@simo5 Mind adding single quotes around the new oc command?

Can you also use the moved function where these commands are specifed, similarly to this. This way when you invoke oc policy these deprecated commands will be appropriately marked as well.

@simo5 Mind adding single quotes around the new oc command?

@juanvallejo why? I don't recall seeing oc in quotes anywhere

One more thing, use lowercase, since this gets appended to the following sentence Command xyz is deprecated, <here goes your string>

@soltysh

why? I don't recall seeing oc in quotes anywhere

Saw this being the pattern in a few places:

https://github.com/openshift/origin/blob/master/pkg/oc/admin/admin.go#L134

https://github.com/openshift/origin/blob/master/pkg/oc/admin/node/node.go#L98

https://github.com/openshift/origin/blob/master/pkg/oc/cli/cli.go#L281

I looked into cobra (see here) and that's why it does make sense to be it lowercase.

Are there any backwards compatible implications in changing this, or this is just cosmetics for stability of tests?

No real backwards incompatibility, just tests were making assumptions that are not true "in real life" about which rolebindings were going to be used by the test.

Because the commands was picking the first rolebinding it would find you can never be certain of what rolebinding was used. By changing the command to always pick a new rolebinding we may cause some incorrect expectations to "fail early", so that people will end up fixing latent bugs that were always there.

As you can see by tests being all green, luckily this faulty assumption seem to not have been relied upon anywhere in our code base except for the tests testing the feature itself.

Push people to use native RBAC commands where reasonable equivalents exist, or where the replacement command will lead to better practices. Signed-off-by: Simo Sorce <simo@redhat.com>

Instead of deprecating add/remove-role commands, change them to behave better. On add: do not add to a random rolebinding, always create a new rolebinding if none was specified explicitly. On Remove: if a rolebinding name is specified remove only from it. Signed-off-by: Simo Sorce <simo@redhat.com>

This is missing the role check like getUserSpecifiedBinding:

// Check that we update the rolebinding for the intended role. if roleBinding.RoleRef.Name != o.RoleName || roleBinding.RoleRef.Namespace != o.RoleNamespace { return nil, false, fmt.Errorf("rolebinding %s found for role %s, not %s", roleBinding.Name, roleBinding.RoleRef.Name, o.RoleName) }

This should error instead of doing the wrong thing:
