Description
As the title suggests there seems to be an issue with apk/wget when using alpine:3.13.0 and higher. I have a simple Dockerfile:
FROM alpine:3.15.0
ENV http_proxy http://igwng.m086:3128
ENV https_proxy http://igwng.m086:3128
RUN http_proxy=http://igwng.m086:3128 apk add wget
When you build this Dockerfile docker build -f Dockerfile .

However, downgrading to alpine:3.12.0 works:

I've done a couple of tests regarding proxy/restarting Docker and pretty much anything else you could find on the web, nothing helped. But maybe this is a DNS Issue:
