Drone CI secrets not populating

Question

I am trying to push a docker image into a private registry in Drone 0.8.5 and it works when I hardcode username and password into the pipeline however I have tried adding both the registry details in the registry tab and as secrets.

Registry Pipeline

docker-registry-push:
  image: plugins/docker
  repo: registry.domain.com:5000/app
  registry: registry.domain.com:5000
  insecure: true
  pull: true

Fails with no basic auth credentials

Finally I've tried variable substitution. (with $REGISTRY_USERNAME and $$REGISTRY_USERNAME variables. All result in a error msg="Error authenticating: exit status 1"

docker-registry-push:
  image: plugins/docker
  repo: registry.domain.com:5000/app
  registry: registry.domain.com:5000
  secrets:
    - source: registry_username
      target: username
    - source: registry_password
      target: password
  insecure: true
  pull: true

another attempt

docker-registry-push:
  image: plugins/docker
  repo: registry.domain.com:5000/app
  registry: registry.domain.com:5000
  username: ${REGISTRY_USERNAME}  
  password: ${REGISTRY_PASSWORD}
  secrets: [ registry_username, registry_password ]
  insecure: true
  pull: true

It is really frustrating. I need to add secrets for Rancher accesskey secretkey also after this via the correct method.

I have read other topics and the drone docs and am still stumped.

Thanks in advance.

The secrets need to be injected into the docker container via the environment with the names docker_username and and docker_password.

Your .drone.yml file should look something like this:

pipeline:
  docker:
    image: plugins/docker
    repo: username/app
    registry: registry.domain.com:5000
    insecure: true
    pull: true
    secrets:
      - source: registry_username
        target: docker_username
      - source: registry_password
        target: docker_password

See the drone plugin docs for more configuration options.
