Getting different architectures in slim images

[jokarl]

Slim images give the wrong architecture, see below:

pi@raspberrypi:~ $ docker run -it arm32v7/openjdk:8-jre-slim-stretch /bin/sh
# dpkg --print-architecture
armel

pi@raspberrypi:~ $ docker run -it arm32v7/openjdk:8-jre-stretch /bin/sh
# dpkg --print-architecture
armhf

pi@raspberrypi:~ $ docker run -it arm32v7/openjdk:8-jdk-slim /bin/sh
# dpkg --print-architecture
armel

pi@raspberrypi:~ $ dpkg --print-architecture
armhf

Looks like the 8 variants have been failing to build on arm32v7 for a while: 😞

I noticed that too when I built my own image based on the arm32v7 debian stretch image and then trying to install it the same way as is done in openjdks Dockerfile. Doesn't seem like an error with this image then?

[tianon]

Yeah, there's something quirky going on with the Debian package we're pulling from, unfortunately (and it seems to not affect amd64 for whatever reason).

[jokarl]

I did a clean install of the armhf openjdk on a fresh raspian install earlier today without any problems. I can't get any more specifics until Monday unfortunately, but I'll update with some more details then.

[jokarl]

So from a fresh raspbian install on a raspberry, I ran the following:

I don't know if this might be of any help.

None of the official images are based on Raspbian, so unfortunately not.
