Passing application configuration information as environmental variables was once considered best practice in 12 factor applications. However, this practice can expose information in logs, can be difficult to track how and when information is exposed, third party applications can access this information.

Secrets are a way to keep information such as passwords and credentials secure in a Docker CE or EE with swarm mode. Docker manages secrets and securely transmits it to only those nodes in the swarm that need access to it. Secrets are encrypted during transit and at rest in a Docker swarm. A secret is only accessible to those services which have been granted explicit access to it, and only while those service tasks are running.
