Collection Workflows

Pulp organizes role content into repositories, and you associate the ansible-galaxy client with one or more repositories. From a high level you can:

  1. Create a repo <create-a-collection-repository>
  2. Create a distribution <create-distribution-for-collection> expose that repository at a URL
  3. Sync content from galaxy.ansible.com <create-collection-remote>
  4. Install content from the repo with ansible-galaxy <ansible-galaxy-collections-cli>

Create a Repository

Create a repository and name it the foo repository.

# Start by creating a new repository named foo
pulp ansible repository create --name "foo"

Repository create output:

{
  "pulp_href": "/pulp/api/v3/repositories/ansible/ansible/b17950e8-cee8-493a-b735-0d04905cf067/",

Reference (pulpcore): Repository API Usage

Create a Distribution for Repository 'foo'

This will make the latest Repository Version content available for ansible-galaxy` clients. Each distribution names the url it can be accessed from on an attribute called ``client_url. The client_url can be used with the ansible-galaxy client with the -s option. See the ansible-galaxy-roles-cli docs for more details.

For example a distribution with base_path set to my_content could have a URL like:

http://pulp.example.com/pulp_ansible/galaxy/my_content/
# Distributions are created asynchronously. Create one, and specify the repository that will
# be served at the base path specified.
pulp ansible distribution create --name "baz" --base-path "my_content" --repository "foo"

Distribution create output:

Started background task /pulp/api/v3/tasks/48d187f6-d1d0-4d83-b803-dae9fe976da9/
.Done.
{
  "pulp_href": "/pulp/api/v3/distributions/ansible/ansible/148ce745-3dd5-4dda-a0ba-f9c5ec7119e1/",

  "repository_version": null,
  "client_url": "http://pulp3-source-fedora31.localhost.example.com/pulp_ansible/galaxy/my_content/"
}

Create a Distribution for a RepositoryVersion (optional)

Instead of always distributing the latest RepositoryVersion, you can also specify a specific RepositoryVersion for a Distribution. This should be used in place of the distribution above, not in addition to it.

# Distributions are created asynchronously. Create one, and specify the repository version that will
# be served at the base path specified.
pulp ansible distribution create --name "bar" --base-path "some_content" --repository "foo" --version 0

Distribution create output:

Started background task /pulp/api/v3/tasks/48d187f6-d1d0-4d83-b803-dae9fe976da9/
.Done.

  "pulp_href": "/pulp/api/v3/distributions/ansible/ansible/148ce745-3dd5-4dda-a0ba-f9c5ec7119e1/",

  "repository": null,

  "client_url": "http://pulp3-source-fedora31.localhost.example.com/pulp_ansible/galaxy/my_content/"
}

Create a CollectionRemote

Creating a CollectionRemote object allows Pulp to sync Collections from an external content source. This is most commonly is https://galaxy.ansible.com/ or another pulp_ansible instance.

In this example we will be syncing the Collection with namespace=testing and name=ansible_testing_content from https://galaxy-dev.ansible.com/.

# Create a remote that syncs some versions of django into your repository.
pulp ansible remote -t "collection" create \
    --name "cbar" \
    --url "https://galaxy-dev.ansible.com/" \
    --requirements $'collections:\n  - testing.ansible_testing_content'
# If requirements are in a file
# you can use the option '--requirements @<file_name>' instead.

Remote create output:

{
  "pulp_href": "/pulp/api/v3/remotes/ansible/collection/80ba27e3-b4d6-4ddb-9677-9e40c04352ef/",
  "pulp_created": "2021-01-26T23:16:06.790367Z",
  "name": "cbar",
  "url": "https://galaxy-dev.ansible.com/",
  "ca_cert": null,
  "client_cert": null,
  "client_key": null,
  "tls_validation": true,
  "proxy_url": null,
  "username": null,
  "password": null,
  "pulp_last_updated": "2021-01-26T23:16:06.790390Z",

  "policy": "immediate",
  "total_timeout": null,
  "connect_timeout": null,
  "sock_connect_timeout": null,
  "sock_read_timeout": null,
  "requirements_file": "collections:\n  - testing.ansible_testing_content",
  "auth_url": null,
  "token": null,
  "rate_limit": null
}

For remote sources that require authentication, tokens can be used. You can provide the token and/or auth_url.

In this example we will be syncing the Collection with namespace=testing and name=ansible_testing_content from https://cloud.redhat.com/api/automation-hub/v3/collections/testing/ansible_testing_content.

# Create a remote that syncs some versions of django into your repository.
pulp ansible remote -t "collection" create \
    --name "abar" \
    --auth-url "https://sso.qa.redhat.com/auth/realms/redhat-external/protocol/openid-connect/token" \
    --token "$ANSIBLE_TOKEN_AUTH" \
    --tls-validation false \
    --url "https://cloud.redhat.com/api/automation-hub/" \
    --requirements $'collections:\n  - testing.ansible_testing_content'

  "rate_limit": null
}

Sync Repository foo with CollectionRemote

Use the CollectionRemote object to kick off a synchronize task by specifying the Repository to sync with. You are telling Pulp to fetch Collection content from the external source.

# Sync repository foo using remote cbar
pulp ansible repository sync --name "foo" --remote "cbar"

# Use the -b option to have the sync task complete in the background
# e.g. pulp -b ansible repository sync --name "foo" --remote "cbar"

# After the task is complete, it gives us a new repository version
# Inspecting new repository version
pulp ansible repository version show --repository "foo"

Repository Version GET Response (when complete):

      }
    }
  }
}

Install a Collection, hosted by Pulp, using ansible-galaxy

You can use ansible-galaxy to install a collection by its namespace and name from pulp_ansible using the install command. For example to install the hello collection from above into a directory ~/collections you can specify:

ansible-galaxy collection install testing.ansible_testing_content -c -s http://localhost/pulp_ansible/galaxy/my_content/

This assumes that the hello Collection is being served by the Distribution ansible-galaxy is configured to use.

Using a specific version

Install your collection by name by specifying the distribution serving your Repository's content using the -s option.

ansible-galaxy collection install testing.ansible_testing_content:4.0.6 -c -s http://localhost/pulp_ansible/galaxy/my_content/

Note: the -c flag tells ansible-galaxy to ignore self signed https certificates.

Configuring ansible-galaxy

Use the ansible-galaxy config files to specify the distribution ansible-galaxy should interact with. To use this, set up your distribution in your ansible config (e.g. ~/.ansible.cfg or /etc/ansible/ansible.cfg):

[galaxy]
server_list = pulp, my_fallback_server

[galaxy_server.pulp]
url = http://localhost/pulp_ansible/galaxy/my_content/

[galaxy_server.my_fallback_server]
url = http://localhost/pulp_ansible/galaxy/my_other_content/
username = my_user
password = my_password

[galaxy_server.deprecated]
url = http://localhost/pulp_ansible/galaxy/deprecated/
username = my_user
password = my_password

Servers will be used in the order that they appear in server_list in the configuration file. Specific servers can also be specified using the -s (or --server) flag, either by their name or URL. In this example ansible-galaxy will attempt to fetch content from pulp and fallback to my_fallback_server if it can't find anything. The deprecated server is not listed under server_list, so ansible-galaxy won't pull content from it unless the server is specified explicitly with the -s flag.

# Downloads from the "pulp" server
ansible-galaxy collection install testing.ansible_testing_content:4.0.6

# Downloads from the "deprecated" server
ansible-galaxy collection install testing.ansible_testing_content:4.0.6 -s deprecated

Publish (Upload) a Collection

You can use ansible-galaxy to publish any built artifact to pulp_ansible by running:

ansible-galaxy collection build  # from inside the root directory of the collection
ansible-galaxy collection publish path/to/artifact.tar.gz

For example if you have ansible-galaxy installed and configured the script below will upload a Collection to pulp_ansible and display it:

ansible-galaxy collection init namespace_name.collection_name
ansible-galaxy collection build namespace_name/collection_name/
ansible-galaxy collection publish namespace_name-collection_name-1.0.0.tar.gz -c

The client upload the Collection to the Repository associated with the Distribution. Each upload creates a new Repository Version for the Repository.
