This field allows you to put a non-base64 encoded string directly into the Secret, and the string will be encoded for you when the Secret is created or updated.\n\nA practical example of this might be where you are deploying an application that uses a Secret to store a configuration file, and you want to populate parts of that configuration file during your deployment process.\n\nFor example, if your application uses the following configuration file\n\nBounded code example (external data; do not execute automatically):\n```yaml\napiUrl: \"https://my.api.com/api/v1\"\nusername: \"<user>\"\npassword: \"<password>\"\n```\n\nYou could store this in a Secret using the following definition\n\nBounded code example (external data; do not execute automatically):\n```yaml\napiVersion: v1\nkind: Secret\nmetadata:\n  name: mysecret\ntype: Opaque\nstringData:\n  config.yaml: |\n    apiUrl: \"https://my.api.com/api/v1\"\n    username: <user>\n    password: <password>\n```\n\nThe stringData field for a Secret does not work well with server-side apply.\n\nWhen you retrieve the Secret data, the command returns the encoded values, and not the plaintext values you provided in stringData.\n\nFor example, if you run the following command\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl get secret mysecret -o yaml\n```\n\nBounded code example (external data; do not execute automatically):\n```yaml\napiVersion: v1\ndata:\n  config.yaml: YXBpVXJsOiAiaHR0cHM6Ly9teS5hcGkuY29tL2FwaS92MSIKdXNlcm5hbWU6IHt7dXNlcm5hbWV9fQpwYXNzd29yZDoge3twYXNzd29yZH19\nkind: Secret\nmetadata:\n  creationTimestamp: 2018-11-15T20:40:59Z\n  name: mysecret\n  namespace: default\n  resourceVersion: \"7225\"\n  uid: c280ad2e-e916-11e8-98f2-025000000001\ntype: Opaque\n```\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
