在 Jenkins 上部署 Spring 引导应用程序

Question

I am deploying Spring Boot App on Jenkins port 8081. I have tomcat running on port 5050. When I deploy the App it shows a Success message but when I navigate to localhost:5050/{given context name} it shows me a 404 Not found message. I have also tried using the embedded way it doesn't work if there is any way for deploying with embedded tomcat that will be more good

Answer 1

Jenkins is a CI/CD software to build your application (and not to deploy it on the Jenkins server). Where you run it is a different topic. Jenkins does everything right building your java executable (.war). What you should do now is to run this built executable on a server.

Consider using Docker to build your application in Jenkins and start the resulting docker container on a different server.
