Typeo Slide 7.13.a Deployment Rollbacks

btanoue

Hi,
I tried to use the record function and thought I was fat fingering it. So I copied and pasted it from the slide.
kubectl create deploy ghost --image=ghost --record

I get this output.

Use "kubectl options" for a list of global command-line options (applies to all commands).

unknown flag: --record

The Deployment doesn't seem to like the record switch.
Is there another I can try?

Hello,
Yes, good catch. The --record option now only works with changes to the deployment, no longer the creation. When the built in generator for run was removed the --record option no longer works.

You could use: kubectl run --generator=deployment/apps.v1beta1 oldstyle --image=nginx --record
You will get a deprecation warning, but it will work.

Then view the recorded info with: kubectl rollout history deployment oldstyle

I'll make sure to update the content.

Is there a new way that isn't deprecated that I should be learning? I like the idea of annotations.
Or
kubectl create deployment ghost image=ghost
To create it. Then how do I add the recording after?

serewicz

The manner of what is created and deprecated is not consistent, and the removal of the run generator wasn't well thought out, IMHO. Only the run --generator manner has the ability to add the comment at the same time as far as I know.

You would otherwise have to run a second command to annotate or record afterward.

Hi,

can you write the two commands. I’d like to try that first. I’m ok with creating and then adding the annotation. I want to see how it works.

Thanks

Hello,
I wrote the command a few posts back:

You could use: kubectl run --generator=deployment/apps.v1beta1 oldstyle --image=nginx --record
You will get a deprecation warning, but it will work.

If you create a deployment, such as kubectl create deployment newstyle --image=nginx it no longer accepts the record option. After it has been created you can use set,edit, apply etc and use the --record option to document the change.

Thanks for the clarification.
