Docker Container port access-CodePudding

I have created an image from an existing dotnet application I can run locally.

in my docker file I have EXPOSE 5000

In the docker compose: ports: [5000:5000]

I start the container using the command: docker run -d -p 5000:5000 --name my-reports my-reports:latest

running the docker ps command :

     NAMES
106c4929c0d6   my-reports:latest   "dotnet my-reports"   8 minutes ago   Up 8 minutes   0.0.0.0:5000->5000/tcp   my-reports

The output of the entrypoint:

      Now listening on: http://localhost:5000

      Application started. Press Ctrl C to shut down.

But I get timeouts trying to access the port from my machine via localhost:5000

CodePudding user response：

You have already provided flag --name my-reports but your container is reporting the name as "vpi-harmony-reports". Do kill the container and re-run the docker command. Also make sure you do not have firewall blocking 5000 port.

CodePudding user response：

Your problem is that your app listens on localhost. This is only available inside the container.

You need to make your app listen on the public network interface. Most easy achieved by using 0.0.0.0 as IP, which makes it listen on all interfaces.

In your case, make the app listen on 0.0.0.0:5000.
