Rotating Docker Swarm Secrets with Ansible

Summary

In this article, I guide you through the process of effectively rotating Docker Swarm secrets using Ansible. As you know, Docker Swarm secrets are immutable, so you will learn how to automate secret management in a Docker Swarm environment. This involves implementing an Ansible role for secret rotation, covering checksum calculations, creating new secrets, updating Docker Compose files, and cleaning up unused secrets.

Following this guide will give you a convenient solution to update Docker secrets and force the application to be redeployed with the latest secrets efficiently.
