3 Develop

Getting Started:

1. Clone repository.
2. From project root run make dev.
3. Send test request to krakend curl -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c" http://localhost:8080 -v.

3.1 Makefile

make build

Builds confluent-rest-proxy.go for production and outputs in to the ./build directory.

make dev does the following:

1. Start docker containers specified in docker-compose.yml.
2. Builds confluent-rest-proxy.go and outputs binary to ./krakend/plugins so it can be injected by the krakend container.
3. Restarts krakend container.
4. Tails krakend log.

make dev-build does the following:

1. Builds confluent-rest-proxy.go and outputs binary to ./krakend/plugins so it can be injected by the krakend container.
2. Restarts krakend container.
3. Tails krakend log.

make dev-stop

Stops all containers, same as docker-compose down

curl -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c" http://localhost:8080 -v
