Java Microservices Workshop

Requirements:

• JDK 17

• Docker

• Vault CLI

• KIND - Kubernetes in Docker

How to prepare

Ensure that you have JDK 17 installed. If you don’t you can check SDKMAN https://sdkman.io/install/ as a tool to manage your JDK installations (and not only those). Then you’ll be able to run this command and it should point out to JDK 17.

$ java -version

You can call the script that fetches docker images and downloads all application JARs.

$ ./scripts/download_everything.sh

Go to https://developer.hashicorp.com/vault/tutorials/getting-started/getting-started-install to learn how to install Vault CLI. Then you can make this call

$ vault --version

You need Docker and Docker Compose. If the following commands don’t return results go to this link https://docs.docker.com/desktop/ and install Docker and Docker Compose.

$ docker --version
$ docker compose version

Go to https://kind.sigs.k8s.io/docs/user/quick-start to learn how to install KIND. If you install it then you can run this command to create a cluster

$ kind create cluster

If you’re using Windows and / or can’t run the automation script (./scripts/download_everything.sh) then ensure that you pull the Docker images for these docker compose files ($ docker compose pull)

• docker-compose.yml

• week3/part1/docker-compose.yml

Run the maven command to fetch all dependencies

$ ./mvnw dependency:go-offline
