Advanced Sample

Build and run the sample container image; useful as an example or to test libnss_shim functionality.

Details

As defined in the Dockerfile, three Python scripts are installed in the container image and configured for use by libnss_shim:

• custom-group-resolver.py
• custom-passwd-resolver.py
• custom-shadow-resolver.py

Each script services requests for a specific NSS database. As set in custom_config.json, environment variables are used to pass data to the scripts.

Usage

Docker is required to proceed. Podman may also work, but this has not been tested extensively.

1. After cloning the repository, build the sample image as libnss_shim_container & run it:

   cd libnss_shim/samples/advanced
   docker build -t libnss_shim_container . && docker run --rm -it libnss_shim_container
   

2. Once in the container shell, make requests to test libnss_shim:

   getent group test-shim-users
   getent passwd | grep test-shim-user
   getent shadow test-shim-user-3
   

3. When finished, quit the container shell and delete the image:

   exit
   docker image rm libnss_shim_container
