限制 docker-compose 的日志量

Question

我有一个 rails 项目，我从

开始

docker-compose up

但是每次我启动它时，docker-compose 输出所有以前容器的日志，并且越来越多...

如何限制启动时登录的输出？

这是我的 docker-compose.yml，它有帮助...

web:
  build: .
  command: bundle exec rails s -p 3000 -b '0.0.0.0'
  environment:
    RAILS_ENV: development
  volumes:
    - .:/rcd
  ports:
    - "3000:3000"
  external_links:
    - postgres:db
  volumes_from:
    - bundle
bundle:
  image: rcd_web
  command: echo "hi"
  volumes:
    - /bundle

这是 Dockerfile：

FROM ruby:2.1
RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs
ENV APP_HOME /rcd
RUN mkdir $APP_HOME
WORKDIR $APP_HOME
ADD Gemfile* $APP_HOME/
ENV BUNDLE_GEMFILE=$APP_HOME/Gemfile \
BUNDLE_JOBS=2 \
BUNDLE_PATH=/bundle
RUN bundle install --without production development test
ADD . $APP_HOME
ENV PATH ~/bin:$PATH

我当然可以删除所有旧容器：

 docker rm `docker ps -aq`

但我不想在每次启动时都这样做..

这里是 f.ex。三 stop/start

后记录

~/workspace/rcd$ docker-compose up

我认为此问题已在 docker-compose 1.5 中修复。您只会从启动容器时获取日志。

限制 docker-compose 的日志量

limit logs amount for docker-compose
