💡 Hint

Common Mistakes

Using 'Name' or 'ID' instead of 'IPv4Address' will not show the IP address.

The --format option uses Go templates. To get the IP address of container 'abc123', use .Containers.abc123.IPv4Address.

💡 Hint

Common Mistakes

Using 'Config' instead of 'HostConfig' will not find NetworkMode.

Using wrong container name will cause error.

The network mode is found under HostConfig.NetworkMode in the container's inspect data. The container name is 'webapp'.
