Public bug reported:
I wanted to try the new Ubuntu 24.04 Noble Numbat based .NET docker
image and updated the base docker image in our CI pipeline to
mcr.microsoft.com/dotnet/sdk:8.0-noble. However, it results in an out-
of-memory exception. Based on my investigation, the exception occurs
specifically when the update-ca-certificates command is executed. I can
also repro the issue with ubuntu:noble image which means it's not
specific to .NET docker images. It works fine with Jammy, by the way.
The problem likely lies with the Noble base image rather than the .NET
image. I'm not sure what changes were made between Jammy and Noble, but
it appears that updating certificates consumes a lot of memory in Noble.
I adjusted some memory settings in our GitLab runner, but it didn't
resolve the issue. I attached all Gitlab Runner shell logs for .NET 8
Jammy, .NET 8 Noble and Ubuntu Noble images.
