Sample HTTP Application

The sample HTTP application implements the correct shutdown behavior for an HTTP application deployed to Cloud Foundry. It adheres to the following contract when shutting down:

• App receives termination signal
• App closes listener so that it stops accepting new connections
• App finishes serving in-flight requests
• App closes existing connections as their requests complete
• App shuts down (or is KILLed)

This application implements the connection management itself in main.go, but similar logic can be found in the Shutdown method of the Golang HTTP server.

Configure

The app is configurable by setting the following environment variables:

• PORT: The port on which the HTTP server will be listening. It defaults to 8080.

Response Latency

The response latency can be controlled by setting the query parameter wait to any string parseable by time.ParseDuration. The default value is 10 µs.

Deploy to Cloud Foundry

Simply run cf push from the app root directory and it should deploy successfully.

Run Locally

To run locally, follow the steps below:

et ./...
uild .
mple-http-app

To run the tests, first get the dependencies using go get -t ./... && go get github.com/onsi/ginkgo/ginkgo then run ginkgo in the app root directory.
