Example "Multi Tenancy Frontend Operator"

The operator simply deploys a frontend application which runs on a nginx server. Therefor the operator creates following Kubernetes resources:

• A deployment
• A service
• Some secrets

The source code of the example frontend application is available in the open sourced GitHub project multi-tenancy-frontend.

The project is related to following blog posts:

LOCAL DEVELOPMENT

Get the operator running on a local machine and using Kubernetes. I verified my example project (Multi Tenancy Frontend Operator) also for these topics and it worked for me.

• Install the Operator SDK on macOS
• Develop a simple operator locally
• Debug a GO operator
• Run an operator as a deployment

USING THE OPERATOR LIFECYCLE MANAGER (OLM)

I verified my example project (Multi Tenancy Frontend Operator) also for these topics and it worked for me:

• How to create a bundle?
• Run the bundle with an Operator Lifecycle Manager (OLM)
• Deploy an operator without the Operator SDK
• Add a new API version to an existing operator
• Add a conversion webhook to an operator to convert API versions

MONITORING

• Monitor your custom operator with Prometheus
• Example for an installation and an initial configuration of the Grafana operator
• Access Prometheus queries using the Prometheus HTTP API
