  • You would expose the port to your host which makes the db acessible by anything running on the host, docker or native. Something like

    `port

    • 5432:5432 `

    But I would recommend running a dedicated db for each service. At least that’s what I do.

    • Simpler setup and therefore less error-prone
    • More secure because the db’s don’t need to be exposed
    • Easier to manage because I can independently upgrade, backup, move

    Isn’t the point about containers that you keep things which depend on each other together, eliminating dependencies? A single db would be a unecessary dependency in my view. What if one service requires a new version of MySQL, and another one does not yet support the new version?

    I also run all my databases via a bind mount

    `volume

    • ./data:/etc/postgres/data…`

    and each service in it’s own directory. E.g. /opt/docker/nextcloud

    That way I have everything which makes up a service contained in one folder. Easy to backup/restore, easy to move, and not the least, clean.

    But seriously, I was wondering about the requirement to shutdown the VM’s and couldn’t come up with a solid reason? I mean, even if QEMU/KVM/Kernel get replaced during a version upgrade or a more common update, all of these kick in only after the reboot? And how’s me shutting down VMs manually different from the OS shutting down during a reboot?

    I know I am speculating and may not have the fill picture, probably a question for the Proxmox team, there may be some corner case where this is indeed important.

    By the way, Mexican or US black strat? :-)
