Workshop: Java on Google Cloud: The Enterprise, The Serverless, and The Native

This workshop will guide you through deploying a sample Java application, randomstrings, to Google Cloud Platform (GCP) using Cloud Build.

Target Audience: Developers familiar with Java and basic cloud concepts.

Workshop Outline:

  1. Intro - theory (30 min)

  2. Setting Up The Local Environment (15 mins)

a. Clone the Repository: Start by cloning the randomstrings repository from Github. b. Code Review: Briefly walk through the Java code.

  1. Building and Running Locally (15 mins)

a. Local Build: Build the application locally using Maven.

b. Running the Application: Run the application locally to verify its functionality.

c. Building with Containers (Optional): (For those who prefer containers) We'll show you how to build and run the application within a Docker container.

  1. Deployment to GCP with Cloud Build (10 mins)

a. Cloud Build Configuration: We'll walk you through the Cloud Build configuration file (cloudbuild.yaml) and explain its components. This includes environment variables and build steps.

b. Deploying to GCP: We'll guide you through deploying the application to GCP using Cloud Build. This will involve triggering a build and monitoring the logs.

c. Example Substitutions: We'll showcase examples of using substitutions for variables like environment (dev, test, prod) or specific configurations.

  1. Deploying Multiple Versions and Testing (50 mins)

a. Versioning Your Application: Strategies for versioning your application code.

b. Deploying Different Versions: Demonstrate how to deploy different versions of the application using Cloud Build triggers and substitutions.

c. Measuring response time, setting up the liveness probes, etc.
