pygame NoVNC xvfb
### 流程 #### `浏览器--->noVNC--->xvfb虚拟桌面--->pygame程序` ### xvfb安装 #### 编辑Dockerfile ```bash cat Dockerfile ``` ```bash FROM ubuntu:xenial LABEL maintainer "sheyinsong" EXPOSE 5900 6099 ENV \ DEBIAN_FRONTEND="nonintractive" \ X11VNC_PASSWORD="password" RUN sed -i -e s#security.ubuntu.com#mirrors.aliyun.com#g -e s#archive.ubuntu.com#mirrors.aliyun.com#g /etc/apt/sources.list RUN apt-get update -y RUN apt-get install -y software-properties-common RUN add-apt-repository ppa:jonathonf/python-3.6 RUN apt-get update -y RUN apt-get install -y xvfb x11vnc python3.6 libglib2.0-0 RUN apt-get install -y curl RUN /bin/cp /usr/bin/python3.6 /usr/bin/python RUN curl https://bootstrap.pypa.io/get-pip.py | python3.6 RUN pip install pygame ADD ./start.sh /opt/start.sh ENTRYPOINT [ "bash","/opt/start.sh" ] ``` #### 创建start.sh脚本 ```bash cat start.sh ``` ```bash #!/bin/bash screen_width=${1:-800} screen_height=${2:-600} screen_depth=${3:-16} run_file=${4:-"main.py"} nohup Xvfb :1 -screen 0 ${screen_width}x${screen_height}x${screen_depth} >/dev/null 2>&1 & sleep 0.1 nohup /usr/bin/x11vnc -display :1.0 -passwd ${X11VNC_PASSWORD:-password} >/dev/null 2>&1 & sleep 0.1 DISPLAY=:1.0 export DISPLAY cd /run_game PYTHONIOENCODING=utf-8 python $run_file ``` #### 创建pygame镜像 ```bash docker build -t sheyinsong/pygame:1.0 . ```   ### Novnc安装 #### 编辑Dockerfile ```bash cat Dockerfile ``` ```bash FROM python MAINTAINER sys "sheyinsong" RUN apt-get update -y RUN apt-get upgrade -y RUN apt-get install -y python-numpy RUN apt-get clean RUN pip install redis RUN pip install simplejson ADD ./noVNC/ /noVNC/ CMD ["python", "/noVNC/utils/websockify/run", "--web", "/noVNC", "0.0.0.0:10240", "--target-config", "/noVNC/token.list"] ``` #### 下载noVNC 下载地址:https://github.com/novnc/noVNC/releases/ #### 创建token.list(token映射到对应的socket) ```bash cat noVNC/token.list #noVNC下载好后,到根目录创建该文件 ``` ```bash a35fe7f7fe8217b4369a0af4244d1fca: 127.0.0.1:5000 03b264c595403666634ac75d828439bc: 127.0.0.1:5001 ... ``` #### 创建novnc镜像 ```bash docker build -t sheyinsong/noVNC:1.0 . ``` #### 运行novnc容器 ```bash docker run -d --network="host" --restart=always -it sheyinsong/novnc:1.0 ```   #### 创建生成NoVNC地址的脚本 ```bash cat pygame_url.py ``` ```python #coding:utf-8 import sys import os import random import subprocess import hashlib import time import argparse import json parser = argparse.ArgumentParser() parser.add_argument("pygame_dir",nargs = 1, help="Pygame progrom root directory") parser.add_argument("--screen-width", help="Xvfb screen width,default value 800", default=800, type=int) parser.add_argument("--screen-height", help="Xvfb screen heigth,default value 600", default=600, type=int) parser.add_argument("--screen-depth", help="Xvfb screen depth,default value 16", default=16, type=int) parser.add_argument("--run-file", help="run specify file", default='main.py') args = parser.parse_args() pygame_dir=args.pygame_dir[0] screen_width=str(args.screen_width) screen_height=str(args.screen_height) screen_depth=str(args.screen_depth) run_file=args.run_file pygame_image='sheyinsong/pygame:1.0' sample_url='http://192.168.50.252:10240/vnc_lite.html?path=?token=' #地址为noVNC运行的地址 dict_data={} if not os.path.isdir(pygame_dir): dict_data['result']='error' dict_data['msg']=pygame_dir+'程序目录不存在.' print(json.dumps(dict_data)) exit(1) pygame_main=os.path.join(pygame_dir,'main.py') if not os.path.exists(pygame_main): dict_data['result']='error' dict_data['msg']=pygame_dir+'程序目录不存在文件main.py.' print(json.dumps(dict_data)) exit(1) source = open(pygame_main, 'r').read() + '\n' try: code_obj=compile(source, pygame_main, 'exec') except Exception as e: dict_data['result']='error' dict_data['msg']=str(e) print(json.dumps(dict_data)) exit(1) def get_free_random_port(): command="netstat -ltnp |grep x11vnc|awk '{ print $4}'|awk -F: '{ print $NF}'" p = subprocess.Popen(command,stdout=subprocess.PIPE,stderr=subprocess.STDOUT,shell=True) usage_port_list=[ int(port) for port in p.stdout.read().split('\n') if port != '' ] free_post_list=set(range(5000,6000))-set(usage_port_list) return random.choice(list(free_post_list)) def convert_png(): command="find {0} -name *.png|while read line;do;
