Generate a Kubernetes Secret
A Kubernetes Secret stores sensitive data such as passwords, API keys and tokens, and its values must be base64-encoded in the manifest. This generator builds a complete Secret YAML from your key-value pairs, automatically base64-encoding each value as Kubernetes requires. You provide a name, a namespace and the sensitive data as simple key=value lines, and the tool produces a ready-to-apply manifest of type Opaque.
The base64 encoding is handled for you, avoiding the common mistake of pasting raw, unencoded values.
Handling secrets in Kubernetes
Secrets decouple sensitive configuration from your application images and pods, letting you mount them as files or inject them as environment variables. Remember that base64 is encoding, not encryption: anyone with access to the manifest can decode the values, so Secret YAML should be treated as sensitive and kept out of public version control. For stronger protection, Kubernetes can encrypt secrets at rest and integrate with external secret managers.
Because this tool runs entirely in your browser, your secret values are never uploaded. Still, handle the generated manifest carefully and apply it only to trusted clusters.
Notes on the output
Because the kubernetes secret generator runs entirely in your browser, you can adjust every option and see the generated output update instantly, with nothing uploaded and no sign-up needed. The result is clean, standard configuration you can paste straight into your project and refine by hand, and because the processing is local, even sensitive values stay private on your own machine.

Frequently Asked Questions
Why are Secret values base64-encoded?
Kubernetes requires the data field of a Secret to be base64-encoded. The generator does this automatically for each value you enter.
Is base64 encoding secure?
No. It is reversible encoding, not encryption. Anyone with the manifest can decode the values, so treat Secret YAML as sensitive.
Are my secret values uploaded?
No. Encoding happens entirely in your browser, so your sensitive values never leave your device.
How do I use the Secret in a pod?
Reference it as environment variables with valueFrom secretKeyRef, or mount it as files via a volume, in your pod or deployment spec.
Privacy & Security
Everything runs in your browser; nothing is uploaded.
