Labels and Annotations

Search…

Labels go under metadata: in your YAML
Simple list of key: value for 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
