duncan: Docker deployment tool

Duncan is a Docker deployment tool which aims to be like Tim Duncan: consistent, reliable, and un-flashy.

Assumptions

• Duncan manages Kubernetes Deployment or StatefulSet resources (could be extended but this is all that is currently supported now).
• Managed deployments must contain Kubernetes labels that enable the CLI to identify and manage them
• Dynamic configuration is handled via updating environment variables in both Consul (unencrypted) and Vault (encrypted) and are managed with the env and secrets commands respectively
• Dynamic configuration is restricted by Consul and Vault ACL policies (read-only and read-write)
• Deployment is also restricted via Consul ACL
• Docker registry is Quay.io (TODO: add support different options)

Usage:
  duncan [command]

Available Commands:
    config      Search ENV/secrets across all applications
    deploy      Deploy an application
    env         Manage Consul key/values (ENV vars) for an app

    list        List applications
    secrets     Manage Vault secrets (ENV vars) for an app
