Re: Postgresql + containerization possible use case

Hi
we are running some 140 remote servers (in the 7 seas via satellite connections), and in each one of them we run:
- jboss
- postgresql
- uucp (not as a daemon)
- gpsd
- samba
- and possibly some other services

Hardware and software upgrades are very hard since there is no physical access to those servers by trained personnel, and also there is a diversity of software versions.

The idea for future upgrades is to containerize certain aspects of the software. The questions are (I am not skilled in docker, only minimal contact with lxd) :
- is this a valid use case for containerization?
- are there any gotchas around postgersql, the reliability of the system ?
- since we are talking about 4+ basic services (pgsqk, jboss, uucp, samba), is docker a good fit or should we be looking into lxd as well?
- are there any success stories of other after following a similar path?
