What is the purpose of "samba samba-common-tools openssh sshpass" packages in docker image?

Hi,

Question is in the title :)

Why do we need following packages: "samba samba-common-tools openssh sshpass" inside the production docker image ?

From a security aspect removing by hardening the image could reduce surface attack on this container.

Thanks for the help

Samba packages are need for shutting down windows hosts via net rpc.

OpenSSH and sshpass are needed for shutting down linux hosts.

Both are essential for upsnap and don't offer much attach surface (normally - looking at you xz).

Make sense to me now.

Thanks for your quick answer and your work :).
