my docker-compose.yml:

  helpers:
  ssh-config:
services:
  mail:
    image: djfarrelly/maildev
    ports:
      - "127.0.0.1:1080:80"
  redis:
    image: redis
  db:
    image: postgres
    command: -c fsync=off
    volumes:
      - db:/var/lib/postgresql/data
  db_templates:
    image: postgres
    command: -c fsync=off
    volumes:
      - db_templates:/var/lib/postgresql/data
  web:
    build: .
    volumes:
      - ./:/home/user/${COMPOSE_PROJECT_NAME}/
      - files:/home/user/files/
      - db:/db
      - helpers:/home/user/.pycharm_helpers/
      - ssh-config:/etc/ssh/
    ports:
      - "127.0.0.1:8000:8000"
      - "127.0.0.1:8022:22"
    depends_on:
      - db
      - db_templates
      - redis
    command: bash -c "/home/user/${COMPOSE_PROJECT_NAME}/bin/helpers/run && sleep infinity"

and my dockerfile for the webcontainer:

FROM ubuntu:trusty
# install system packages
RUN apt-get update -qq -y && export DEBIAN_FRONTEND=noninteractive && apt-get install -qq -y \
    gettext git libffi-dev libpq-dev ntp openssh-server python python-pip python-dev sloccount vim\
    && pip install virtualenv virtualenvwrapper
......

if i now run docker-compose pull all images will updated if a new version is there.
But my Ubuntu from the Dockerfile is not updated. then i have to run by hand "docker pull ubuntu:trusty"

Is it possible on a "Docker-compose pull" to check also the dockerfiles with their images automatically?

docker-compose build --pull is what you're looking for, I believe.

Hey @shin- thanks, but than i have to run "docker-compose pull", "docker-compose build --pull" and "docker-compose up -d --build" for my app env. the seccond --build is redundant i know.

I think maybe it could a good practices to learn the up command --pull ?
