Docker and Vite running Getting problem loading page: Failed to load resource: net::ERR_CONNECTION_REFUSED

I. Introduction Docker and Vite are two popular technologies used in modern web development. Docker is a containerization platform that allows developers to build, ship, and run applications in containers. Vite, on the other hand, is a build tool and development server for modern web projects. In this answer, we will discuss the issue of getting a "Failed to load resource: net::ERR_CONNECTION_REFUSED" error when trying to run a Vite application inside a Docker container.

II. Understanding the Problem The "Failed to load resource: net::ERR_CONNECTION_REFUSED" error occurs when the browser is unable to establish a connection to the server where the requested resource is located. In the context of a Vite application running inside a Docker container, this error can occur for several reasons. Some common causes include:

1. Networking issues: The container may not be able to connect to the host network or to external services.
2. Container configuration: The container may not be configured correctly to run the Vite application.
3. Dependency issues: The container may be missing required dependencies for the Vite application to run.

III. Troubleshooting the Problem To troubleshoot the problem of getting a "Failed to load resource: net::ERR_CONNECTION_REFUSED" error when running a Vite application inside a Docker container, follow these steps:

1. Check the container network settings: a. Make sure the container is connected to the host network by checking the Docker network settings. b. If using a custom network, ensure that the container is joined to the network. c. Check the container's IP address by running the command "docker inspect -f '{{range .NetworkSettings.Networks}}{{.Key}}:{{.IPAddress}}{{end}}' <container_name>" in the terminal.

2. Check the container logs: a. Run the command "docker logs <container_name>" to view the container logs and look for any error messages related to networking or Vite.

3. Check the container configuration: a. Ensure that the Dockerfile and package.json files are correctly configured for the Vite application. b. Check that the container has the necessary dependencies installed. c. Make sure that the entrypoint and command in the Dockerfile are set up correctly to run the Vite application.

4. Check for dependency issues: a. Run the command "docker run --rm node:latest npm install" inside the container to install any missing dependencies. b. If using a multi-stage build, ensure that the dependencies are being copied to the final stage of the build.

5. Restart the container: a. If none of the above steps resolve the issue, try restarting the container to see if the problem was temporary.

IV. Conclusion The "Failed to load resource: net::ERR_CONNECTION_REFUSED" error can be a frustrating issue when trying to run a Vite application inside a Docker container. By following the troubleshooting steps outlined above, you can identify and resolve common causes of this error. If the problem persists, consider seeking further assistance from the Docker or Vite community.
