If you’re running Postgres in Kubernetes, you’ve probably wondered if Postgres is natively Kubernetes friendly. Portworx: Kubegres is available as open source. In this article, we’ll look at Postgres’ native Kubernetes support’s basics and show why you should choose it instead of another database. Once you’ve done that, you’ll be on your way to a successful deployment.
Postgres operator for Kubernetes
The Postgres operator for Kubernetes is a tool for managing and deploying Postgres instances. It interacts with a YAML-formatted configuration file, called a Kubernetes manifest, to send instructions to Postgres instance instances. Postgres instance management requires an operator to maintain the state of the database. This tool has two primary purposes: provisioning databases, providing high availability, and keeping updates rolling.
Postgres operator for Kubernetes is a free, open-source tool that helps you manage PostgreSQL workloads in a containerized environment. It adheres to DevOps principles such as declarative configuration and immutable infrastructure. Additionally, it can co-exist in the same namespace as other Kubernetes instances. In addition, it can run on top of existing clusters, so users can easily move them to different cases if needed.
You can install a Postgres operator for Kubernetes using either the Tanzu Network Registry or the Downloadable Archive File. However, it is recommended to use the latter if your servers aren’t connected to the internet and/or have private registry installations. You can also install Postgres operators for Kubernetes using kubectl. The Postgres operator for Kubernetes meets the base-level threshold for high availability.
Postgres as a native Kubernetes database
As a native Kubernetes database, Postgres provides numerous benefits over other databases. Its stateless nature is improved by its support for transactional DDL, JSON data, schemas, stored functions, and optimized column additions. The reasons for choosing Postgres over other databases are mostly technical and depend on the persona you’re trying to appeal to. While application developers may like Postgres for its ability to handle relational and unstructured data, a Kubernetes administrator might be tempted by the declarative configuration and immutability of the selected Postgres operator.
Cloud Native PostgreSQL aims to meet the needs of Kubernetes applications and is distributed by EnterpriseDB. Postgres as a native Kubernetes database is useful for any application developer who needs to run their software against a PostgreSQL database. Cloud Native Postgres is 100% open source and community-driven. It inherits PostgreSQL’s security infrastructure.
CloudNativePG from EDB is the first open-source operator optimized for Kubernetes. It supports cloud-native principles, enabling senior IT decision makers to design and implement a microservices-based cloud-native architecture using Postgres. CloudNativePG speeds application, service, and enterprise innovation. The underlying Postgres operator enables Postgres instances to collaborate with Kubernetes pods.
Postgres as a Kubernetes-friendly database
You’ve probably heard of Postgres if you’re looking for a reliable, efficient database for your Kubernetes-based applications. A simple and straightforward Postgres database can make the job easier for DevOps teams. However, while Postgres is an excellent choice for a Kubernetes-friendly database, you should look at the other options. While Postgres is easy to install, it still requires some monitoring, logging, and auditing side tools. You should also consider Postgres’s maturity level in cloud-native databases.
A Kubernetes-friendly database must provide the necessary features. Pods are mortal, and the likelihood of failure is greater than traditional databases. A database with features like failover elections, replication, and sharding is more compatible with Kubernetes. Some open source projects even offer operators and custom resources for managing the database. Postgres is an excellent option for microservice databases.
Postgres provides an open-source database operator, PGO, which automates the maintenance of databases on Kubernetes. Postgres operators enable users to deploy Kubernetes native applications on Postgres. Operators provide centralized administrations and automation at scale. The PGO works with any supported Kubernetes storage system, including Hostpath. You should use the right one for your workload since Postgres has various storage options.
