A secret is a file that contains sensitive data, such as a password.
Let's say the docker secret ls command returns the following.
ID NAME DRIVER CREATED UPDATED pp6d206pqk28cj12kjv36l2v7 my_secret 14 months ago 14 months ago g6ab3l6qr9w5lt8puu3f971f5 foobar 7 months ago 7 months ago oxp56zzcssvptzdk214qv22l5 another_example 5 months ago 5 months ago
The docker secret rm command will delete a secret. In this example, the secret with ID pp6d206pqk28cj12kjv36l2v7 is deleted.
docker secret rm pp6d206pqk28cj12kjv36l2v7
In this example, the secret named my_secret is deleted.
docker secret rm my_secret
