grpc

The ultimate glue for microservices

I am playing with grpc on kubernetes in these days. My starting point is
nginx-kubernets-lb. I wanted to start from small and light solution. But heroku was not an option to play with this. So I had to setup kubernetes on aws. I deployed Deis too. It took some time to be able to reproduce the production env. This blog is also running on kubernetes. Now, I am ready to play!

caution

• ruby gem - download ruby gem instead of installing grpc
• heroku - not suitable for grace. heroku does not support http2. grpc needs that.(https://devcenter.heroku.com/articles/http-routing)

polyglot

https://github.com/grpc-ecosystem/polyglot

Polyglot is a grpc client which can talk to any grpc server. In order to make a call, the following are required:

• A compiled Polyglot binary,
• the .proto files for the service,
• and a request proto instance in text format.

In particular, it is not necessary to generate grpc classes for the service or to compile the protos into the Polyglot binary.

• Supports unary, client streaming, server streaming, and bidi streaming rpcs.
• Runs on Windows, Mac and Linux.
• Parses proto files at runtime to discover services. Supports pretty-printing discovered services.
• Supports authentication via oauth.
• Accepts request protos through stdin and can output responses to stdout to allow chaining.
