• You can use the kubectl command to access both the cluster1 and cluster2 clusters with the --context flag, for example kubectl get pods --context cluster1. Use the following command to list your contexts:

  {{< text bash >}} $ kubectl config get-contexts CURRENT NAME CLUSTER AUTHINFO NAMESPACE

  •     cluster1   cluster1   user@foo.com   default
        cluster2   cluster2   user@foo.com   default
    

  {{< /text >}}

• Store the context names of your clusters in environment variables:

  {{< text bash >}} export CTX_CLUSTER1=(kubectl config view -o jsonpath='{.contexts[0].name}') export CTX_CLUSTER2=(kubectl config view -o jsonpath='{.contexts[1].name}') echo "CTX_CLUSTER1 ={CTX_CLUSTER1}, CTX_CLUSTER2 = ${CTX_CLUSTER2}" CTX_CLUSTER1 = cluster1, CTX_CLUSTER2 = cluster2 {{< /text >}}

  {{< tip >}} If you have more than two clusters in the context list and you want to configure your mesh using clusters other than the first two, you will need to manually set the environment variables to the appropriate context names. {{< /tip >}}
