Does the Discourse docker container use unattended-upgrades to keep its Debian-backed docker container’s OS packages up-to-date? I noticed that the INSTALL-cloud.md guide recommends installing unattended-upgrades on the docker host machine, so I got wondering about the state of the OS packages insi…

After further digging, it appears that unattended-upgrades is installed but not running on the Discourse docker container. First, it’s clearly installed root@osestaging1-discourse-ose:/var/www/discourse# dpkg -l | grep -i unatt ii unattended-upgrades 1.11.2 all …

My guess is that it’s off on purpose as it might break something, and the image itself is updated when a serious security issue is found. You can enable it if you want, just enter the container.

Actually, I just realized that Discourse’s docker image is setup to use runit. Is systemd even installed on the Discourse docker container? My guess is not having systemd installed is what’s breaking unattended-upgrades.

Sounds right. Some people really don’t like systemd. So you can either trust that the base container gets updated regularly by people running a large team of professionals that depends on it, or you can do it some other way yourself and hope that you don’t break anything.

fyi, I fixed the broken unattended-upgrades install (which doesn’t actually run without systemd on the Discourse docker container) by triggering it to run via a cron job. I created the following yaml template file in my /var/discourse/templates/ dir to create the necessary cron job (note that it al…

It seems that it is enabled on a fresh Discourse docker image (running Debian 10). It is launched through runit → cron → /etc/cron.daily/apt-compat → /usr/lib/apt/apt.systemd.daily It was also running on a one-year-old Ubuntu 16-based docker image (based on discourse/base:2.0.20190321-0122), I am p…

いいえ、使用していませんし、今後使用させる予定もありません。推奨される方法は、ホスト OS を最新のセキュリティパッチで更新し続けることです。
