# GetEndpoints load direction over a strongly-consistent (Raft) redundant set.
|
|
#
|
|
# Builds on the active/passive topology (docker-compose.yml with active-passive.env): a 3-node RaftCs cluster forms the shared, linearizable
|
|
# store that the load-direction signals (each replica's health ServiceLevel, load weight, and
|
|
# endpoints) are published to and read from across containers. HA_BALANCING_URL enables the
|
|
# GetEndpoints director on every replica: a GetEndpoints request arriving on that virtual
|
|
# discovery URL is answered with the best replica's endpoints (the active writer in this
|
|
# active/passive set), while plain discovery on a replica's own URL is unaffected.
|
|
#
|
|
# In a real deployment a load balancer / Kubernetes Service fronts the replicas at
|
|
# HA_BALANCING_URL and forwards the discovery request to any replica; this compose sets the
|
|
# variable to illustrate the server-side wiring (there is no LB container here, so point a
|
|
# client at a replica's own URL to observe normal discovery, and use HA_BALANCING_URL as the
|
|
# address your LB/Service would expose).
|
|
#
|
|
# The build context is the repository root. Run from the repo root:
|
|
# docker compose -f samples/RedundantServer/LoadDirection/docker-compose.yml up --build
