I am playing with Kubernetes on google compute engines, and I would like to do something that will stop multiple instances at the same time.
I reason of this is, Kubernetes will create a cluster which contains partial common names, for example,
kubernetes-minion-group-1
kubernetes-minion-group-2
......Kubernetes has the option to delete all the instances, but I couldn't found the option to shutdown them. I don't want to delete all the instance and recreate the next time.
I understand that the following command will delete one instance,
gcloud compute instances stop kubernetes-minion-group-1but how to stop all of them at the same time in one line or maybe in a bash script? like,
gcloud compute instances stop (instances contains 'kubernetes')Thank you in advance.
I'm not sure if there's a cleaner way, but something based on the below using instances list might work:
gcloud compute instances list --filter 'name:kubernetes' --format="csvno-heading"
...which you'd have to parse/grep to get the list. I told it to give a CSV of just the name attributes that match, with no title row (you might be able to play with different topic formats to get one that works exactly like a spaced list. Then:
gcloud computes instances stop [list of names]
It seems 'stop' won't take a filter or wildcard. :/
