Provide a bit more documentation on how to run the Docker image in HA mode #569
Description
The name timescaledb-docker-ha sounds really promising. The Github page mentions PostgreSQL, Some PostgreSQL extensions, TimescaleDB, pgBackRest, the Dockerfile also lists Patroni and spilo.
What's the intended way to run this image with HA in plain Docker? Should Patroni be used? There was a previous issue "How can I setup timescaledb-ha with patroni", which was closed only with a reference to the Patroni docs. I think that missed the point of the Docker image interworking. How should Patroni be enabled, should the entrypoint be overwritten, or should Patroni be run as command? Any special considerations for Patroni using Timescaledb? Is there an example compose file available?
Or is this not possible anymore after the company announced “Multi-node support is sunsetted”?
