Start off by logging into your UpCloud control panel and deploying two CoreOS nodes for the Docker Swarm and a third node for the load balancer. Depending on the type of interface (macvlan, bridge, loopback) you can specify respective configurations in the conf file, the following link can be used for reference example configurations. 1 \ -o parent=eno1 \ pub_net And start new container with the new network:. Configure master/default CNI. The MACVLAN driver allows to create multiple virtual network devices on top of a single NIC, each of them identified by its own unique MAC address. Docker macvlan routing | unRAID to containers. Method 1: Configure Static IP Address in Arch Linux using netctl. Notes: You can use any route options described in "Route management" section in policy routes too, the only difference is the "table ${table id/name}" part at the end. Luckely, a solution exists - creating another macvlan interface on the host, and using that to access those containers. The eth0 interface on the pi has promiscuous mode enabled. Viewed 2 times 0. If the destination is on the local host, e. 在我的N1上运行route -n命令结果是我上面贴的结果, Metric 一个是0 还一个是100,其他字段都一样。 用你的那个变量对应命令取出来是2个网关, gw变量打印出来值是 192. 7 KB: Wed Apr 3 10:16:26 2013: 6rd_2-1_all.
