By default, ``ansible-galaxy collection install`` uses https://galaxy.ansible.com as the Galaxy server (as listed in the
:file:`ansible.cfg` file under :ref:`galaxy_server`). You do not need any
further configuration.
See :ref:`Configuring the ansible-galaxy client <galaxy_server_config>` if you are using any other Galaxy server, such as Red Hat Automation Hub.
To install a collection hosted in Galaxy:
.. code-block:: bash
ansible-galaxy collection install my_namespace.my_collection
To upgrade a collection to the latest available version from the Galaxy server you can use the ``--upgrade`` option:
.. code-block:: bash
ansible-galaxy collection install my_namespace.my_collection --upgrade
You can also directly use the tarball from your build:
.. code-block:: bash
ansible-galaxy collection install my_namespace-my_collection-1.0.0.tar.gz -p ./collections
You can build and install a collection from a local source directory. The ``ansible-galaxy`` utility builds the collection using the ``MANIFEST.json`` or ``galaxy.yml``
metadata in the directory.
.. code-block:: bash
ansible-galaxy collection install /path/to/collection -p ./collections
You can also install multiple collections in a namespace directory.
.. code-block:: text
ns/
├── collection1/
│   ├── MANIFEST.json
│   └── plugins/
└── collection2/
├── galaxy.yml
└── plugins/
.. code-block:: bash
ansible-galaxy collection install /path/to/ns -p ./collections
.. note::
The install command automatically appends the path ``ansible_collections`` to the one specified with the ``-p`` option unless the
parent directory is already in a folder called ``ansible_collections``.
When using the ``-p`` option to specify the install path, use one of the values configured in :ref:`COLLECTIONS_PATHS`, as this is
where Ansible itself will expect to find collections. If you don't specify a path, ``ansible-galaxy collection install`` installs
the collection to the first path defined in :ref:`COLLECTIONS_PATHS`, which by default is ``~/.ansible/collections``
You can also keep a collection adjacent to the current playbook, under a ``collections/ansible_collections/`` directory structure.
.. code-block:: text
./
├── play.yml
├── collections/
│ └── ansible_collections/
│ └── my_namespace/
│ └── my_collection/<collection structure lives here>
See :ref:`collection_structure` for details on the collection directory structure.
