mongodb连接被拒绝docker-compose [英] mongodb connection refused docker-compose
问题描述
dockerfile包含以下内容：-
The dockerfile consists as:-
FROM ruby:2.2.3-slim
MAINTAINER Milan Rawal <milan@gmail.com>
RUN apt-get update && apt-get install -qq -y build-essential nodejs libmagickcore-dev imagemagick libmagickwand-dev libxml2-dev libxslt1-dev git-core curl htop --fix-missing --no-install-recommends

VOLUME ["$INSTALL_PATH/public"]
CMD bundle exec unicorn -c config/unicorn.rb
并且docker-compose.yml文件包含以下内容：-
And the docker-compose.yml file contains as:-
version: '2'
services:
mongodb:
image: mongo:latest
ports:
- '27017:27017'
volumes:
- air_scout-mongodb:/data/db

air_scout:

ports:
- '8000:8000'
environment:
- DATABASE_URL=mongodb:27017

resque:

air_scout-mongodb:
当我执行 docker-compose build时，所有东西都会正确构建；当我执行 docker-compose up时，应用程序启动，我能够访问在VM主机上的air_scout容器中运行的应用程序，但可以在数据库访问应用程序上访问该应用程序。页面，我收到以下错误消息：
When I do "docker-compose build" every thing build properly and when I do "docker-compose up" then the app boots and I'm able to access the app running in air_scout container on vm host, but on db access app. page I get error as:
air_scout_1 | [fe9cdec8-36e4-4974-aef3-18b1e73ea030] [DEBUG] MONGODB |连接被拒绝-127.0的connect（2）。 0.1：27017。
"air_scout_1 | [fe9cdec8-36e4-4974-aef3-18b1e73ea030] [DEBUG] MONGODB | Connection refused - connect(2) for 127.0.0.1:27017".
在mongoid.yml文件中，我进行了如下配置：
In my mongoid.yml file I have did config like below:
hosts:
- localhost:27017
- <%= ENV['DATABASE_URL'] %>
实际上是个问题，从昨天开始我真是在头。谢谢。
What actually is the issue, I'm really banging my head since yesterday. Thankyou.
执行 docker inspect CID会给出JSON数据，其中Networsetting下的Ipaddress为为空。如何访问此空IP。
Doing "docker inspect CID" gives the json data in which the Ipaddress under Networsetting is "" empty. How can I access this empty IP.
编辑：-mongoid.yml文件中的内容为：-
- contents in mongoid.yml file is as:-
production:
clients:
default:
database: air_scout_test
hosts:
- localhost:27017
- <%= ENV['DATABASE_URL'] %>
options:
max_pool_size: 1
options:
raise_not_found_error: false
推荐答案
您必须从air_scout容器连接到mongodb：27017而不是127.0.0.1:27017。
You have to connect to mongodb:27017 instead of 127.0.0.1:27017 from your air_scout container.
air_scout容器的链接将为redis和mongodb容器创建/ etc / hosts条目。可以使用这些名称访问链接的服务。
The links for the air_scout container will create /etc/hosts entries for the redis and mongodb containers. The linked services will be reachable under those names.
请参见 https://docs.docker.com/compose/compose-file/#/links
您确实设置了环境变量DATABASE_URL的正确值为mongodb：27017，但错误消息仍然包含127.0.0.1:27017。因此，它尝试连接那里而不是mongodb：27017。我没有使用过Mongoid的经验，但我想您应该只将DATABASE_URL保留下来。如果那行不通，请使用mongodb：27017
You do set an environment variable DATABASE_URL with the correct value mongodb:27017, but the error message still contains 127.0.0.1:27017. So it's trying to connect there instead of mongodb:27017. I have no experience with mongoid but I am guessing you should only leave the line with DATABASE_URL. If that does not work, use mongodb:27017
如果您想查看运行情况，将docker exec插入正在运行的air_scout容器中
If you want to see what is going, docker exec into your running air_scout container
docker ps
# take the exact name of the air_scout container in the output
# i am guessing compose_air_scout but i might be off
docker exec -ti compose_air_scout /bin/bash
cat /etc/hosts
ping mongodb
# maybe try an interactive mongodb client
