Installing the Rocket.Chat Snap on LXD



  • I put Ubuntu back on my laptop and I've been playing around with some of their stuff again since they have some pretty cool tech (Juju, MaaS, LXD, etc). I hate the fact that Red Hat pretty much abandoned LXC. It's painful on Fedora and even worse on CentOS.

    I might start using Ubuntu more, and 17.10 is pretty impressive as a workstation OS.

    Here's how easy it is to install Rocket.Chat with Snap on LXD.

  • @stacksofplates silly question time, why not just snap install rocketchat-server? Does lxc just start a container with a command?

    Well the first bit builds the container, then you need to install squashfuse so it has somewhere to store it's data or it bombs out. Then I finally ran that inside the container.



  • @travisdh1 He is running that command inside the container named rocketchat

    Ah, gotcha.



  • LXD is amazing, I agree that it's amazing on Ubuntu and so insane that it is missing on Fedora.



  • I use Snaps to install Rocket.Chat on Fedora.

    But isn't snap installs in Fedora have limitation compare to Ubuntu?

    Haven't run into any limitations.



  • Sadly, this doesn't seem to work anymore.

    Using Ubuntu 18.04.

    Snaps are broken on Ubuntu?

  • @aaronstuder Interesting. It's been great for us on Fedora, even on LXD. Ubuntu can run the LXC if you want, but run a Fedora container, not an Ubuntu one.



  • @scottalanmiller maybe it doesn't support 18.04 yet. I'll try a 17.04 container.

    Reboot the server. I'm running on Ubuntu 18.04 and it works.



  • @dafyre You mean the container? I did. Didn't Work.



  • @dafyre How did you install it?



  • @aaronstuder said in Installing the Rocket.Chat Snap on LXD:

    snap install rocketchat-server

  • Where are the snap logs located?



  • @aaronstuder said in Installing the Rocket.Chat Snap on LXD:

    Where are the snap logs located?

    I dunno. I journalctl -f or journalctl -xe if I'm having problems (or I try starting the snap while it's already running, lol).
