     image: 2021.jar
     image: tomcat:9.0-jdk8
     volumes:
      - ./ROOT:/usr/local/tomcat/webapps/ROOT
      - ./repository:/usr/local/tomcat/webapps/ROOT/repository
     ports:
      - '8089:8080'
     environment:
      - JAVA_OPTS= -Ddb.host=localhost -Ddb.catalog=gohybridit_dev -Ddb.port=5432 -Ddb.username=postgres -Ddb.password=123

and this my Dockerfile

FROM openjdk:8-jdk-alpine
ARG JAR_FILE=target/*.jar
COPY ${JAR_FILE} 2021.jar
ENTRYPOINT ["java","-jar","2021.jar"]

    I come with this command and solved my problem

    docker run -d -p portNum:portNum --restart always XXXXX.jar

    I am guessing you are setting port 8089 in your application properties. If you are, either:

    a) update the docker-compose to say '8089:8089' instead.

    b) update application properties to set the port to 8080 (or remove it altogether as this is the default)

    Basically, those ports are <outside container>:<inside container>. I personally would match all the ports to 8089 per the first option to reduce confusion.
