Not able to run my Spring Boot WAR file in docker container

Question

Here is my Dockerfile:

FROM tomcat:8.0-alpine

RUN rm -rf /Users/firstname.lastname/Desktop/Backup/apache-tomcat-9.0.30/webapps/*

ADD./target/restfullapi-0.0.1-SNAPSHOT.war /Users/firstname.lastname/Desktop/Backup/apache-tomcat-9.0.30/webapps/restfullapi.war

EXPOSE 8089

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

---

Once I build the.war file I do the following steps:

docker build -t restfullapi.war. docker run -d -p 8085:8089 restfullapi.war Now when I open localhost:8085 I am able to see only tomcat home page which is correct, but the problem is If I try to access -->> localhost:8085/restfullapi/movies I get 404 error.

and here is my pom.xml

You can run a SpringBoot application in Docker using the default embedded Tomcat. This avoids the need to create a WAR file and provide Tomcat yourself.

FROM adoptopenjdk/openjdk11:latest

RUN mkdir -p /software/app

ADD target/restfullapi.jar /software/app/restfullapi.jar

ENV port=8888

CMD java -jar /software/app/restfullapi.jar -Dspring.profiles.active=${SPRING_ACTIVE_PROFILE}
