An example project that demonstrates a live-updating Java server in Kubernetes. Read doc.

We used Spring Initializr to bootstrap the project, then added Docker & Kubernetes configs for running it in Kubernetes.

To run these examples, you should also have:

• javac (a JDK)
• unzip
• rsync
• python3

This progression of examples shows how to start, and incrementally update your project for live updates.

• 0-base: The simplest way to start
• 1-measured: Use local_resource to measure your deployment time
• 2-optimized: Compile executable Jars and copy them into Docker
• 3-unpacked: Unpack the executable Jar into Docker layers
• 4-recommended: Live update executable Jars

• 101-jib: An example of how to integrate Tilt with the Jib Java image builder
• 102-jib-live-update: An example of how to use live_update with Jib. It requires a lot of knowledge of Jib internals, but you can make it work!
• 103-micronaut: An example of how to integrate Tilt with the Micronaut framework.
• 201-quarkus-live-update: An example of how to use live_update with Quarkus, a container-first, hot-reloading framework for writing Java applications.
• 401-spring-boot-layertools: An example of how to further optimize the Spring Boot image with the latest recommendations from the Spring Boot Docker guide.
