Steps for Helm chart Cleanup

To uninstall a chart

helm uninstall <release-name> -n <namespace>

To list all the helm chart deployments

helm list -A

Cleanup steps that needs to be done for a fresh deployment

• Uninstall all the chart deployments.
• Cleanup the data at NFS mount and trustagent data mount on each nodes (/etc/trustagent, /var/log/trustagent)
• Remove all objects(secrets, rbac, clusterrole, service account) related namespace related to deployment kubectl delete ns <namespace>.
• For charts Trusted-Workload-Placement and Trusted-Workload-Placement-Cloud-Service-Provider, ISecl-Scheduler should be disconnected from K8s base scheduler. This can be done by configuring in manifest of kube-scheduler as mentioned below, by commenting the --config option

  containers:
  - command:
    - kube-scheduler
    - --authentication-kubeconfig=/etc/kubernetes/scheduler.conf
    - --authorization-kubeconfig=/etc/kubernetes/scheduler.conf
    - --bind-address=127.0.0.1
    - --kubeconfig=/etc/kubernetes/scheduler.conf
    - --leader-elect=true
    #- --config=/opt/isecl-k8s-extensions/kube-scheduler-configuration.yml
  

• Restart Kubelet which restart all the k8s services including kube base scheduler

      systemctl restart kubelet
  

Note:

Before redeploying any of the chart please check the pv and pvc of corresponding deployments are removed. Suppose if you want to redeploy aas, make sure that aas-logs-pv, aas-logs-pvc, aas-config-pv, aas-config-pvc, aas-db-pv, aas-db-pvc, aas-base-pvc are removed successfully.
Command: `kubectl get pvc -n <namespace>` && `kubectl get pv -n <namespace>`
