[Solved] From inside of a Docker container, how do I connect to the localhost of the machine?

To connect to the localhost of the machine from inside a Docker container, you can use the host.docker.internal hostname. This special DNS name is resolved to the internal IP address used by the host.

For example, if you want to connect to a service running on the host machine's localhost on port 8080, you can use the following command from inside the container: 

curl http://host.docker.internal:8080

Note that this method of connecting to the host's localhost will only work if you are using Docker for Mac or Docker for Windows. If you are using Docker on a different operating system, you will need to use the IP address of the host machine instead.

You can also use the --network host flag when starting the container to allow it to connect directly to the host's network interfaces. For example:

 docker run --network host <image-name>  

This can be useful if you need to connect to a service running on the host that is not exposed on localhost, or if you need to bind to a specific IP address or port on the host.
