[Kubernetes] Three Management Approaches
- Three Management Approaches
- Imperative commands: run, expose, scale, edit, create deployment
- Best for dev/learning/personal projects
- Easy to learn, hardest to manage over time
- Imperative objects: create -f file.yml, replace -f file.yml, delete...
- Good for prod of small environments, single file per command
- Store your changes in git-based yaml files
- Hard to automate
- Declarative objects: apply -f file.yml or dir\, diff
- Best for prod, easier to automate
- Harder to understand and predict changes
- Most Important Rule:
- Don't mix the three approaches
- Bret's recommendations:
- Learn the Imperative CLI for easy control of local and test setups
- Move to apply -f file.yml and apply -f directory\ for prod
- Store yaml in git, git commit each change before you apply
- This trains you for later doing GitOps (where git commits are automatically applied to clusters)
- End
