To find out the network your Docker container is connected to, you can use the docker inspect command.
Here’s how you can do it:

First, identify the container ID or name. You can get a list of all running containers using docker ps:

docker ps

Once you have the container ID or name, you can use docker inspect to get detailed information about the container, including its network configuration:

docker inspect <container_id_or_name>

Replace with the ID or name of your container. This command will provide detailed information about the container, including the networks it’s connected to.

In the output of docker inspect, look for the “Networks” section. It will list all the networks the container is connected to, along with details like IP address and network driver.

Alternatively, you can use the following command to get only the network information:

docker inspect --format='{{range $key, $value := .NetworkSettings.Networks}}{{$key}}{{end}}' <container_id_or_name>

This command will directly output the network(s) your container is connected to.
