I just started with rancher 1.0 and am unable to get a managed networking container started.
Tested this with Docker 1.10.3 on both Debian Jessie and CentOS 7.
I start up rancher/server and add my host with no issue. I then try to “Add Container” in Infrastructure->Hosts on a specific host with no specific options other than the image and name. The “Network Agent” starts up and gets an IP. The container then show “Starting (Networking)” and doesn’t get past that. If I create the container with “Host” or “Container” or “None” network, it is fine.
I’ve disabled ipv6 on the host machine but that didn’t help.
I thought it might have been a conflict on the 10.42.0.0/16 subnet as I have some IPs in that range. After switching that in v1/settings/docker.network.subnet.cidr and remaking the environment, that didn’t help the issue either.
