docker容器内使用uwsgi发布服务

清单解析器服务化

1 将项目文件导入服务器

准备好以下文件

（1）Dockerfile-parser

From swr.cn-north-4.myhuaweicloud.com/zt-sjzn-znzj-pd/costestimation-base:3.0 #基础镜像
MAINTAINER "zhanghc" "[email protected]" # 维护人

ENV LC_ALL "zh_CN.UTF-8" #编码环境

COPY serving/ /workspace/serving/ # 将上图中serving中的文件复制到docker容器内

RUN chmod +x /workspace/serving/run.sh # 赋权给run.sh

RUN pip install -i https://ai-sjzn-project:[email protected]/artifactory/api/pypi/PyPI-AIplatform-open/simple --extra-index-url https://pypi.tuna.tsinghua.edu.cn/simple parsercode==2.0.0 #将组件沉淀生成的python包安装到docker容器内

WORKDIR /workspace/serving # 工作路径

ENTRYPOINT ["/workspace/serving/run.sh]

（2）mysql_config.json

配置数据库信息

{
    "host": "192.168.8.51",
  	"user": "root",
  	"password": "123456",
  	"database": "gld_cost_estimation",
  	"port": "3308",
  	"charset": "utf8"
 }

（3）uwsgi_main.py

调用解析器，定义wsgi接口，以供http请求。

# -*- coding:UTF-8 -*-
import os, sys, json
import pandas as pd
import requests

curPath = os.path.abspath(os.path.dirname(__file__))
#rootPath = os.path.split(curPath)[0]
sys.path.append(curPath)
# sys.path.append(os.path.dirname(os.path.dirname(__file__)))

import parser_api.parser_api as pa
dbid='1710'
chapter_code='all'
mysql_config_file=os.path.join(os.path.dirname(__file__),'mysql_config.json')
p=pa.PARSER_API(dbid, chapter_code, mysql_config_file)

def get_result(data):
    ret = p.get_parser_result(data['itemcode'], data['spec_name'], data['spec'])
    #print("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!",ret)
    #return (ret)
    return ret

def application(environ, start_response):
    # 加入logging
    # fileConfig(log_file_path)
    # logger = logging.getLogger(name="TimedRotatingFileHandler")

    try:
        request_body_size = int(environ.get("CONTENT_LENGTH", 0))
    except ValueError:
        request_body_size = 0
        print(f"---request_body_size---: {request_body_size}")
    request_body = environ['wsgi.input'].read(request_body_size)
    print(f"-----request_body------:  {request_body}")
    request_body = json.loads(request_body.decode().strip())
    # print(f"-----after decode,request_body------:  {request_body}")
    print(f"---request name: {request_body['methodname']}")

    ########################deal with request#########################################################
    finalresponse = None
    if request_body['methodname'] == 'hello':
        finalresponse = "Hi, there"
    elif request_body['methodname'] == "get_result":

        # 伟革错误编码可以在这里做修改
        try:
            try:
                # logger.info(request_body)
                finalresponse = get_result(request_body)
            except ValueError:
                finalresponse = {'errorString': 'Wrong formate'}
                # logger.error(finalresponse)
        except:
            finalresponse = {'errorString': 'Unknow Error'}
            # logger.error(finalresponse)

    else:
        print(f"------request_body['methodname']={request_body['methodname']}--------")

    ########################final response#########################################################
    # print(f"finalresponse: {finalresponse}")
    response_body = json.dumps(finalresponse, ensure_ascii=False).encode()
    status = '200 OK'
    response_headers = [
        ('Content-Type', 'application/json'),
        ('Content-Length', str(len(response_body)))
    ]
    start_response(status, response_headers)
    # return [json.dumps(finalresponse).encode()]
    # logger.info(response_body)
    return [response_body]

if __name__ == "__main__":
    print("just a test")

    print("test case 2")

    itemcode = "031001001"
    spec_name = "穿楼板套管"
    spec = "1.名称:穿楼板套管፨2.规格型号:DN100"

    data = {}

    data['itemcode'] = itemcode
    data['spec_name'] = spec_name
    data['spec'] = spec

    res = get_result(data)
    print(res)

（3）uwsgi.conf.ini

uwsgi配置文件

[uwsgi]
http = :9001
chdir = /workspace/costparser/ #工作路径
logto =  /workspace/costparser/log.log #日志
wsgi-file = ./uwsgi_main.py #wsgi文件

master = true
processes = 1 #进程
threads = 2 #线程
stats = 127.0.0.1:9091
pidfile=%(chdir)uwsgi.pid
vacuum = true
enable-threads=true
lazy-apps = true

（4）run.sh

运行uwsgi.conf.ini

#!/bin/bash
/usr/local/python3/bin/uwsgi ./uwsgi.conf.ini

2 创建镜像

#使用当前目录的 Dockerfile 创建镜像，标签为 parsercode:v1。
docker build -t parsercode:v1 . 

#也可以通过 -f Dockerfile 文件的位置：
docker build -f /path/to/Dockerfile-parser .

#查看创建的镜像
docker images | grep parsercode

#删除镜像
docker rmi 镜像ID

3 创建启动容器

docker run -d -it --name test03 -p 9013:9000 parsercode:v1
#此时服务已经启动

#查看容器test03
docker ps | grep test03
#查看所有容器
docker container ls

#查看容器日志
docker logs test03

#停止、删除容器
docker stop test03
docker rm test03

4 进入容器并查看服务进程

#进入容器
docker exec -it exec test03 bash

#查看进程,验证进程是否已启动
ps -ef | grep uwsgi

5 postman请求验证
