2.13.0

Release Notes (2.13.0)

Core Component Updates -

• Enhance network experiments to derive IPs of the pods for Kubernetes service if the target pod has a service mesh sidecar. This will enable us to run all network chaos experiments with service mesh enabled effectively. litmuschaos/litmus-go#558

• Adds Chaos SDK Templates for non-Kubernetes experiments (that is aws, gcp, vmware, azure) this will help us to speed up the experiment development process with a proper template for non-k8s services. To know more refer to the developer docs. litmuschaos/litmus-go#560

• Fixes the stress-chaos experiments to run chaos (helper pod) with minimum capabilities. This will allow running the stress experiments in a restricted environment (like Openshift) with lesser capabilities as mentioned in SCC docs. litmuschaos/litmus-go#557

• Enhance the HTTP status code experiment to have the ability to modify the response body. Also, it adds support to provide the content type and encoding for the body in modify body and status code experiment. litmuschaos/litmus-go#556

• Adds the ability to provide custom Service Account value for helper pod using CHAOS_SERVICE_ACCOUNT Env. It is optional, if not provided the helper pod will run with the same service account as the experiment pod. litmuschaos/chaos-runner#178

• Enhance chaos-operator to enable the leader-elect this ensures with multiple replicas a leader is elected and is the only one actively reconciling the set.litmuschaos/chaos-operator#417

• Refactor chaos operator code to convert the History field in ChaosResult spec as a Go pointer. litmuschaos/chaos-operator#416

• Enhance the chaos (helper pod) status check when waiting for completion with proper error handling. litmuschaos/litmus-go#552

• Adds document content for a better understanding of new HTTP chaos experiments and tunables. #3755

2.11.0

Release Notes (2.11.0)

Core Component Updates -

• Introduce different new HTTP chaos experiments for Kubernetes targets, this will allow users to introduce the following faults:

  • pod-http-status-code (modifies the status code of the response)
  • pod-http-modify-body (modifies the body of the response)
  • pod-http-modify-header (modify headers of incoming requests or the response from the service targetted)
  • pod-http-reset-peer (stops outgoing http requests by resetting the TCP connection)

  To know more checkout the experiment-docs.

• Upgrade the operator SDK version to 1.14.0 for chaos operator and code refator for other litmus components to achieve compatibility.

• Adds support for non-default vpc for the AWS ELB az-down experiment. As earlier the experiment only targets the ELB(s) that are associated with default vpc, so this will also allow the user to target the ELB(s) that are not associated with default vpc.

• Enhance cmd probe spec to support different configuration for probe pod and containers like imagePullPolicy, cmd, args and so on. This will allow the user to run the cmd probe in more controlled way when used in source mode.

• Fixes the error handling for application status check with litmus annotation for pod-level experiments.

• Adds litmusctl docker image which will allow the users to install the agents (delegates) from a pod/container.

ChaosCenter Updates -

• Updates terminologies for different entities -

  • Agents --> Chaos Delegates
  • Workflows --> Chaos Scenarios
  • Charts --> Chaos Experiments

• Reduces the permissions in namespaced mode for execution plane components

• Fixes an issue in SyncHub API when there is an error in communication between graphql-server and MongoDB and all hubs were getting deleted while trying to reclone current chaoshub.

NOTE: - Along with above terminologies updates, we will also be updating directory structure of ChaosHub for better readability and scalability of experiments and scenarios. With upcoming release, the charts will be renamed to experiments directory and workflows will be renamed to scenarios. Same changes have been already done in 2.11.0 version of ChaosHub.

Full Changelog: 2.9.0...2.10.0

2.9.0

Release Notes (2.9.0)

Core Component Updates -

• Adds GCP Instance Stop and Disk Fill Experiments by the label that supports multiple target selection using common labels.

• Refactor the GCP disk loss experiment to remove the device name input and auto-derive it within the experiment.

• Enhance EC2 Terminate experiment checks when the managed nodegroup env is enabled to validate the node recovery through AWS APIs instead of Kubernetes APIs.

• Introduces GCP IAM integration through workload identity for keyless authentication in GKE clusters.

• Fixes Litmus SDK and introduces the default app health check feature in the SDK template.

• Fixes error handling for an invalid appinfo input. The experiments are now supposed to fail in the pre chaos validation and won’t go to the chaos injection stage.

• Fixes chaos injection issues on OpenShift due to the helper pod failure caused due to the same IP it was assigned as the experiment pod, it occurs due to the same annotation shared by helper and experiment pods. Now, this can be tuned via an env called SET_HELPER_DATA if we don’t want to use the experiment data inside helper pods we can enable it.

• Adds chaos charts for process kill experiment which is in beta version and runs with the help of m-agent.

• Fixes the default value of the chaos tunable in the stress chaos experiment to support the default execution of the experiment.

• Cleanup the stale workflows from chaos charts and retain the active workflows only.

• Adds document fixes for stress chaos experiment and introduces docs for GCP IAM integration.

• Adds m-agent e2e pipeline that includes tests for process kill experiment.

ChaosCenter Updates -

• Weight and experiments mapping logic has been updated for handling cases where one workflow contains more than one instance of the same experiment. Now chaosengine name will be used for mapping experiment to the corresponding weight.

• Refactored GQL server APIs for better documentation & following a standard schema.

• Updated API docs according to new changes and added missing APIs.

• Added support for using a custom image registry inside the experiment when using a custom image registry.

• Updated the namespaced scope manifest to reduce the complexity of installation instructions.

• Fixed permission issue for event-tracker in namespaced mode.

• Fixed image version in revert-chaos step for using versioned tag instead of latest.

• Fixed error logging in subscriber for handling error when there are fewer permissions available due to old installation.

• Fixed error logging in Control-plane upgrade agent when new and current versions are the same by providing a warning instead of the error.

NOTE: As all the APIs on graphql-server have been updated for following a standard schema, Litmusctl has also been updated for supporting the same. So, ChaosCenter v2.9.0 will be compatible with Litmusctl v0.10.0. Please make sure to upgrade the litmusctl before using with ChaosCenter v2.9.0.

• Fixes the permission issue faced by container user (of different litmus components) to access its directory in an Openshift cluster as the openshift cluster runs the container with an arbitrary uid in the root group.

• Enhance the stress chaos experiments to gracefully terminate the stress process in case it is not completed and remove on its own.

• Enhance the node drain experiment to skip the uncordon step post chaos if the target node is not available. It occurs if we enable the autoscaling for the node pool on the cloud provider.

• Updates the experiment contributing docs with the usage of litmus SDK and also adds the chaos-chart details in the repo readme.

• Adds an overview section in litmus-python with the detailed steps for preparing and using the experiment and workflows in python.

• Adds new e2e-pipeline for testing the vm-ware experiments from hub. It supports both nightly and manual builds.

• Enhance the e2e-dashboard to show the logs of the tests running in the e2e pipeline.

• Enhance GitHub Chaos Actions to support AWS EKS clusters, with this now we can integrate any external EKS cluster with chaos action to run the experiments.

Chaos Center Updates

• Upgrading argo workflow and event tracker API versions to support chaos center on Kubernetes 1.22.0+

• Addition of a new event tracker policy operator (known as Change) to track values of any field in the Kubernetes resource and removed the dependency of event tracker from last applied configuration annnotation

• Addition of new permissions to docker images of ChaosCenter server to OpenShift friendly

• Migration of APIs from graphql-server to auth-server and introduction of gRPC for the internal communication

• Addition of "--skipSSL" flag in litmusctl to disable SSL for the communication between control-plane and execution plan

• IPV6 support for control plane

• Addition of new E2E tests for observability.

Notes

• The CRDs for ChaosCenter will be versioned now . So, CRDs for ChaosCenter v2.x.x will be available in 2.x.x branch.
• The Project DB migration has been done in this release along with some enhancements (like addition of new flag --skipSSL), so any version of litmusctl below v0.7.0 won't be compatible with ChaosCenter 2.4.0 or above.
