Add nodeSelector and tolerations flags #47

Closed mgss-cc closed 2 weeks ago

mgss-cc commented 3 months ago

Hi,

It would be great if we are able to pass nodeSelector and tolerations as flags to the krelay command. Sometimes in multitenancy, we want pods to be deployed on certain nodes.

I plan to add a flag, say --custom, so that users are able to specify the path to a JSON or YAML file containing a partial pod object to customize the relay agent pod.

Let's take your use case as an example, you can do something like this:

$ cat custom-pod.yaml
spec:
  tolerations:
    - ...
  nodeSelector:
    k: v

$ kubectl relay --custom custom-pod.yaml ...

@mgss-cc Hi, with krelay 0.1.1, you could customize the krelay-server pod by the --patch/--patch-file flag. For instance:

$ kubectl relay --patch-file custom-pod.yaml ...
