How to install Ansible AWX on Ubuntu 20.04

Ansible AWX is an open-source web-based solution that makes Ansible much easier to use in IT environments. It provides a web-based user interface and task engine for easy and collaborative management of Ansible. In this tutorial, we are going to install Ansible AWX on Ubuntu 20.04 LTS system.

Prerequisites

Ensure that  your Ubuntu 20.04 system has the following:

  • 4 GB of RAM
  • 3.4 GHz CPU with 2 Cores
  • Hard disk space 20 GB
  • Internet Connection

Step 1 Update your  Ubuntu System

Update your system packages to their latest versions. Run the command below:

$ sudo apt update

Step 2- Install docker-ce (community edition)

Ansible AWX services will be deployed as docker containers .We therefore need to install docker and docker-compose to run multiple container images. Docker consists of two editions  – Enterprise Edition (EE) and Community Edition (CE).

The Community Edition is free, and this is what we are going to install.

First, import the Docker repository GPG key. Run:

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Next, add the Docker Community Edition (CE) repository  to your ubuntu system:

$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu\  $ (lsb_release -cs) stable"

Next, update packages and install Docker. Run the command:

$ sudo apt update
$ sudo apt install -y docker-ce docker-ce-cli containerd.io

Once the installation is complete, add your local or regular user to the docker group so that regular user can run docker commands as a non-root user.

Run the command:

$ sudo usermod -aG docker $USER

Then restart the docker service.

$ sudo systemctl restart docker

Run the command below or  logout and login again, so that a regular user can run docker commands without sudo.

$ newgrp docker

Finally, confirm the version of docker that you have installed:

$ docker version

Step 3 Install docker-compose

Next, we are going to install docker-compose. 

Download the  docker-compose file by running:

$ curl -s https://api.github.com/repos/docker/compose/releases/latest \ | grep browser_download_url | grep docker-compose-Linux-x86_64 \| cut -d '"' -f 4 | wget -qi -

Next, make the binary file executable by running:

$ sudo chmod +x docker-compose-Linux-x86_64

Next, move the docker-compose file to the /usr/local/bin path:.

$ sudo mv docker-compose-Linux-x86_64 /usr/local/bin/docker-compose

Finally, verify the version of docker-compose installed. Run:

$ docker-compose version

From the output below, the docker-compose version installed is 1.28.6

Step 4 Install Ansible

Ansible is an open-source automation tool for cross-platform computer support. It is used for IT tasks such as application deployment, configuration management, updates on workstations and servers, cloud provisioning etc.

We will later use Ansible to deploy AWX services.

Ansible is available on  the official Ubuntu 20.04 repository. Run the command below to install the latest release:

$ sudo apt install -y ansible

To verify successful installation, check the Ansible version as shown:

$ ansible --version

Step 5 Install node and NPM (Node Package Manager)

Next,we install Node and NPM. Execute the commands below:

$ sudo apt install -y nodejs npm
$ sudo npm install npm --global

Step 6 Install and Setup Ansible AWX

You will need to install some extra packages git, pwgen and git. Run the command below to install the additional  packages:

$ sudo apt install -y python3-pip git pwgen

Next, install the docker-compose module. It should match with  your version of docker-compose.

$ sudo pip3 install docker-compose==1.28.6

Next , download the latest AWX zip file from Github. Run the wget command below:

$ wget https://github.com/ansible/awx/archive/17.1.0.zip

After the download is completed,  unzip the file as shown.

$ unzip 17.1.0.zip

Make sure to locate the  awx-17.1.0 folder in your directory. Then navigate into the installer directory inside the awx-17.1.0 folder as shown

$ cd awx-17.1.0 /installer

Next, generate a 30 character secret key using the pwgen tool as follows:

$ pwgen -N 1 -s 30

Copy the  key and save it somewhere. Next, we open the inventory file which is in the same directory.

$ vim inventory

Next, set the admin password to something more secure. You will use this password to log into AWX. 

admin_user=admin

admin_password=<Strong-Admin-password>

Additionally, modify the secret key  with the secret key generated earlier.

secret_key=siKdy33bLFP60qOCSoXBp39o39o3oAzzm

Step 7- Run the playbook file to Install AWX

In this step,  we are going to run the Ansible playbook file called install.yml as shown below:

$ ansible-playbook -i inventory install.yml

This only takes a few minutes to complete.

Step 8 Access AWX Dashboard

Open your browser and browse to the server’s IP as shown below:

http://server-ip-address

Login with the admin username and password that you set in the inventory file.

install Ansible AWX on Ubuntu

This will open the AWX dashboard as shown:

install Ansible AWX on Ubuntu

In this guide you learnt how to install Ansible AWX on Ubuntu 20.04.
