These are currently random notes and are not much help to anybody yet. They will get tidied as I add to the page.

Docker Swarm

From inside a docker swarm manager node, there are two ways of creating a secret.

Using a string value:

printf <your_secret_value> | docker secret create your_secret_key -

Using a file path:

docker secret create your_secret_key ./your_secret_value.json

Docker swarm secrets are saved, encrypted, and are accessible to containers via a filepath:

/run/secrets/your_secret_key.
