Docker CI: 基于 Dockerfile 构建 WebTestbed 新镜像

一、概述

基于 Docker 集成 CI 环境。涉及技术：Linux（Ubuntu 14.04）, Docker, Jenkins, Git/Gitlab, Web/Httpbin, Python/Pytest, UI/Selenium, Robotframework, Grid Server, Appium 等。

架构图如下：

二、Docker 平台（Ubuntu 14.04）：基于 Dockerfile 构建 WebTestbed 新镜像

# cd /vm/docker/robotframework
# sudo docker build -t rf .

三、查看并运行 WebTestbed 镜像

--name：容器名
--restart：自动启动
--shm-size：内存大小，1g 防止浏览器 crashed
-d：daemon 守护进程
-p：publlish 端口，5901是 webtest VNC 端口，1022 是 SSH 端口

# sudo docker images
# sudo docker run --name webtest --restart always --shm-size=1g -d -p 5901:5901 -p 1022:22 rf
# sudo docker ps

四、VNC Viewer 打开容器 webtest
