circus && web comsole docker-compose 独立部署

问题的根本原因是web console 的bug（实际上还是python 对于依赖版本出来不明确）

circus 进程docker 镜像

• dockerfile

FROM python:slim-stretch

LABEL AUTHOR="dalongrong"

LABEL EMAIL="1141591465@qq.com"

WORKDIR /app

RUN apt-get update && apt-get install -y --reinstall build-essential \

    && pip install circus chaussette \

    && apt-get remove -y --purge build-essential \

    && rm -rf /var/lib/apt/lists/*

COPY circus.ini /app/

COPY entrypoint.sh /entrypoint.sh

RUN chmod +x /entrypoint.sh

ENTRYPOINT [ "/entrypoint.sh" ]

• entrypoint.sh

#!/bin/sh

circusd /app/circus.ini

• circus demo 配置文件

[circus]

statsd = True

​

[watcher:webapp]

cmd = /usr/local/bin/chaussette --fd $(circus.sockets.web)

numprocesses = 5

use_sockets = True

​

[socket:web]

host = 0.0.0.0

port = 9999

circus web console docker 镜像

• dockerfile

  说明因为pyzmq 以及tornado 版本的问题，进行了特殊处理

FROM python:2.7-slim-stretch

LABEL AUTHOR="dalongrong"

LABEL EMAIL="1141591465@qq.com"

RUN apt-get update && apt-get install -y --reinstall build-essential \

    && pip install circus-web \

    && pip uninstall -y tornado \

    && pip uninstall -y pyzmq \

    && pip install tornado==3.2.2 \

    && pip install pyzmq==16.0.4 \

    && apt-get remove -y --purge build-essential \

    && rm -rf /var/lib/apt/lists/*

COPY entrypoint.sh /entrypoint.sh

RUN chmod +x /entrypoint.sh

ENTRYPOINT [ "/entrypoint.sh" ]

• entrypoint

#!/bin/sh

circushttpd

集成试用

使用docker-compose

• docker-compose 文件

version: "3"

services: 

  circus:

    image: dalongrong/circus:3.7-slim-stretch

    ports: 

    - "9999:9999"

    - "5555:5555"

    volumes: 

    - "./circus.ini:/app/circus.ini"

  circus-web:

    image: dalongrong/circusd-web:2.7-slim-stretch

    ports:

    - "8080:8080"

• circus 配置文件

  数据卷挂载方式

[circus]

statsd = True

check_delay = 5

endpoint = tcp://0.0.0.0:5555

pubsub_endpoint = tcp://0.0.0.0:5556

stats_endpoint= tcp://0.0.0.0:5557

​

[watcher:webapp]

cmd = /usr/local/bin/chaussette --fd $(circus.sockets.web)

numprocesses = 5

use_sockets = True

​

[socket:web]

host = 0.0.0.0

port = 9999

启动&&效果

• 启动

docker-compose up -d

• socket 访问

• web console 访问

说明

因为web console 获取circus stats 接口地址错误（bug），造成无法获取进行的统计信息，只能进行操作处理,同时这种处理方式并不是很安全，实际推荐
基于ipc 通信，并通过ssh tunneling 进行管理以及通信信息查看
