Check docs from http://localhost:6060/pkg/gitlab.com/mfcekirdek/in-memory-store/?m=all

Project setup

go mod download

Run lint checks

golangci-lint should be installed before running tests.

https://golangci-lint.run/usage/install/

make lint

Run tests

Mockgen framework should be installed before running tests. Follow the instructions in this link.

Generate mocks and run tests:

export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
make test

Build project

make build

Run

You can simply run the app with default configurations:

make run

Or set configs by exporting environment variables.

export IS_DEBUG=true
export APP_NAME=kv-store
export PORT=8080
export STORAGE_DIR_PATH=storage
export SAVE_TO_FILE_INTERVAL=10
make run

Built With

1. Go

   • Go standard library
   • github.com/spf13/viper --> For reading env configs at startup.
   • github.com/k0kubun/pp --> For printing app configs in a pretty format.
   • github.com/golang/mock --> For mocking components in tests.

2. Other Technologies and Components

   • Swagger for API design and documentation.
   • Postman
     • You can find exported Postman collection file here
   • godoc for code documentation.
     • pkg/gitlab.com/mfcekirdek/in-memory-store
     • Too see documentation of not exported packages, ?m=all parameter to the end of the url.
       • Example: http://localhost:6060/pkg/gitlab.com/mfcekirdek/in-memory-store/?m=all
   • Docker
     • build and push images to the private gitlab registry.
     • tag the image with branch name (main) and pipeline id
       • image:
         • registry.gitlab.com/mfcekirdek/in-memory-store/main
   • Kubernetes (Created a cluster at Digital Ocean with 2 nodes)
     • Namespace: in-memory-store-30556712-test

     • Service
       • NodePort Service for deployment (Port: 30000)
   • Sonarqube for code coverage assessment
     • Pipeline fails if the coverage decreases under 80%
     • Deployed to kubernetes cluster
   • GitLab CI/CD Pipeline for automation
