Charmed PostgreSQL tutorial

The Charmed PostgreSQL Operator delivers automated operations management from day 0 to day 2 on the PostgreSQL relational database. It is an open source, end-to-end, production-ready data platform on top of Juju. As a first step this tutorial shows you how to get Charmed PostgreSQL up and running, but the tutorial does not stop there. Through this tutorial you will learn a variety of operations, everything from adding replicas to advanced operations such as enabling Transport Layer Security (TLS). In this tutorial we will walk through how to:

• Set up an environment using Multipass with LXD and Juju.
• Deploy PostgreSQL using a single command.
• Access the database directly.
• Add high availability with PostgreSQL Patroni-based cluster.
• Request and change passwords.
• Automatically create PostgreSQL users via Juju relations.
• Reconfigure TLS certificate in one command.

While this tutorial intends to guide and teach you as you deploy Charmed PostgreSQL, it will be most beneficial if you already have a familiarity with:

• Basic terminal commands.
• PostgreSQL concepts such as replication and users.
