Docker image for shinyproxy ment to be used with kubernetes.
Most of the work is just picked from this GitHub repository. This container is to enable customization in more general way.
Proxy env vars are considered and may just be injected using kubernetes env vars. See Example.
application.yml is the name of the ShinyProxy configuration file. This file has to be injected using a configmap. AS shinyproxy expects the config to be in the same directory as the shinyproxy.jar we do create a symbolic link to the subfolder ./config/application.yml so the config file can be mounted to this directory.
Like in the example repo from above, this implementation requires a sidecar to proxy the kubernetes requests.
