About

An Ansible Playbook which can be used for Building a docker image, Pushing and to Test the image with a docker container. Advantage of using this playbook is if there is any new commits on Git repo, the playbook will initiate the above tasks. The Playbook is designed in such a way,that the build operations are done on one server and Testing operations on another server.

Outline

• main.yml

  • Setting Fact Values.
  • Calling tasks, Build and Test based on the condition.

• build.yml

  • Fetching new codes from Git.
  • Creating Docker Image.
  • Taging and Pushing Image to Docker Registry.

• test.yml

  • Pull the latest image from the Docker registry, if only there is a new update.
  • Create Docker container with the new image, else task will get skiped.

Prerequisites

• The git repo must have Docker file and the code section( if needed).
• Idea about configuring Tasks on Jenkins.
• Add Webhook on Git.
