To upgrade Litmus ChaosCenter from 2.1.0 to 2.2.0, you can follow these steps:
Disconnect the agent components To disconnect agents, you can do it from the chaoscenter by clicking the
disconnectbutton. With this, the subscriber deployment and agent-config will be removed from the agent cluster.
Upgrade the control plane (ChaosCenter) To upgrade ChaosCenter, you can re-apply the manifest using the kubectl.
kubectl apply -f https://raw.githubusercontent.com/litmuschaos/litmus/master/mkdocs/docs/2.2.0/litmus-2.2.0.yaml
Reinstall the agent components using litmusctl
Note: While reinstallation, make sure to use the same agent name
To reinstall the ChaosAgents, use Litmusctl
Note: This step is not required for upgrading 2.1.0 to 2.2.0
To upgrade the DB schema, make sure to delete the PV before re-installing ChaosCenter.
To upgrade your ChaosAgent, you can follow these steps:
- If an upgrade is available, you will get an option to upgrade your agent in the ChaosCenter. Upon clicking on the upgrade option, a modal will pop up providing you the litmusctl command which you can execute and your ChaosAgent will be upgraded.
Alternatively you can run the following command using litmusctl in the cluster containing the agent by providing
litmusctl upgrade agent --cluster-id="<CLUSTER_ID>" --project-id="<PROJECT_ID>"
Note: v0.5.0 of litmusctl is required.
