.gitlab-ci.yml

# PLEASE NOTE
# This CI recipe will work provided that:
# - a variable is set named GIT_REMOTE
#   contaning the full path to the repository
#   that I want to deploy to
#   example: "git@github.com:username/projectname.git"
# - (please note) in case of multiple destinations
#   a set of multiple variables is required, example:
#   GIT_REMOTE_GITHUB: "git@github.com:username/projectname.git"
#   GIT_REMOTE_GITLAB: "git@gitlab.com:username/projectname.git"
# - a variable is set named SSH_PRIVATE_KEY
#   containing the private part of a key
#   that enables SSH access to the repository
# - CI pipelines preferences contain
#   "git clone" instead of "git fetch" setting
image: bluewind/git
variables:
  GIT_SUBMODULE_STRATEGY: recursive
  GIT_SUBMODULE_NAME: remark-slides

# prepare SSH accesso to remote
  - mkdir -p ~/.ssh
  - echo "$SSH_PRIVATE_KEY" | tr -d '\r' > ~/.ssh/id_rsa
  - chmod 600 ~/.ssh/id_rsa
  # disable host key checking (NOTE: makes you susceptible to man-in-the-middle attacks)
  # WARNING: use only in docker container, if you use it with shell you will overwrite your user's ssh config
  - 'echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config'
