我想讓Docker容器能夠看我的項目並編譯應該編譯的內容。 隨着Sass，我有一些與inotify有關的問題。Docker-compose - Ruby - Compass - inotify
當我嘗試推出：
compass watch --sass-dir /var/www/project/styles/sass/ --css-dir /var/www/project/styles/ -c /var/www/project/styles/config.rb
我得到這個錯誤：
[email protected]:/# compass watch --sass-dir /var/www/lbo_legacy/styles/sass --css-dir /var/www/lbo_legacy/styles/ -c /var/www/lbo_legacy/styles/config.rb --trace
>>> Compass is watching for changes. Press Ctrl-C to Stop.

我已經嘗試過增加RB-inotify的用戶數限制，但仍是同樣的錯誤。
我Dockerfile：
FROM ubuntu:latest
ENV DEBIAN_FRONTEND noninteractive
RUN echo fs.inotify.max_user_watches=500000 | tee -a /etc/sysctl.conf
RUN echo fs.inotify.max_queued_events=500000 | tee -a /etc/sysctl.conf
RUN apt-get --quiet update
RUN apt-get install --yes --no-install-recommends gnupg2 vim wget git curl ca-certificates
# Node.js (and NPM).
RUN curl -sL https://deb.nodesource.com/setup_6.x | bash - \
&& apt-get install --yes nodejs build-essential
#Ruby
RUN apt-get install -y ruby ruby-dev rubygems
# Rake.
RUN gem install --no-rdoc --no-ri rake
#Sass
RUN gem install --no-rdoc --no-ri sass -v 3.4.22
# Compass.
RUN gem install --no-rdoc --no-ri compass
# Bower, Grunt CLI, Gulp.
RUN npm install --global bower grunt-cli gulp
# Clean up.
RUN apt-get autoremove --yes \
&& apt-get clean
如果我跑 「的sysctl -p」：
[email protected]:/# sysctl -p
fs.inotify.max_user_watches = 500000
fs.inotify.max_queued_events = 500000
如果需要的話，我的config.rc（但有或沒有-c參數相同的行爲.. 。）
require 'compass/import-once/activate'
# Require any additional compass plugins here.
add_import_path "../assets/zurb_mail/node_modules/foundation-emails/scss"
# Set this to the root of your project when deployed:
http_path = "/"
css_dir = "."
sass_dir = "sass"
images_dir = "images"
javascripts_dir = "javascripts"
# You can select your preferred output style here (can be overridden via the command line):
# output_style = :expanded or :nested or :compact or :compressed
output_style= :compressed
# To enable relative paths to assets via compass helper functions. Uncomment:
# relative_assets = true
# To disable debugging comments that display the original location of your selectors. Uncomment:
# line_comments = false
# If you prefer the indented syntax, you might want to regenerate this
# project again passing --syntax sass, or you can uncomment this:
# preferred_syntax = :sass
# and then run:
# sass-convert -R --from scss --to sass sass scss && rm -rf sass && mv scss sass
它適用於我的Ubuntu主機壽精...
任何想法傢伙？
