Integration of Docker with Ansible !!!

Integration of Docker with Ansible (Task 10)

Write an Ansible Playbook for Docker operations in the managed node

1. Configure Docker
2. Start and enable Docker services
3. Pull the httpd server image from the Docker Hub
4. Run the httpd container and expose it to the public
5. Copy the html code in /var/www/html directory and start the web

What is Ansible ?

• Ansible is an open-source software provisioning, configuration management, and application-deployment tool enabling infrastructure as code. It runs on many Unix-like systems, and can configure both Unix-like systems as well as Microsoft Windows. It includes its own declarative language to describe system configuration.

What is Docker ?

• Docker is an open-source project for automating the deployment of applications as portable, self-sufficient containers that can run on the cloud or on-premises. Docker is also a company that promotes and evolves this technology, working in collaboration with cloud, Linux, and Windows vendors, including Microsoft.

Pre-requisites:

• For the integratiom of Ansible with Docker we require two redhat8 os with yum configuration
• * Controller Node
• * Managed Node

So let's Start.......

So first we have to start both the os ..then go to the controller node and install the ansible . Ansible tool work on the python thus to install the ansible we have to use the pip3 command

command : pip3 install ansible

Then we have check wether the Ansible is install or not .For checking

command : ansible --version

Now we have to go at managed node ..and check the IP of the managed node

When we can get the IP of managed node then go to the controller node and create the inventory file

After that create the configuration file by using the command :

" cd /etc/ansible/"name_of_file".cfg "

Now check the connection between the controller node and managed node by using the command : ansible all -m ping

Then start the ansible-playbook

First we need the docker repository. For creating the repository we have download the docker package from the baseurl

Then we have install the docker_package

After installing the package we have to start the docker service

Then we have install the python software and python package for the docker

Then to run the container we need image ...so pull the image

And now we have create the docker container

Then the web page which we can copy in managed node copy to the apache webserver directory

 Now we have to start the docker service

Lets see the outputs :

And finally check the docker service at managed node started or not

Lets check the output of webpages :

And finally Task completed successfully...

Thank you Mr. Vimal Daga sir ..
