External Secrets

---

The External Secrets Operator reads information from a third party service like AWS Secrets Manager and automatically injects the values as Kubernetes Secrets.

Multiple people and organizations are joining efforts to create a single External Secrets solution based on existing projects. If you are curious about the origins of this project, check out this issue and this PR.

Supported Backends

• AWS Secrets Manager
• AWS Parameter Store
• Hashicorp Vault
• Google Cloud Secrets Manager
• Azure Key Vault

ESO installation with an AWS example

If you want to use Helm:

helm repo add external-secrets https://charts.external-secrets.io

helm install external-secrets \
   external-secrets/external-secrets \
    -n external-secrets \
    --create-namespace \
  # --set installCRDs=true

If you want to run it locally against the active Kubernetes cluster context:

git clone https://github.com/external-secrets/external-secrets.git
make crds.install
make run

Create a secret containing your AWS credentials:

echo -n 'KEYID' > ./access-key
echo -n 'SECRETKEY' > ./secret-access-key
kubectl create secret generic awssm-secret --from-file=./access-key  --from-file=./secret-access-key

Create a secret inside AWS Secret Manager with name my-json-secret with the following data:

{
  "name": {"first": "Tom", "last": "Anderson"},
  "friends": [
    {"first": "Dale", "last": "Murphy"},
    {"first": "Roger", "last": "Craig"},
    {"first": "Jane", "last": "Murphy"}
  ]
}

Apply the sample resources (omitting role and controller keys here, you should not omit them in production):

# secretstore.yaml
apiVersion: external-secrets.io/v1alpha1
kind: SecretStore
metadata:
  name: secretstore-sample
spec:
  provider:
    aws:
      service: SecretsManager
      region: us-east-2
      auth:
        secretRef:
          accessKeyIDSecretRef:
            name: awssm-secret
            key: access-key
          secretAccessKeySecretRef:
            name: awssm-secret
            key: secret-access-key

# externalsecret.yaml
apiVersion: external-secrets.io/v1alpha1
kind: ExternalSecret
metadata:
  name: example
spec:
  refreshInterval: 1m
  secretStoreRef:
    name: secretstore-sample
    kind: SecretStore
  target:
    name: secret-to-be-created
    creationPolicy: Owner
  data:
  - secretKey: firstname
    remoteRef:
      key: my-json-secret
      property: name.first # Tom
  - secretKey: first_friend
    remoteRef:
      key: my-json-secret
      property: friends.1.first # Roger

kubectl apply -f secretstore.yaml
kubectl apply -f externalsecret.yaml

Running kubectl get secret secret-to-be-created should return a new secret created by the operator.

You can get one of its values with jsonpath (This should return Roger):

kubectl get secret secret-to-be-created   -o jsonpath='{.data.first_friend}' | base64 -d

We will add more documentation once we have the implementation for the different providers. You can find some here: https://external-secrets.io
