How To Automatically Update Running Docker Containers

Docker Containers

Watchtower is a free, open source application that allows you to monitor the running Docker containers and updates them automatically if it finds any changes in their base images. When watchtower finds that a running container needs to be updated, it will gracefully stop the running container by sending it a SIGTERM signal. It will then download the new image, and finally restart the Container with the same options that were used when it was deployed initially. Everything will be done automatically on the background, so the user intervention is not required. In this guide, we will see how to automatically update running Docker containers using Watchtower in Unix-like operating systems.

How Agile, DevOps, and Continuous Integration Changed Software Architecture

You can’t talk about modern software development and testing without bringing up modern techniques and concepts like agile, DevOps, and continuous integration. We’re a fast-twitch industry thanks to the modernization of team and testing dynamics, and that increase in speed has forced other aspects of the process to become equally as malleable and fluid.
