Unable to do openshiftTag() in pipeline about jenkins-plugin HOT 1 CLOSED

I believe you are ultimately trying an option for tagging available with the CLI which is not available with the openshift-pipeline plugin.

You only specified a token my-token-for-my.localhost.openshift.com for the destination name space openshift-project

You did not specify a token for the source namespace external.registry.host.com, which by the way does not sound like a valid openshift namespace name, but an external docker registry.

If so, we are failing trying to access the project/namespace external.registry.host.com from the openshift master. And if by some add stretch such a project does exist, since you don't specify the source token for any non-default source namespace the plugin will use the service account token for the project hosting jenkins, and that token does not have access.

The plugin does not have the feature currently to try and access the source as an external docker registry.

If you don't think this analysis hits the mark, please re-open and clarify.

To ultimately work around this, I suggest you use our new plugin. See https://github.com/openshift/jenkins-client-plugin. It provides pipeline DSL that allows for direct invocation of the oc command in the openshift jenkins image. You can then leverage the oc commands capability to specify and external docker registry as a source for the tag command.
