SDLC CICD and Jenkins-GitLab Integration

SDLC and CICD Architecture

The Continuous Integration Pipeline is the background we wanted to do Jenkins-GitLab Integration. We wanted to achieve a goal that:

• as soon as dev merges a code to a branch, we can quickly run a pipeline as below to provide him a CI result:
  • pull dev’s latest code
  • build and deploy
  • run test
  • update the GitLab pipeline

Jenkins-GitLab Integration

Architecture

Jenkins-GitLab integration https://docs.gitlab.com/ee/integration/jenkins.html setup:

• GitLab can trigger Jenkins builds
  • Two ways. 
    • Jenkins CI Integration (recommended) 

• Webhook

• Jenkins can update back GitLab pipeline statusHow to setup a Jenkins

Demo

Freestyle – publish build status to GitLab 

Setup a job using post build

Pipeline – updateGitlabCommitStatus

Screenshoot

Pipeline

Setup GitLab connection for the pipeline

Setup GitLab event build triggers for the pipeline
