Thanks for writing this software.

When attempting to connect to caddy-docker-proxy container, I get an error. Environment is Rocky Linux 9.3 VM on ESXi server (64 bit Intel).

[jeffl@portainer10 ~]$ cdebug -v
cdebug version 0.0.16 (built: 2024-02-18T15:19:35Z commit: 3a7b9f64339229e0bf3ca2bf55b5e724ef851b5e)

Interesting! The exec command works just fine if you specify the shell explicitly:

$ cdebug exec -ti <container_id> sh
/ # 
/ # ps auxf
PID   USER     TIME  COMMAND
    1 0         0:00 /bin/caddy docker-proxy
   56 0         0:00 sh /.cdebug-entrypoint.sh
   65 0         0:00 sh
   66 0         0:00 ps auxf

It's a regression from the recent batch of changes. However, instead of reverting the change, I'll try merging #12 tomorrow - in particular, it should fix it.
