Updating the Kubeturbo role through YAML

Update the role if you deployed Kubeturbo with a specific role and now want to use a different role. For example, you may want to change the role from turbo-cluster-reader to turbo-cluster-admin to execute actions in Turbonomic.

1. Delete the Cluster Role Binding (CRB) that starts with the naming convention turbo-all-binding-kubeturbo.

   For example, to delete turbo-all-binding-kubeturbo-turbo, run the following command:

   kubectl delete clusterrolebinding turbo-all-binding-kubeturbo-turbo

2. Create a new role for Kubeturbo.

   • To use the turbo-cluster-admin role, run the following command.

     kubectl apply -f https://raw.githubusercontent.com/turbonomic/kubeturbo-deploy/master/deploy/kubeturbo_yamls/turbo-admin.yaml

   • To use the turbo-cluster-reader role, run the following command.

     kubectl apply -f https://raw.githubusercontent.com/turbonomic/kubeturbo-deploy/master/deploy/kubeturbo_yamls/turbo-reader.yaml

   Note:

   For the default cluster-admin role, there is no YAML resource to apply. Kubeturbo will automatically switch to this role after you apply the corresponding CRB (see the next step).

3. Create a new CRB for Kubeturbo.

   • To use the turbo-cluster-admin CRB, run the following command.

     kubectl apply -f https://raw.githubusercontent.com/turbonomic/kubeturbo-deploy/master/deploy/kubeturbo_yamls/step3_turbo_serviceAccountRoleBinding_turbo-cluster-admin_sample.yaml

   • To use the turbo-cluster-reader role, run the following command.

     kubectl apply -f https://raw.githubusercontent.com/turbonomic/kubeturbo-deploy/master/deploy/kubeturbo_yamls/step3_turbo_serviceAccountRoleBinding_turbo-cluster-reader_sample.yaml

   • To use the cluster-admin CRB, run the following command.

     kubectl apply -f https://raw.githubusercontent.com/turbonomic/kubeturbo-deploy/master/deploy/kubeturbo_yamls/step3_turbo_serviceAccountRoleBinding_admin_sample.yaml

4. Delete the Kubeturbo pod.

   1. Get a list of pods.

      kubectl get pods -n turbo

   2. Find the Kubeturbo pod. The following example shows a Kubeturbo pod named kubeturbo-asdf1234asd3.

      NAME                    READY  STATUS   RESTARTS  AGE
      kubeturbo-asdf1234asd3  1/1    Running  0         37m

   3. Delete the Kubeturbo pod.

      kubectl delete pod kubeturbo-{kubeturbo_pod_ID} -n turbo

      For example:

      kubectl delete pod kubeturbo-asdf1234asd3 -n turbo
