+Frakti is using CNI for setting up pod's networking. A list of validated plugins includes
+
+- Bridge
+- Flannel
+- Calico
+
+## [Bridge](https://github.com/containernetworking/plugins/tree/master/plugins/main/bridge)
+
+Firstly, install CNI:
+
+```sh
+$ sudo mkdir -p /etc/cni/net.d  /opt/cni/bin
+$ git clone https://github.com/containernetworking/plugins $GOPATH/src/github.com/containernetworking/plugins
+$ cd $GOPATH/src/github.com/containernetworking/plugins
+$ ./build.sh
+$ sudo cp bin/* /opt/cni/bin/
+```
+
+Then config CNI to use bridge and portmap plugin:
+
+```sh
+$ sudo sh -c 'cat >/etc/cni/net.d/10-mynet.conflist <<-EOF
+{
+    "cniVersion": "0.3.1",
+    "name": "mynet",
+    "plugins": [
+        {
+            "type": "bridge",
+            "bridge": "cni0",
+            "isGateway": true,
+            "ipMasq": true,
+            "ipam": {
+                "type": "host-local",
+                "subnet": "10.30.0.0/16",
+                "routes": [
+                    { "dst": "0.0.0.0/0"   }
+                ]
+            }
+        },
+        {
+            "type": "portmap",
+            "capabilities": {"portMappings": true},
+            "snat": true
+        }
+    ]
+}
+EOF'
+$ sudo sh -c 'cat >/etc/cni/net.d/99-loopback.conf <<-EOF
+{
+    "cniVersion": "0.3.1",
+    "type": "loopback"
+}
+EOF'
+```
+
+## [Flannel](https://github.com/coreos/flannel)
+
+Remove other cni network configure if they are already configured:
+
+```sh
+rm -f /etc/cni/net.d/*
+```
+
+Then setup flannel plugin by running:
+
+```sh
+kubectl create -f https://github.com/coreos/flannel/raw/master/Documentation/kube-flannel-rbac.yml
+kubectl create -f https://github.com/coreos/flannel/raw/master/Documentation/kube-flannel.yml
+```
+
+## [Calico](https://www.projectcalico.org)
+
+Remove other cni network configure if they are already configured:
+
+```sh
+rm -f /etc/cni/net.d/*
+```
+
+Then setup calico plugin by running:
+
+```sh
+kubectl apply -f https://docs.projectcalico.org/v2.4/getting-started/kubernetes/installation/hosted/kubeadm/1.6/calico.yaml
+```
