I am trying to build a simple container for Raspberry Pi model 2 that would run the Nginx server in the reverse proxy mode. I use a private project in the Gitlab.com to store the source code as well as the docker image registry and I would like to automate the build process using the Gitlab CI pipeline.
I can successfully manually build and push the docker image from my windows command line (Docker for Windows is installed), but I am struggling with the Gitlab pipeline integration:
when GitLab Runner is registered under Docker for Windows in shell mode, it builds, but fails to push the image to the registry. This would be Gitlab related probably.
I tried to run the GitLab Runner under Docker installed in Synology NAS, but no luck to set it connecting to the GitLab successfully to even start building.
I installed RancherOS into a virtual machine under Hyper-V and run and registered the GitLab Runner from this, but this fails with error:
Step 4 : RUN apt-get update && apt-get -qy install curl ca-certificates nginx
—> Running in e44b8da07ed5
standard_init_linux.go:175: exec user process caused “exec format error”
The command ‘/bin/sh -c apt-get update && apt-get -qy install curl ca-certificates nginx’ returned a non-zero code: 1
ln: failed to create symbolic link ‘/sys/fs/cgroup/systemd/name=systemd’: Operation not permitted
Is there any best practice to build the resin RPi images in GitLab?
# Enable systemd ENV INITSYSTEM on ENTRYPOINT  # Install Nginx RUN apt-get update && apt-get -qy install curl ca-certificates nginx # Configure Nginx RUN rm /etc/nginx/nginx.conf COPY nginx.conf /etc/nginx/nginx.conf EXPOSE 80 # Configure Nginx logging RUN ln -sf /dev/stdout /var/log/nginx/access.log RUN ln -sf /dev/stderr /var/log/nginx/error.log # Run Nginx CMD ["/usr/sbin/nginx"]
My .gitlab_ci.yml just runs:
docker build -t $FULL_IMAGE_NAME .
The Gitlab Runner registration under RancherOS in option 3) higher was done this way:
sudo docker run -d --name gitlab-runner --restart unless-stopped --privileged=true -v /var/run/docker.sock:/var/run/docker.sock gitlab/gitlab-runner:latest sudo docker exec -it gitlab-runner gitlab-runner register --non-interactive --url "https://gitlab.com/" --registration-token XXXXXXXXXXXXX --description "My RancherOS Gitlab dind runner" --executor "docker" --docker-image gitlab/dind:latest --docker-privileged=true --tag-list "docker" --run-untagged --locked="false"
Thans in advance for your support.
