问题
I am working on having Jenkins build our legacy .NET 2.1 applications as part of streamlining our kubernetes deployments
Therefore I have created a custom Jenkins agent based on the jenkins/jnlp-slave:latest-jdk11 docker image (https://github.com/jenkinsci/docker-jnlp-slave) which in turn is Debian 9 based, extended with the official .NET Core (unpacked the ZIP from https://dotnet.microsoft.com/download/dotnet-core/2.1 , Debian updates does not work well with our firewall), and for trivial projects this has worked well.
Now I try with a real legacy application which builds nicely when running the commands from the command line, but when Jenkins try to run dotnet restore -v n the build immediately fails with:
+ dotnet restore -v n

Not being very experienced with .NET, I have probably missed a step somewhere when setting up the environment. The application needs to run in the "da-DK" locale.
I understand that some part is missing. How should this fixed? I am interested in both project-specific quick solutions and long-term agent-specific solutions.
回答1:
After locating https://docs.microsoft.com/da-dk/dotnet/core/tools/dotnet-install-script on the download page, and seeing the "needed dependencies" link combined with the output from the install script, I found that the underlying reason was missing library dependencies, and the fix was to install them in the Dockerfile.
# Needed dependencies...
RUN apt install -y libunwind8 libicu57
