Proxmox / LXC – Running docker inside a container
In relation to Debian / Proxmox – Install Docker with Rancher and DockerUI webgui on a Debian / Proxmox Server
I thought that it actually may make more sense to run Rancher and my docker inside an LXC container rather than on the initial host itself.
Just found this on the Proxmox Wiki https://pve.proxmox.com/wiki/Performance_Tweaks#VZdump stating that the default value for vzdump is limited to 10000 Kbps (10 Mbps). This might explain even my misunderstanding why backups to my NAS are pretty “slow” sudo vi /etc/vzdump.conf showed that the original line in Proxmox 3.2 is #bwlimit: KBPS which I changed for now without notable issues to bwlimit: 40000 However James Coyle mentioned running into another issue with a too high value on undersized servers. http://www.jamescoyle.net/how-to/290-limit-backup-io-bandwidth You should keep that in mind if you are about to bring your server down while running vzdump backups.

This is a bizarre one. Either I wasn’t able to search for the right pages and posts or it’s simply poorly documented. Particularly under Proxmox (I will need to bump up my opennode to check on that one). One of the best features there, are the turnkey templates. Seriously, a few clicks and you have loads of great appliances up and running powered by turnkey templates. Sadly they are all Debian based but thats another story. But deploying and get it running such a template kind of was not straight forward. This applies to a “new” turnkey 13.1 template (I tried the nginx) You download the templates through the gui -> create a new CT -> give it your root password -> select the template -> install -> boot ->ssh to it (or maybe even try the Proxmox console) -> fail. At least in 3 cases on my systems I […]
