pgAdmin 4 is a web based administration tool for the PostgreSQL database. This is the official image provided by pgadmin. **REQUIRED Initial Setup** The Config directory mapped to appdata requires specific ownership by the non-root user pgadmin (inside the container). * Either create the folder mapped to Config in appdata before starting this container or wait for it be created on container startup. * Then open Unraid cli and change ownership for the directory to 5050:5050 with the following command chown -R 5050:5050 /mnt/user/appdata/pgadmin4 Restart the container to continue setup. More information on the mapped directory and other container options can be found here: https://www.pgadmin.org/docs/pgadmin4/latest/container_deployment.html#mapped-files-and-directories
