Table: docker_network - Query Docker Networks using SQL

Docker Networks are a crucial component in Docker's architecture, enabling containers to communicate with each other and with outside networks. They are designed to facilitate network isolation and service discovery, which are essential for microservice architectures. Docker Networks also provide the flexibility to design and implement networking that fits a more complex application architecture.

Table Usage Guide

The docker_network table offers insights into Docker Networks. Network administrators and DevOps engineers can utilize this table to obtain detailed information about Docker Networks, including their configuration, options, and the services running on them. This information can be valuable for troubleshooting network issues, optimizing network performance, and ensuring network security.

Examples

List all networks

Explore all the networks within your Docker environment. This can help in understanding the connectivity and isolation of your containers, aiding in better network management and security.

Schema for docker_network

Name	Type	Description
_ctx	jsonb	Steampipe context in JSON form, e.g. connection_name.
attachable	boolean	True if if the global scope is manually attachable by regular containers from workers in swarm mode.
config_from	jsonb	Source which will provide the configuration for this network.
config_only	boolean	True if the network is a place-holder for configuration of other networks only.
containers	jsonb	Endpoints belonging to the network.
created	timestamp with time zone	Time when the network was created.
driver	text	Driver is the Driver name used to create the network (e.g. 'bridge', 'overlay').
enable_ipv6	boolean	True if IPv6 is enabled.
id	text	ID of the network.
ingress	boolean	True if the network is providing the routing-mesh for the swarm cluster.
internal	boolean	True if if the network is used internal only.
ipam	jsonb	Network IP address management.
labels	jsonb	Metadata specific to the network.
name	text	Name of the network.
options	jsonb	Network specific options to use for when creating the network.
peers	jsonb	Peer nodes for an overlay network.
scope	text	Scope describes the level at which the network exists (e.g. 'swarm' for cluster-wide or 'local' for machine level).
services	jsonb	Services in the network.

Export

This table is available as a standalone Exporter CLI. Steampipe exporters are stand-alone binaries that allow you to extract data using Steampipe plugins without a database.

You can download the tarball for your platform from the Releases page, but it is simplest to install them with the steampipe_export_installer.sh script:

/bin/sh -c "$(curl -fsSL https://steampipe.io/install/export.sh)" -- docker

You can pass the configuration to the command with the --config argument:

steampipe_export_docker --config '<your_config>' docker_network
