While searching for a simple Postgres cluster solution using Docker, I came across timescaledb-docker-ha. But I didn’t find any documentation or tutorial how to setup a 3 server cluster using the Docker image.
I expected it to be a simple etcd and timescaledb-ha Docker compose file with some env vars, maybe a Patroni config, run on all 3 nodes. But none of the chatbots and LLMs could deliver a working version.
HOST = db-1.internal # per node
HOST_IP = 100.64.0.1 # per node
HOST_1 = db-1.internal
HOST_2 = db-2.internal
HOST_3 = db-3.internal
Is there any documentation or tutorial available, preferably with synchronous replication?
