Gitlab - Google compute engine Continuous delivery - swift3

Question

What I am trying to do is to enable Continuous delivery from GitLab to my compute engine on Google Cloude. I have Ubuntu 16.04 TSL running over there. I did install all components needed to run my project like: Swift, vapor, nginx.
I have manage to install Gitlab runner as well and created a runner whcihc is accessible from my gitlab repo. Everytime I do push on master the runner triggers. What happen is a failure due to:
could not create leading directories of '/home/gitlab-runner/builds/2bbbbbd/0/Server/Packages/vapor.git': Permission denied
If I change the permissions to chmod -R 777 It will hange on running for build stage visible on gitlab pipeline.
I did something like:
sudo chown -R gitlab-runner:gitlab-runner /home/gitlab-runner/builds
sudo chown -R gitlab-runner:gitlab-runner /home/gitlab-runner/cache
but this haven't help, the error is same Permission denied
Below you have my .gitlab-ci.yml
before_script:
- swift --version
stages:
- build
- deploy
job_build:
stage: build
before_script:
- vapor clean
script:
- vapor build --release
only:
- master
job_run_app:
stage: deploy
script:
- echo "Deploy a API"
- vapor run --name=App --env=production
environment:
name: production
job_run_frontend:
stage: deploy
script:
- echo "Deploy a Frontend"
- vapor run --name=Frontend --env=production
environment:
name: production
But that haven't pass to next stage eg. deploy. I had waited more then 14h for that but with out result.
And... I have few more questions:
Gitlab runner creates builds under location /home/gitlab-runner/builds/ in this location every new job have own folder. for eg. /home/gitlab-runner/builds/2bbbbbd/ in which is my project and the commands are executed. So what happens when the first one is running and I do deploy new version? the ports are blocked by the first instance and so on?
If I want to enable supervisor how do I do that with this when every time I deploy folder is different?
Can anyone explain or show me or point me to tutorial how do Continuous deployment with out docker?

How to start a service using GitLab runner
Thanks to long deep search I finally found an answer! The full article can be found above.
Briefly GitLab CI documentation recommends using dpl for deployment. Gitlab runner run test and process should end. The runner is designed to kill all created processes after finishing each build. The GitLab runner is unable to perform operations outside the catalogue.
