There's a simple docker image that contains pre-configured nginx proxy for prometheus, with a Basic Authentication with admin/admin credentials: jotak/nginx-basicauth-sidecar. It listens on 8080 and redirect to 9090 (where prometheus is expected to be). To rebuild the image, take a look at https://github.com/eicnix/sidecar-proxy-example

Steps

• Modify your prometheus deployment and add this container description:

        - image: jotak/nginx-basicauth-sidecar
 imagePullPolicy: IfNotPresent

One issue I'm currently facing in Go (looks like it's not an isolated problem) is the lack of meta-programming.

I want to create a simple function that turns any slice into a map, being provided a key-getter function.

I wish I could write something like this:

type KeySupplier<T> func(obj T) string

func Index<T>(arr []T, keySupplier KeySupplier<T>) map[string]T {
