Binding your application to the database in the Kubernetes cluster

Percona Community

dbaas-operator is Yet Another DBaaS Kubernetes Operator (need to suggest yadbko as a name) that tries to simplify and unify Database Cluster deployments by building a higher abstraction layer on top of Percona Kubernetes Operators.
