How to get a site on localhost from a Docker container on MacOS?

Question

macOS

There is a Nodejs project with a Dockerfile:

FROM node
WORKDIR /var/app
COPY . /var/app
RUN yarn

I built the image and now I run it like this:

docker run -d -p 3000:3000 --name myapp rshaibakov/myapp yarn run dev

Everything seems to be according to the instructions. But how can I access the site in the browser? localhost:3000 says page not found.
Tried setting up proxy as described here . In this case, localhost:3000 says that there is no Internet connection.

Answer 1

Indicated listening to the address 0.0.0.0 in the express and it helped. Thanks again Anton Kucherov for the answer
