# Redundant OPC UA server set — one compose file, topology chosen from the environment.
|
|
#
|
|
# Pick the topology by setting HA_MODE / HA_CONSISTENCY (and REDUNDANCY_MODE) either
|
|
# inline or with --env-file. Three built-in topologies, each has a ready-made env file:
|
|
#
|
|
# * active/active, eventual consistency (CRDT gossip) — DEFAULT
|
|
# --env-file samples/RedundantServer/active-active-eventual.env
|
|
# * active/active, strong consistency (Raft)
|
|
# --env-file samples/RedundantServer/active-active-strong.env
|
|
# * active/passive, strong consistency (Raft)
|
|
# --env-file samples/RedundantServer/active-passive.env
|
|
#
|
|
# Three server replicas run in every topology (Raft needs 3 for a fault-tolerant quorum;
|
|
# active/active eventual works with 2 or 3 — remove server-c for a 2-node run). The
|
|
# replica count is therefore configurable by dropping/adding server-c.
|
|
#
|
|
# The build context is the repository root. Run from the repo root, e.g. active/passive:
|
|
# docker compose --env-file samples/RedundantServer/active-passive.env \
|
|
# -f samples/RedundantServer/docker-compose.yml up --build
|
|
#
|
|
# OPC UA endpoints on the host: replica-a opc.tcp://localhost:62543/RedundantServer,
|
|
# replica-b :62544, replica-c :62545. The Raft transport (6560) and CRDT gossip (4840)
|
|
# stay on the internal network and are addressed by container DNS.
|
|
#
|
|
# The transparent (nginx virtual endpoint) and GetEndpoints load-direction demos have
|
|
# their own folders: Transparent/docker-compose.yml and LoadDirection/docker-compose.yml.
