Why We Need To Inspect Docker Network

This JSON output represents information about a Docker network named “nginx.” Let’s break down the details provided in this network inspect output:

[
    {
        "Name": "nginx",
        "Id": "0a1764302adfa32119cc4bc84dd5113f840e50356fe25398eeb7c6efeb18ff7f",
        "Created": "2024-02-23T16:13:02.659550263Z",
        "Scope": "local",
        "Driver": "bridge",
        "EnableIPv6": false,
        "IPAM": {
            "Driver": "default",
            "Options": {},
            "Config": [
                {
                    "Subnet": "172.18.0.0/16",
                    "Gateway": "172.18.0.1"
                }
            ]
        },
        "Internal": false,
        "Attachable": false,
        "Ingress": false,
        "ConfigFrom": {
            "Network": ""
        },
        "ConfigOnly": false,
        "Containers": {},
        "Options": {},
        "Labels": {}
    }
]

To all the following details we will inspect the docker netowrk

• Name: The name of the Docker network is “nginx.”
• Id: The unique identifier (ID) of the Docker network.
• Created: The timestamp indicating when the network was created.
• Scope: The scope of the network (in this case, “local”).
• Driver: The network driver used for this network (in this case, “bridge”).
• EnableIPv6: Indicates whether IPv6 is enabled for the network (in this case, false).
• IPAM: IP Address Management details for the network.
• Driver: The IPAM driver used (in this case, “default”).
• Config: The IP address configuration for the network, including the subnet and gateway.
• Internal: Indicates whether the network is internal (false in this case).
• Attachable: Indicates whether containers outside the network namespace can connect to this network (false in this case).
• Ingress: Indicates whether the network is an “ingress” network (false in this case).
• ConfigFrom: Indicates the source network from which the configuration was taken.
• ConfigOnly: Indicates whether the network is used for configuration only (false in this case).
• Containers: Details about containers connected to this network (empty in this case).
• Options: Additional network options (empty in this case).
• Labels: Labels associated with the network (empty in this case).

“docker network inspection” is the command used in the docker CLI to know the detailed information of a particular docker network. Docker network allows you to inspect the configuration and status of a specific Docker network in which you can find the IP address assigned to the docker network the containers connected and other docker network settings.
