# This script will run create a virtual provider
# and run tests on it.
#
# This script is triggered by .gitlab-ci.yml
#
# It depends on:
#   * leap_platform: in ../..
#   * test provider: in provider/
#   * leap-platform-test: installed in path
#   * AWS credentials as environment variables:
#     * `AWS_ACCESS_KEY`
#     * `AWS_SECRET_KEY`
#   * ssh private key used to login to remove vm
#     * `SSH_PRIVATE_KEY`
#
# Todo:
#   - Running locally works fine, now use it in gitlab CI ( which ssh-key ? create cloud.json from env vars )
#   - Speed up vm boot if possible ( right now 3-4mins )

# exit if any commands returns non-zero status
