Sure you CAN run an embarassingly stateful system like a RDBMS on a containerization platform designed to run stateless, throw-away-and-rebuild-on-a-whim-type services - but the question is, why would you? What specific problem are you hoping to solve by doing so? This considered, performance by having Docker (or any other means of technology that uses Linux namespace- and cgroup-subsystems) in the mix PROBABLY won't suffer noticeably, UNLESS you get bitten by problems lurking in the pieces of the puzzle that are storage drivers (AUFS and friends) and enable container networking, which is not unheard of. -- with best regards: - Johannes Truschnigg ( johannes@xxxxxxxxxxxxxxx ) www: https://johannes.truschnigg.info/ phone: +43 650 2 133337 xmpp: johannes@xxxxxxxxxxxxxxx Please do not bother me with HTML-email or attachments.
