This demo shows how to connect example Golang application in Kubernetes Engine to
a Cloud SQL instance using the Cloud SQL Proxy library.
First we will deploy a Kubernetes Engine
cluster and a Cloud SQL Postgres instance
and the Golang test app container.

This tutorial assumes you have access to the Google Cloud Platform and you already have initialized gcloud with default project, region and zone set. Otherwise, do the following steps:
gcloud init- Enter your email address,
- Choose your project or create a new one,
gcloud config set compute/zone ZONEgcloud config set compute/region REGION
ZONE and REGION list could be found here:
gcloud compute zones list
If you don't have a Google Cloud account you can sign up for a free account.
It's better to install a fresh version of kubectl with gcloud:
gcloud components install kubectl
All deployment processes are fully automated. The main entry point here is make.sh bash-script (in case if someone doesn't have make installed). There are some options:
Usage: ./make.sh option"
Options: docker-build, -- run docker-compose up -d --build
docker-cleanup -- run docker-compose down & system prune"
gcp-build (optional flag: -t v0.x.x), -- build Docker image and push to gcr.io"
gcp-create, -- run GCP provisioning and deployment"
gcp-destroy, -- destroy GCP resorces"
Run docker-compose deployment and tests locally:
./make.sh docker-build
Run GCP full infrastructure deployment:
./make.sh gcp-create
Build docker image with new tag and push to gcr.io:
./make.sh -t 0.1.11 gcp-build
Run deployment with new tag and scaled with 3 replicas:
./make.sh -t 0.1.11 -c 3 gcp-deploy
./make.sh docker-cleanup
./make.sh gcp-destroy
