docker network (三):容器中添加網(wǎng)絡(luò)（指定固定IP）
docker network connect
docker network connect --help
Usage: docker network connect [OPTIONS] NETWORK CONTAINER
Connect a container to a network
Options:
--alias strings Add network-scoped alias for the container
--ip string IPv4 address (e.g., 172.30.100.104)
--ip6 string IPv6 address (e.g., 2001:db8::33)
--link list Add link to another container
--link-local-ip strings Add a link-local address for the container
（1）已運(yùn)行容器添加IP地址
真好乍恐，幫助命令已經(jīng)給出用法了评疗。 這個(gè)時(shí)候我運(yùn)行一個(gè)鏡像。
docker run -it alpine:latest sh
使用ifconfig命令茵烈，查看當(dāng)前網(wǎng)絡(luò)狀態(tài)百匆。
ifconfig
eth0 Link encap:Ethernet HWaddr 02:42:AC:11:00:03

這個(gè)時(shí)候，在容器外部呜投，執(zhí)行
docker network connect操作
docker network connect --ip 172.18.0.100 test_network 1366d90d4ca2添加網(wǎng)絡(luò) 172.18.0.100 地址到 1366d90d4ca2 容器中

docker run -it --network test_network --ip 172.18.0.101 alpine:latest sh
ifconfig
