The
additional_private_registries
parameter (from this PR: #345) is broken when when this resource type is built using the alpine linux Dockerfile, but it works as intended using the ubuntu Dockerfile.The reason for this is because alpine's
base64
doesn't accept--decode
. Both ubuntu and alpine understand-d
, so let's change it to pass that instead.Crucially, the docker-image resource type bundled with concourse is built from the alpine Dockerfile, so
additional_private_registries
will not work until this is merged, released, and bundled into a new version of concourse.
