Setting up a Registry Mirror

[gleaming silo]

Hey everyone!
I'm trying to find a way to set-up a registry mirror, similar to https://docs.docker.com/build/buildkit/configure/#registry-mirror

Is there a way to do this in Dagger?
Setting up the configuration files for Buildkit doesn't seem to work unfortunately.

if you want to customize the buildkit.toml in your Dagger engine, you can do so by overriding the /etc/dagger/engine.toml inside of it. Here's an example:

# Add your buildkit config here
cat <<EOF > engine.toml
debug = true
EOF

MAIN_RELEASE="v0.5.1"
container_name="dagger-engine-$(docker inspect registry.dagger.io/engine:$MAIN_RELEASE -f '{{index .RepoDigests 0}}' | cut -d ':' -f2 | cut -c -16)"

docker run --privileged -d --name $container_name -v $(pwd)/engine.toml:/etc/dagger/engine.toml registry.dagger.io/engine:$MAIN_RELEASE

the container_name can be anything as long as the prefix is dagger-engine-

That worked! I spent waaay too much time on this 😄

I ended up spinning up a container and using _EXPERIMENTAL_DAGGER_RUNNER_HOST=docker-container://dagger-engine-jenkins instead, but the solution (mount /etc/dagger/engine.toml) is the same

Thank you so much!
