[Guide](docs/index.md) encapsulates:
|
||||
- Test methodology that needs to be embraced.
|
||||
- Best practices that an OpenShift cluster, platform and applications running on top of it should take into account for best user experience, performance, resilience and reliability.

### How to Get Started
|
||||
Instructions on how to setup, configure and run Kraken can be found at [Installation](docs/installation.md).
|
||||
|
||||
You may consider utilizing the chaos recommendation tool prior to initiating the chaos runs to profile the application service(s) under test. This tool discovers a list of Krkn scenarios with a high probability of causing failures or disruptions to your application service(s). The tool can be accessed at [Chaos-Recommender](utils/chaos_recommender/README.md).
|
||||
|
||||
See the [getting started doc](docs/getting_started.md) on support on how to get started with your own custom scenario or editing current scenarios for your specific usage.
|
||||
|
||||
After installation, refer back to the below sections for supported scenarios and how to tweak the kraken config to load them on your cluster.
|
||||
|
||||
|
||||
#### Running Kraken with minimal configuration tweaks
|
||||
For cases where you want to run Kraken with minimal configuration changes, refer to [Kraken-hub](https://github.com/redhat-chaos/krkn-hub). One use case is CI integration where you do not want to carry around different configuration files for the scenarios.

### 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 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/redhat-chaos/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/redhat-chaos/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/redhat-chaos/krkn/blob/main/config/config.yaml) provided application routes are being monitored in the [cerberus config](https://github.com/redhat-chaos/krkn/blob/main/config/cerberus.yaml).

||||
- Leveraging [kube-burner](docs/alerts.md) alerting feature to fail the runs in case of critical alerts.

### Signaling
|
||||
In CI runs or any external job it is useful to stop Kraken once a certain test or state gets reached. We created a way to signal to kraken to pause the chaos or stop it completely using a signal posted to a port of your choice.

Monitoring the Kubernetes/OpenShift cluster to observe the impact of Kraken chaos scenarios on various components is key to find out the bottlenecks as it is important to make sure the cluster is healthy in terms if both recovery as well as performance during/after the failure has been injected. Instructions on enabling it can be found [here](docs/performance_dashboards.md).
|
||||
|
||||
|
||||
### Scraping and storing metrics long term
|
||||
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).
|
||||
|
||||
|
||||
### 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.

# I/O 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 disk pressure on a particular node of the Kubernetes/OpenShift cluster for a time span.
|
||||
The scenario allows to attach a node path to the pod as a `hostPath` volume.
|
||||
To enable this plugin add the pointer to the scenario input file `scenarios/arcaflow/io-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.
|
||||
- **target_pod_folder :** *string* the path in the pod where the volume is mounted
|
||||
- **target_pod_volume :** *object* the `hostPath` volume definition in the [Kubernetes/OpenShift](https://docs.openshift.com/container-platform/3.11/install_config/persistent_storage/using_hostpath.html) format, that will be attached to the pod as a volume
|
||||
- **io_write_bytes :** *string* writes N bytes for each hdd process. The size can be expressed as % of free space on the file system or in units of Bytes, KBytes, MBytes and GBytes using the suffix b, k, m or g
|
||||
- **io_block_size :** *string* size of each write in bytes. Size can be from 1 byte to 4m.
|
||||
|
||||
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
|
||||

[Krkn-hub](https://github.com/krkn-chaos/krkn-hub) is a wrapper that allows running Krkn chaos scenarios via podman or docker runtime with scenario parameters/configuration defined as environment variables.
|
||||
|
||||
Similarly, podman can be used to achieve the same:
|
||||
```
|
||||
$ podman pull quay.io/redhat-chaos/krkn
|
||||
$ podman run --name=kraken --net=host -v <path_to_kubeconfig>:/root/.kube/config:Z -v <path_to_kraken_config>:/root/kraken/config/config.yaml:Z -d quay.io/redhat-chaos/krkn:latest

## Scraping and storing metrics for the run
|
||||
|
||||
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. To help with this, Kraken supports capturing metrics for the duration of the scenarios defined in the config and indexes them into Elasticsearch. 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. Each run has a unique identifier ( uuid ) and all the metrics/documents in Elasticsearch will be associated with it. The uuid is generated automatically if not set in the config. This feature can be enabled in the [config](https://github.com/redhat-chaos/krkn/blob/main/config/config.yaml) by setting the following:
|
||||
|
||||
```
|
||||
performance_monitoring:
|
||||
kube_burner_binary_url: "https://github.com/cloud-bulldozer/kube-burner/releases/download/v0.9.1/kube-burner-0.9.1-Linux-x86_64.tar.gz"
|
||||
capture_metrics: True
|
||||
config_path: config/kube_burner.yaml # Define the Elasticsearch url and index name in this config.
|
||||
metrics_profile_path: config/metrics-aggregated.yaml
|
||||
prometheus_url: # The prometheus url/route is automatically obtained in case of OpenShift, please set it when the distribution is Kubernetes.
|
||||
prometheus_bearer_token: # The bearer token is automatically obtained in case of OpenShift, please set it when the distribution is Kubernetes. This is needed to authenticate with prometheus.
|
||||
uuid: # uuid for the run is generated by default if not set.
|
||||
```
|
||||
|
||||
### Metrics profile
|
||||
A couple of [metric profiles](https://github.com/redhat-chaos/krkn/tree/main/config), [metrics.yaml](https://github.com/redhat-chaos/krkn/blob/main/config/metrics.yaml), and [metrics-aggregated.yaml](https://github.com/redhat-chaos/krkn/blob/main/config/metrics-aggregated.yaml) are shipped by default and can be tweaked to add more metrics to capture during the run. The following are the API server metrics for example:
|
||||
|
||||
```
|
||||
metrics:
|
||||
# API server
|
||||
- query: histogram_quantile(0.99, sum(rate(apiserver_request_duration_seconds_bucket{apiserver="kube-apiserver", verb!~"WATCH", subresource!="log"}[2m])) by (verb,resource,subresource,instance,le)) > 0
|
||||
metricName: API99thLatency
|
||||
|
||||
- query: sum(irate(apiserver_request_total{apiserver="kube-apiserver",verb!="WATCH",subresource!="log"}[2m])) by (verb,instance,resource,code) > 0
|
||||
metricName: APIRequestRate
|
||||
|
||||
- query: sum(apiserver_current_inflight_requests{}) by (request_kind) > 0
|
||||
metricName: APIInflightRequests
|
||||
```
|
||||
|
||||
### Indexing
|
||||
Define the Elasticsearch and index to store the metrics/documents in the kube_burner config:
|
||||
|
||||
```
|
||||
global:
|
||||
writeToFile: true
|
||||
metricsDirectory: collected-metrics

||||
