Kubernetes Operators extend Kubernetes to run stateful services and applications as native Kubernetes resources. Today one can find an Operator for almost every kind of stateful service/application to run on Kubernetes - MySQL, Postgres, Spark, ElasticSearch, Wordpress, Moodle, Backup/Restore, SSL Certificate Management, etc. Several questions arise when using multiple Operators together to build a platform stack - How to discover capabilities of each Operator? Will different Operators/Custom Resources interoperate correctly? If not, what is required for their interoperability? How to get consistent experience across multiple Operators?
We have developed a novel approach to address these unique challenges around building platforms assembled from multiple Kubernetes Operators. We term this approach as - ‘Platform-as-Code’ (https://cloudark.io/platform-as-code). Platform-as-Code is the process of aggregating multiple Kubernetes Operators for the purpose of creating and managing platforms declaratively using native Kubernetes interfaces.
The talk will present the Platform-as-Code approach and discuss our learnings around Kubernetes Operators in relation to this approach.
We will also demo a platformization use-case using our open source KubePlus Platform Toolkit (https://github.com/cloud-ark/kubeplus).
