In this blog post, I’d like to share some experiences in setting up a Vitess environment for local tests and development on OSX/macOS. As previously, I have presented How To Test and Deploy Kubernetes Operator for MySQL(PXC) in OSX/macOS, this time I will be showing how to Run Vitess on Kubernetes.

The promise of DBaaS like RDS is to reduce operational overhead (among other things) and one of the stellar cases is upgrades (major and minor). The suggested procedure involves just a couple of steps.

• Performs slow shutdown after setting …
