If you have not already done so, you will need to clone, or create a local copy, of the [AWX repo](https://github.com/ansible/awx). For more on how to clone the repo, view [git clone help](https://git-scm.com/docs/git-clone).
Once you have a local copy, run commands within the root of the project tree.
You can optionally install the AWX branding assets from the [awx-logos repo](https://github.com/ansible/awx-logos). Prior to installing, please review and agree to the [trademark guidelines](https://github.com/ansible/awx-logos/blob/master/TRADEMARKS.md).
To install the assets, clone the `awx-logos` repo so that it is next to your `awx` clone. As you progress through the installation steps, you'll be setting variables in the [inventory](./installer/inventory) file. To include the assets in the build, set `awx_official=true`.
We currently support running AWX as a containerized application using Docker images deployed to either an OpenShift cluster, or a standalone Docker daemon. The remainder of this document will walk you through the process of building the images, and deploying them to either platform.
The [installer](./installer) directory contains an [inventory](./installer/inventory) file, and a playbook, [install.yml](./installer/install.yml). You'll begin by setting variables in the inventory file according to the platform you wish to use, and then you'll start the image build and deployment process by running the playbook.
In the sections below, you'll find deployment details and instructions for each platform. To deploy to Docker, view the [Docker section](#docker), and for OpenShift, view the [OpenShift section](#openshift).
## OpenShift
### Prerequisites
To complete a deployment to OpenShift, you will obviously need access to an OpenShift cluster. For demo and testing purposes, you can use [Minishift](https://github.com/minishift/minishift) to create a single node cluster running inside a virtual machine.
You will also need to have the `oc` command in your PATH. The `install.yml` playbook will call out to `oc` when logging into, and creating objects on the cluster.
The Minishift VM contains a Docker daemon, which you can use to build the AWX images. This is generally the approach you should take, and we recommend doing so. To use this instance, run the following command to setup your environment:
> If you choose to not use the Docker instance running inside the VM, and build the images externally, you will have to enable the OpenShift cluster to access the images. This involves pushing the images to an external Docker registry, and granting the cluster access to it, or exposing the internal registry, and pushing the images into it.
Before starting the build process, review the [inventory](./installer/inventory) file, and uncomment and provide values for the following variables found in the `[all:vars]` section:
> IP address and port, or URL, for accessing a registry that the OpenShift cluster can access. Defaults to *172.30.1.1:5000*, the internal registry delivered with Minishift.
AWX requires access to a PostgreSQL database, and by default, one will be created and deployed in a pod. The database is configured for persistence and will create a persistent volume claim named `postgresql`. By default it will claim 5GB from the available persistent volume pool. This can be tuned by setting a variable in the inventory file or on the command line during the `ansible-playbook` run.
If you wish to use an external database, in the inventory file, set the value of `pg_hostname`, and update `pg_username`, `pg_password`, `pg_database`, and `pg_port` with the connection information. When setting `pg_hostname` the installer will assume you have configured the database in that location and will not launch the postgresql pod.
To start the build, you will pass two *extra* variables on the command line. The first is *openshift_password*, which is the password for the *openshift_user*, and the second is *docker_registry_password*, which is the password associated with *docker_registry_username*.
If you're using the OpenShift internal registry, then you'll pass an access token for the *docker_registry_password* value, rather than a password. The `oc whoami -t` command will generate the required token, as long as you're logged into the cluster via `oc cluster login`.
After the playbook run completes, check the status of the deployment by running `oc get pods`:
```bash
# View the running pods
$ oc get pods
NAME READY STATUS RESTARTS AGE
awx-3886581826-5mv0l 4/4 Running 0 8s
postgresql-1-l85fh 1/1 Running 0 20m
```
In the above example, the name of the AWX pod is `awx-3886581826-5mv0l`. Before accessing the AWX web interface, setup tasks and database migrations need to complete. These tasks are running in the `awx_task` container inside the AWX pod. To monitor their status, tail the container's STDOUT by running the following command, replacing the AWX pod name with the pod name from your environment:
```bash
# Follow the awx_task log output
$ oc logs -f awx-3886581826-5mv0l -c awx-celery
```
You will see the following indicating that database migrations are running:
The deployment process creates a route, `awx-web-svc`, to expose the service. How the ingres is actually created will vary depending on your environment, and how the cluster is configured. You can view the route, and the external IP address and hostname assigned to it, by running the following command:
The above example is taken from a Minishift instance. From a web browser, use `https` to access the `HOST/PORT` value from your environment. Using the above example, the URL to access the server would be [https://awx-web-svc-awx.192.168.64.2.nip.io](https://awx-web-svc-awx.192.168.64.2.nip.io).
Once you access the AWX server, you will be prompted with a login dialog. The default administrator username is `admin`, and the password is `password`.
By default, the delivered [installer/inventory](./installer/inventory) file will deploy AWX to the local host. It is possible; however, to deploy to a remote host. The [installer/install.yml](./installer/install.yml) playbook can be used to build images on the local host, and ship the built images to, and run deployment tasks on, a remote host. To do this, modify the [installer/inventory](./installer/inventory) file, by commenting out `localhost`, and adding the remote host.
For example, suppose you wish to build images locally on your CI/CD host, and deploy them to a remote host named *awx-server*. To do this, add *awx-server* to the [installer/inventory](./installer/inventory) file, and comment out or remove `localhost`, as demonstrated by the following:
In the above example, image build tasks will be delegated to `localhost`, which is typically where the clone of the AWX project exists. Built images will be archived, copied to remote host, and imported into the remote Docker image cache. Tasks to start the AWX containers will then execute on the remote host.
**Note**
> You may also want to set additional variables to control how Ansible connects to the host. For more information about this, view [Behavioral Inventory Parameters](http://docs.ansible.com/ansible/latest/intro_inventory.html#id12).
> When deploying to a remote host, the playook does not execute tasks with the `become` option. For this reason, make sure the user that connects to the remote host has privileges to run the `docker` command. This typically means that non-privileged users need to be part of the `docker` group.
Before starting the build process, review the [inventory](./installer/inventory) file, and uncomment and provide values for the following variables found in the `[all:vars]` section:
*postgres_data_dir*
> If you're using the default PostgreSQL container (see [PostgreSQL](#postgresql-1) below), provide a path that can be mounted to the container, and where the database can be persisted.
AWX requires access to a PostgreSQL database, and by default, one will be created and deployed in a container, and data will be persisted to a host volume. In this scenario, you must set the value of `postgres_data_dir` to a path that can be mounted to the container. When the container is stopped, the database files will still exist in the specified path.
If you wish to use an external database, in the inventory file, set the value of `pg_hostname`, and update `pg_username`, `pg_password`, `pg_database`, and `pg_port` with the connection information.
### Start the build
If you are not pushing images to a Docker registry, start the build by running the following:
If you're pushing built images to a repository, then use the `-e` option to pass the registry password as follows, replacing *password* with the password of the username assigned to `docker_registry_username`:
After the playbook run completes, Docker will report up to 5 running containers. If you chose to use an existing PostgresSQL database, then it will report 4. You can view the running containers using the `docker ps` command, as follows:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

97e196120ab3 postgres:9.6 "docker-entrypoint..." 2 minutes ago Up 2 minutes 5432/tcp postgres
```
Immediately after the containers start, the *awx_task* container will perform required setup tasks, including database migrations. These tasks need to complete before the web interface can be accessed. To monitor the progress, you can follow the container's STDOUT by running the following:
Apply all migrations: sso, taggit, sessions, djcelery, sites, kombu_transport_django, social_auth, contenttypes, auth, conf, main
Synchronizing apps without migrations:

### Accessing AWX
The AWX web server is accessible on the deployment host, using the *host_port* value set in the *inventory* file. The default URL is [http://localhost](http://localhost).
You will prompted with a login dialog. The default administrator username is `admin`, and the password is `password`.
