Labels and Annotations
- Labels go under metadata: in your YAML
- Simple list of
key: valuefor identifying your resource later by selecting, grouping, or filtering for it - Common examples include 'tier: frontend, app: api, env: prod, customer: acme.co'
- Not meant to hold complex, large or non-identifying information, which is what annotations are for
- Filter a get command by label:
kubectl get pods -l app=nginx - Apply only matching labels:
kubectl apply -f myfile.yml -l app=nginx
