+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
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a

+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.

+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
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.

 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).

+## 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

-### 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.

+## 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.
