Windows Docker容器没有NAT IP地址。 无法在本地访问容器

Question

First to be clear, my docker container has an IP address under NetworkSettings.Networks.bridge . That IP is 172.17.0.2

However I cannot access the container via http://172.17.0.2:3000/ after running it with docker run -p 3000:3000 node:8.10.0

My research shows its rough working with docker locally on windows. In following this short guide: https://blog.sixeyed.com/published-ports-on-windows-containers-dont-do-loopback/

I come across using the network NAT IP address. I see this recommended a few places. But that section of my docker inspect does not exist at all. It returns:

As you can see the NAT section is missing entirely. I cant find anything online that mentions why or how to resolve. I was hoping it missing would be a good thing and make it easier to connect. Alas it does not. Any help is appreciated. Here is the dockerfile:

FROM node:8.10.0
WORKDIR /app
COPY package.json /app
RUN npm install
COPY . /app
CMD ["./node_modules/gulp/bin/gulp.js", "assets"]
CMD [ "node", "app.js" ]
EXPOSE 3000

That's a known bug under docker windows. It is fixed in 19.03. So try updating your docker engine.
