While playing with the excellent lops I had the need to shutdown the cluster while not in use, this proved hard as every time I stopped the machines, something would turn it back on, turns out it was the AWS autoscaling groups.
To fix this I didn’t wanted to mess with the kops settings on the AWS side so I had to find the kops way to do this.
What I ended up doing was changing the instance groups to 0 using kops edit
For the nodes
kops edit ig nodes
and set maxSize and minSize to 0
for the master, I had to figure my master by doing
$ kops get ig Using cluster from kubectl context: staging.espresive.com NAME ROLE MACHINETYPE MIN MAX SUBNETS master-us-west-2a Master m3.medium 0 0 us-west-2a nodes Node t2.medium 0 0 us-west-2a
Then, with the name of my master
kops edit ig master-us-west-2a
and again set maxSize and minSize to 0
lastly, I had to update my cluster
kops update cluster --yes kops rolling-update cluster
Awesome, cluster is offline now! no need to go into AWS.
If you wanted to turn your cluster back on, rever the settings, changing your master to at least 1, and your nodes to your liking, I use 2.
I never had any problem using `kops delete cluster`
I didn’t wanted to delete the whole cluster, just stop it, I want to keep all the other resources except the instances (DNS entries, volumes, ELBs, VPCs etc)
