You can install a collection in a git repository by providing the URI to the repository instead of a collection name or path to a ``tar.gz`` file. The collection must contain a ``galaxy.yml`` or ``MANIFEST.json`` file, which will be used to generate the would-be collection artifact data from the directory. The URI should be prefixed with ``git+`` (or with ``git@`` to use a private repository with ssh authentication) and optionally supports a comma-separated `git commit-ish <https://git-scm.com/docs/gitglossary#def_commit-ish>`_ version (for example, a commit or tag).
.. warning::
Embedding credentials into a git URI is not secure. Make sure to use safe auth options for security reasons. For example, use `SSH <https://help.github.com/en/github/authenticating-to-github/connecting-to-github-with-ssh>`_, `netrc <https://linux.die.net/man/5/netrc>`_ or `http.extraHeader <https://git-scm.com/docs/git-config#Documentation/git-config.txt-httpextraHeader>`_/`url.<base>.pushInsteadOf <https://git-scm.com/docs/git-config#Documentation/git-config.txt-urlltbasegtpushInsteadOf>`_ in Git config to prevent your creds from being exposed in logs.
.. code-block:: bash
# Install a collection in a repository using the latest commit on the branch 'devel'
ansible-galaxy collection install git+https://github.com/organization/repo_name.git,devel
# Install a collection from a private github repository
ansible-galaxy collection install git@github.com:organization/repo_name.git
# Install a collection from a local git repository
ansible-galaxy collection install git+file:///home/user/path/to/repo/.git
In a ``requirements.yml`` file, you can also use the ``type`` and ``version`` keys in addition to using the ``git+repo,version`` syntax for the collection name.
.. code-block:: yaml
collections:
- name: https://github.com/organization/repo_name.git
type: git
version: devel
Git repositories can be used for collection dependencies as well. This can be helpful for local development and testing but built/published artifacts should only have dependencies on other artifacts.
.. code-block:: yaml
dependencies: {'git@github.com:organization/repo_name.git': 'devel'}
Default repository search locations
-----------------------------------
There are two paths searched in a repository for collections by default.
The first is the ``galaxy.yml`` or ``MANIFEST.json`` file in the top level of the repository path. If the file exists it's used as the collection metadata and the individual collection will be installed.
.. code-block:: text
├── galaxy.yml
├── plugins/
│   ├── lookup/
│   ├── modules/
│   └── module_utils/
└─── README.md
The second is a ``galaxy.yml`` or ``MANIFEST.json`` file in each directory in the repository path (one level deep). In this scenario, each directory with a metadata file is installed as a collection.
.. code-block:: text

├── docs/
├── MANIFEST.json
├── plugins/

└── roles/
Specifying the location to search for collections
-------------------------------------------------
If you have a different repository structure or only want to install a subset of collections, you can add a fragment to the end of your URI (before the optional comma-separated version) to indicate which path ansible-galaxy should inspect for metadata file(s). The path should be a directory to a collection or multiple collections (rather than the path to a ``galaxy.yml`` file or ``MANIFEST.json`` file).
