It might be because adoptopenjdk/openjdk11:jre-11.0.10_9-alpine now fetches packages from https://dl-cdn.alpinelinux.org/alpine/v3.13/main/x86_64/APKINDEX.tar.gz:

I'm not sure why since the Dockerfile of adoptopenjdk/openjdk11:jre-11.0.10_9-alpine indicates FROM alpine:3.12... I also cannot reproduce this issue locally.

Maybe a Docker bug? I will try to upgrade Docker, I'm using v20.10.3 on my machine.

After a docker system prune -a I get the same result on my machine, running smoke tests...

We might need to downgrade to adoptopenjdk/openjdk11:jre-11.0.9.1_1-alpine:

$ docker run -it adoptopenjdk/openjdk11:jre-11.0.9.1_1-alpine
