fmarinheiro/dotnet_core_dev repository overview

⁠.Net Core development docker image

This images builds on microsoft/dotnet:latest to better integrate with the hosts file system so you don't run into permission problems.

• Create a new user named app that will assum the user and group id from the HUID and HGID environment variables.
• The default user app will have the /home/app home folder
• Install debugger for vs code
• Create the workspace folder inside the users home to mount the app files from the host

By default, running the images without specifying a command will open bash for the app user.

docker run -it fmarinheiro/dotnet_core_dev

If a command is specified it will execute it with the app user.

docker run -it fmarinheiro/dotnet_core_dev dotnet --help

On your local machine to avoid permission problems you should run the image providing you own user anf group id to the image.

docker run --name my_container -p 5000:5000 -it  -v $PWD:/home/app workspace fmarinheiro/dotnet_core_dev

This will open a bash where you can execute you dotnet commands as a non root user, and the file permissions of files created by the container will be right on the hosts side.

If you prefer you can use docker exec:

 docker exec --user app encryptor_app dotnet build
