Secrets management in Docker is a critical security concern for any business. When using Docker containers, it is essential to keep sensitive data, such as passwords, API keys, and other credentials, secure.
This article will discuss some best practices for managing secrets in Docker, including how to store them securely and minimize their exposure. We will explore multiple solutions: using Docker Secrets with Docker Swarm, Docker Compose, or Mozilla SOPS. Feel free to choose what’s more appropriate to your use case. But most importantly is to remember to never hard-code your Docker secrets in plain text in your Dockerfile!
