[Feature]: Docker: Add HEALTHCHECK command about oauth2-proxy HOT 4 OPEN

I avoid having shells, downloaders, or package managers in prod images for security purposes. So a health check option, as initially proposed, would make sense, imho.

I've just realised that the alpine images — as contrasted the distroless ones — can be fairly easily extended with e.g.:

FROM quay.io/oauth2-proxy/oauth2-proxy:v7.6.0-alpine

RUN apk --no-cache add curl
HEALTHCHECK --interval=30s --timeout=5s CMD ["/usr/bin/curl", "-f", "http://localhost/oauth2/ready"]

This meets our immediate needs, but maybe this feature request is still valid for out-of-the-box HEALTHCHECK support.

Hi,
The alpine image has wget , have you tried to use it for healthcheck?

Yes, I did end up using the alpine image. It's enough for our purposes, but it might still be helpful to have it available as part of the base Docker image so that folks don't need to extend it.
