Question

运行docker-compose build＆amp;＆amp;＆amp;＆amp;＆amp; docker-compose up并试图点击我的索引页面：

[crit] 8#8: *1 connect() to unix:/tmp/uwsgi.sock failed (2: No such file or directory) while connecting to upstream, client: 192.168.99.1, server: localhost, request: "GET / HTTP/1.1", upstream: "uwsgi://unix:/tmp/uwsgi.sock:", host: "192.168.99.100"

这是我的docker-compose.yml：

web:
  restart: always
  build: ./web-app
  expose:
    - "8000"
  command: /usr/local/bin/uwsgi --ini sample-uwsgi.ini

nginx:
  restart: always
  build: ./nginx/
  ports:
    - "80:80"
  links:
    - web:web

的nginx / Dockerfile

FROM nginx
RUN rm /etc/nginx/conf.d/default.conf
ADD sample-nginx.conf /etc/nginx/conf.d/

的nginx /采样nginx.conf

server {

    listen 80;
    server_name localhost;
    charset utf-8;
    client_max_body_size 75M;

    location / {
        include uwsgi_params;
        uwsgi_pass unix:/tmp/uwsgi.sock;
    }
}

web的应用程序/ Dockerfile

FROM ansible/ubuntu14.04-ansible:stable

WORKDIR /root
ADD application.py application.py
ADD requirements.txt requirements.txt
ADD sample-uwsgi.ini sample-uwsgi.ini

ADD ansible /srv/ansible
WORKDIR /srv/ansible

RUN ansible-playbook container-bootstrap.yml -c local

web的应用程序/样品uswgi.ini

[uwsgi]

module = application
callable = app

master = true
processes = 5

socket = /tmp/uwsgi.sock

chown-socket = www-data:www-data

vacuum = true
enable-threads=True
die-on-term = true

更新

根据@kryten的建议，我将使用TCP / IP

更新了nginx.conf：

server {

    listen 80;
    server_name localhost;
    charset utf-8;
    client_max_body_size 75M;

    location / {
        uwsgi_pass localhost:8000;
        include uwsgi_params;
    }
}

更新了uwsgi.ini：

[uwsgi]

module = application
callable = app

master = true
processes = 5

socket = localhost:8000

chown-socket = www-data:www-data

vacuum = true
enable-threads=True
die-on-term = true

现在正在追究以下错误：

[error] 8#8: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.99.1, server: localhost, request: "GET / HTTP/1.1", upstream: "uwsgi://127.0.0.1:8000", host: "192.168.99.100"

Answer 1

由于web和nginx是单独的容器，因此nginx需要通过TCP连接到另一台计算机。 Linking the containers已完成大部分工作，您只需将上游指向web:8000而不是localhost。

Answer 2

您的某个应用程序似乎试图通过Unix socket而不是通过TCP / IP进行连接。

这不适用于不同的容器，因为在另一个容器中无法访问一个容器（套接字所在的容器）中的文件系统。

解决方案是重新配置您的应用程序以通过TCP / IP而不是Unix套接字进行连接。

可能可以通过将套接字所在的文件系统中的位置暴露给另一个容器来连接，但我从来没有尝试过这个＆amp;不知道它是否会起作用。

Docker容器遇到套接字问题（单独的Flask + Nginx容器）
