How do all the automation tools work together in a CICD flow?

Share:

In a CICD pipeline, everything gets automated for seamless delivery. However, this flow may vary from organization to organization as per the requirement.

A generic DevOps flow would be:

  • Developers develop the code send this code to the Git repository and any changes made in the code is committed to this Repository.
  • Jenkins pulls this code from the repository using the Git plugin and build it using tools like Ant or Maven.
  • Unit testing is performed using JUnit kind of framework. (JUnit plugin available in Jenkins).
  • Once, the application is packaged in an executable file, it is pushed to an artifactory like JFrog and then, a Docker image comprising of the application (pulled from artifactory) and all its dependencies is created.
  • Configuration management tools like Ansible deploy this image across environments with the environment specific configuration settings.
  • Once it reaches testing environment, Selenium is used to run the automated test cases.

  • review rating 4  Both trainers (Ravi and Naresh) were excellent in their approach. Session was less of a theory and more of a practical. And even the theory part was quite interesting. A bit issue with the volume of information which I had received in just a span of 2-3 days - it seemed a bit over-loaded. But overall, it has given me a great platform to take it forward from here!

  • review rating 4  It was good session, I left my training room with basic knowledge on all the tools. Tutors have great knowledge and experience on the tools. But three days is not enough time.
