Update rockets up resources

[gjpc]

I just updated to 19.1.20190813 on my AWS T1 micro. To my horror, memory usage tripled. It appears the default action of of the webmin update command is to install the entire rocket chat system.

apt-get -y install egroupware-docker

Rocket chat is not needed nor wanted. I do not think it should be automatically installed with either a fresh install of Egroupeware nor an update of the egroupware-docker package.

I had to perform a apt remove to restore my system resources to a tolerable level.

apt remove  egroupware-rocketchat:amd64

Please consider not installing rocket chat as a default component of egoupware under a webmin update. At a minimum, if rocket chat is not already installed during an update ask the user if the rocket chat component should be added.

Also I don’t seem to remember the processes below. Are they part of the rocket interface? My memory usage is still not back down to below half a GB. Is there anything else I can remove that would let just plain vanilla egroupware run? There does not appear to be any separate rocket mysql tables.

2407 	root 	10.37 MB 	containerd-shim -namespace moby -workdir /var/lib/containerd/io.containerd.runti ...
2410 	root 	10.37 MB 	containerd-shim -namespace moby -workdir /var/lib/containerd/io.containerd.runti ...
2415 	root 	10.37 MB 	containerd-shim -namespace moby -workdir /var/lib/containerd/io.containerd.runti ...
2846 	systemd-timesync 	6.39 MB 	nginx: worker process
2600 	root 	5.91 MB 	nginx: master process nginx -g daemon off;

Is there anyway to lower the memory usage of these processes?

1388 	root 	763.71 MB 	/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
3172 	www-data 757.30 MB 	php-fpm: pool www
2561 	root 	754.97 MB 	php-fpm: master process (/etc/php/7.3/fpm/php-fpm.conf)
3173 	www-data 754.97 MB 	php-fpm: pool www
1314 	root 	659.59 MB 	/usr/bin/containerd

Should I just go back to version 17?

Neither Rocket.Chat nor Collabora Online Office is package-wise required, it get’s recommended.
Recommending them was announced in the changelog: https://github.com/EGroupware/egroupware/releases/tag/19.1.20190813

Recommeds are installed by default, but can be easily avoided, by using the --no-install-recommends to apt(-get).

Just for everyones information Rocket.Chat requires about 500MB of ram independent of usage. So not installing it or deinstalling it after you found it not useful makes sense.

Thanks for the reply Ralf.

I am trying to point out that Webmin, a very popular linux system administration tool, uses the -y option on package updates. Now egroupware has to be updated by hand in a command shell instead of using the Webmin tool for those of us with small resources on our servers.

I’d also like to point out that egroupware-docker and egroupware-rocketchat:amd64 are two separate packages that are not co-dependent. There is no practical reason for egroupware-docker to install rocket. It’s like pascal automatically installing modula-2 when it’s updated even though modula-2 is not installed on the system. I am sure some installations using rocket may even want to install rocket on a different server.

May I point out that the apt-install -y of egroupware-docker did not install Collabora Online Office? Rocket should be treated just the same as Collabora on updates.

Also is there a way to trim down the memory footprint of docker given that there are only two users on my Egroupware installation?

[RalfBecker]

The weak dependency is not a technical one, but a logical one:

• we believe both Rocket.Chat and Collabora Online Office are a requirement for a modern collaboration tool
• if a new module is not installed by default, most user will not recognize it is available now

Maybe Webmin has a setting or preference to not make that decision on your behalf, but prompt you that it is going to install these dependencies so you can pass a flag to not install recommended (but not required) packages, as apt on the command line does.

May I point out that the apt-install -y of egroupware-docker did not install Collabora Online Office? Rocket should be treated just the same as Collabora on updates.

That is NOT true, egroupware-docker recommends egroupware-rocketchat AND egroupware-collabora-key.

Also is there a way to trim down the memory footprint of docker given that there are only two users on my Egroupware installation?

Docker in general does not have a high memory footprint, nor has the egroupware-docker package.

Rocket.Chat using Meteor framework and node.js is a different story. It requires 500MB just for starting it.
I’m not aware that there is anything you can do about that.

If you don’t need a messenger, or can not effort to run one with the resource your host has available, you can deinstall it and AFAIK apt upgrade will not try to reinstall it. Same is true for Collabora.
