Description
Allow registry, registry username, and password to be empty strings. These values are passed as kernel command line args for OSIE's boot up and then used by Tink worker when it pulls and runs containers. With this change to Tink worker, allowing the empty string here provides Tink worker the ability to specify any fully qualified container image in a template. e.g.
docker.io/alpine
,quay.io/tinkerbell-actions/cexec
,public.ecr.aws/l0g8r8j6/tinkerbell/pbnj
, etcThis change is backward compatible and shouldn't negatively affect using the Cacher backend.
