Dependencies and vgo

The dependencies are handled with vgo. You need to install vgo first:

go get -u golang.org/x/vgo

Then you can use vgo run main.go to start the application.

Environment

You need to set some environment variables before running this application:

• SERVER_PORT: the port for the rest api (eg: 8080)
• MONGO_URL: the mongodb address (eg: 127.0.0.1:27017)

To use the default values you can use the default_env.sh script:

source default_env.sh
vgo run main.go

Run with docker

It is also possible to run this application with docker compose:

docker-compose -f docker/compose.yml up --build

Or if you only want to run mongo in docker and not the rest api:

docker-compose -f docker/mongo.yml up
