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 {

You can set the HOME environment variable as @colmulhall suggested, but then you will set the docker container home directory to /tmp.

To do it in "dotnet" way set the environment variable DOTNET_CLI_HOME:

environment {
    DOTNET_CLI_HOME = "/tmp/DOTNET_CLI_HOME"
}

Or before calling dotnet run:

export DOTNET_CLI_HOME="/tmp/DOTNET_CLI_HOME"

Update

A sample Jenkins pipeline code taken from https://www.jenkins.io/doc/pipeline/tour/environment/

Look how DOTNET_CLI_HOME is defined in the environment section:

pipeline {
    agent {
        label '!windows'
    }

    environment {
        DISABLE_AUTH = 'true'
        DB_ENGINE    = 'sqlite'
        DOTNET_CLI_HOME = "/tmp/DOTNET_CLI_HOME"
    }

    stages {
        stage('Build') {
            steps {
                echo "Database engine is ${DB_ENGINE}"
                echo "DISABLE_AUTH is ${DISABLE_AUTH}"
                sh 'printenv'
            }
        }
    }
}

There are many ways to achieve this. If you are using docker, maybe a better way is defining the environment variable DOTNET_CLI_HOME in the docker image.
