Improve MAC docs for MCS and docker for BuildKit usage
See commits for details. The first one is for fixing an omission in
!3281, the second to clarify docker build usage.
Closes: #973
The Dockerfiles are reused for building on different architectures
(amd64/arm64). They differ, though, on some steps for downloading or
installing platform-specific utilities.
This is handled automatically when using BuildKit, which is the default
in docker versions v23.0+. Older docker versions require some special
settings. Explain this in the README.
Closes: #973
This updates all images in the CI to Ubuntu 22. It also updates
corresponding documentation. Remove python(2) from the image, as it is
not needed. Update documentation.
It seems that the gcc coming in Ubuntu 22 does not like
stack-protector-strong, so remove it as well.
Since we compile Flexric, which does not support Ubuntu 22's default
gcc-11 (it hits a compile bug), switch to gcc-12 manually.
Since we update the compiler, we also need to be careful to use the right
address sanitizer version (which is bundled with the compiler version).
To avoid a reinstallation of the wrong asan version in target images, we
modify Ubuntu 22 targets to copy libasan from the base image. This is necessary
since we use update-alternative in the base image, but we don't want to
install compilers in the target images to use update-alternatives to
install the right asan version... This should be undone when switching
to Ubuntu 24 in the future, as it will have a newer default gcc version,
such that we don't need to update the compile in the first place.
Upgrade libpython in lteUE for U22 upgrade to make it compatible with
UHD.
* Dockerfile argument is now a generic BUILD_OPTION for any build_oai available option
* docker-compose files are only modified at deployment time. Not needed for undeployment
* fixes for oai-nr-cuup
* cleaner section for the private registry push
