1. Why do you build and publish images via registry.gitlab.com/aelve/codesearch/ci-test-env image?
2. Also it seems to me that connecting to the server via ssh will not work. Please check it and If that doesn't work then use this image: https://github.com/kroniak/alpine-ssh-client

Also use a snake_case naming notation to all tasks instead kebab-case. E.g.: staging-deploy-to-swarm to staging_deploy_to_swarm.
