docker_prune not working with label

[abin stephen]

How we can configure docker_prune  to delete docker images with specific name, I have tried something below and it didt worked can you please help us to fix  this

- name: Remove unused images
  docker_prune:
    images: yes
    images_filters:
      label: appName=hello

[Felix Fontein]

Hi,

the filters you pass are passed over to docker-py
(https://docker-py.readthedocs.io/en/stable/api.html#docker.api.image.ImageApiMixin.prune_images),
which is passing it to the docker daemon via the API
(https://docs.docker.com/engine/api/v1.39/#operation/ImagePrune).

The docker-py documentation only mentions the dangling filter, while
the CLI docs
(https://docs.docker.com/engine/reference/commandline/image_prune/)
also mention the label filter you are using.

The task you've posted looks like it *should* pass the correct values
to the docker daemon.

What exactly was the problem? Did you get an error message, or was an
image simply not deleted? (And does docker CLI behave differently?)

Cheers,
Felix

Can you please confirm whether  the synatx I am using here is correct?

- name: Remove unused images

  docker_prune:
    images: yes
    images_filters:

      label: appName=hello

Hi,

I think it is correct. I've never tried prune by labels, but from
looking at the module's code, docker-py's code and docker CLI's code, I
would expect this to work.

Cheers,
Felix

its working in docker CLI  < docker image prune -a --force --filter="label=appname=helloworld" >

i want do the same with docker_prune is it possible ?

Its failing with

TASK [Run docker_compose_services role] ****************************************
ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.

The error appears to have been in '/jenkins/workspace/y_real-time-payments_master-WUPVH7HV2NXJH4IGGIT24TMVMKH2JS77LLYJC2NU762UZQBOUNEQ/roles/deploy_docker_compose_services/tasks/main.yml': line 39, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:


- name: Remove unused images
  ^ here
	to retry, use: --limit @/jenkins/workspace/y_real-time-payments_master-WUPVH7HV2NXJH4IGGIT24TMVMKH2JS77LLYJC2NU762UZQBOUNEQ/deploy_docker_compose_services.retry

Hi,

what you are reporting is not a problem with the module, but a syntax
error in writing this Ansible task. The way you posted your task to
this mailing list looked OK, but it appears that the task as used in
your role has a syntax error.

Cheers,
Felix

Is this module available in ansible 2.7.10?

[Matt Martz]

No, per the documentation which you can find at https://docs.ansible.com/ansible/latest/modules/docker_prune_module.html

It states: "New in version 2.8."
