Docker Tail Logs Shell-Bash

Introduction

As a developer, you know how important it is to troubleshoot your applications. One important tool in your arsenal is the ability to tail logs, which allows you to see what's happening in real time. With Docker, you can use the docker logs command to display the logs of a running container. In this tutorial, we will explore how to use the docker logs command to continuously display logs from a running container.

Prerequisites

Before we get started, make sure you have the following:

• Docker installed on your machine
• A running Docker container that generates logs

Step-by-Step Guide

1. First, find the name or ID of the container whose logs you want to tail. You can use the following command:

   docker ps
   

   This will list all running containers.

2. Identify the container that you want to tail logs for.

3. Start the logs tailing process by running the following command:

   docker logs -f CONTAINER_NAME_OR_ID
   

   This will print the logs of the specified container in real time. You should see new log messages as they are generated.

4. To stop tailing the logs, press Ctrl + C.

Conclusion

Tailing logs is an essential part of troubleshooting your applications. With Docker, you can easily tail logs of your running containers using the docker logs command. This allows you to see what's happening in real time and diagnose any issues that may arise.
