What is the purpose of the "docker network inspect" command?

The primary purpose of the 'docker network inspect' command is to provide detailed information about a specific Docker network.

When you run this command, it displays detailed configuration and status information for one or more networks, including the network ID, name, type (such as bridge or overlay), subnet, gateway, IPAM configuration, and containers connected to the network.

For instance, if you deploy multiple services in a Docker environment that communicate through a specific network, you may need to check the network configuration and operational status to ensure there are no configuration errors or simply to understand which containers are using the network. Using the 'docker network inspect' command provides such detailed information.

Let's consider a concrete example. Suppose we have a Docker network named 'my_network'. You can use the following command to view its details:

bash
docker network inspect my_network

This command outputs all detailed information about the 'my_network' network, including its network ID, configuration, and a list of all containers connected to this network along with their relevant configurations. This information is highly valuable for troubleshooting network issues, conducting audits, and understanding the network topology.
