cppbuild failes tests when building docker container targeting ubuntu 22.04

[rafalpiotrowski]

Hi,
I am trying to build docker container from latest version of aeron repo and I am getting few failed tests.

`
585.7 The following tests FAILED:

585.7 91 - rejectImageTestW (Failed)

585.7 102 - udp_channel_test (Failed)

585.7 116 - name_resolver_test (SEGFAULT)

585.7 124 - c_local_addresses_test (Failed)

585.7 Errors while running CTest
`

Here is the Dockerfile I use to do it

`
ARG VERSION="22.04"
FROM ubuntu:${VERSION} as builder

RUN cppbuild/cppbuild --c-warnings-as-errors --cxx-warnings-as-errors --package

FROM scratch AS essentials-artifacts
COPY --from=essentials-build /opt/aeron/cppbuild/Release/*.tar.gz /
`

command to run it is
docker build cppbuild/ubuntu --shm-size=256m

note that I have increase the shm size 245MB since witht he default more test were failing indicating low storage issue.

Attached is the output showing the error in details.

Hi Rafal,

The failing tests are tests that bind to ipv6 loopback interface (::1). The default behavior for docker is to enable ipv6 loopback except if the kernel does not have ipv6 support or ipv6 is disabled. moby/moby#47062.

If for some reason ipv6 is disabled for new namespaces only, you can use --network host (as argument to docker build or RUN in dockerfile) to use your host's network namespace, if ipv6 is enabled on your host.
Alternatively, you can just skip tests with the flag --no-unit-tests as an argument to the cppbuild script.

We typically run docker build with 1G of shm size.

thank you! will try this out
