Docker alongside FreePBX (NOT to run FreePBX from...)

I need to give someone I trust access to the same server I run FreePBX from to do some development work. This has obvious grave security implications even though I trust this person.

So I thought - would Docker be the solution to my problem?

Does anyone know if I can install Docker alongside FreePBX (CentOS) and by that method ‘jail’ the user so they can’t inadvertently wreak havoc on the server?

Cheers!
