Preparing

Clone docker-envs repo:

git clone https://github.com/stn1slv/docker-envs.git

Go to root directory of the repo:

cd docker-envs

All the following docker-compose commands should be run from this directory.

Running

You may want to remove any old containers to start clean:

docker rm -f kafka zookeeper prometheus grafana kibana elasticsearch jaeger otel-collector filebeat tripbooking carbooking flightbooking hotelbooking

We suggest using two terminal windows to start the following components:

• infrastructure components
• demo apps

Startup infrastructure components

docker-compose -f compose.yml -f kafka/compose.yml -f jaeger/compose.yml -f otel-collector/compose.yml -f prometheus/compose.yml -f grafana/compose.yml -f filebeat/compose.yml -f elasticsearch/compose.yml -f kibana/compose.yml up

Startup demo apps

docker-compose -f compose.yml -f demo-apps/compose-otel.yml up

Testing

Testing tools are following:

• Any HTTP client (web browser, curl, httpie, postman etc.)
• Apache JMeter for generation load

cURL

Sync communication (over HTTP):

curl http://127.0.0.1:8080/camel/bookTrip

Async communication (over Kafka):
