Lines beginning with a '#' will be ignored, # and an empty file will abort the edit. If an error occurs while saving this file will be # reopened with the relevant failures. # apiVersion: v1 data: username: YWRtaW4= password: MWYyZDFlMmU2N2Rm kind: Secret metadata: annotations: kubectl.kubernetes.io/last-applied-configuration: { ... } creationTimestamp: 2016-01-22T18:41:56Z name: mysecret namespace: default resourceVersion: "164619" uid: cfee02d6-c137-11e5-8d73-42010af00002 type: Opaque ```
