flag to deploy to specific namespace

[surajssd]

Right now kedge deploy, deploys to the current namespace that is selected. But it would be awesome to have a flag that we can use to deploy to specific namespace.

Something like following:

kedge deploy -n foo -f web.yaml
kedge deploy --namespace foo -f web.yaml

ping @kedgeproject/maintainers, are we good with the UX on this before we proceed?

[cdrage]

Yup. --namespace and -n makes sense.

[concaf]

Do we want to scope specifying namespace using -n only to kedge deploy/apply or do want it for generate too? ObjectMeta has Namespace string as a field, so we could substitute it there for the generated artifacts.

Btw, namespace can also be specified in the kedge spec for the application alternatively since it's a part of ObjectMeta.

[surajssd]

@containscafeine do we have ObjectMeta? I don't think we have?

[concaf]

@surajssd totally missed that :) Yeah, so namespace cannot go in the spec the way it is right now.
WDYT about extending this to kedge generate as well?

[surajssd]

I don't have problem in doing it in generate, but it's just that we will have to handle it when we are creating the ObjectMeta!

[kadel]

I don't think namespace should be there for generate.
I don't like when a namespace is hardcoded in artifacts.

If you are deploying such artifacts you have to be extra careful to deploy it to the right namespace.

[cdrage]

I'd agree with @kadel that --namespace should be within create / delete rather than generate (makes no sense there)
