ingresse-backend

ingresse-backend is a simple application developed as part of the selection process for Ingresse. The application was built using Go, and the Macaron framework.

ingresse-backend is a REST API with only one endpoint: /users. It implements the http verbs POST, GET, PUT and DELETE.

ingresse-backend uses MongoDB for data persistence.

Setting up

Since Go is not a major programming language yet, not everyone has a set up environment for it, so two options are available:

• Run natively (requires Go environment installed)
• Run under Docker (visual representation of code coverage not available)

Running natively

Assuming a working Go environment (it's critical that the GOPATH environment variable is set according to the guidelines), run:

go get -v github.com/PhillBeck/ingresse-backend/...
cd $GOPATH/src/github/PhillBeck/ingresse-backend

Then you have to set up the infrastructure. As mentioned above, ingresse-backend requires a MongoDB instance running on port 27017. For ease of use, a docker-compose file is provided to set up Mongo:

cd docker/infrastructure
docker-compose up

after that, just navigate to the directory and execute the program:

cd $GOPATH/src/github/PhillBeck/ingresse-backend
go run main.go

Running under Docker

This assumes you have both docker AND docker-compose installed.

To run under Docker, simply clone the repository:

git clone https://github.com/PhillBeck/ingresse-backend.git

then run:

cd ingresse-backend/docker/application
docker-compose up

Using this method, the infrastructure is set up automatically.

Documentation

The repository contains the swagger file in both json and yaml formats. To access the documentation in a more friendly way, a html version is also available on the docs folder.

If you are running the application under Docker, just navigate to localhost:8000 to view the docs.

If you are running natively, you can run:

cd $GOPATH/src/github/PhillBeck/ingresse-backend/docker/docs
docker-compose up

and then access localhost:8000.

Testing

Natively

Assuming a working Go environment, just run:

cd $GOPATH/src/github/PhillBeck/ingresse-backend
go test -coverprofile=cover.prof ./...

go test will output the summary of the tests to stdout. This includes code coverage for each package. For a visual representation of the code coverage, run:

go tool cover -html=cover.prof

Under Docker

After the container is running, run:

docker exec -it ingresse-backend /bin/sh
go test -coverprofile=cover.prof ./...

Unfortunately, the visual representation of the code coverage is not available when running under Docker.
