pulp_docker Plugin

This is the pulp_docker Plugin for Pulp Project 3.0+. This plugin provides Pulp with support for docker images, similar to the pulp_docker plugin for Pulp 2.

All REST API examples below use httpie to perform the requests.

machine localhost
login admin
password admin

If you configured the admin user with a different password, adjust the configuration accordingly. If you prefer to specify the username and password with each request, please see httpie documentation on how to do that.

This documentation makes use of the jq library to parse the json received from requests, in order to get the unique urls generated when objects are created. To follow this documentation as-is please install the jq library with:

$ sudo dnf install jq

Create a repository foo

$ http POST http://localhost:8000/pulp/api/v3/repositories/ name=foo

{
    "_href": "/pulp/api/v3/repositories/1/",
    ...
}

$ export REPO_HREF=$(http :8000/pulp/api/v3/repositories/ | jq -r '.results[] | select(.name == "foo") | ._href')

Create a new remote bar

    ...
}

$ export REMOTE_HREF=$(http :8000/pulp/api/v3/remotes/docker/docker/ | jq -r '.results[] | select(.name == "dockerhub/busybox") | ._href')

Sync repository foo using Remote bar

$ http POST ':8000'$REMOTE_HREF'sync/' repository=$REPO_HREF

Look at the new Repository Version created

$ http GET ':8000'$REPO_HREF'versions/1/'

{
    "_added_href": "/pulp/api/v3/repositories/1/versions/1/added_content/",
