Learning Go through creating simple REST API HTTP server

• Standard Go Project Layout
• Codeship Golang Best Practices
• SQL library to be used

Commands:

• Create user:

  curl --request POST --data '{"email":"[email protected]","password":"1234567"}' --verbose http://localhost:8080/users

• Log In:

  curl --request POST --data '{"email":"[email protected]","password":"1234567"}' -c cookie.txt --verbose http://localhost:8080/sessions

• Get current user name (passed by middleware through context):

  curl --request GET -b cookie.txt --verbose http://localhost:8080/private/whoami

• Headers:

  curl --request GET -b cookie.txt -H "Origin: blinnikov.com" --verbose http://localhost:8080/private/whoami

Migrations

• create

  migrate create -ext sql -dir migrations migration_name  

• run migration

   migrate -path migrations -database "postgresql://postgres:changeme@localhost/restapi_test?sslmode=disable" up

Serving through TLS

• install openssl

  brew update
  brew install openssl

• genereate Self-Signed Certificate

  openssl req -newkey rsa:4096 \
           -x509 \
           -sha256 \
           -days 3650 \
           -nodes \
           -out go-rest-api.crt \
           -keyout go-rest-api.key

• use http.ListenAndServeTLS

  return http.ListenAndServe(config.BindAddr, srv)

  ->

  return http.ListenAndServeTLS(config.BindAddr, "go-rest-api.crt", "go-rest-api.key", srv)

Deploy to local k8s

• Give create-configmap.sh script execution permissions

  chmod +x ./k8s/create-configmap.sh 

• Run this script to create config maps for certificate files

  ./k8s/create-configmap.sh

• Install all kubernetes objects

  kubectl apply -f ./k8s --recursive
