gRPC requires HTTP2 support, and we need to enable HTTP2 support in the cluster partition.
For the HTTPS port, you can also enable HTTP2 separately in the application settings. See this document for details.
Create gRPC Proxy Page Rule
We need to create an upstream before creating a new page rule. The gRPC upstream is configured in the same way as normal upstreams, we create an upstream called gRPC first.
Next, we create a page rule and select the upstream we just created in the proxy options.
Then turn on the
Enable gRPC Proxy option.
Save this page rule.
Now, a simple gRPC proxy rule is successfully set.
