Flannel ==============
* Flannel configuration file should have been created there
``` cat /run/flannel/subnet.env FLANNEL_NETWORK=10.233.0.0/18 FLANNEL_SUBNET=10.233.16.1/24 FLANNEL_MTU=1450 FLANNEL_IPMASQ=false ```
* Check if the network interface has been created
``` ip a show dev flannel.1 4: flannel.1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc noqueue state UNKNOWN group default link/ether e2:f3:a7:0f:bf:cb brd ff:ff:ff:ff:ff:ff inet 10.233.16.0/18 scope global flannel.1 valid_lft forever preferred_lft forever inet6 fe80::e0f3:a7ff:fe0f:bfcb/64 scope link valid_lft forever preferred_lft forever ```
* Docker must be configured with a bridge ip in the flannel subnet.
``` ps aux | grep docker root 20196 1.7 2.7 1260616 56840 ? Ssl 10:18 0:07 /usr/bin/docker daemon --bip=10.233.16.1/24 --mtu=1450 ```
* Try to run a container and check its ip address
``` kubectl run test --image=busybox --command -- tail -f /dev/null replicationcontroller "test" created
kubectl describe po test-34ozs | grep ^IP IP: 10.233.16.2 ```
``` kubectl exec test-34ozs -- ip a show dev eth0 8: eth0@if9: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1450 qdisc noqueue link/ether 02:42:0a:e9:2b:03 brd ff:ff:ff:ff:ff:ff inet 10.233.16.2/24 scope global eth0 valid_lft forever preferred_lft forever inet6 fe80::42:aff:fee9:2b03/64 scope link tentative flags 08 valid_lft forever preferred_lft forever ```
