Unable to connect application on localhost after docker deploymnet is successful

I am trying to deploy a spring boot war file on docker container

This is my docker file:

FROM tomcat:alpine

RUN wget -O /usr/local/tomcat/webapps/ROOT.war -U admin:Learning http://localhost:8082/artifactory/demoArtifactory/com/demo/0.0.1-SNAPSHOT/demo-0.0.1-SNAPSHOT.war

EXPOSE 8080

CMD ["catalina.sh", "run"]

enter image description here

I am unable to connect to localhost:7000

UPDATE: This is the docker run command:

docker run -it --name demo-application -d -p 8080:8080 hmt/demo-application:49

"PortBindings": {
                "8080/tcp": [
                    {
                        "HostIp": "",
                        "HostPort": "8080"
                    }
                ]
            }

Now my tomcat is up on localhost:8080 but I am unable to access my application

UPDATE:

@SpringBootApplication
public class DemoApplication{

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}
Solution

  • 1.You need to extend SpringBootServletInitializer.Spring Boot Servlet Initializer class file allows you to configure the application when it is launched by using Servlet Container Reference: https://www.tutorialspoint.com/spring_boot/spring_boot_tomcat_deployment.htm

    2.Rename your war file from ROOT.war to something like sample.war .ROOT default app is usually Tomcat Manager
