Installation and Usage

Installing the Collection from Ansible Galaxy

Before using the Community Yang collection, you need to install it with the ansible-galaxy CLI:

ansible-galaxy collection install ansible.yang

You can also include it in a requirements.yml file and install it via ansible-galaxy collection install -r requirements.yml using the format:

---
collections:
  - name: ansible.yang
  - name: community.yang

Platforms test against

1. Cisco IOSXR 6.1.3

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 ansible.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"
      ansible.yang.fetch:
        name: Cisco-IOS-XR-ifmgr-cfg

    - name: get interface configuration in json/xml format
      ansible.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
      ansible.yang.configure:
        config: "{{ lookup('file', config_file) }}"
        file: "{{ yang_file }}"
        search_path: "{{ search_path }}"
      register: result

    - name: Configure interface description with json input
      ansible.yang.configure:
        config:
          {
              "Cisco-IOS-XR-ifmgr-cfg:interface-configurations": {
                  "interface-configuration": [

                              null
                          ],

                      },

                      }
                  ]
              }
          }
        file: "{{ yang_file }}"
        search_path: "{{ search_path }}"
      register: result

    - name: generate spec from open-config interface yang model data and represent in xml, json and yang tree
      ansible.yang.generate_spec:
        file: "{{ spec_yang_file }}"
        search_path: "{{ spec_search_path }}"
        doctype: config

          defaults: True

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.
