Be sure to change the username in the command below to your Docker username: If you want to push the container to the public Docker Hub you will need to login via the terminal (вЂњdocker loginвЂќ) and then push the image. This is a screenshot of me running the app via Docker: If you are using something other than Docker for Mac you may have to figure out the default IP address that Docker is exposing apps on, rather than using localhost. Once everything has initialized you can visit localhost:8080 in your browser (being sure to have terminated the app that was running via your IDE first). $ docker run -p 8080:8080 -t docker.io/danielbryantuk/springsample:latest You can now test that the app runs successfully via Docker by using the following command: Job done! You just built your app into a container and there wasnвЂ™t a Dockerfile in sight! You can see the result of me running this command with my username вЂњdanielbryantukвЂќ, below: You can change the token вЂњ**YOUR DOCKER HUB USERNAME**вЂќ to your Docker account username if you want to follow along and upload this image to your account. If you bring up a (Linux style) terminal and navigate to the root of your application project, you can simply type the following command to build a Docker image with your app included.

On my local machines I typically run Docker for Mac / Windows, but other solutions do exist. As of Spring Boot 2.3.X this is no longer the case, as you can now take advantage of inbuilt container buildpacks.ДЇirst, you will need to ensure Docker is running on your local machine. In the past, this used to be the point where I would have to discuss creating a Dockerfile and explain how important it is to make good choices about all of the config included in this. Next, you can set about containerizing your application. The above screenshot shows my run of the application via IDEA, with the web browser output below. You should be able to visit localhost:8080 and see the вЂњHello, World!вЂќ message. If you run the application in your IDE the Spring skeleton provided by the Initializr should spin up an embedded Tomcat server and expose your application via port 8080 on localhost.

Obviously this isnвЂ™t a demonstration of proper REST style, as you should be returning entities or aggregates, but hopefully you get the idea and can build on this. You can see that this is super simple: any request to the root path (вЂњ/вЂќ) will return вЂњHello, World!вЂќ. Next, you can add a simple REST(ish) Spring Boot Controller that you will use as an example user-facing endpoint for your application.Д¬reate a package named and create a Class here named HelloWorld.ДЄdd the following contents to the new HelloWorld Class.

IвЂ™m going to use JetBrainsвЂ™ IntelliJ IDEA in this tutorial, as not only is this my favourite IDE, but they also very kindly provide free licenses to Java Champions (thanks JetBrains!) REST, You Say? Not Yet, YouвЂ™re Just Getting Started! I know, I know, Gradle is where all the cool kids hang out, but IвЂ™m still a big Maven fan. As youвЂ™ve gone with the default config, the project structure will be familiar to anyone who has used Maven (thatвЂ™s hopefully most of you!).

Go ahead and extract the files and open the project in your IDE of choice.

This will generate, build, and download a ZIP file with your project skeleton. Now click вЂњGENERATEвЂќ (via the button at the bottom of the page). I remember first seeing Josh Long demo the Spring Initializr live at a Devoxx event many years ago, and now I regularly see StГ©phane Nicoll and the team discussing the evolution of the Initalizr functionality and UX.ДЇor todayвЂ™s tutorial you can head over to, have a quick look around, and then add the вЂњSpring WebвЂќ dependency (by clicking on the вЂњADD DEPENDENCIESвЂќ button on the right). If you are getting started with Spring or looking to bootstrap a skeleton of a Spring app this is my go-to recommendation. The Spring team has done fantastic work on the Spring Initializr.

In this tutorial, IвЂ™m going to show you how to bootstrap a Spring Boot web application, containerize this using the latest Spring buildpacks, and deploy this onto an application-ready Kubernetes cluster with the app exposed to users via the Ambassador API gateway.ДЄnd youвЂ™ll be able to complete this in ~30 minutes without writing a single line of YAML, thanks to the power of the Spring Initializr and the K8s Initializer websites, which create all of the boilerplate code and config for you! While thereвЂ™s no substitute for doing the research and reading the books/articles etc, IвЂ™m a big fan of learning by doing. I chat to a lot to Java and Spring developers looking to get started quickly with deploying applications on Kubernetes.
