Docker部署Nginx+Flask+Mongo的应用介绍（附代码）

#!/bin/bash
mongo <<EOF
use admin;
db.auth('root', '123456');
use dmx_aluminum;
db.createUser({user:'test',pwd:'test',roles:[{role:'readWrite',db:'test'}]});
db.createCollection("user");
EOF

Flask应用的配置

/flask/Dockerfile的内容如下

FROM python:3.6
# 设置时区
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

# 设置工作区
RUN mkdir -p /home/web
WORKDIR /home/web
# 添加依赖
ADD requirements.txt /home/web/requirements.txt
RUN pip3 install -i https://pypi.douban.com/simple/ -r requirements.txt

# 使用gunicorn启动应用
CMD gunicorn -w 4 -b 0.0.0.0:5000 run:app

/src/app/run.py的代码

from app import create_app
app = create_app('default')
app.debug=False
# if __name__ == '__main__':
# app.run()

Nginx的配置

/nginx/Dockerfile的内容如下

FROM nginx:1.14
# 设置时区
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
# 复制配置
COPY conf/nginx.conf /etc/nginx/nginx.conf

/nignx/conf/nginx.conf的内容如下

user nginx;
worker_processes 1;

error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;

events {
 worker_connections 1024;
}


http {
 include /etc/nginx/mime.types;
 default_type application/octet-stream;

 log_format main '$remote_addr - $remote_user [$time_local] "$request" '
 '$status $body_bytes_sent "$http_referer" '
 '"$http_user_agent" "$http_x_forwarded_for"';

 access_log /var/log/nginx/access.log main;

 sendfile on;
 #tcp_nopush on;

 keepalive_timeout 65;

 # 开启gzip
 gzip on;
 gzip_min_length 1k;
 gzip_buffers 4 16k;
 #gzip_http_version 1.0;
 gzip_comp_level 1;
 gzip_types text/plain application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;
 gzip_vary off;
 gzip_disable "MSIE [1-6]\.";

 server {
 listen 80;
 server_name localhost;
 keepalive_timeout 5;
 root /usr/share/nginx/html;

 location /static/ {
 alias /usr/share/nginx/html/src/app/static/;
 }

 location / {
 # checks for static file, if not found proxy to app
 try_files $uri @flask_app;
 }

 location @flask_app {
 proxy_pass http://192.168.0.2:5000; # 发布在阿里云上，应填写内网IP
 proxy_redirect off;
 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 proxy_set_header Host $http_host;
 proxy_set_header X-Real-IP $remote_addr;

 #proxy_buffers 8 32k;
 #proxy_buffer_size 64k;

 }
 }


}

启动部署

1. 进入docker-flie目录 cd docker-flie
2. 启动docker docker-compose up
3. 查看容器状态 docker ps
4. 本地部署浏览器输入 127.0.0.1即可

最后出现类似docker_file_nginx_1,docker_file_mongo_1, docker_file_flask_1的3个容器，说明成功！！！

踩坑吐槽

本人做过如下尝试，会显示 mongdb未启动。

ADD setup.sh /data/setup.sh
RUN chmod +x /data/setup.sh
CMD ["/data/setup.sh"]

在数据库的配置应相应写成：

MONGODB_SETTINGS = {
 'db': 'test',
 'host': 'mongo', # 127.0.0.1 host地址一定要写你配置的--link的名字
 'username': 'test',
 'password': 'test',
 'port': 27017
 }

本地测试时改回127.0.0.1
