Hi@akhtar,

In Docker, a secret is any blob of data, such as a password, SSH private key, TLS Certificate, or any other piece of data that is sensitive in nature. When you add a secret to the swarm, Docker sends the secret over to the swarm manager over a mutually authenticated TLS connection, making use of the built-in Certificate Authority that gets automatically created when bootstrapping a new swarm. You can use the below command to create a secret.

$ echo "this is my secret" | docker secret create my_secret
