Cloud Run project template

This repo contains a GCP Run project template. It comes with the following design decisions:

• It uses Spring Boot as the web framework.
• It uses Gradle to manage the build.
• It's 100% Kotlin (with Java 8 compatibility).

Features

Besides the basic functionality provided by Spring Boot, the following features are included:

• A Makefile to automate deploying and running locally using Docker (see below for details).
• A Dockerfile suited for Gradle-based projects.
• A sample RootController that will print out values for key environment variables.
• Configured to use GCP Spring extensions (spring-cloud-gcp-starter).

Running it locally

During development, you probably want to use IntelliJ IDEA. Simply open the project, the IDE will recognize it's a Spring project and will add the right run configuration.

Docker

The Makefile automates the basic tasks you need from this project:

• make build-image: Builds the Docker image using GCP Cloud Build.
• make run-image: Runs the Docker image locally (for testing purposes).
• make deploy-image: Deploys the image. We're setting the memor to 512M instead of the default 256M (otherwise, the container will fail to deploy despite using -XX:+UseCGroupMemoryLimitForHeap).

Endpoints

• /: Should respond OK. with a 200.
• /info: It'll print a JSON object with a number of environment variables. A sample output would look like:

{
  "now": 1555286644082,
  "port": "8080",
  "javaVersion": "jdk8u202-b08",
  "krevision": "template-00003",
  "kservice": "template",
  "kconfiguration": "template"
}
