The DB Operator eases the pain of managing PostgreSQL and MySQL instances for applications running in Kubernetes. The Operator creates databases and make them available in the cluster via Custom Resource. It is designed to support the on demand creation of test environments in CI/CD pipelines.

Until we find more maintainers for the project, I (@allanger) only plan to implement features that I personally need and keep the codebase up-to-date. For a couple of years, I’ve been receiving requests for new features related to DbUsers or cloud provider compatibility, but I don’t use either of these.

I don’t want to discourage anyone from creating issues or asking questions. I try to stay active, and I’m always ready to help. If there are bugs or vulnerabilities, they will be fixed as soon as I have time.

However, I want to make it clear that, as of now, I consider the project complete. Even though I have many ideas for improvements, my focus has shifted away from Go and Kubernetes development into a different field.

With that said, if you need a new feature — especially related to DbUsers or cloud providers — feel free to create an issue, but be prepared to implement it yourself. I am always ready to review pull requests.

DB Operator provides following features:

• Create/Delete databases on the database server running outside/inside Kubernetes by creating Database custom resource;
• Create Google Cloud SQL instances by creating DbInstance custom resource;
• Automatically create backup CronJob with defined schedule (limited feature);

• How it works - a general overview and definitions
• Creating Instances - make database instances available for the operator
• Creating Databases - creating databases in those instances
• Enabling regular Backup - and schedule cronjob
• Upgrade guide - breaking changes and guide for the upgrade

The repository contains helm charts for db-operator is moved to https://github.com/db-operator/charts New chart after db-operator > 1.2.7, db-instances > 1.3.0 will be only available in new repository.

Now both DbInstance and Database resources are upgraded to v1beta1. In case you were using connectionStringTemplate, make sure I've migrated to secretsTempaltes before upgrading, because connectionStringTemplate is removed in this version. Everything else should go seamless. We've added Webhooks that will take care of resources with an old API version and convert them to the newer one.

Installing older version of charts is still possible. Check available versions by following command.

$ helm repo add kloeckneri-old https://kloeckner-i.github.io/db-operator/
$ helm search repo kloeckneri-old/ --versions

$ helm repo add db-operator https://db-operator.github.io/charts/
$ helm install --name my-release db-operator/db-operator
