Running 4.15 on raspberry pi within docker container
You need Java 11.
Love your short and prompt responses! The part about needing Java 11 was somewhat obvious based on the missing package name. I am hoping though that someone has pointers/instructions on an alternative path to get Traccar/jre-11 going on a docker container running on a raspberry pi 4.
A related question (if you know this off the top of your head) - which was the last version of Traccar that ran on java 8? I could go through all of the changelogs but if there a quick answer to this it will save me the time.
Thanks for a great product!

The easiest option is to check grade file history.
After a bit of googling and experimenting ended up with this working version of Dockerfile to get you up and running on a raspberry pi docker container.

I am using this Dockerfile: https://github.com/traccar/traccar-docker/blob/master/Dockerfile.alpine
Building docker image fails since openjdk11-jre-headless package is not available for alpine linux on rapberry pi.
Can someone point me to other options to get this going. I tried with jdk8 but I ran into errors about a Class being at higher version than supported.
Thanks.
