Circle CI Multi-Cloud Kubernetes Demo
Build, Test and Deploy a simple webapp using CircleCI, Docker, Kubernetes and CloudFlare DNS.
This project repo is the source code companion a series of CircleCI Blog posts. [ADDRESS]
To test simple UI functionality we're using Spring Boot's test starter and Selenium's
WebDriver interface. If you'd like an isolated example building Docker containers from Java, checkout CircleCI Jib demo project
To turn our executable jar into a Docker image we're using Jib, a project from Google.
Locking into a single cloud provider can reduce initial investment, but may limit future portability. This demo targets k8s on a few major providers
GCP (Google Cloud)
We'll install gcloud cli and kubectl to manage our interations with Google's cluster orschestration.
AWS ECS (Amazon Container Service)
It's easy to use static IPs with a single cloud provider, but when you want your application across many providers or regions, you might want a global DNS solution. THis demo uses CloudFlare which has a rich API for enabling and re-routing traffic through our deployment lifecycle.

Cloud Specific URLS
Yeah, that'd be cool, TBD.
This project uses spring boot, so run as you would any other like project to start on port :8080 locally.
