CODE EXAMPLE FOR SHELL

gitlab ci credentials store

before_script:
  ##
  ## Install ssh-agent if not already installed, it is required by Docker.
  ## (change apt-get to yum if you use an RPM-based image)
  ##
  - 'command -v ssh-agent >/dev/null || ( apt-get update -y && apt-get install openssh-client -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.
  ## https://gitlab.com/gitlab-examples/ssh-private-key/issues/1#note_48526556
  ##
  - echo "$SSH_PRIVATE_KEY" | tr -d '
' | ssh-add -

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

  ##
  ## Optionally, if you will be using any Git commands, set the user name and
  ## and email.
  ##
  # - git config --global user.email "user@example.com"
  # - git config --global user.name "User name"
