通过容器IP访问Docker不起作用，但可以通过Localhost访问
我一直在学习Docker，我了解到的一件事是，如果端口在容器中公开并且应用程序在该端口正在运行，那么您可以使用http：// container_ip：port port 访问它。已经进行了测试，并且总是有效的。
但是今天，在使用Angular应用程序执行此操作的同时，我发现我无法访问URL，并且不会返回任何内容。 神奇地我想到击中http：// localhost：port and and ant ant ant and ant and ant and and other，这是怎么可能的，为什么它甚至首先发生？
dockerfile
# Stage 1
FROM node as build-step
RUN mkdir -p /app
WORKDIR /app
COPY package.*json /app
RUN npm install
COPY . /app
# RUN npm install -g ts-node
RUN npm run build
# Stage 2
FROM nginx
EXPOSE 80
COPY --from=build-step /app/dist/test-app /usr/share/nginx/html
任何帮助都将受到赞赏。
I have been learning docker and one thing I learned is that if a port is exposed in a container and an application is running at that port then you can access it using http://container_IP:port which I have tested and it always works.
But today while doing the same with an Angular app, I found that I can't access the URL and it does not return anything.
Magically I thought of hitting http://localhost:port and it worked, how is this possible and why did it even happen in the first place?
Dockerfile
# Stage 1
FROM node as build-step
RUN mkdir -p /app
WORKDIR /app
COPY package.*json /app
RUN npm install
COPY . /app
# RUN npm install -g ts-node
RUN npm run build
# Stage 2
FROM nginx
EXPOSE 80
COPY --from=build-step /app/dist/test-app /usr/share/nginx/html
Any help is appreciated.

您不应该使用容器IP地址
这就是为什么您要公开
端口，因为要映射container端口到localhostportYou shouldn't use container IP address
that's why you are exposing the
portbecause you want to mapcontainerport tolocalhostport
