# The DB-consumer chain a single node cannot host, proved across two machines.
|
||
#
|
||
# The app-postgres provider and the mesh's own foundation store both want host port 5432, so they
|
||
# cannot share a machine — the collision that blocked this chain single-node. Here the foundation
|
||
# (store, broker, control) lives on `anchor` and NOTHING else; `laptop` runs the whole chain —
|
||
# the baserow and letta CONSUMERS of the one store (baserow keeps its cache inside its own container,
|
||
# novox/hq 081). Both
|
||
# machines sit on one shared segment and enrol into the one mesh; only enrolment crosses to anchor,
|
||
# over the underlay both machines already share. The consumers' databases are minted on the one
|
||
# foundation store on anchor and reached over the overlay; laptop runs no provider of its own.
