Provisioning Pod Network Routes

Flannel

Use flannel to solve communication problems between pods.

wget -q --show-progress --https-only --timestamping \
	"https://raw.githubusercontent.com/coreos/flannel/v0.12.0/Documentation/kube-flannel.yml"

Add --iface-regex=192.168.100. at line 192 in the command args of the amd64 container image.

Resultant kube-flannel.yml should now contains:

      containers:
      - name: kube-flannel
        image: quay.io/coreos/flannel:v0.12.0-amd64
        command:
        - /opt/bin/flanneld
        args:
        - --ip-masq
        - --kube-subnet-mgr
        - --iface-regex=192.168.100.


kubectl apply -f kube-flannel.yml

output

clusterrole "flannel" created
clusterrolebinding "flannel" created
serviceaccount "flannel" created
configmap "kube-flannel-cfg" created
daemonset "kube-flannel-ds" created

Verify

kubectl -n kube-system get pods

output

NAME                    READY     STATUS    RESTARTS   AGE
kube-flannel-ds-8p2pd   1/1       Running   0          1m
kube-flannel-ds-9mxnc   1/1       Running   0          1m
kube-flannel-ds-ldfq6   1/1       Running   0          1m

同时 worker 状态也会更新为Ready。

kubectl get nodes

output

NAME       STATUS    ROLES     AGE      VERSION
worker-0   Ready     <none>    3m       v1.8.0
worker-1   Ready     <none>    3m       v1.8.0
worker-2   Ready     <none>    3m       v1.8.0
