我使用命令启动了一个 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。所以我做到了 docker inspect --format '{{ .NetworkSettings.IPAddress }}' f288961ef376它什么也没给我。我找不到这个容器的 IP 地址。 我通过转到 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 IP 地址？ docker inspect的输出如下 [ { "Id": "f288961ef376531c97d2264cb8ef3c6077a6a75107905d6a47734303adfcb117", "Created":

here了解更多信息。因此，您的容器将可以在您的主机的 IP 上访问。 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。 于是我打开了防火墙: $ 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。 (我在虚拟机上做这个)。它是 inet 192.168.140.7。我在浏览器中进入 192.168.140.7:8080 并看到 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。 如果您保留 --net host 选项，容器将在默认的 docker bridge 网络中创建，范围为 "172.17.0.0/16"。现在您的容器将从该网络范围内获得一个 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 选项来做到这一点。 所以对于 Jenkins 的例子: $ docker run -d -p 8888:8080 jenkins当我执行 docker inspect 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，我将桥接网络的端口 8080 映射到主机网络的 8888 上:所以 host-IP:8888。现在它可以从外部访问了。 关于docker - 我的 Docker 容器没有 IP 地址。为什么？，我们在Stack Overflow上找到一个类似的问题：
