How to find java app hosting(ISP) or How to deploy Spring Boot website to Koyeb

Spring boot is the most famous java framework, and I have been looking for a simple way to serve a java app on a hosting service(not dedicated which is very expensive not AWS/Azure which are too complicated), Most shared hosting does not support java apps, they support php or asp or perl here is the table for godaddy webhosting supported tech.

I will explain how to deploy from dockerhub to Koyeb, or we can deploy from github repository too.

1. Develop a SB app make sure everything works in the local.
2. Run mvn spring-boot:build-image -Dspring-boot.build-image.imageName=target-docker-namespace/app-name this will generate the image of the app in the local docker.
3. Push the image to docker hub, docker push /getting-started-todo-app or use docker desktop

1. Go to koyeb dashboard and click Create webservice then choose docker and configure accordingly, system will generate us a subdomain where we can test, then do the dns connection and our site is online.

I spend around 2 hours until make the app work in docker image, needed to update pom xml versions and plugins, better to follow the https://start.spring.io/ which has the best pom.

At Koyeb side, while configuring the instance I changed the port to 8080, if we do not choose the port used by SB it may not work.

For now this looks like will take 5.36$ monthly. I use 1 eSmall instance I took a screen shot just for future reference, and see how inflation affect them
