Development Server Not Accessible Outside Docker Container

[Sajith-K-Sasi]

I'm encountering an issue where the Vue.js development server, running inside a Docker container, is not accessible from outside the container. This problem occurs when the development environment set up inside a Docker container using Visual Studio Code.

Steps to Reproduce:

1. Set up a Frappe application using Docker for development. frappe docker
2. Create a Vue.js application inside the Frappe app using Doppio.
   bench add-spa
3. Run the Vue.js application in development mode within the Docker container.
   yarn dev or npm run dev
4. Attempt to access the Vue.js application from the host machine or external network.

Expected Behavior:

The Vue.js development server should be accessible from the host machine, allowing for testing and development outside the Docker container.

Actual Behavior:

The Vue.js development server is not accessible from outside the Docker container.
