Connectivity Certs Controller

Overview

The Connectivity Certs Controller fetches the client certificate and the root CA from the central Connector Service and saves them to Secrets.

Fetching certificates

The Controller acts on to CertificateRequest custom resource (CR). It requires the csrInfoUrl field.

To create the CR, run:

cat <<EOF | kubectl apply -f -
apiVersion: applicationconnector.kyma-project.io/v1alpha1
kind: CertificateRequest
metadata:
  name: certificate-request
spec:
  csrInfoUrl: "{CSR_INFO_URL_WITH_TOKEN}"
EOF

After a successful exchange of certificates, the controller creates new Secrets or modifies the existing ones that correspond to the updated certificates. The CertificateRequest CR is deleted.

Troubleshooting

If there's an error in the process of fetching the certificates or saving them to Secrets, the CertificateRequest CR is not deleted. Instead, the controller adds the error section that contains a detailed error message to the CR.

To get the error message, run:

kubectl get certificaterequests.applicationconnector.kyma-project.io {CERT_REQUEST_NAME} -o jsonpath={.status.error}
