For a real-world example, continue to Intermediate example: Use secrets with a Nginx service.\n\nAdd a secret to Docker. The docker secret create command reads standard input because the last argument, which represents the file to read the secret from, is set to -.\n\nBounded code example (external data; do not execute automatically):\n```console\n    $ printf \"This is a secret\" | docker secret create my_secret_data -\n```\n\nCreate a redis service and grant it access to the secret. By default, the container can access the secret at /run/secrets/, but you can customize the file name on the container using the target option.\n\nBounded code example (external data; do not execute automatically):\n```console\n    $ docker service  create --name redis --secret my_secret_data redis:alpine\n```\n\nVerify that the task is running without issues using docker service ps. If everything is working, the output looks similar to this\n\nBounded code example (external data; do not execute automatically):\n```console\n    $ docker service ps redis\n\n    ID            NAME     IMAGE         NODE              DESIRED STATE  CURRENT STATE          ERROR  PORTS\n    bkna6bpn8r1a  redis.1  redis:alpine  ip-172-31-46-109  Running        Running 8 seconds ago\n```\n\nBounded code example (external data; do not execute automatically):\n```console\n    $ docker service ps redis\n\n    NAME                      IMAGE         NODE  DESIRED STATE  CURRENT STATE          ERROR                      PORTS\n    redis.1.siftice35gla      redis:alpine  moby  Running        Running 4 seconds ago\n     \\_ redis.1.whum5b7gu13e  redis:alpine  moby  Shutdown       Failed 20 seconds ago      \"task: non-zero exit (1)\"\n     \\_ redis.1.2s6yorvd9zow  redis:alpine  moby  Shutdown       Failed 56 seconds ago      \"task: non-zero exit (1)\"\n     \\_ redis.1.ulfzrcyaf6pg  redis:alpine  moby  Shutdown       Failed about a minute ago  \"task: non-zero exit (1)\"\n     \\_ redis.1.wrny5v4xyps6  redis:alpine  moby  Shutdown       Failed 2 minutes ago       \"task: non-zero exit (1)\"\n``` …\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
