Basic Ansible Galaxy proxy support (collections) - 0.1.0

[l3ender]

Overview

This PR adds basic support for proxying Ansible Galaxy repositories through NXRM.

It has been tested with:

• Remote server URL https://galaxy.ansible.com/.
• ansible-galaxy client 2.10.3 with python version 3.9.1 on Mac OS.
• Installation of collections (untested with roles).

Usage

1. Copy the plugin .kar to {nexus_home}/deploy directory.
2. Configure the proxy repository:
3. Provide the repository endpoint when using the ansible-galaxy client:

   ansible-galaxy collection install azure.azcollection -s http://localhost:8081/repository/ansible/

Verification

After running the above collection install command:

• the repository browser will have the following components/assets:
• the NXRM HTTP request log will show the following requests were handled:

Limitations

This basic implementation is a starting point. The following details limitations of this release:

• Installing roles (not implemented).
• Using a self-hosted Ansible Galaxy server/API (should work, but untested).
• Browsing the repo in the UI is not implemented (errors are thrown when selecting assets).
