Making running production-grade databases easy on Kubernetes

Running production quality database in Kubernetes can be tricky to say the least. In the early days of Kubernetes, replication controllers were used to run a single pod for a database. With the introduction of StatefulSet, it became easy to run a docker container for any database. But what about monitoring, taking periodic backups, restoring from backups or cloning from an existing database? KubeDB is a framework for writing operators for any database that support the following operational requirements:

  • Create a database declaratively using CRD.
  • Take one-off backups or periodic backups to various cloud stores, eg, S3, GCS, Azure etc.
  • Restore from backup or clone any database.
  • Native integration with Prometheus for monitoring via CoreOS Prometheus Operator.
  • Apply deletion lock to avoid accidental deletion of database.
  • Keep track of deleted databases, cleanup prior snapshots with a single command.
  • Use cli to manage databases like kubectl for Kubernetes.

KubeDB is developed at AppsCode to run their SAAS platform on Kubernetes. Currently KubeDB includes support for following datastores:

  • Postgres
  • Elasticsearch
  • Etcd
  • MySQL / MariaDB / Percona Server for MySQL
  • MongoDB
  • Redis
  • Memcached
