AWX/k8s - SSL certificate problem: unable to get local issuer certificate"

I installed awx on minikube following the official documentation :https://github.com/ansible/awx-operator

I have created the bundle certificate following the documentation, I added it to my awx.yaml (kind: awx) under “spec”.

I made sure the secret was generetaed inside the awx namespace.

kubectl create secret generic -custom-certs
–from-file=bundle-ca.crt=<PATH/TO/YOUR/CA/PEM/FILE>

*** Take note here, it says The certificate should be PEM type, ***

One thing I don’t get tho, I created the secret from the “bundle-ca.crt” located on my gitlab server, however the documentation states that the file should be .PEM
Why should I need a PEM if I already have the bundle-ca.crt available ???

Even after adding the certificate, I am still unable to synchronize my git project.

My GitLab server is on the local network, however I am not willing to disable ssl check. I would like to fix this the clean way.
