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 period backups to various cloud stores, eg, S3, GCS, 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 we include complete implementations for Postgres and ElasticSearch database.
Please pick a version of KubeDB that matches your Kubernetes installation.
