Dunner

The Docker Task Runner

Dunner is a task runner tool like Grunt but uses Docker images like CircleCI do. You can define tasks and steps of the tasks in your .dunner.yaml file and then run these steps with dunner do <taskname>.

Example .dunner.yaml

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

Now you can use as,
