orca hangs when generating graphs behind a proxy server

[Pell17]

I'm using the docker image and need to use a proxy server to access the Internet. When executing the image with the --plot parameter, it hangs at the place where I hit ^C below.

^C2021-07-28 19:05:16 [ERROR] Trapped CTRL-C, trying to exit gracefully ...

The reason is that it's creating a pod with a plotly-orca container from quay.io/plotly/orca. This image is trying to download plotly from the Internet, but fails as it doesn't use the proxy server.
I created a workaround locally by adding the corresponding environment variables to the pod spec in knb:

        cat <<-EOF | kubectl apply $NAMESPACEOPT -f - >/dev/null|| fatal "Cannot create pod $POD_NAME"
        apiVersion: v1
        kind: Pod
        metadata:
          labels:
            app: $POD_NAME
          name: $POD_NAME
        spec:
          containers:
          - name: plotly-orca
            image: quay.io/plotly/orca
            env:
              - name: HTTP_PROXY
                value: "http://my-proxy:8080"
              - name: HTTPS_PROXY
                value: "http://my-proxy:8080"
          restartPolicy: Never
        EOF

I haven't checked if orca uses http or https so I added both. Naturally there should be a better solution, e.g. a proxy option or allowing the http(s)_proxy variables to be passed in with "-e" to docker run and inserting them into the pod spec if given.
Thanks for a great tool!
