I’ve just updated our Linux images to use ‘default’ to avoid issues with the upcoming image deprecations. Now my tests fail on arm64, but not amd64.
When I connect to the tests I see the following behaviour which suggests that one is running cgroup1 and the other cgroup2.
On amd64
$ docker run --rm -it --memory=512Mb ubuntu:22.04 bash
root@95e8a477bb2c:/# cat /sys/fs/cgroup/cpu.max
max 100000
On arm64
$ docker run --rm -it --memory=512Mb ubuntu:22.04 bash
root@f5bdb9945390:/# cat /sys/fs/cgroup/cpu.max
cat: /sys/fs/cgroup/cpu.max: No such file or directory
I see the same behaviour with 20.04 as well. Is this an issue with the new default images, or with the ubuntu images?
This worked fine with ubuntu-2204:2022.07.1 so I thought I’d check here.
