Script

• script: it is required and it can be a single command or an array of commands
• before_script and after_script are both optional, but if they exists they must be arrays (even if there is only one element)
• You can have before_script and after_script as a main-key in the YAML file.
• A job that does not have before_script will inherit the central before_script. Same with after_script.

anything:
  image: busybox:latest

  # script is required and can be a single value or an array
  script: echo The script

  # after_script is optional but must be an array
  after_script:
    - echo After script
  # before_script is optional but must be an array
  before_script:
    - echo Before script
