LGTM but I still don't understand what the new user 'user' is for?

LGTM but I still don't understand what the new user 'user' is for?

I always run the spksrc container with docker run -it .... --user $(id -u):$(id -g) ... synocommunity/spksrc:latest

So all file modifications in the mounted /spksrc folder in the container are done with my host user, and therefore I have full access without root on the host.
Without the user user inside the container the user is I have no name!.
I know that this works only due when the host user id is 1000 (the same as the user has inside the container).

Finally we need a dedicated user in the container that works with sudo without password if one want to avoid using root.

This is for a future update to eliminate to build native binaries (cmake, go, etc.) and to use apt-get install to install such prerequisites instead.

@hgy59 Thanks 👍

Rather than --user $(id -u):$(id -g) you could add the USER user or USER 1000:1000 to the image, so this is done by default? Maybe add a group for the id 1000 as well?

Maybe add a group for the id 1000 as well?

The group 1000 (user) is created by default for the user user.

$ cat /etc/passwd | grep user
user:x:1000:1000:,,,:/home/user:/bin/bash

Is it possible to get the image on docker hub updated?

@ymartin59 how to trigger an update of the docker hub image?

I used a github action to build the image: https://github.com/publicarray/spksrc/pkgs/container/spksrc and https://hub.docker.com/r/publicarray/spksrc
