Using modules from the yang Collection in your playbooks

It's preferable to use content in this collection using their Fully Qualified Collection Namespace (FQCN), for example community.yang.configure:

---
- hosts: iosxr
  gather_facts: false
  connection: ansible.netcommon.netconf

  tasks:
    - name: "Fetch given yang model and all the dependent models from remote host"
      community.yang.fetch:
        name: Cisco-IOS-XR-ifmgr-cfg

    - name: get interface configuration in json/xml format
      community.yang.get:
        filter: |
          <interface-configurations xmlns="http://cisco.com/ns/yang/Cisco-IOS-XR-ifmgr-cfg"><interface-configuration>
          </interface-configuration></interface-configurations>
        file: "./files/cisco/iosxr/*.yang"
        search_path: "./files/cisco/iosxr"
      register: result

    - name: Configure interface description providing json input file
      community.yang.configure:
        config: "{{ lookup('file', config_file) }}"
        file: "{{ yang_file }}"
        search_path: "{{ search_path }}"
      register: result

    - name: Configure interface description with json input
      community.yang.configure:

For documentation on how to use individual modules and other content included in this collection, please see the links in the 'Included content' section earlier in this README.

Testing and Development

If you want to develop new content for this collection or improve what's already here, the easiest way to work on the collection is to clone it into one of the configured COLLECTIONS_PATHS, and work on it there.

Testing with ansible-test

The tests directory contains configuration for running sanity and integration tests using ansible-test.

To run these network integration tests, use ansible-test network-integration --inventory </path/to/inventory> <tests_to_run>:

ansible-test network-integration  --inventory ~/myinventory -vvv <name of the plugin>

Publishing New Versions

Releases are automatically built and pushed to Ansible Galaxy for any new tag. Before tagging a release, make sure to do the following:

1. Update galaxy.yml and this README's requirements.yml example with the new version for the collection.
2. Update the CHANGELOG: 1. Make sure you have antsibull-changelog installed. 2. Make sure there are fragments for all known changes in changelogs/fragments. 3. Run antsibull-changelog release.
3. Commit the changes and create a PR with the changes. Wait for tests to pass, then merge it once they have.
4. Tag the version in Git and push to GitHub.

After the version is published, verify it exists on the Ansible Yang Community Collection Galaxy page.
