Decrypt secrets via protocol handler

On Windows, the command helm secrets patch windows needs to be run first.

helm upgrade name . -f secrets://secrets.yaml

See Usage for more information

Decrypt secrets via plugin command

Wraps the whole helm command. Slow on multiple value files.

helm secrets upgrade name . -f secrets.yaml

helm-secrets supports evaluating vals expressions inside Helm templates by enable the flag --evaluate-templates.


apiVersion: v1

  name: secret
type: Opaque
  password: "ref+awsssm://foo/bar?mode=singleparam#/BAR"


helm secrets --evaluate-templates upgrade name .

Cloud support

Use AWS Secrets Manager or Azure KeyVault for storing secrets securely and reference them inside values.yaml

helm secrets --backend vals template bitnami/mysql --name-template mysql \
  --set auth.rootPassword=ref+awsssm://foo/bar?mode=singleparam#/BAR

See Cloud Integration for more information.

Terraform support

The Terraform Helm provider does not support downloader plugins.

helm-secrets can be used together with the Terraform external data source provider.


data "external" "helm-secrets" {
  program = ["helm", "secrets", "decrypt", "--terraform", "../../examples/sops/secrets.yaml"]

resource "helm_release" "example" {

  values = [

An example of how to use helm-secrets with Terraform could be found in examples/terraform.

Secret backends

helm-secrets support multiple secret backends. Currently, sops and vals are supported.

See Secret-Backends how to use them.
