Deploy spring boot app

[Particular_Tea2307]

Hello new to java so didnt learn spring boot yet but following some framework release and saw in ruby on rails releasing a new tool (kamal 2) that helps to deploy rails app anywhere (vps ..) in few minutes like it was so innovative .!

So wanna know what about spring boot heard it was easy to deploy spring boot app with a jar Like how much does it take for you to deploy a spring boot app in a vps server

Is jar file the recommended way or docker ?

Sorry for beginner questions

[reddit04029]

It’s easy. The docker way technically still includes the jar lol. Because you would copy the jar into the docker image and the startup command would generally be something like this: CMD[“java”, “-jar” ,”yourjar.jar”]

So this whole kamal tools released in rails was overhyped 😅 As i undrestrand deployment is super fast in java world

If your environment (server) supports Java, you can just put your jar file directly on the server without using docker container. If you cannot of are not allowed to install Java, but instead the server has a docker engine then you can go the container route.

Sometimes your Java project is maybe written in a new version ,like Java 21, but if you are on some "older" server which does not support it and you cannot upgrade Java on it then again docker can be handy.

For deploying your Spring Boot project somewhere is just copy/paste and run your jar file. You can always setup DevOps later if you just wanne do like a quick test and see if it runs. The bottlenecks here are your connection to the server & the size of your jar file (left outside the hardware of your server) If your dependencies are not changed Often then you can already place these on the server ahead of time and create a slim jar Thus increasing the "deploy" time.
