Conjur Provider

The following sections outline what is needed to get your external-secrets Conjur provider setup.

Pre-requirements

This section contains the list of the pre-requirements before installing the Conjur Provider.

Running Conjur Server
- These items will be needed in order to configure the secret-store
  - Conjur endpoint - include the scheme but no trailing '/', ex: https://myapi.example.com
  - Conjur credentials (hostid, apikey)
  - Certificate for Conjur server is OPTIONAL -- But, when using a self-signed cert when setting up your Conjur server, it is strongly recommended to populate "caBundle" with self-signed cert in the secret-store definition
Kubernetes cluster
- External Secrets Operator is installed

Create External Secret Store Definition

Recommend to save as filename: conjur-secret-store.yaml

apiVersion: external-secrets.io/v1beta1
kind: SecretStore
metadata:
  name: conjur
spec:
  provider:
    conjur:
      # Service URL
      url: https://myapi.conjur.org
      # [OPTIONAL] base64 encoded string of certificate
      caBundle: OPTIONALxFIELDxxxBase64xCertxString==  
      auth:
        apikey:
          # conjur account
          account: conjur
          userRef: # Get this from K8S secret
            name: conjur-creds
            key: hostid
          apiKeyRef: # Get this from K8S secret
            name: conjur-creds
            key: apikey

Create External Secret Definition

Important note: Creds must live in the same namespace as a SecretStore - the secret store may only reference secrets from the same namespace. When using a ClusterSecretStore this limitation is lifted and the creds can live in any namespace.

Recommend to save as filename: conjur-external-secret.yaml

apiVersion: external-secrets.io/v1beta1
kind: ExternalSecret
metadata:
  name: conjur
spec:
  refreshInterval: 10s
  secretStoreRef:
    # This name must match the metadata.name in the `SecretStore`
    name: conjur
    kind: SecretStore
  data:
  - secretKey: secret00
    remoteRef:
      key: data/app1/secret00

Create Kubernetes Secrets

In order for the ESO Conjur provider to connect to the Conjur server, the creds should be stored as k8s secrets. Please refer to https://kubernetes.io/docs/concepts/configuration/secret/#creating-a-secret for various methods to create secrets. Here is one way to do it using kubectl

NOTE: "conjur-creds" is the "name" used in "userRef" and "apikeyRef" in the conjur-secret-store definition

# This is all one line
kubectl -n external-secrets create secret generic conjur-creds --from-literal=hostid=MYCONJURHOSTID --from-literal=apikey=MYAPIKEY

# Example:
# kubectl -n external-secrets create secret generic conjur-creds --from-literal=hostid=host/data/app1/host001 --from-literal=apikey=321blahblah

Create the External Secrets Store

# WARNING: this will create the store configuration in the "external-secrets" namespace, adjust this to your own situation
#
kubectl apply -n external-secrets -f conjur-secret-store.yaml

# WARNING: running the delete command will delete the secret store configuration
#
# If there is a need to delete the external secretstore
# kubectl delete secretstore -n external-secrets conjur

Create the External Secret

# WARNING: this will create the external-secret configuration in the "external-secrets" namespace, adjust this to your own situation
#
kubectl apply -n external-secrets -f conjur-external-secret.yaml

# WARNING: running the delete command will delete the external-secrets configuration
#
# If there is a need to delete the external secret
# kubectl delete externalsecret -n external-secrets conjur

Getting the K8S Secret

Login to your Conjur server and verify that your secret exists
Review the value of your Kubernetes secret to see that it contains the same value from Conjur

# WARNING: this command will reveal the stored secret in plain text
#
# Assuming the secret name is "secret00", this will show the value
kubectl get secret -n external-secrets conjur -o jsonpath="{.data.secret00}"  | base64 --decode && echo
