-# This variable holds all commands that are needed to be able to connect to the target server via SSH.
-# For this you need to define two variables in the GitLab CI/CD variables:
-#   - SSH_PRIVATE_KEY: The contents of the SSH private key file. The public key must be authorized on the target server.
-#   - DEPLOYMENT_SERVER: Just the hostname of the target server (e.g. shopware.com, don't include schema or paths)
