Run gitlab-ci-local in Docker on Windows

[Winand]

I've tried to run GCL in WSL and natively but had different problems especially with paths conversion between Windows and Linux.

Finally I started to use GCL inside Docker and it's quite usable.

Dockerfile:

FROM almalinux:10
RUN dnf install -y gzip rsync git-core 'dnf-command(config-manager)' && \
    dnf config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo && \
    dnf install -y docker-ce-cli && \
    dnf clean all
RUN curl -L https://github.com/firecow/gitlab-ci-local/releases/latest/download/linux.gz | \
        gunzip -c > /usr/local/bin/gitlab-ci-local && \
    chmod +x /usr/local/bin/gitlab-ci-local
COPY start.sh /
WORKDIR /ci
ENTRYPOINT ["/start.sh"]

start.sh script:

#!/bin/bash
set -e

# Use mounted ssh keys from host
cp -r /tmp/.ssh /root
chmod -R 600 /root/.ssh

# Fix git error "detected dubious ownership in repository", caused by wrong
# ownership of .git folder (not root user).
# See https://github.com/firecow/gitlab-ci-local/blob/4.61.0/src/git-data.ts
git config --global --add safe.directory /ci

# --mount-cache uses Docker volumes which improves performance
exec gitlab-ci-local --shell-executor-no-image=false \
     --default-image=${OptionalCustomDefaultImage} \
     --mount-cache "$@"

Add the following function to profile.ps1 to be able to run gitlab-ci-local command in PowerShell.

function gitlab-ci-local {
    docker run --rm -it `
        -v /var/run/docker.sock:/var/run/docker.sock -v "$(pwd):/ci" `
        -v "$HOME/.gitlab-ci-local:/root/.gitlab-ci-local" `
        -v "$HOME/.ssh:/tmp/.ssh:ro" `
        gitlab-ci-local:latest @args
}

I just run gitlab-ci-local from the WSL debian terminal and have never experienced any issues with it.

I think I had an issue with .git folder ownership in WSL (like in #1619), because in my Notion I wrote down that .gitignore settings were ignored. So maybe simple chown call may fix that problem.
