Docker Login Buildkite Plugin

A Buildkite plugin to login to docker registries.

Securing your password

To avoid leaking your docker password to buildkite.com or anyone with access to build logs, you need to avoid including it in pipeline.yml. This means it needs to be set specifically with an environment variable in an Agent hook, or made available from a previous plugin defined on the same step.

Securing your password between Buildkite Jobs

The Elastic CI Stack for AWS automatically creates a per-job DOCKER_CONFIG directory
which is cleaned up after the job. If you are using this plug-in with another agent orchestration
tool, consider whether you need a per-job DOCKER_CONFIG too.

Example

# environment or pre-command hook
export MY_DOCKER_LOGIN_PASSWORD=mysecretpassword

steps:
  - command: ./run_build.sh
    plugins:
      - docker-login#v2.1.0:
          username: myuser
          password-env: MY_DOCKER_LOGIN_PASSWORD

Options

username

The username to send to the docker registry.

server (optional)

The server to log in to, if blank or ommitted logs into Docker Hub.

password-env

The environment variable that the password is stored in.

Defaults to DOCKER_LOGIN_PASSWORD.

retries (optional)

Retries login after a delay N times. Defaults to 0.

Windows Issues

This plugin requires git-bash, not the Windows built-in bash.exe, so you'll need to set your system PATH to have git-bash bin directory first, normallly C:\Program Files\git\bin.
