Before Docker 1. network "host" is declared as external, but it is not in the right scope: "local" instead of "swarm". I need to configure a static IP because external hosts will need to use one of the containers. Then, the Docker daemon routes traffic to containers by their MAC addresses. Kolla puts nearly all of persistent data in Docker volumes. However, it allocates from it’s own IP pool and won’t use your DHCP server. iface mac0 inet static. 1 then a Macvlan Docker. You can't access the functions inside it until you reference it in your project. Here only the range 192. address=none ipv6. I'll get right down to it: I have a docker-compose file where I specify this: networks: default: external: name: macvlan-nat And here's my network creation command for macvlan-nat. 110 ping statistics --- 3 packets transmitted, 0 packets received, 100% packet loss 这是 macvlan 的特性,目的是为了更好地实现网络的隔离,和 docker 无关。 参考资料. This can be simpler than having to manage the port space of a limited number of shared IP addresses when manually assigning external IPs to services. While all kernels should work for Docker, some older kernels may have issues with some of the different Docker back ends such as AUFS and OverlayFS. Scopes can filter hosts by name, MAC address, and operating system to either allow them or disallow them from receiving an IP address. Get started with Docker today. Install prerequisites […].
