Does anyone interested to realize docker support in Proxmox?
It's really good feature, therefore I'm asking about it. Once Proxmox droped OpenVZ and started using LXC, may be it's time to add native docker support?I think supporting native docker will give Proxmox another boost, because it already can use LXC and KVM.
have you tried LXC? It is very fast .I'm going to find out what happens if I just install Docker on one of my bare-metal proxmox hosts, by adding the Debian Jessie apt repository and just installing it that way..
I know it would be a safer move to just run it in a KVM guest, but bare metal performance would be great to get more bang for the buck from a proxmox host .. bad idea? Who knows
Yep, I'm using a few LXC machines on Proxmox it is very cool. But What I am asking is if I can also run Docker on the host O.S. (Proxmox).have you tried LXC? It is very fast .
since the 90's we have used vservers, then openvz and now lxc. they are all close to bare metal speed. LXC looks to be future proof as no special kernel is needed.
Hello.... It is much harder to control layer 3 in a KVM VM then in a container.
Yes and no. Docker is outside of Proxmox's scope (at least today,) BUT there is nothing stopping you from installing Docker on a proxmox node- you'll just have no exposure of its management through Proxmox's GUI or API. You will not have any node fault tolerance (which is also true for LXC,) and you will also have to contend with competing system load from Proxmox and Docker, which do not know about each other's existence.But What I am asking is if I can also run Docker on the host O.S.
Depending on your use case this may not be a problem. On the upside, you gain cluster failover capability.SO you can run Docker inside a KVM machine no problem of course but then it's not bare metal.
OSI model Layer 3 refers to functionality at the IP address level. In other words, if you wanted to set or change an IP address using the Proxmox API, thats a very simple operation for a container; To do the same with a VM is a far more complicated operation and requires third party tools or custom scripts.RobFantini said:could you give an example of ' control layer 3' ? like which service or application could use it.
That actually made me laugh. By that logic, what is the value that proxmox offer docker users at all? Since, by design, Docker is replacing the hypervisor all Proxmox is doing is adding an unnecessary abstraction layer to the metal. Its not really my business but you may want to listen to your users- containerization is replacing the hypervisor, and if you dont adapt your product will become obsolete.Docker and kubernetes run perfectly inside a VM, so there is no real value to integrate that into proxmox itself.
