docker - 如何在Windows Container中获取Docker IP？

Question

我无法从浏览器获取容器IP地址来运行它。

代码段

PS H:\DevAreaLocal\COMPANY - RAD PROJECTS\DockerApp\WebDockerCoreApp> docker-compose build

PS H:\DevAreaLocal\COMPANY - RAD PROJECTS\DockerApp\WebDockerCoreApp> docker inspect --format="{{.Id}}" 7003460ebe84

有波纹管ID

sha256:7003460ebe84bdc3e8647d7f26f9038936f032de487e70fb4f1ca137f9dde737

如果我运行波纹管命令

docker inspect -f "{{ .NetworkSettings.Networks.nat.IPAddress }}" 7003460ebe84

得到以下回应

模板解析错误:模板:: 1:19:在<.NetworkSettings.Net ...>处执行“”:映射没有键“NetworkSettings”的条目

Docker.Compose.yml文件设置

version: '2.1'

services:
  webdockercoreapp:
    image: webdockercoreapp
    build:
      context: ./WebDockerCoreApp
      dockerfile: Dockerfile
    ports:
      - "5000:80"

networks:
  default:
    external:
      name: nat

通过敲“ docker network ls”

吼叫

NETWORK ID          NAME                       DRIVER              SCOPE

680d4b4e1a0d        webdockercoreapp_default   nat                 local

当我运行“ docker network inspect webdockercoreapp_default”

得到以下回应

Answer 1

当您运行命令docker inspect --format="{{.Id}}" 7003460ebe84时-您当前正在针对镜像ID(而非容器ID)运行此命令。

图像是您构建的静态 Assets ，容器是从中运行的。因此，您需要做的是首先通过以下方式使图像在线:

docker-compose up

现在您可以通过以下方式查看正在运行的容器:

docker ps

找到您想要的容器；假设它是 abcd1234
现在，您将能够对容器而非图像运行原始命令。

docker inspect --format="{{.Id}}" abcd1234

这将返回容器的完整SHA。并且由于您最初询问的是网络设置；您将可以运行以下内容:

docker inspect -f "{{ .NetworkSettings.Networks.your_network_here.IPAddress }}" abcd1234

如果不确定网络名称是什么(看起来应该是 nat)，只需执行完整的 docker inspect abcd1234并查看输出并根据需要调整过滤器即可。
