Sidecar proxy using jaeger

Jaeger Proxy

It creates a sidecar proxy to be used with distributed applications in a microservices/kubernetes setup. Proxy2 has a simple python proxy which inserts a jaeger tracing header into incoming HTTP requests.

This helps minimal changes to existing applications and create a tracing infrastructure for looking at data-flow paths in large scale apps.

Pod contains IP Tables rule to forward any incoming application request to the proxy's port.

Usage

proxy_bookinfo.yaml is sample istio application which has the necessary proxy and jaeger agent inserted.

Build proxy:

cd proxy2

Flask: docker build -f Dockerfile -t <org-name>/flask_proxy

Socket: docker build -f Dockerfile_socket -t <org-name>/socket_proxy

Build init pod:

cd pod

docker build -f Dockerfile -t <org-name>/init-container

Make sure that the bookinfo yaml file proxy/init-container image names are properly set.

Push both these images to your org dockerhub:

docker push <org-name>/<proxy/init-container>

Setup kubernetes cluster by running install_tools.sh

Setup jaeger by running deploy_operator.sh

Deploy bookinfo: kubectl apply -f proxy_bookinfo.yaml
