Test

Before pull request, please run test.sh script from the scripts folder for checking errors.

Code coverage

After executing test.sh file coverage.out with code coverage statistic will be generated. For view this file in HTML format use:

go tool cover -html=coverage.out

Run

For running use:

go run .

Deployment

Docker

For building docker container use:

sh scripts/build_docker.sh

For deploy app with docker run script in docker folder:

docker-compose up -d
