Ansible AWX - Basic Install Example @ RHEL 7

1. Enable proper repositories:

subscription-manager repos --disable="*" \
                           --enable=rhel-7-server-rpms \
                           --enable=rhel-7-server-extras-rpms

2. Update the system and install prerequisites:

yum update -y
yum install docker docker-python git ansible vim bash-completion
reboot

3. Configure and enable Docker Engine:

docker-storage-setup 
systemctl enable docker
systemctl start docker

4. Clone the Ansible AWX Github repositories (use the latest release branch):

cd /root/
git clone https://github.com/ansible/awx.git

5. At the awx/installer directory, edit inventory file with the content:

localhost ansible_connection=local ansible_python_interpreter="/usr/bin/env python"

[all:vars]

# Version of AWX container images
dockerhub_base=ansible
dockerhub_version=latest

# Common Docker parameters
postgres_data_dir=/var/lib/awx/pgdocker
host_port=80

# Docker Compose Variable
docker_compose_dir=/var/lib/awx

# Local PostgreSQL Variables
pg_username=awx
pg_password=awxpass
pg_database=awx
pg_port=5432

# Default AWX admin (superuser) account
default_admin_user=admin
default_admin_password='r3dh4t1!'

# AWX Secret key
secret_key='changemeplz'

# Proxy
#http_proxy=http://proxy:3128
#https_proxy=http://proxy:3128
#no_proxy=mycorp.org

# AWX project data folder.
project_data_dir=/var/lib/awx/projects

6. Run the AWX installer playbook:

cd awx/installer/
ansible-playbook -i inventory install.yml

I get this error:
TASK [local_docker : Start the containers] **************************************
fatal: [localhost]: FAILED! => {"changed": false, "msg": "Unable to load docker-compose. Try pip install docker-compose. Error: No module named compose"}
to retry, use: --limit @/root/awx/installer/install.retry

First ERROR encountered at step 6 after following first 5 steps correctly. Please advise.

First ERROR encountered at step 6 after following first 5 steps correctly. Please advise.

use python3 instead of python2. changing the python version in /etc/alternatives will not work. You have to manually link python3 as the default version.
unlink /usr/bin/python
ln -s /usr/bin/python3 /usr/bin/python

I am also getting similar error despite setting default python version to python3 using :
unlink /usr/bin/python
ln -s /usr/bin/python3 /usr/bin/python
