Cloud Selection

Rule

• If user provides FQDN -> remote cloud.
• If no FQDN provided -> Dream local by default.
• For Dream/local, do not run backend-contacting

  tau

  commands until Dream/universe readiness is confirmed.

Steps

1. Inspect:
   bash

   tau --json current

2. Remote mode:
   bash

   tau select cloud --fqdn <cloud_fqdn>

3. Dream default mode:
   bash

   dream status universe default

4. If Dream status fails or not running:
   bash

   dream start
   dream new universe default
   dream status universe default

5. Select Dream cloud:
   bash

   tau select cloud --universe default
   tau --json current

Dream readiness protocol

1. Confirm Dream is reachable (

   dream status universe default

   ).
2. If unavailable, start Dream and create/select

   default

   universe.
3. Only after readiness is confirmed, continue with list/query/select operations that contact backend services.

Dream deployment prerequisites (local)

• Before

  dream inject push-all

  /

  push-specific

  , ensure Docker is running:
  bash

  docker info

• If Docker is not available on Windows, start Docker Desktop and re-check.
• Record Dream/Docker readiness state in

  taubyte-context-log

  .
