A couple of days ago I am looking for a tool to manage different Kubernetes Clusters in my only laptop. But after a while, I realized that
kubectl actually support multi-clusters by itself (link).
Then I opened my
.kube/config file and saw
clusters: - cluster: name: ClusterA - cluster: name: ClusterB users: - user: name: UserA - user: name: UserB contexts: - context: cluster: ClusterA user: UserA name: ContextA - context: cluster: ClusterB user: UserB name: ContextB current-context: ContextA
Seems that we could directly use
argo command to submit Argo workflow to different k8s clusters:
argo submit job_a.xml --context ContextA argo submit job_b.xml --context ContextB
Since the context names are automatically generated by
gcloud container clusters get-credentials <gke_cluster_name>, what should I do if I want to make the name more intuitive?
The answer is here. We can just use:
kubectl config rename-context <old_context_name> <new_context_name>
