Deploy docker to docker-machine on host

GitLab CI/CD
1

I have gitlab-runner running in a docker container.

I have a build step building my application and a Dockerfile in the ‘Docker’ folder, followed by the following deploy step:

deploy:
  image: docker:latest
  stage: deploy
  script:
    - 'cd Docker'
    - 'pwd'
    - 'docker build -t xxx/myapp .'

However, the last step fails with:

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Is it possible to build, deploy and run a docker image on the host (or other remote docker), or will I need to install the runner locally on the docker host to do so?

I found out I was missing the --docker-privileged flag.

But now I need to solve being able to copy files from one step to another. I can see that this can be accomplished by artifacts, so I tried adding the ‘output’ folder from my dotnet build. However, when I do, I get the following error:

Docker/output/*.*: found 132 matching files

I tried with a single empty .txt file, and that worked fine.

Any ideas behind this error?

How big is the artifact?

5

334MB in total. I’ve increased the allowed limit to 1000MB though.

And if you would fake stuff with a large file like that? So you can at least rule any upload issues.

Certainly something I can try…
