Docker Compose - Run java web application (war file) on tomcat using volumes
you can use volumes directly in YAML files
volumes: - Path_on_local_pc:Path_on_containerthis block will be under tomcat and parallel to build and ports
tomcat: container_name: tomcat-container build: context: . dockerfile: Dockerfile_tc ports: - "8080:8080" volumes: - Path_on_local_pc:Path_on_containerYou can add likewise.

I know this answer could be late but it might help others.If it it contains a pom.xml file. Then you can create a single docker file to build the image. Without having to execute other commands
FROM maven:3.5-jdk-8 AS buildserver
WORKDIR /usr/mygitproject
git clone into container path
RUN git clone mygitproject /usr/mygitproject
WORKDIR /usr/mygitproject /src
build the project
RUN mvn -f /usr/mygitproject /pom.xml clean package -DskipTests
FROM tomcat:latest
Copy the built war file into webapps folder of tomcat container
COPY --from=buildserver /usr/mygitproject /target/*.war/usr/local/tomcat/webapps
