Root Cause

A Docker service or Compose stack references a secret that does not exist in the swarm or has not been created. Secrets must be created before services that use them.

generic

Workarounds

  1. 95% success Create the secret before deploying the service 
    echo 'secret_value' | docker secret create secret_name - (for Swarm) or define in docker-compose.yml with file: ./secret.txt (for Compose)

    Sources: https://docs.docker.com/engine/swarm/secrets/

  2. 90% success For Docker Compose, define secrets as file-based in the compose file 
    In docker-compose.yml: secrets: { my_secret: { file: ./my_secret.txt } } and reference in services with secrets: [my_secret]

    Sources: https://docs.docker.com/compose/how-tos/use-secrets/

Dead Ends

Common approaches that don't work:

  1. Hardcoding the secret value in the Dockerfile or docker-compose.yml 90% fail

    Secrets end up in the image layer history or version control, creating a security vulnerability

  2. Using environment variables instead of Docker secrets for sensitive data 60% fail

    Environment variables are visible in docker inspect, /proc/<pid>/environ, and logs; less secure than secrets
