Charmed PostgreSQL K8s tutorial
The Charmed PostgreSQL K8s 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 K8s 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 MicroK8s 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 K8s, it will be most beneficial if you already have a familiarity with:
- Basic terminal commands.
- PostgreSQL concepts such as replication and users.
