As a user of crane, I may have many contexts stored in my $KUBECONFIG and those contexts may not necessarily be constrained to a particular namespace already. I want to be able to export resources from a specific namespace from one of my clusters (that may not be my current context).

Currently, the crane tool says this about context and namespace:

      --context string      The kube context, if empty it will use the current context. If --namespace is set it will take precedence
  -n, --namespace string    The kube namespace to export.

An example scenario would be one like the kubeconfig below:

apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: DATA+OMITTED
    server: https://127.0.0.1:38103
  name: kind-dest
- cluster:
    certificate-authority-data: DATA+OMITTED
    server: https://127.0.0.1:36921
  name: kind-src
contexts:
- context:
    cluster: kind-dest
    user: kind-dest
  name: kind-dest
- context:
    cluster: kind-src
    user: kind-src
  name: kind-src
current-context: kind-dest
kind: Config
preferences: {}
users:
- name: kind-dest
  user:
    client-certificate-data: REDACTED
    client-key-data: REDACTED
- name: kind-src
  user:
    client-certificate-data: REDACTED
    client-key-data: REDACTED

And I want to export resources from the 'guestbook' namespace of the 'kind-src' cluster. I should be able to do so with:

        /crane export \
          --namespace=guestbook \
          --export-dir=${EXPORT_DIR} \
          --context=kind-src
