httpbin_client_mtls_using_secret.yaml

# Here we are creating an API definition with MTLS Auth for httpbin 
#
# We assume that TLS secret `my-test-tls` which stores client certificate already exists in the namespace
# you are creating this API
#
# You can generate self signed key pair using below command
# openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes
#
# Create secret for above certificate
# kubectl create secret tls my-test-tls --cert cert.pem --key key.pem
