Puppet+Docker: What is the equivalent of docker rm in Puppet code?

Question

I was looking to remove a few images. How can i achieve this using puppet code?

Answer 1

To remove an image, add the following code to the manifest file:

docker::image { 'base':

  ensure => 'absent'

}

docker::image { 'ubuntu':

  ensure    => 'absent',

  image_tag => 'precise'

}

This will act as a docker rm command.

Answer 2

First, make sure you have docker deployed using puppet in your prefered location. 

To pull a docker image :

create a <name of file>.pp file and inside it write :

docker::image { 'ubuntu':

  ensure    => 'present',

  image_tag => 'trusty'

}

type this command to run the file, it will pull the image you specified.

$ puppet apply pull_image.pp

To remove a docker image :

create a <name of file>.pp file and inside it write :

docker::image { 'ubuntu':

  ensure    => 'absent',

  image_tag => 'trusty'

}

type this command to run the file, it will remove the image you specified.

$ puppet apply rm_image.pp 

Hope this helps.
