How to Find the IP Address of a Docker Container

When using Docker containers, you may need to know the IP address of a specific container for debugging, network configuration, or connecting to services running inside the container.

This guide shows how to easily find a Docker container's IP address using simple commands.

Step 1: List Docker containers

First, list all running containers to obtain the container ID or name: docker ps Example output:

$ docker ps
CONTAINER ID   IMAGE                              COMMAND                  CREATED        STATUS        PORTS                                       NAMES
29cf6681b479   bitnami/blackbox-exporter:0.25.0   "/opt/bitnami/blackb…"   17 hours ago   Up 17 hours   0.0.0.0:9115->9115/tcp, :::9115->9115/tcp   blackbox-exporter

Step 2: Inspect the container

Use docker inspect followed by the container ID or name to get detailed information in JSON format, then locate the NetworkSettings section. docker inspect container_id In the JSON output, find the NetworkSettings object.

Step 3: Extract the IP address

Locate the IPAddress field under NetworkSettings. You can also filter the output with a formatted inspect command:

docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_id

Example:

$ docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' 29cf6681b479
172.17.0.2

The command directly prints the container's IP address.
