Integrating Ansible and Docker for a CI/CD Pipeline Using Jenkins

In this guide, we will use Ansible as a Deployment tool in a Continuous Integration/Continuous Deployment process using Jenkins Job.

In this guide, we will use Ansible as a Deployment tool in a Continuous Integration/Continuous Deployment process using Jenkins Job.

In the world of CI/CD process, Jenkins is a popular tool for provisioning development/production environments as well as application deployment through pipeline flow. Still, sometimes, it gets overwhelming to maintain the application's status, and script reusability becomes harder as the project grows.

To overcome this limitation, Ansible plays an integral part as a shell script executor, which enables Jenkins to execute the workflow of a process.

Let us begin the guide by installing Ansible on our Control node.

Install and Configure Ansible

Installing Ansible:

Here we are using CentOS 8 as our Ansible Control Node. To install Ansible, we are going to use python2-pip, and to do so, first, we have to install python2. Use the below-mentioned command to do so:

## sudo yum update
## sudo yum install python2

After Python is installed on the system, use pip2 command to install Ansible on the Control Node:

## sudo pip2 install ansible
## sudo pip2 install docker

It might take a minute or two to complete the installation, so sit tight. Once the installation is complete, verify:

## ansible --version

ansible 2.9.4
  config file = None
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.16 (default, Nov 17 2019, 00:07:27) [GCC 8.3.1 20190507 (Red Hat 8.3.1-4)]

Through the above command, we notice that the config file path is missing, which we will create and configure later. For now, let’s move to the next section.

Travis CI vs Jenkins: Which CI/CD Tool Is Right For You?

The ultimate showdown between Travis CI vs Jenkins. Check out this guide to know who wins the race! Travis CI and Jenkins are both popular CI/CD tools and were launched in the same year i.e. 2011. As of July 2020, Jenkins has been the more obvious choice as CI/CD tool with 15.9k stars & 6.3k forks, in comparison to TravisCI which has 8k stars & 756 forks. However, these numbers alone don’t imply which CI/CD tool is more suitable for your upcoming or existing project. Jenkins is an open-source & Travis CI is free for open-source projects.
