Deploy something with Gitlab

10 May 2021

Basicly, when you want to “deploy” something via Gitlab CI/CD, that just mean building something inside a docker container and Rsync the result to the production server.
Continuous Integration” and “Continuous Deployment” are just fancy word that mean you put your shit online. It’s not magic, it’s automated FTP with Git as the source.

First create SSH_PRIVATE_KEY with a ssh private key that can access the server.

ssh-keygen -t rsa -b 4096 -C ""

Don’t use the passphrase, otherwise, the automatique login wont work.
You need to add the public key to a file named ~/.ssh/authorized_keys and chmod 0644 ~/.ssh/authorized_keys that file.

Now we just need to add this ssh key to the gitlab-ci that will Rsync what ever file you want to put on the server

  stage: deploy
  image: my_image
    - apt-get update
    - apt-get install -qq rsync
    - 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'
    - eval $(ssh-agent -s)
    - ssh-add <(echo "$SSH_PRIVATE_KEY")- mkdir -p ~/.ssh
    - '[[ -f /.dockerenv ]] && echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config'
    - rsync -av public/js/ myuser@mydomain:public_html/public/js
    - master
