Install Docker On Redhat 7

Ansible Tower (formerly ‘AWX') is a web-based solution that makes Ansible even more easy to use for IT teams of all kinds. It's designed to be the hub for all of your automation tasks.

1. Step 3: Install Docker on RHEL 7 Server / Desktop. We can now Install Docker on RHEL 7 by running the commands below. Sudo yum install -y docker device-mapper-libs device-mapper-event-libs sudo systemctl enable -now docker.service. Confirm service status.
2. Use podman, skopeo, and buildah to work with containers in Red Hat Enterprise Linux 7 and RHEL Atomic Host Red Hat Atomic Host Documentation Team appinfra-docs@redhat.com Legal Notice.
3. With everything set, you can finally move on to installing Docker on CentOS 7 by running: sudo yum install docker. The system should begin the installation. Once it finishes, it will notify you the installation is complete and which version of Docker is now running on your system.

Tower allows you to control access to who can access what, even allowing sharing of SSH credentials without someone being able to transfer those credentials. Inventory can be graphically managed or synced with a wide variety of cloud sources. It logs all of your jobs, integrates well with LDAP, and has an amazing browsable REST API. Command line tools are available for easy integration with Jenkins as well. Provisioning callbacks provide great support for autoscaling topologies.

How to install and use Docker on RHEL 7 or CentOS 7 (method 1) The procedure to install Docker is as follows: Open the terminal application or login to the remote box using ssh command: ssh user@remote-server-name; Type the following command to install Docker via yum provided by Red Hat: sudo yum install docker. Yum install -y yum-utils device-mapper-persistent-data lvm2 ansible git python-devel python-pip python-docker-py vim-enhanced. Pip install cryptography pip install jsonschema pip install docker-compose=1.23.0 pip install docker –upgrade. Configure docker ce stable repository. Yum-config-manager -add-repo https://download.

AWX provides a web-based user interface, REST API, and task engine built on top of Ansible. It is the upstream project for Tower, a commercial derivative of AWX.

Prerequisites

Before you can run a deployment, you'll need the following installed in your local environment:

• Ansible Requires Version 2.8+
• Docker
  • A recent version
• docker Python module
  • This is incompatible with docker-py. If you have previously installed docker-py, please uninstall it.
  • We use this module instead of docker-py because it is what the docker-compose Python module requires.
• Git Requires Version 1.8.4+
• Python 3.6+
• Node 10.x LTS version
  • This is only required if you're building your own container images with use_container_for_build=false
• NPM 6.x LTS
  • This is only required if you're building your own container images with use_container_for_build=false

System Requirements

The system that runs the AWX service will need to satisfy the following requirements

• At least 4GB of memory
• At least 2 cpu cores
• At least 20GB of space
• Running Docker, Openshift, or Kubernetes
• If you choose to use an external PostgreSQL database, please note that the minimum version is 10+.

Installation steps:

1. Install Dependencies

yum install -y epel-release

yum remove python-docker-py

yum install -y yum-utils device-mapper-persistent-data lvm2 ansible git python-devel python-pip python-docker-py vim-enhanced

pip install cryptography
pip install jsonschema
pip install docker-compose~=1.23.0
pip install docker –upgrade

2. Install docker

Configure docker ce stable repository.

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

2. Install docker

Configure docker ce stable repository.

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

Installing docker.

yum install docker-ce -y

Start docker service.

systemctl start docker

Enable docker service.

systemctl enable docker

3. Deploy AWX

Clone AWX repo

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

Clone commercial logos

cd awx/

git clone https://github.com/ansible/awx-logos.git

Configure AWX

cd installer/

$ vim inventory

awx_official=true

Deploy AWX

ansible-playbook -i inventory install.yml -vv

Check the status

docker ps -a

AWX is ready and can be accessed from the browser.

http://ipaddress:80/

the default username is 'admin' and the password is 'password'.

Final checks:

1. verify whether the service is started or not with ss -tlnp | grep 80
2. make sure your firewall is open for port 80
3. make sure your OS is using python 3.6+ and pip3
