Kash BDP Pipeline

What is it ?

BDP stands for Build Deploy Promote.
It is Build and Deployment Pipeline as Code. This is a set of three building blocks made up of declearative jenkinsfile,when combined other components - test suite,vulnerability scanning,etc., will become a complete CI/CD system of your choice. You can use these block for your application and combine with your test suites(unit tests, regression tests,stress tests) to build your own CI/CD. Three building blocks are namely build, deploy and promote. This pipeline can be used to dockerize the application and deploy in kubernetes platform provided by various cloud providers - gcp,aws.(other clouds coming soon)

Building blocks

These building blocks are primitive, each serves a single purpose.

Build - code check out, building the artifact, dockerize and push the docker image to the container registry.

Deploy - Deploy the application as helm chart

Promote - promote the docker to higher environment by adding new docker tag.

These building blocks can be cascaded and combined with each other as per the need and can form a complete continuous integration and continous deployment pipeline. Build, deploy and promote blocks are build as jenkins files.

Feature

  • Ability to support parallel execution of the build job, deployment job, image promotion job.Execution of one job should not affect other job
  • Jenkins configuration are passed to building block as files.This results in minimum changes in jenkins job configuration.
  • Cleanup of unwanted Docker image - will be discussing in detail separately.
  • mechanisms by which some special docker images that are excluded from Clean as mention above.These special images are called as Static images.
  • Ability to have separate configuration from application for each environment and region as recommended by 12factor
  • Ability to pull and push docker images to different different public cloud container registries.
  • Supports code checkout of over both http and ssh.
