to stop and start the klusterlet of the ManagedCluster instance.
|
||||
|
||||
ManagedCluster scenarios can be injected by placing the ManagedCluster scenarios config files under `managedcluster_scenarios` option in the Kraken config. Refer to [managedcluster_scenarios_example](https://github.com/redhat-chaos/krkn/blob/main/scenarios/kube/managedcluster_scenarios_example.yml) config file.

There are cases where the state of the cluster and metrics on the cluster during the chaos test run need to be stored long term to review after the cluster is terminated, for example CI and automation test runs.

The indexed metrics can be visualized with the help of Grafana.

It uses [Kube-burner](https://github.com/cloud-bulldozer/kube-burner) under the hood. The metrics to capture need to be defined in a metrics profile which Kraken consumes to query prometheus ( installed by default in OpenShift ) with the start and end timestamp of the run.

**NOTE**: Baremetal machines are fragile. Some node actions can occasionally corrupt the filesystem if it does not shut down properly, and sometimes the kubelet does not start properly.

#### Docker
|
||||
|
||||
The Docker provider can be used to run node scenarios against kind clusters.
|
||||
|

[kind](https://kind.sigs.k8s.io/) is a tool for running local Kubernetes clusters using Docker container "nodes".
|

|

**NOTE**: The `node_crash_scenario` and `stop_kubelet_scenario` scenario is supported independent of the cloud platform.
|

|
||||
Use 'generic' or do not add the 'cloud_type' key to your scenario if your cluster is not set up using one of the current supported cloud types.
|
||||
|
||||
Node scenarios can be injected by placing the node scenarios config files under node_scenarios option in the kraken config. Refer to [node_scenarios_example](https://github.com/chaos-kubox/krkn/blob/main/scenarios/node_scenarios_example.yml) config file.

## Pod network Scenarios
|
||||
|
||||
### Pod outage
|
||||
Scenario to block the traffic ( Ingress/Egress ) of a pod matching the labels for the specified duration of time to understand the behavior of the service/other services which depend on it during downtime. This helps with planning the requirements accordingly, be it improving the timeouts or tweaking the alerts etc.
|
||||
With the current network policies, it is not possible to explicitly block ports which are enabled by allowed network policy rule. This chaos scenario addresses this issue by using OVS flow rules to block ports related to the pod. It supports OpenShiftSDN and OVNKubernetes based networks.
|
||||
|
||||
##### Sample scenario config (using a plugin)
|
||||
```
|
||||
- id: pod_network_outage
|
||||
config:
|
||||
namespace: openshift-console # Required - Namespace of the pod to which filter need to be applied
|
||||
direction: # Optioinal - List of directions to apply filters
|
||||
- ingress # Blocks ingress traffic, Default both egress and ingress
|
||||
ingress_ports: # Optional - List of ports to block traffic on
|
||||
- 8443 # Blocks 8443, Default [], i.e. all ports.
|
||||
label_selector: 'component=ui' # Blocks access to openshift console
|
||||
```
|
||||
### Pod Network shaping
|
||||
Scenario to introduce network latency, packet loss, and bandwidth restriction in the Pod's network interface. The purpose of this scenario is to observe faults caused by random variations in the network.
|
||||
|
||||
##### Sample scenario config for egress traffic shaping (using plugin)
|
||||
```
|
||||
- id: pod_egress_shaping
|
||||
config:
|
||||
namespace: openshift-console # Required - Namespace of the pod to which filter need to be applied.
|
||||
label_selector: 'component=ui' # Applies traffic shaping to access openshift console.
|
||||
network_params:
|
||||
latency: 500ms # Add 500ms latency to egress traffic from the pod.
|
||||
```
|
||||
|
||||
##### Steps
|
||||
- Pick the pods to introduce the network anomaly either from label_selector or pod_name.
|
||||
- Identify the pod interface name on the node.
|
||||
- Set traffic shaping config on pod's interface using tc and netem.
|
||||
- Wait for the duration time.
|
||||
- Remove traffic shaping config on pod's interface.
|
||||
- Remove the job that spawned the pod.

### Pod Scenarios
|
||||
Kraken consumes [Powerfulseal](https://github.com/powerfulseal/powerfulseal) under the hood to run the pod scenarios.
|
||||
These scenarios are in a simple yaml format that you can manipulate to run your specific tests or use the pre-existing scenarios to see how it works.
|
||||
|
||||
Krkn recently replaced PowerfulSeal with its own internal pod scenarios using a plugin system. You can run pod scenarios by adding the following config to Krkn:
|
||||
|
||||
```yaml
|
||||
kraken:
|
||||
chaos_scenarios:
|
||||
- plugin_scenarios:
|
||||
- path/to/scenario.yaml
|
||||
```
|
||||
|
||||
You can then create the scenario file with the following contents:
|
||||
|
||||
```yaml
|
||||
# yaml-language-server: $schema=../plugin.schema.json
|
||||
- id: kill-pods
|
||||
config:
|
||||
namespace_pattern: ^kube-system$
|
||||
label_selector: k8s-app=kube-scheduler
|
||||
- id: wait-for-pods
|
||||
config:
|
||||
namespace_pattern: ^kube-system$
|
||||
label_selector: k8s-app=kube-scheduler
|
||||
count: 3
|
||||
```
|
||||
|
||||
Please adjust the schema reference to point to the [schema file](../scenarios/plugin.schema.json). This file will give you code completion and documentation for the available options in your IDE.
