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:

   tau --defaults --yes json current
   

2. Remote mode:

   tau select cloud --fqdn <cloud_fqdn>
   tau --defaults --yes json current
   

   • If the next operation includes tau clear application, immediately re-check context and re-select remote FQDN if drifted:

     tau --defaults --yes clear application
     tau --defaults --yes json current
     tau --defaults --yes select cloud --fqdn <cloud_fqdn>
     

3. Dream default mode:

   dream status universe default
   

4. If Dream status fails or not running:

   # If you have newer Dream:
   dream start
   # If you have stable/older Dream (no `dream start`):
   dream new multiverse --daemon --universes default
   dream new universe default
   dream status universe default
   

5. Select Dream cloud:

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

Remote context hard check

• For any remote mutation (tau push, tau import, tau new domain --generated-fqdn, tau delete domain), context must show:
  • Cloud Type: remote
  • Cloud: <cloud_fqdn>
• If not, stop and re-select the cloud before proceeding.

Dream readiness protocol

1. Confirm Dream is reachable (dream status universe default).
2. If unavailable, start Dream:
   • Newer Dream: dream start
   • Stable/older Dream: dream new multiverse --daemon --universes default Then 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:

  docker info
  

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