developer-experience-java-kubernetes's Introduction

Developer Experience with Java on Kubernetes

In the cloud-native world, being a developer might be challenging. The number of technologies and patterns to know can be overwhelming. This repository presents an approach based on open-source technologies and focused on improving the inner development loop and continuous delivery on Kubernetes. The end goal is delivering value continuously, quickly, and reliably.

The approach works with any Java application, but we'll use Spring Boot for our examples. Some of the open-source technologies covered are:

Cloud Native Buildpacks
Knative
Tilt
Skaffold
Telepresence
Argo CD.

For each tool/strategy there is a dedicated folder within which you'll find instructions on how to setup your environment.

Pre-requisites

Running through the examples will require you to have the following installed on your machine:

To manage different versions and distributions of Java, I recommend using SDKMAN!.

Finally, to interact with HTTP services, I recommend using httpie.

How Tilt livereload works?

Can you explain a bit on how live-reload works in case of tilt?

# Build
custom_build(
    # Name of the container image
    ref = 'book-service',
    # Command to build the container image
    command = './gradlew bootBuildImage --imageName $EXPECTED_REF',
    # Files to watch that trigger a new build
    deps = ['build.gradle', './bin/main'],
    # Enables live reload
    live_update = [
        sync('./bin/main', '/workspace/BOOT-INF/classes')
    ]
)

# Deploy
k8s_yaml(['config/deployment.yml', 'config/service.yml'])

# Manage
k8s_resource('book-service', port_forwards=['8080:8080', '9090:9090'])

In particular, what exactly is './bin/main'? I'm asking this question because I can't get this work and official examples are completely different.
