Should systemd work within containers?

[MACscr]

I have a container running Debian 8.2 and I would like to be able to use systemd on it like the rest of my debian systems in order to make it easier to manage. Anyway, I noticed it wasnt installed on the new guest i created, so i installed systemd, rebooted the system and then installed my custom service. Unfortunately it won't start though.

Doh, thought it was an LXC issue, but it was because I hadn't installed "systemd-sysv". Works now!

systemd can work in lxc CT, but only lastest version. (don't remember from which version exactly) Debian version is too old. Last ubuntu (willy) is working in lxc CT with systemd.

 

[windinternet]

The included centos 7 template also runs with systemd, it uses version 219. The Proxmox Jessie host uses 215, but the Debian 8 template does not have systemd pre-installed.

Please set your thread to solved.

Thank you.

Can you explain?

 

[fireon]

Can you explain?

Yes, this would be nice.

 

[dirk.nilius]

Systemd in Debian 8 containers works fine. Just install systemd-sysv package as mentioned:

apt-get install systemd-sysv

and reboot.

 

[camaran]

But first I must install systemd?

 

[fireon]

Systemd is default.

systemd will be installed as dependency if it's not already installed.
