Perform rolling update about cabin

Is there a lot of parameters we can change ? Being able to edit the yaml can be simple, but not really nice/practical on a mobile phone :/

[sebgoa]

let's just do the image for now, which could be for example:

mysql:5.5

changed to

mysql:5.6

So I can just add an editable field for the image in the RC/Deployment show view and perform a Patch request ? :)

[sebgoa]

yes....

in kubectl it is kubectl apply.

this is only for Deployments.

But the image depends on the container right ?
So for each Container in a Deployment we should be able de edit the image ?

[sebgoa]

correct, a deployment starts pod, and there could be multiple container in a pod.

so possible multiple images to change

I've started implementing the UI (Three dots in RC view, then enter the new image)
But I don't understand how a rolling update works, seems like we have to implement it by hand, but can't manage to make rolling update works on my cluster to see what api calls are made.

Need clarifications...

[sebgoa]

so here is more details with the kubectl edit command.
Basically send a patch request changing the Pod template defined in a deployment.

We only do this for deployments, not for RC.
We only allow to change the image (for now...)

$ kubectl get deployments

ok done ✅ now there is a "more" button in the upper right in the deployment view. Allowing you to "change image"

[sebgoa]

seems to work +1
