Secret Type - PKI

The PKI-Type is made to connect to the PKI - Secrets Engine of HashiCorp Vault. It generates certificates X.509 Certificates and refreshes them if they are near the expiration date.
How To
First generate a PKI in Vault and create a rule to issue new certificates:
This is only a test pki, for info how to generate a more secure pki please read the manual of HashiCorp Vault!
$ vault secrets enable -path=testpki -description=testpki pki
$ vault secrets tune -max-lease-ttl=8760h testpki
$ vault write testpki/root/generate/internal \
      common_name=koudingspawn.de \
      ttl=500h
$ vault write testpki/roles/testrole \
      allowed_domains=*.koudingspawn.de \
      max_ttl=8760h
After this create the following Vault-Resource and apply it to Kubernetes:
apiVersion: "koudingspawn.de/v1"
kind: Vault
metadata:
  name: test-pki
spec:
  path: "testpki/issue/testrole"
  type: "PKI"
  pkiConfiguration:
    commonName: "vault.koudingspawn.de"
    ttl: "8h"
​
This issues a new certificate that is available in your Kubernetes secret resource. It's saved in the format that Ingress can use to read them as certificates. For more details on ingress configuration please see: https://koudingspawn.de/advanced-ingress/​
