#GET DOCKER IP HOW TO#

To sum up, in this article, we discussed how to retrieve the IP addresses of one or all containers in a host machine or a compose network using 6 different methods. Lastly, take a look at the docker network inspect details to view the metadata of the network mcv1 you created: 1. Or get the gateway for the last container started: docker inspect (docker ps -q) grep Gateway. You may also use grep command to get just the lines matching the string 'IPAddress'. Get the IP of the most recently started container: docker inspect (docker ps -q) grep IPAddress. Go towards the end and look into the Networks section to get the containers IP address. ) | sed 's#%tab%# #g' | sed 's#/#g' | sort -t. The inspect command gives you many details about the container you are inspecting. The first method is using the Docker inspect command to inspect containers and using the format option to print out the IP address of the container only. Using the Inspect Command along with Format Option In this article, we will discuss some easy and frequently used methods to do so. There are several methods to get the IP address of a container from the host machine. This will list all the existing containers. You can get the container names using the ' Docker ps -a' command. You can easily get the IP address of any container if you have the name or ID of the container. And each network is created with a default subnet mask, using it as a pool later on to give away the IP addresses. By default, the container is assigned an IP address for every Docker network it connects to. For this, you need to have the IP addresses of the containers. We will ignore the other two, and use the bridge network when we get to the examples.

You might need to ping these containers periodically to check their status. In such a case, determining which container is actively running and which has failed, is very difficult. Moreover, if you are on a network or using compose, there might be several containers running inside the network. At times, it becomes really difficult to keep track of all these containers. If you are working with Docker for a long time now, you might already have lots of containers running in your host machine.
