Sun, 20 Aug 2023 01:35:07 +0200

UPDATE 2023-08-28

The bug is now fixed, you only need to update to the newest version of docker on affected systems!

ORIGINAL TEXT

Yesterday night I have tried to build a container running a python-application as non-root user and I stumbled onto a bug currently tracked as #2029523.

Example Dockerfile:

FROM alpine:latest

ENV BUSTCACHE=2

RUN adduser -S -D -h /home/test test && ls -al /home/test

WORKDIR /home/test

COPY --chown=test:nogroup foo.txt foo.txt

USER test

RUN whoami && ls -al . && touch bar.txt

The file foo.txt is a plain text file containing only the single word ‘bar’.

Installing JAVA JDK/JRE on Debian/Ubuntu with ease

I recently commenced the third installation of JAVA on one of my Debian-Boxes and couldn’t remember any of the exact commands, had to google again, ended up with 8 open tabs all saying something different and so wrote this small bash script to set up all necessary alternatives with “update-alternatives” automatically.

Please note that there has to be either icedtea or openjdk installed to make all parts of this script work.
