How about OS patching? If I am running hundreds of different containers and I need to patch the OS (let's say upgrade the kernel or a driver), will I affect hundreds of applications at once? If so this will be a problem for several shops.
How about built-in failover? On a virtualized environment you can run a cluster and the VM will move to another host in case of failure. Does docker support that? Is that what the docker-cluster project (https://github.com/globocom/docker-cluster https://github.com/globocom/docker-cluster) is about?
- lotyrin 13y agoOS updates (updates to files inside containers) would be on a per-container basis. Kernel upgrades would affect all of the containers running under that kernel (machine or VM) at the same time. Though, if you wanted to be super cautious, you could upgrade kernel on an empty container host (quite easy if virtualized) and migrate containers to it and test them on an individual basis.
