How to do a simple pull with gitlab-ci.yml?

Question

What is the correct form to do a git pull in my server project everytime I do a git push to my gitlab repository from my local project?

This is my gitlab-ci.yml:

stages:
  - test
  - deploy

test:
  stage: test
  only:
    - develop
    - production
  script:
    - git checkout develop
    - git pull

step-deploy-prod:
  stage: deploy
  only:
    - production
  script:
    - git checkout production
    - git pull
  environment: production
  when: manual

And this are the messages from the Gitlab CI/CD Jobs:

The current behavior observed is the expected one, as all the commands being run by gitlab is inside its own environment and not on your servers.

To achieve the expected behaviour:

Understand that you already have develop/production codebase inside your environment prior to git checkout command, to confirm it you may include ls -al before git checkout. Therefore, git checkout and git pull are redundant, as only configuration makes sure that your pipeline only runs for those specific branches.
You have to do one of the following:
1. Sync your files from current gitlab environment to your digitalocean server (Using rsync)
2. Remotely run your commands git checkout and git pull from gitlab pipeline on your digitalocean server (Reference1 and Reference2).

1 is recommended for codebases that are required to be built before deployment. Yet for your simple usecase 2 is sufficient.
