KubeDB – Run production-grade databases easily on Kubernetes
While I have completely embraced running stateless services in Docker, I have been hesitant to migrate the database layer to containers.  While I have not tested it personally, I have seen numerous reports of performance issues when using volumes.  Is this no longer an issue, or was it limited to bind mounts?  Do volumes not use the storage driver?  Also, I have run into permission issues when using volumes with Docker, which I&#x27;m sure was just my own ignorance but it does seem like a cause for confusion and potential error.  I have read through the documentation on the linked page, and the quickstart guides for KubeDB seems great for getting up and running, but I do worry about situations like if an automated PG database failover can&#x27;t reconcile a timeline, there isn&#x27;t much documentation on failover at all and this could add significant complexity to something that is already a potential nightmare.  Anyone care to share their experiences running production databases in k8s?
