go-mux

Golang Mux Demo

Run locally

• Start postgres
• Prepare environment, fill DB parameters:

$ cp env-sample .env
$ $EDITOR .env
$ source .env

• Create the public IPs, one for loadbalancer and another for ingress

gcloud compute addresses create go-mux-api-ip-ing --global
gcloud compute addresses create go-mux-api-ip-lb --region us-west1

• Run PostgreSQL container and create the databases or use docker-compose

• Docker

$ docker run --name postgres-db -p 5432:5432 -e POSTGRES_PASSWORD=${APP_DB_PASSWORD} -d postgres
$ echo "SELECT 'CREATE DATABASE ${APP_DB_NAME}' WHERE NOT EXISTS (SELECT FROM pg_database WHERE datname = '${APP_DB_NAME}')\gexec" | \
psql "user=${APP_DB_USERNAME} password=${APP_DB_PASSWORD} host=127.0.0.1 port=5432"
$ echo "SELECT 'CREATE DATABASE ${TEST_DB_NAME}' WHERE NOT EXISTS (SELECT FROM pg_database WHERE datname = '${TEST_DB_NAME}')\gexec" | \
psql "user=${TEST_DB_USERNAME} password=${TEST_DB_PASSWORD} host=127.0.0.1 port=5432"

• Docker-compose

$ docker-compose build
$ docker-compose up -d

• Build and run:

$ go get -u github.com/gorilla/mux github.com/go-sql-driver/mysql
$ go build -o go-mux-api.bin
$ ./go-mux-api.bin

Server is listening on localhost:8010

• GKE Setup

Create the regional IP for the LoadBalancer

$ gcloud compute addresses create go-mux-api-ip --region us-west1
