Where do you give minions in a Kubernetes cluster a label?

[Stefan Jacobs]

Hi there, 

Can someone please tell me where you label a minion in a Kubernetes cluster? I've looked at quite a few examples and their "kubectl get minions" return <none> as labels.

Am I correct to assume you use this labels in conjunction with the nodeSelector variable in type PodSpec?

The use-case is to assign computational heavy dockers to appropriate machines. 

Thanks, 

Stefan

Hell Stefan.

I've read through the two links -- thank you!

Brendan, Joe: what is the status of supporting label updates for minions? Do we have a PR in progress for this? I did a quick search of our PRs and could not see something.

Cheers,

Satnam

We do support label updates for minions, it's a little complicated, but basically:

kubectl get minions foo -o json > foo.json

<edit foo.json>

kubectl update -f foo.json

Should do the trick.

We're working on adding a concrete "edit-label" command to kubectl also.

Thanks for the reply.

I'll test it tomorrow. I'm from South Africa so the time difference is a problem.

I asked more or less the same question on Stackoverflow here: http://stackoverflow.com/questions/28215472/how-do-you-update-a-node-minions-label-in-kubernetes

Brendan, all difference I can see with your solution is json instead of yaml.

Do I maybe miss something?
