A set of apps and config for me to experiment with Istio features, outside of the safety of the BookInfo sample app that ships with Istio itself.

Some inspiration for ideas from istiobyexample.dev as well as the Istio docs themselves.

Each app ships with a Makefile. For development you may also wish to go get github.com/pilu/fresh for your $GOPATH and then you can benefit from hot reloads by just running fresh.

• Basic frontend app
• Integrate the above with basic backend app
• is it worth it? CI pipeline to deploy both to separate namespaces
• Validate Envoy injection
• Istio features to explore:
  • Observability
    • Topology / service graphing
    • In/out metrics
    • Access logging
    • Distributed trace collection
  • Operability
    • Route by header
    • Canarying
    • Request timeouts
    • Circuit breaking
    • Fault injection
    • Retries
    • Traffic mirroring
  • Security
    • mTLS
    • validate JWTs
    • Auth policies
    • Third party traffic monitoring

I'm not great with Golang, so a few objectives for me while building these apps too:

• Move tests out of root - is Go too opinionated for this?
• Watch Tests equivalent
• Proper logging
• Test coverage
• Clean close of app
