Kubernetes Secret Generator

Paste a .env file and instantly generate a ready-to-apply Kubernetes Secret manifest with Base64-encoded data — 100% in your browser.

How to create a Kubernetes Secret

From .env to an applyable Secret manifest in four steps.

  1. 1

    Paste your .env file

    Drop your environment variables into the generator. It handles comments, quoted values, and standard .env syntax.

  2. 2

    Set the metadata

    Choose the Secret name and an optional namespace. The manifest preview updates in real time.

  3. 3

    Copy the manifest

    The generated YAML is Base64-encoded and ready for production. Copy it with one click or download secret.yaml.

  4. 4

    Store source secrets in Envless

    Manage the underlying values end-to-end encrypted in Envless so your team can rotate and audit access without plaintext exposure.

Why use the Envless Kubernetes Secret generator?

Production-correct Secret YAML from a team focused on secret management.

Base64-encoded data fields

Encodes each variable under the data: section — the production-standard format kubectl apply expects, not the plaintext stringData: shortcut.

Configurable name and namespace

Set your own metadata.name and an optional namespace. The manifest preview updates live so you see exactly what will be applied to your cluster.

100% client-side generation

Your .env file never leaves your browser. No uploads, no logging, no network calls — parsing and encoding happen entirely on your device.

Copy and apply immediately

The generated YAML is ready to use. Copy it and pipe to kubectl apply -f -, or download it and commit it to your deployment config.

Kubernetes Secret FAQ

Everything you need to know about turning a .env into a Kubernetes Secret.

No. The generator runs 100% in your browser. Your .env file never leaves your device — there are no uploads, no logging, and no network requests.

The data: field uses Base64 encoding, which is the standard Kubernetes Secret format that kubectl apply and most tooling expect. stringData: is plaintext and not recommended for production manifests.

Yes. The generator lets you configure the Secret name and an optional namespace, and both appear in the live preview so you can verify before copying.

They are handled correctly. Base64 encoding preserves special characters, newlines, and Unicode, and they decode properly when Kubernetes reads the Secret.

Neither. The generator is completely free with no rate limits and no sign-up. Generate as many manifests as you need.

Use Envless to store and share the source .env values end-to-end encrypted, so your team can manage, rotate, and audit access without seeing plaintext or pasting it into chat.
