Unleash the potential of ‘kubectl --watch’, ‘jq’, and ‘bash’ as you hack your own Kubernetes controllers directly from your terminal, addressing the DevOps solution gaps without relying on kopf, Go, or controller-runtime. Through hands-on demos, you will learn how ‘kubectl’, probably already at your disposal, can be harnessed to automate tasks such as transforming Secrets without init containers, synchronizing resources to another cluster, or pre-provisioning ExternalSecrets.

After attending this talk, you will feel comfortable with the concepts of reconciliation loop, desired state and observed state. Not only will you be able to discern the differences between operators and controllers, but you will also comprehend the trade-offs and alternatives to devising your own bespoke Bash controller. Prepare for a dive into the core Kubernetes’ controller model!
