Create a Certificate and CA Certificate
Use KongCertificate and KongCACertificate to manage TLS credentials and CA Certificates
Prerequisites
Kong Konnect
If you don’t have a Konnect account, you can get started quickly with our onboarding wizard.
- The following Konnect items are required to complete this tutorial:
- Personal access token (PAT): Create a new personal access token by opening the Konnect PAT page and selecting Generate Token.
-
Set the personal access token as an environment variable:
export KONNECT_TOKEN='YOUR KONNECT TOKEN'Copied to clipboard!
Create a KongCertificate
Use the KongCertificate resource to provision a TLS certificate in Konnect. The certificate must be associated with a KonnectGatewayControlPlane.

Create a KongCACertificate
Use the KongCACertificate resource to provision a CA certificate in Konnect. This certificate can be used for client authentication or mutual TLS setups.

Validation
Check that Programmed is True on the cert resource:
You can verify the KongCertificate was reconciled successfully by checking its Programmed condition.
kubectl get -n kong kongcertificate cert \
-o=jsonpath='{.status.conditions[?(@.type=="Programmed")]}' | jq
The output should look similar to this:
{
"observedGeneration": 1,
"reason": "Programmed",
"status": "True",
"type": "Programmed"
}
Check that Programmed is True on the ca-cert resource:
You can verify the KongCACertificate was reconciled successfully by checking its Programmed condition.
kubectl get -n kong kongcacertificate ca-cert \
-o=jsonpath='{.status.conditions[?(@.type=="Programmed")]}' | jq
The output should look similar to this:
{
"observedGeneration": 1,
"reason": "Programmed",
"status": "True",
"type": "Programmed"
}
