No available IPv4 addresses on this network's address pools: bridge #18527
Closed
Description
Hi there, one of my production host encountered the following error when starting a new container (creation when well, POST /start request failed):
no available IPv4 addresses on this network's address pools: bridge
The bridge network is the default one giving IPs on 172.17.0.0/16
There are not so many containers on the host (70, see docker info output below) So I suppose there are plenty of available addresses.
In the complete log I've a warning about umount ipc, but I suppose it's related to the cleaning of the container start after the IP allocation error.
What could be the source of that? Thank you very much.
