Makes GID, UID and user as variables

[spassignat]

Hello,

the fixed values 999 for GID and UID and the user name postgres, are not always convenient when using docker-compose with several applications sharing the same host folder for their volumes.

Is it possible to make them variables ? defaulting their values ?

thanks

Just set --user/user: to whatever uid/gid that you desire and provide a directory owned by that user for the volume (/var/lib/postgresql/data). No variable is necessary, the images are designed to run as any arbitrary user.
