Diagnostics: Cannot install dotnet-dump in Docker

[klesta490]

Hi!
I am unable to install dotnet tools in Docker.

I am using docker image
mcr.microsoft.com/dotnet/core/runtime:3.0-buster-slim

There is no SDK so we need to install it.
docker exec -it my_container /bin/bash

apt update
apt install gnupg
apt install wget

wget -qO- https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.asc.gpg
sudo mv microsoft.asc.gpg /etc/apt/trusted.gpg.d/
wget -q https://packages.microsoft.com/config/debian/10/prod.list
sudo mv prod.list /etc/apt/sources.list.d/microsoft-prod.list
sudo chown root:root /etc/apt/trusted.gpg.d/microsoft.asc.gpg
sudo chown root:root /etc/apt/sources.list.d/microsoft-prod.list

sudo apt-get update
sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install dotnet-sdk-3.0

Now I can finally install dotnet-dump to dump problematic process. But I get following error:

root@7b401dc43c94:/dotnetcore# dotnet tool install -g dotnet-dump
System.ComponentModel.Win32Exception (0x80004005): The FileName property should not be a directory unless UseShellExecute is set. at System.Diagnostics.Process.StartCore(ProcessStartInfo startInfo) at System.Diagnostics.Process.Start() at Microsoft.DotNet.Cli.Utils.Command.Execute() at Microsoft.DotNet.Tools.Tool.Install.ProjectRestorer.Restore(FilePath project, PackageLocation packageLocation, String verbosity) at Microsoft.DotNet.ToolPackage.ToolPackageInstaller.<>c__DisplayClass5_0.<InstallPackage>b__0() at Microsoft.DotNet.Cli.TransactionalAction.Run[T](Func`1 action, Action commit, Action rollback) at Microsoft.DotNet.ToolPackage.ToolPackageInstaller.InstallPackage(PackageLocation packageLocation, PackageId packageId, VersionRange versionRange, String targetFramework, String verbosity) at Microsoft.DotNet.Tools.Tool.Install.ToolInstallGlobalOrToolPathCommand.Execute() at Microsoft.DotNet.Tools.Tool.Install.ToolInstallCommand.Execute() at Microsoft.DotNet.Cli.DotNetTopLevelCommandBase.RunCommand(String[] args) at Microsoft.DotNet.Tools.Tool.ToolCommand.Run(String[] args) at Microsoft.DotNet.Cli.Program.ProcessArgs(String[] args, ITelemetry telemetryClient) at Microsoft.DotNet.Cli.Program.Main(String[] args)

Any advice?

We're actively looking at mechanisms for reliably installing these tools without the SDK requirement, so keep an eye out for that.

That exception smells like https://github.com/dotnet/corefx/issues/40850 (more links: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1843018, https://github.com/moby/moby/issues/39875).
