DOCKER-DESKTOP
Description
This Dockerfile creates a docker image and once it's executed it creates a container that runs X11 and SSH services.The ssh is used to forward X11 and provide you encrypted data communication between the docker container and your local machine.
Xpra + Xephyr allows to display the applications running inside of the container such as Firefox, LibreOffice, xterm, etc. with recovery connection capabilities. Xpra also uses a custom protocol that is self-tuning and relatively latency-insensitive, and thus is usable over worse links than standard X.
The applications can be rootless, so the client machine manages the windows that are displayed.
Fluxbox and ROX-Filer creates a very minimalist way to manage windows and files.
OBS: The client machine needs to have a X11 server installed (Xpra). See the "Notes" below.
Docker Installation
On Ubuntu:
Docker is available as a Ubuntu PPA (Personal Package Archive), hosted on launchpad which makes installing Docker on Ubuntu very easy.
#Add the PPA sources to your apt sources list.
sudo apt-get install python-software-properties && sudo add-apt-repository ppa:dotcloud/lxc-docker
# Update your sources
sudo apt-get update
# Install, you will see another warning that the package cannot be authenticated. Confirm install.
sudo apt-get install lxc-docker
On Windows:
Requirements:
- Installation Tutorial (http://docs.docker.io/en/latest/installation/windows/)
On Mac OS X:
Requirements:
- Installation Tutorial (http://docs.docker.io/en/latest/installation/vagrant/)
Installation
Building the docker image
$ docker build -t rogaha/docker-desktop git://github.com/rogaha/docker-desktop.git
OR
$ git clone https://github.com/rogaha/docker-desktop.git
$ cd docker-desktop
$ docker build -t [username]/docker-desktop .
Running the docker image created (-d: detached mode, -P: expose the port 22 on the host machine)
$ CONTAINER_ID=$(docker run -d -P [username]/docker-desktop)
Getting the password generated during runtime
$ echo $(docker logs $CONTAINER_ID | sed -n 1p)
User: docker Password: xxxxxxxxxxxx
# where xxxxxxxxxxxx is the password created by PWGen that contains at least one capital letter and one number
Usage
Getting the container's external ssh port
$ docker port $CONTAINER_ID 22
49153 # This is the external port that forwards to the ssh service running inside of the container as port 22
Connecting to the container
Starting the a new session
$ ifconfig | grep "inet addr:"
inet addr:192.168.56.102 Bcast:192.168.56.255 Mask:255.255.255.0 # This is the LAN's IP for this machine
$ ssh docker@192.168.56.102 -p 49153 "sh -c './docker-desktop -s 800x600 -d 10 > /dev/null 2>&1 &'" # Here is where we use the external port
docker@192.168.56.102's password: xxxxxxxxxxxx
$ ./docker-desktop -h
-----------------------------------------------------------
Usage: docker-desktop [-s screen_size] [-d session_number]
-s : screen resolution (Default = 800x600
-d : session number (Default = 10)
-h : help
-----------------------------------------------------------
Attaching to the session started
$ xpra --ssh="ssh -p 49153" attach ssh:docker@192.168.56.102:10 # user@ip_address:session_number
docker@192.168.56.102's password: xxxxxxxxxxxx
If you want to execute rootless programs, you just need to connect to the container via ssh and type:DISPLAY=:[session_number] [program_name] &
Eg. DISPLAY=:10 firefox &

@TOC 一、首先系统安装Debian11.0linux系统，并修改配置信息 1、切换安装源为alibaba debian 11.x (bullseye) 1.1编辑sudo vim /etc/apt/sources.list文件 (需要使用sudo), 在文件最前面添加以下条目(操作前请做好相应备份) deb http://mirrors.aliyun.com/debian/ bullseye

Windows安装docker-desktop，默认下载镜像都会放在C盘导致，C盘占用快速增长，为此需要修改默认存放路径，修改办法是通过wsl来迁移原本的两个发行版docker-desktop和docker-desktop-data，最好在首次安装好docker-desktop就执行。具体操作如下，操作前先停止docker： 查看发行版情况，此时两个都在stopped wsl -l -v --al
-
由于docker-desktop采用了wsl2基础引擎，目前没有开放可视化修改镜像的路径，根据以下步骤可以手动修改镜像路径。 暂停docker wsl --shutdown 导出原有镜像 wsl --export docker-desktop-data d:\docker\data\docker-desktop-data.tar wsl --export docker-desktop d:\d

解决方案 1. 进入C:Program FilesDockerDocker cd "C:Program FilesDockerDocker" DockerCli.exe -SwitchDaemon 2. 将数据备份，对docker进行重置，管理员权限运行cmd执行一下命令 netsh winsock reset
-
管理员方式执行cmd命令 cmd窗口运行 ：netsh winsock reset 接着(重要)： 在cmd窗口右键,点击属性,将使用旧版控制台取消勾选 重启Docker Desktop 完美解决！

一、解决的问题 二、与虚拟机的比较 三、优势 四、使用场景 五、镜像与容器 参考资料 一、解决的问题 由于不同的机器有不同的操作系统，以及不同的库和组件，在将一个应用部署到多台机器上需要进行大量的环境配置操作。 Docker 主要解决环境配置问题，它是一种虚拟化技术，对进程进行隔离，被隔离的进程独立于宿主操作系统和其它隔离的进程。使用 Docker 可以不修改应用程序代码，不需要开发人员学习特定环
