泊坞窗不能指定容器连接
docker configure： root@ubuntu> ps -ef | grep docker root xxxxx /usr/bin/dockerd -H fd:// -b=br0 --icc=false --iptables=true root@ubuntu> ps -ef | grep docker root xxxxx /usr/bin/dockerd -H fd:// -b=br0 --icc=false --iptables=true
启动'web'容器：
docker run -d --name web -p 8080:80 php-fpm:5.4
开始“testing”容器：
docker run -dit --name test --link web:web blackhole/ubuntu:0.1 bash
iptablesfilter：
root@ubuntu> sudo iptables -L -n Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy DROP) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination Chain DOCKER (0 references) target prot opt source destination ACCEPT tcp -- 0.0.0.0/0 192.168.100.2 tcp dpt:80 ACCEPT tcp -- 192.168.100.3 192.168.100.2 tcp dpt:80 ACCEPT tcp -- 192.168.100.2 192.168.100.3 tcp spt:80 ACCEPT tcp -- 192.168.100.3 192.168.100.2 tcp dpt:443 ACCEPT tcp -- 192.168.100.2 192.168.100.3 tcp spt:443 ACCEPT tcp -- 192.168.100.3 192.168.100.2 tcp dpt:22 ACCEPT tcp -- 192.168.100.2 192.168.100.3 tcp spt:22
在“testing”容器中：
sudo docker exec -it test bash root@00585b9efea8:/# cat /etc/hosts 127.0.0.1 localhost ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters 192.168.100.2 web 2cec3235f5fa 192.168.100.3 00585b9efea8 root@00585b9efea8:/# ping web PING web (192.168.100.2): 56 data bytes ^C--- web ping statistics --- 12 packets transmitted, 0 packets received, 100% packet loss root@00585b9efea8:/# ping 192.168.100.2 PING 192.168.100.2 (192.168.100.2): 56 data bytes ^C--- 192.168.100.2 ping statistics --- 12 packets transmitted, 0 packets received, 100% packet loss root@00585b9efea8:/# curl web ^C root@00585b9efea8:/# curl http://192.168.100.2:80 ^C
指定容器的三个条件：
–icc = FASLE
–iptables =真
– 链接
没问题，为什么不呢？
ubuntu版本：16.04.2 LTS docker版本：.13.1内核版本：4.9.0-040900-generic
link选项已被弃用 。 对于基于DNS的服务发现，您应该创build一个新的桥接networking，并指定--net以使--net容器join此networking：
创build新的桥接networking：
docker network create --subnet=192.168.177.0/24 --gateway=192.168.177.1 www
在这个networking上创build两个容器：
docker run -d --name=nginx1 --net=www nginx:1-alpine docker run -d --name=nginx2 --net=www nginx:1-alpine
试着用名字ping对方：
docker exec -it nginx1 /bin/sh / # ping nginx2 PING nginx2 (192.168.177.3): 56 data bytes 64 bytes from 192.168.177.3: seq=0 ttl=64 time=0.113 ms 64 bytes from 192.168.177.3: seq=1 ttl=64 time=0.123 ms --- nginx2 ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max = 0.113/0.118/0.123 ms
您可以通过执行docker network inspect www在这个networking上查看容器
