Docker Plugin Push no basic auth credentials

Drone Support
1

Hi, I’m trying to use the docker plugin to build/push an image to my own private registry. I have basic auth working on my registry and I can log in through the browser and see it. However, using the docker plugin with secrets (created the secrets in my drone.io repository), no matter how many times I try it won’t connect properly. Not sure what to do. I’ve tried reading other threads on this topic, but I’m sorta lost. Is the plugin documentation out of date, is the syntax I’m using wrong? Here’s my drone.yml:

name: default

steps:
- name: docker
  image: myregistry/myimage
  settings:
    debug: true
    username:
      from_secret: registry_username
    password:
      from_secret: registry_password
    repo: myregistry/myimage
    tags: latest

when using a custom registry, you must use the fully qualified repository name and you must specify your registry hostname like this:

steps:
  - name: docker  
    image: plugins/docker
    settings:
      username: kevinbacon
      password: pa55word
+     repo: index.company.com/foo/bar
+     registry: index.company.com

If your registry does not use TLS also be sure to set insecure: true

It the above tips do not work, please post the full logs so that we can see the error message and advise further.

Cool, thanks.

I added the registry key with the FQDN of the registry and that didn’t seem to help. The registry is secured using TLS and it works when pushing from another machine no problem (docker login/docker push). The logs on the registry itself say there’s an invalid authorization credential which leads me to believe the secrets aren’t working or are somehow the wrong ones? I’ve tried deleting them and recreating them a bunch of times to make sure.

Log from the registry:

can you please post your full yaml file? This error tells me that you are trying to use a private image in an image: tag and you have not provided credentials. It do not believe it is related to your use of the docker plugin, which means the sample yaml you provided previously does not show us enough information to troubleshoot this further.

edit: your sample does show you are trying to use a private image (sorry, initially I thought you were using the plugins/docker image). When using a private image in your yaml, you need to give drone credentials to pull this image. See How to pull private images with 1.0

  steps:
  - name: docker
    image: myregistry/myimage

You’re right. I don’t know why I had the image set to my own custom one. I reset it to plugin/docker and it’s working now. oof.

Thanks so much for the help!
