Note: For any containers relying on any networking launched from a network driver (i.e. The default subnet is 10.42.0.0/16, but can be configured to your own subnet. The IP address of the network interface would be one from Rancher’s managed subnet. eth0) along with the loopback interface (i.e. Inside the container, the ip addr or ifconfig commands will show one network interface (i.e. Most of Rancher’s features, such as load balancers or DNS service, require the service to be in the managed network. All containers in the managed network are able to communicate with each other regardless of which host the container was deployed on.

Managedīy default, containers launched in Rancher using the UI or Rancher CLI use the managed network, which uses Rancher’s managed overlay network. In order to use container networking for a service, you can use either Rancher CLI, Rancher Compose or Docker CLI to launch the container.

In the UI, all options are available for services except for container networking. Services launched in the UI can change their networking options by navigating to the Networking tab when adding a service. If you are facing issues with cross host communication, please refer to our troubleshooting documentation. If you want to alter the communication between containers, you can set up a network policy. Communication Between Containersīy default, all containers within the same environment are reachable via the managed network. Any ports published on a host will not be shown in docker ps as Rancher manages separate IPtables for the networking. Certain images may not work if it requires a Docker bridge IP. The Rancher managed IP address will not be present in Docker metadata, which means it will not appear in docker inspect. With the adoption of the CNI framework, any container launched in managed network will only have the Rancher managed IP (default subnet: 10.42.0.0/16). When using Rancher’s IPsec networking prior to the 1.2 release, a container in the managed network would be assigned with both a Docker bridge IP ( 172.17.0.0/16) and a Rancher managed IP ( 10.42.0.0/16) on the default docker0 bridge. Any services using the managed network will be using this default network. When a network driver is launched into the environment, it automatically creates a default network. In our default environment templates, we have enabled IPsec network driver to create a simple and secure overlay network using IPsec tunneling. These services host internal DNS server and manage routing to published ports on the host (via iptables).īesides the Network Services infrastructure service, select which type of networking plugin/driver that you’d like your services to use. By default, all environment templates have the Network Services enabled. To leverage the CNI framework, an environment is required to use the Network Services infrastructure service deployed.

Rancher implements a CNI framework, which provides the ability to select different network drivers within Rancher. These docs are for Rancher 1.6, if you are looking for Rancher 2.x docs, see here.
