我正在嘗試爲我的節點應用程序創建一個容器。這個程序使用MongoDB確保一些數據持久性。 所以我創造了這個Dockerfile:Docker - Node.js + MongoDB - 「錯誤:無法連接到[localhost:27017]」
FROM ubuntu:latest
# --- Installing MongoDB
# Add 10gen official apt source to the sources list
RUN apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
RUN echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | tee /etc/apt/sources.list.d/10gen.list
# Hack for initctl not being available in Ubuntu
RUN dpkg-divert --local --rename --add /sbin/initctl
RUN ln -s /bin/true /sbin/initctl
# Install MongoDB
RUN apt-get update
RUN apt-get install mongodb-10gen
# Create the MongoDB data directory
RUN mkdir -p /data/db
CMD ["usr/bin/mongod", "--smallfiles"]
# --- Installing Node.js
RUN apt-get update
RUN apt-get install -y python-software-properties python python-setuptools ruby rubygems
RUN add-apt-repository ppa:chris-lea/node.js
# Fixing broken dependencies ("nodejs : Depends: rlwrap but it is not installable"):
RUN echo "deb http://archive.ubuntu.com/ubuntu precise universe" >> /etc/apt/sources.list
RUN echo "deb http://us.archive.ubuntu.com/ubuntu/ precise universe" >> /etc/apt/sources.list
RUN apt-get update
RUN apt-get install -y nodejs
# Removed unnecessary packages
RUN apt-get purge -y python-software-properties python python-setuptools ruby rubygems
RUN apt-get autoremove -y
# Clear package repository cache
RUN apt-get clean all
# --- Bundle app source
ADD . /src
# Install app dependencies
RUN cd /src; npm install
EXPOSE 8080
CMD ["node", "/src/start.js"]
然後,我通過建造和發射了整個事情:
$ sudo docker build -t aldream/myApp
$ sudo docker run aldream/myApp
但機器顯示以下錯誤:
[error] Error: failed to connect to [localhost:27017]
任何想法我做錯了什麼?謝謝!
感謝您的回答!我不喜歡容器是單一過程的事實。我選擇了Supervisor,儘管我目前也正在爲mongoDB和我的應用程序構建單獨的容器,以使它更加模塊化...... – Aldream
