I have a server (debian 11) on which there is a psql container, with an existing database. My number of customers is increasing day by day, so I plan for the future and want to make my server flexible in order to increase my performance according the number of customers.
I therefore wish, over time to deploy several new machines on which I would deploy other psql containers which will have to work in collaboration (load balacing etc ...)
So I have now deployed a new machine on which I have installed a blank psql container. What are the steps that I must follow so that this new database is synchronized with my existing database, and can collaborate together?
I have already followed several tutorials found on the web but unfortunately I am a little lost. Some people talk about pgpool-II, others only talk about replication. I tried to do a replication but unfortunately I can't do it in docker
