CRD's and The Operator Pattern
- You can add 3rd-party Resources and Controllers
- This extends Kubernetes API and CLI
- A pattern is starting to emerge of using these together
- Operator: automate deployment and management of complex apps, e.g. Databases, monitoring tools, backups, and custom ingresses
- All out
kubectlcommands just talk to the Kubernetes API - Kubernetes has limited built-in templating, versioning, tracking and management of your apps
- There are now many tools to do that, but many are defunct
- Helm is the most popular
- 'Compose on Kubernetes' comes with Docker Desktop
- These are optional, and your distro may have a preference
- Most distros support Helm
- Many of the deployment tools have templating options
- You'll need a solution as a number of environments / apps grow
- Helm was the first 'winner' in this space, but can be complex
