before_script:
  - apt-get update -qq
  - apt-get install -qq git
  ##
  ## Install ssh-agent if not already installed, it is required by Docker.
  ## (change apt-get to yum if you use an RPM-based image)
  ##
  - 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client git -y )'

  ##
  ## Run ssh-agent (inside the build environment)
  ##
  - eval $(ssh-agent -s)

  ##
  ## Add the SSH key stored in SSH_PRIVATE_KEY variable to the agent store
  ## We're using tr to fix line endings which makes ed25519 keys work
  ## without extra base64 encoding.

  ##
  - echo "$SSH_PRIVATE_KEY" | tr -d '\r' | ssh-add - > /dev/null

  ##
  ## Create the SSH directory and give it the right permissions
  ##
  - mkdir -p ~/.ssh
  - chmod 700 ~/.ssh

  ##
  ## Use ssh-keyscan to scan the keys of your private server. Replace gitlab.com
  ## with your own domain name. You can copy and repeat that command if you have
  ## more than one server to connect to.

  - ssh-keyscan gitlab.com >> ~/.ssh/known_hosts
  - chmod 644 ~/.ssh/known_hosts
  - '[[ -f /.dockerenv ]] && echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config'
