How to Create and Use a Docker Secret From a File In this step-by-step tutorial, learn how to create and use a Docker secret to help keep your data secure.
I will show how to create a secret from a file and then use that secret to deploy a service.
Create the secret file with a command like nano secrets.
Create the secret from the file with a command like docker secret create tr secret /home/jack/secrets.
You can verify the secret was created with the command docker secret inspect tr secret.
The service should deploy using the encrypted secret you created from the file, and that encrypted file will be housed in the container in the /run/secrets/ directory and will have the same name as the secret you created.
