# Ansible OpenStack Collection

Ansible OpenStack collection aka `openstack.cloud` provides Ansible modules and Ansible plugins for managing OpenStack
clouds. It is supported and maintained by the OpenStack community.

## Branches and Non Backward Compatibility ⚠️

Our codebase has been split into two separate release series, `2.x.x` and `1.x.x`:

* `2.x.x` releases of Ansible OpenStack collection are compatible with [OpenStack SDK][openstacksdk] `1.x.x` and its
  release candidates `0.99.0` and later *only* (OpenStack Zed and later). Our `master` branch tracks our `2.x.x`
  releases.
* `1.x.x` releases of Ansible OpenStack collection are compatible with [OpenStack SDK][openstacksdk] `0.x.x` prior to
  `0.99.0` *only* (OpenStack Yoga and earlier). Our `stable/1.0.0` branch tracks our `1.x.x` releases.
* `2.x.x` releases of Ansible OpenStack collection are not backward compatible to `1.x.x` releases ⚠️

For rationale and details please read our [branching docs](docs/branching.md). Both branches will be developed in
parallel for the time being. Patches from `master` will be backported to `stable/1.0.0` on a best effort basis but
expect new features to be introduced in our `master` branch only. Contributions are welcome for both branches!

## Installation

For using this collection, first you have to install both Python packages `ansible` and `openstacksdk` on your Ansible
controller:

```sh
pip install "ansible>=2.9" "openstacksdk>=0.36,<0.99.0"
```

[OpenStack SDK][openstacksdk] has to be available on the Ansible host running the OpenStack modules. Depending on the
Ansible playbook and roles you use, this host is not necessarily the Ansible controller. Sometimes Ansible might invoke
a non-standard Python interpreter on the target Ansible host. Using Python 3.6 is required for modules in this
collection.

Always use the last stable version of [OpenStack SDK][openstacksdk] if possible, also when running against older
OpenStack deployments. OpenStack SDK is backward compatible to older OpenStack deployments, so its safe to run last
version of the SDK against older OpenStack clouds. The installed version of the OpenStack SDK does not have to match
your OpenStack cloud, but it has to match the release series of this collection which you are using. For notes about
our release series and branches please read the introduction above.

Before using this collection, you have to install it with `ansible-galaxy`:

```sh
ansible-galaxy collection install openstack.cloud
```

You can also include it in a `requirements.yml` file:

```yaml
collections:
- name: openstack.cloud
```

And then install it with:

```sh
ansible-galaxy collection install -r requirements.yml
```

## Usage

To use a module from the OpenStack Cloud collection, please reference the full namespace, collection name, and module
name that you want to use:

```yaml
---
- name: Using OpenStack Cloud collection
  hosts: localhost
  tasks:
    - openstack.cloud.server:
        name: vm
        state: present
        cloud: openstack
        region_name: ams01
        image: Ubuntu Server 14.04
        flavor_ram: 4096
        boot_from_volume: True
        volume_size: 75
```

Or you can add the full namespace and collection name in the `collections` element:

```yaml
---
- name: Using the Ansible OpenStack Collection
  hosts: localhost
  collections:
    - openstack.cloud
  tasks:
    - server_volume:
        state: present
        cloud: openstack
        server: Mysql-server
        volume: mysql-data
        device: /dev/vdb
```

[Ansible module defaults][ansible-module-defaults] are supported as well:

```yaml
---
- module_defaults:
    group/openstack.cloud.openstack:
      cloud: devstack-admin
    #
    #
    # Listing modules individually is required for
    # backward compatibility with Ansible 2.9 only
    openstack.cloud.compute_flavor_info:
      cloud: devstack-admin
    openstack.cloud.server_info:
      cloud: devstack-admin
  block:
    - name: List compute flavors
      openstack.cloud.compute_flavor_info:

    - name: List servers
      openstack.cloud.server_info:
```
