COPY after .war is deployed via docker-compose

Hey guys,

I have a docker-compose for Tomcat8 and I put my .war in there

  web:
    image: tomcat:8.5-jre8
    build:
      context: 
        ./frontenddockerfile
    ports:
      - "80:8080"
      - "443:443"
    expose:
      - '80'
      - "443"
    volumes:
      - ./logs/:/usr/local/tomcat/logs/
      - ./war/restv2.war:/usr/local/tomcat/webapps/restv2.war
      - ./oo_conf/server.xml:/usr/local/tomcat/conf/server.xml
      - ./oo_conf/context.xml:/usr/local/tomcat/conf/context.xml
      - ./oo_lib/mysql-connector-java-5.1.29-bin.jar:/usr/local/tomcat/lib/mysql-connector-java-5.1.29-bin.jar
    depends_on:
     - db

After the .war is deployed and I have the folder structure, I basically want to copy the contents of a folder into the web folder (COPY src /usr/local/tomcat/webapps/restv2). and of course, for that to work the folder structure needs to be there…

Is it also possible to have another service that I just use for copy jobs after all my real services are up and running? and if so how would that look like, what would I put in “FROM” of the dockerfile?

Any ideas?

Thank you so much!
