ssl on gke gcp

Google Cloud Serverless Applications

Hi,

i have deployed monolithic application in gcp through gitlab ci/cd. Under the cluster i am running two applications as workload, both accessible with http. Now i want to change it https, so i tried by creating the ingress.

My wildcard ssl certificate is with godaddy, i use that certificate in onprem also. When i downloaded certificate file from godaddy it has got 3 files 1 certificate, 1 bundle , 1 pem and pvt key was in cpanel(it has many pvt keys i dont know which one since it is managed my different person). So when upload .pem and one of the pvt key in gcp certificate manager it got stored without error. But when i try to use the same in ingress setup ,ingress got created but it showed error as “Error 400: The SSL certificate and key do not match., sslCertificateKeyAndCertMismatch” . And if i try upload as secret through cloud sdk i got “error: tls: private key does not match public key”.

How to resolve this ,online i dont find any end to end procedure from godaddy to gke. If anyone has any document or procedure pls share.

“Pls respond as soon as possible, my deadline is nearing”.

Thanks in advance,

Hi @vijay-33567 ,

Based on the information that you provided, you can try combining the certificate and bundle using this command below. You can do this using a text editor.

cat certificate.crt bundle.crt > combined.crt

Regarding this part that you have mentioned,

Try uploading it directly using this command :

kubectl create secret tls my-tls-secret --cert=certificate.pem --key=privatekey.pem

In addition, you can try debugging and check the secrets and certificates using the command below:

kubectl get secrets
kubectl describe secret my-tls-secret
