Introduction I frequently have the need to stand-up Kubernetes lab environments for R&D, learning and to develop blogs and solutions, Oracle Cloud Infrastructure (OCI) provides a great wizard to enable the rapid deployment of Oracle Kubernetes Engine (OKE) clusters. However, if you find yourself performing the same task often you should consider automating the process,... Continue Reading →
Background Over the last few years I have shared a number of posts showing how we can deliver Oracle databases on Kubernetes using deployments and statefulsets, on-premises and in the Oracle Cloud.

Oracle Kubernetes Engine (OKE) Cluster Let's start by creating an Oracle Kubernetes Engine cluster on Oracle Cloud Infrastructure (OCI). You can use the OCI Web UI to manually create an OKE Cluster within your OCI Compartment. Or if you prefer you may want to consider using my Terraform automation which is available in GitHub. Before... Continue Reading →
Today there are a number of different MySQL Kubernetes Operators available for use, many providing similar functionality with varying development effort and support offerings, for example Percona, PressLabs, GrdsCloud, Moco to name a few.
