Dotnet build permission denied in Docker container running Jenkins

Question

I am trying to build a .NET application using Jenkins. The Jenkins instance is running in a Docker container.

My Jenkinsfile is as follows:

pipeline {
          


        

Answer 1

The issue appeared to be linked to trying to write data to the top level of the Docker container ('/').

Adding the following to the Jenkinsfile ensures that the home directory is set and the .dotnet folder can be created in a location with correct permissions.

environment {
   HOME = '/tmp'
}
