Tips for generating gRPC protocol buffers

You can use the flag -I or -proto_path to specify the path to your protobuffer. The next flag specifies the language to compile to. The Go command is fairly well documented but the Node.js documents seem to only show how to dynamically load a proto file. This is how you generate a compiled file for use in your Node.js project.

GO

protoc --proto_path=$SRC_PATH --go_out=plugins=grpc:$DEST_PATH $SRC_PATH/service.proto

Node.js

protoc --proto_path=$SRC_PATH --js_out=import_style=commonjs,binary:$DEST_PATH --grpc_out=./ --plugin=protoc-gen-grpc=node_modules/grpc-tools/bin/grpc_node_plugin $SRC_PATH/service.proto

Istio Auth Policy and Mesh Policy Results

Test the behavior of various implementations of mTLS for Auth Policies AND Mesh Policies so that we have the right logic implemented when we determine the config mTLS state for the Details API

Set Up

For testing these scenarios, I installed AspenMesh in a bare cluster without enabling mTls by default (use install/kubernetes/aspenmesh.yaml) but otherwise set it up normally according to the Aspen Mesh and Istio Docs.

I used the Istio setup described here

Follow the setup steps in this doc

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}
