Thanks for this @Ottovsky !

For people trying to build this locally, this worked for me (11 November 2021):

• dump the above gist contents into a Dockerfile
• Then run docker build -t gitlab-runner-armv7 --build-arg GIT_LFS_VERSION=3.0.2 --build-arg GITLAB_RUNNER_VERSION=12.10.1 --build-arg DOCKER_MACHINE_VERSION=0.16.2 --build-arg TINI_VERSION=0.19.0 .
• verify it's working: docker run --rm -it gitlab-runner-armv7 --help

For runner version 14.7.1, use Docker file as so (the entrypoint file location moved, rest is the same as above):

Build with a script like so:

#!/bin/bash
RUNNER_VERSION="14.7.1"
docker build -f Dockerfile-$RUNNER_VERSION -t gitlab-runner-armv7 --build-arg GIT_LFS_VERSION=3.0.2 --build-arg GITLAB_RUNNER_VERSION=$RUNNER_VERSION --build-arg DOCKER_MACHINE_VERSION=0.16.2 --build-arg TINI_VERSION=0.19.0 .

And run/upgrade with script like:

#!/bin/bash
RUNNER_NAME=gitlab-runner
docker container stop $RUNNER_NAME
docker container rm $RUNNER_NAME
docker run -d --name $RUNNER_NAME --restart always \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v gitlab-runner-config:/etc/gitlab-runner \
    gitlab-runner-armv7:latest

Thank you for the update! It has been a while when I was playing with gitlab-runners on arm :)

cool Thing, thanks! 👍 :)

thanks @demaniak ! helped me get my Pies doing some work!
