ERR_EMPTY_RESPONSE from docker container

I have the same problem using Dockerize GatsbyJS. As Tarun Lalwani's comment above, I resolved the problem by binding or using 0.0.0.0 as hostname

yarn develop -P 0.0.0.0 -p 8000

Adding to the accepted answer: I had the same error message trying to run docker/getting-started.

The problem was that "getting-started" is using port 80 and this was "occupied" (netsh http show urlacl) on my machine.

I had to use docker run -d -p 8888:80 docker/getting-started where 8888 was an unused port. And then open "http://localhost:8888/tutorial/".

Your issue is that you are binding to the 127.0.0.1:8025 inside your code. This makes the code work from inside the container but not outside.

You need to bind to 0.0.0.0:8025 to bind to all interfaces inside the container. So traffic coming from outside of the container is also accepted by your Go app
