issues with Dockerfile upgrade to jdk:17

[jonathanstrong]

encountered this error message from running $ docker build .:

Step 10/13 : RUN apt-get update && apt-get -y upgrade && apt-get install -y git
 ---> Running in 107a7a75fb08
/bin/sh: apt-get: command not found

It's confusing because the image it was using before (openjdk:11) did that step just fine, I guess they changed it.

I found another image, openjdk:slim-bullseye that works. "bullseye" is debian release code name. not sure if "slim" is worth much vs the fat one but it was the first one I got to work.

Initially I tried to do openjdk:17-alpine but that had a lot of differences (apk vs apt-get, need to install openssh, different command line options for useradd/groupadd and I abandoned that effort).
