How to run Robusta KRR in docker?

[bab5470]

If there is documentation for this I'm not finding it (kindly point me in the right direction if I've overlooked something).

I've cloned the KRR repo and run:
docker build -t krr .
docker run -d --name krr -v /home/myuser/.kube/krr.yml:/root/.kube/config -e KRR_KUBE_CONFIG=/root/.kube/config -e KRR_KRR_PORT=8080 localhost/krr:latest

I am getting:

[16:39:16] ERROR    Could not load kubernetes configuration:       runner.py:326
                    Service host/port is not set.

                    --kubeconfig flags.

How do I specify the service host/port and the kubeconfig files? Is there an example somewhere?

I use this with an EKS cluster and SSO configured, successfully (though my mounts are a bit broad):

docker run --rm --volume "${KUBECONFIG}:/root/.kube/config:ro" --volume "${HOME}/.aws:/root/.aws:ro" -e KUBECONFIG=/root/.kube/config localhost/krr

However, I build a custom image to include the awscli in the image:

FROM us-central1-docker.pkg.dev/genuine-flight-317411/devel/krr:v1.18.0
RUN apt-get update && \
    apt-get -y install awscli

[nathanmcgarvey-modopayments]

Oh, and if you want options, you have to specify the full command as the base image has no entrypoint:

docker run --rm -t --volume "${KUBECONFIG}:/root/.kube/config:ro" --volume "${HOME}/.aws:/root/.aws:ro" -e KUBECONFIG=/root/.kube/config -e "TERM=xterm-256color" localhost/krr python krr.py simple --allow-hpa --width 300

Note that I also ensured it has colorized output and a much wider than default width for docker terminal stuff.

None of these are working for me:

docker run --rm --volume "${KUBECONFIG}:/root/.kube/config:ro" -e KUBECONFIG=/root/.kube/config localhost/krr
