Get ca.crt files for TLS

General
1

I am currently trying to setup the communication between two Kubernetes clusters and they should reach each other via a subdomain hosted at Cloudflare.

I have generated an Origin Certificate for it and it yields tls.crt and tls.key. However, the config I have to set looks as follows:

existingSecret:
  name: thanos-client-cert
  keyMapping:
    ca-cert: ca.crt
    tls-cert: tls.crt
    tls-key: tls.key

Hence, I am ca.crt here. Do you know how I can get it?

Is is possible you need to specify the CA certificate so that it can be sent to the client during the handshake. The Cloudflare Origin CA certificate can be downloaded here: Origin CA certificates ยท Cloudflare SSL/TLS docs.
