Docker update to latest version

[forummaster]

I followed the recommended installation guide here: discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub

These are the only commands required for docker install:
sudo apt install docker.io
sudo apt install git

Is that going to keep docker updated to the latest version?

I’m running Ubuntu server 22.04.

There is the updater in the web interface can be used to update docker and will tell you if it is up to date at (site url)/admin/update.

You can

apt-get update; apt-get upgrade

You can also configure apt to automatically apply updates and reboot if you search.

@pfaffman

apt get update; apt get upgrade

Wouldn’t it be apt-get?

“-get” is no longer required in Ubuntu, so just “apt” is fine for all commands.

My question was more related to Ubuntu repositories with docker and if they package the latest version. I can check with the 22.04 repos. Thanks

“apt upgrade” will update ubuntu, but does that update the docker?

For app rebuild is cd/var/discourse then ./launcher rebuild app

Manually update Discourse and Docker image to latest

If you self-host Discourse, you occasionally need to run a manual update via the command line to get the latest security releases newest libraries. These updates are not picked up in admin/update, which is why you’ll occasionally need to do this additional step. Discourse itself should be updated about twice a month, by clicking the “Update to Latest Version” button in your admin dashboard (admin/update). Every two months we recommend SSH’ing into your web server (using putty or your favor…

It should update docker since the original command is
sudo apt install docker.io so it is pulled from the ubuntu repositories.

From that guide referenced above:

@Discourse

Due to the way docker packaging has changed you may also have to update your docker from lxc-docker or docker-engine packages. One way to do that is via the Docker script here (it will warn about an existing install but should upgrade ok):

wget -qO- https://get.docker.com/ | sh

This will now use the docker-ce main versions.

Edit: This command seems to have caused site to crash, don’t recommend running that.
