Kubernetes生产实践系列之四：在Kubernetes运行带Desktop的Ubuntu容器

ゝ一世哀愁。 2023-05-22 22:41 709阅读 0赞

## **一、前言** ##

在文章[《Kubernetes生产实践系列之二：在Kubernetes使用kubevirt运行管理Ubuntu/Windows桌面操作系统》][Kubernetes_Kubernetes_kubevirt_Ubuntu_Windows]中，我们部署来虚拟机并提供桌面来向Kubernetes的用户提供带桌面的运行环境，这种用受Kubernetets管理虚拟机来部署桌面的方式一方面对于Kubernetets节点的虚拟化提出要去，另外方面，也是比较重的解决方案。本文介绍通过容器运行Ubuntu Desktop并通过Kubernetets进行部署提供桌面运行环境的方案。

## **二、获取代码** ##

获取带桌面的ubuntu docker镜像代码

git clone https://github.com/fcwu/docker-ubuntu-vnc-desktop.git
    cd docker-ubuntu-vnc-desktop-master/

获取依赖软件

wget https://github.com/krallin/tini/releases/download/v0.18.0/tini
    wget https://johnvansickle.com/ffmpeg/releases/ffmpeg-release-64bit-static.tar.xz

获取noVNC和websockify

cd web/static
    git clone https://github.com/novnc/noVNC.git
    git clone https://github.com/novnc/websockify.git

## **三、构建镜像并运行docker** ##

### 3.2 构建镜像 ###

docker build -t ubuntu_desktop_base -f Dockerfile .

### 3.3 运行容器并且访问VNC桌面 ###

docker run -dt --rm -p 8080:80 ubuntu_desktop_base

## **四、在Kubernetes部署** ##
