AWX stands for “Ansible Web eXecutable” is a free and open-source project that allows you to easily manage and control Ansible projects. AWX provides a web-based user interface, a powerful REST API and allows you to manage or sync inventory with other cloud sources, control access, and integrate with LDAP.
In this tutorial, we will show you how to install AWX Ansible AWX with Docker on Rocky Linux 8.3 and CentOS 8.
Precondition
- Rocky Linux 8.3 or CentOS 8 server with a minimum of 4 GB RAM.
- Log in as root or user with privileges sudo
Before Starting
Add the EPEL Repository on the system with the following command:
dnf install epel-release -y
Next, you will need to install some additional packages that are required to run AWX on the system. You can install them all with the following command:
dnf install git gcc gcc-c++ ansible nodejs gettext device-mapper-persistent-data lvm2 bzip2 python3-pip -y
Once all packages have been installed, you can move on to the next step.
Install Docker dan Docker Compose
Next, we need to install Docker to run AWX inside a Docker container. By default, the latest version of Docker is not available in the default CentOS 8 repositories.So you need to add the Docker repository on your system. You can add the Docker repository with the following command:
dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo
Once added, install the latest stable version of Docker with the following command:
dnf install docker-ce-3:18.09.1-3.el7 -y
Once Docker is installed, check which version of Docker is installed with the following command:
docker --version
You should get something like this:
Docker version 19.03.7, build 7141c199a2
Next, start the Docker service and enable it to start after the system reboots with the following command:
systemctl start docker systemctl enable docker
You can verify the status of the Docker service with the following command:
systemctl status docker
You should get something like this:
? docker.service - Docker Application Container Engine

Next, install Docker compose using the following command:
pip3 install docker-compose
Once installed, verify the Docker compose version using the following command:
docker-compose --version
You will see the following output:
docker-compose version 1.25.4, build unknown
Finally, run the following command to set the python command to use python 3:
alternatives --set python /usr/bin/python3

Install CentOS 8 Ansible AWX
First, download the latest version of Ansible AWX from the Git Hub repository using the following command:
git clone https://github.com/ansible/awx.git
Next, create a secret key to encrypt the inventory file with the following command:
openssl rand -base64 30
You will get the following output:
R + kbcDEUS8DlAftAbtWafVfLZ0lUy + Paqo3fEtep
Note : Write down the secret key that appears by copying and pasting it into a text editor, because you have to paste it in the inventory file.
Next, change to the directory awx/ installer / and edit the inventory file with a text editor nano:
cd awx/installer/ nano inventory
Change the following lines:
[all: vars] dockerhub_base = ansible awx_task_hostname = awx awx_web_hostname = awxweb postgres_data_dir = "/ var / lib / pgdocker" host_port = 80 host_port_ssl = 443 docker_compose_dir = "~ / .awx / awxcompose" pg_username = awx pg_password = awxpass pg_database = awx pg_port = 5432 pg_admin_password = password rabbitmq_password = awxpass rabbitmq_erlang_cookie = cookiemonster admin_user = admin admin_password = password create_preload_data = True secret_key = R + kbcDEUS8DlAftAbtWafVfLZ0lUy + Paqo3fEtep awx_official = true awx_alternate_dns_servers = "8.8.8.8,8.8.4.4" project_data_dir = / var / lib / awx / projects
Save and close the file when you are done. Then, Create Directory for Postgres:
mkdir /var/lib/pgdocker
Finally, run the following command to install AWX:
ansible-playbook -i inventory install.yml
After the installation has finished successfully, you should get the following output:
skipping: [localhost] TASK [local_docker : Load web image] ********************************************************************************************************** skipping: [localhost] TASK [local_docker : Load task image] ********************************************************************************************************* skipping: [localhost] TASK [local_docker : Set full image path for local install] *********************************************************************************** skipping: [localhost] TASK [local_docker : Set DockerHub Image Paths] *********************************************************************************************** ok: [localhost] TASK [local_docker : Create ~/.awx/awxcompose directory] ************************************************************************************** changed: [localhost] TASK [local_docker : Create Docker Compose Configuration] ************************************************************************************* changed: [localhost] => (item=environment.sh) changed: [localhost] => (item=credentials.py) changed: [localhost] => (item=docker-compose.yml) changed: [localhost] => (item=nginx.conf) TASK [local_docker : Render SECRET_KEY file] ************************************************************************************************** changed: [localhost] TASK [local_docker : Start the containers] **************************************************************************************************** changed: [localhost] TASK [local_docker : Update CA trust in awx_web container] ************************************************************************************ changed: [localhost] TASK [local_docker : Update CA trust in awx_task container] *********************************************************************************** changed: [localhost] PLAY RECAP ************************************************************************************************************************************ localhost : ok=14 changed=6 unreachable=0 failed=0 skipped=95 rescued=0 ignored=0
The command above will create and start all the necessary Docker containers for AWX. You can verify a running container with the following command:
docker ps
You will see the following output:

Configure SELinux and Firewall
By default, SELinux is enabled on CentOS 8. It is recommended to disable it to work AWX in Docker environment. You can disable it by editing the following file:
nano /etc/sysconfig/selinux
Find the following line:
SELINUX=enforcing
And, replace it with the following line:
SELINUX=disabled
Save and close the file when you are done. Then, restart the system to implement the changes. Next, you need to allow http and https services through firewalld. You can allow them with the following command:
firewall-cmd --zone=public --add-masquerade --permanent firewall-cmd --permanent --add-service=http firewall-cmd --permanent --add-service=https
Next, restart the firewalld service to apply the changes:
firewall-cmd --reload
AWX Web Interface Access
Now, open your web browser and type in the URL http: // domain_ or_server-ip. You will be directed to the AWX login page:
Provide your admin username and password which you have set in the inventory file and click the button SIGN IN . You will see the AWX default dashboard on the following page:
Conclusion
Congratulations! You have successfully installed AWX with Docker on Rocky linux 8.3 and CentOS 8. Now you can easily manage and control your Ansible projects using the AWX web interface.
Thank you for Rocky Linux Ansible Configure
Thank you, keep visit linuxstoney for this type of detailed and essential linux guide
After:
# pip3 install docker-compose
# docker-compose –version
bash: docker-compose: command not found
So:
# ln -s /usr/local/bin/docker-compose /bin/docker-compose
[root@osboxes osboxes]# docker-compose –version
docker-compose version 1.29.2, build unknown
Will fix the issue.
Also, this guide is going to work for version lower than 18.0.0, otherwise AWX operator for K8s is the recommended way to installation or Docker development can be setup as well:
