Necessary permissions in docker using a rootless user for dotnet-* tools #2102
Description
Hello,
I'm using the dotnet-dump / dotnet-trace within a docker container, engine running in WSL2, using a rootless user.
dotnet-dump
In my docker file, I added CAP_SYS_PTRACE capabilities to createdump using setcap CAP_SYS_PTRACE=+eip $(find /usr/share -name createdump)
I also start my container with --cap-add=SYS_PTRACE
Once I did that I was able to get passed the error Core dump generation FAILED 0x80004005 due to PTrace(ATTACH, 1) FAILED Operation not permitted
However now I'm getting the error
/usr/share/dotnet/shared/Microsoft.NETCore.App/5.0.4/createdump: error while loading shared libraries: libmscordaccore.so: cannot open shared object file: No such file or directory
chowing recursively the directory /usr/share/dotnet/shared/Microsoft.NETCore.App to a group where my user is in also has no impact.
is root absolutely necessary to create dumps? If this is the case, is running a side-car container my only option to be able to generate dumps if my main application container runs under a rootless user?
dotnet-trace
Using the same rootless user, if I try to create a trace, I get the following error:
No profile or providers specified, defaulting to trace profile 'cpu-sampling'

what permissions is necessary to capture tracing using a rootless user?
Thank you!
