First Gitlab pipeline

Gitlab pipeline scripts are written and stored in .gitlab-ci.yaml file and kept in root of the project repository

stages:
  - build
  - test

compiling-java-code:
  stage: build
  script:
    - echo "Running in compiling-java-code job"

compiling-python-code:
  stage: build
  script:
    - echo "Running in compiling-python-code job"

testing-code:
  stage: test
  script:
    - echo "Running in testing-code job"

• stages section is a collection of stage in a sequential order. stages section is just used to define the order for stage
• Each stage can have one or more jobs.
• Multiple jobs in a stage can run in parallel, here the build stage contains two jobs compiling-java-code and compiling-python-code, which can run in parallel
• Once all the jobs in build stage gets successeded, it will execute the next stage test which contains a job testing-code
