The Docker Task Runner

Dunner is a task runner tool based on Docker, simple and flexible. You can define tasks and configure the environment in your .dunner.yaml file and then run as dunner do <taskname>.

Example .dunner.yaml:

envs:
  - AWS_ACCESS_KEY_ID=`$AWS_KEY`
  - AWS_SECRET_ACCESS_KEY=`$AWS_SECRET`
  - AWS_DEFAULT_REGION=us-east1
tasks:
  deploy:
    steps:
      - image: 'emeraldsquad/sonar-scanner'
        commands:
          - ['sonar', 'scan']
      - image: 'golang'
        commands:
          - ['go', 'install']
      - image: 'mesosphere/aws-cli'
        commands:
          - ['aws', 'elasticbeanstalk update-application --application-name myapp']
      - follow: 'status' #This refers to another task and can pass args too
        args: 'prod'
  status:
    steps:
      - image: 'mesosphere/aws-cli'
        commands:
          # This uses args passed to the task, `$1` means first arg
          - ['aws', 'elasticbeanstalk describe-events --environment-name $1']
