Labels and Annotations

  • 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
