我使用该命令启动了一个rethinkDB docker容器
docker pull rethinkdb:2.3
docker run --rm --name rethinkdb -v /srv/rethinkdb:/data --net host rethinkdb:2.3 rethinkdb --bind all --cache-size 8192 --no-update-check
现在容器已成功启动.我做了docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
f288961ef376 rethinkdb:2.3 "rethinkdb --bind ..." 9 minutes ago Up 9 minutes rethinkdb
1f71722698ae sorccu/adb:latest "/sbin/tini -- adb..." 14 minutes ago Up 14 minutes adbd
现在我想找出这个容器的IP地址.所以我做了
docker inspect --format '{{ .NetworkSettings.IPAddress }}' f288961ef376
它什么也没归我.我找不到这个容器的IP地址.
我通过访问http：// localhost：8080检查了rethinkDB配置页面是否已启动,我看到它已启动并正在运行.
为什么这个容器没有任何IP地址？
码头检查的输出如下

最佳答案
您正在使用–net host选项启动容器,这意味着您的容器将在主机网络上运行.检查here以获取更多信息.因此,您的容器可以通过主机的IP访问.
一个非常基本的例子：
$docker run --net=host -d jenkins
这将在您的真实主机网络上运行jenkins.因此,当您打开防火墙(jenkins在8080上运行)时,您将立即访问您的容器.
所以我打开防火墙：
$sudo iptables -I INPUT 5 -p tcp -m tcp --dport 8080 -j ACCEPT
我使用ifconfig检查我的eth0(主机网络)的真实IP. (我在VM上这样做).它是192.168.140.7.我在浏览器中访问192.168.140.7:8080,我看到了jenkins.所以你的容器没有自己的IP.它在您的主机网络和主机IP上运行.
如果保留–net host选项,则将在默认的docker bridge网络中创建容器,范围为“172.17.0.0/16”.现在,您的容器将从该网络的范围内获取IP.要从外部访问容器,您必须在主机网络上映射端口(请参阅更多信息).您可以使用-p选项执行此操作.
所以对于jenkins的例子：
$docker run -d -p 8888:8080 jenkins
当我执行码头工作检查时,我看到：
"IPAddress": "172.17.0.4",所以我的容器在172.17.0.4:8080的桥接网络中运行.
现在使用-p选项我将我的桥接网络的端口8080映射到我的主机网络的8888上：所以host-IP：8888.现在它可以从外面访问.
