docker 安装

 
添加软件源，需要提前配置好 yum
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
ll /etc/yum.repos.d/
total 12
-rw-r--r--. 1 root root 2323 Jun 16 17:53 CentOS-Base.repo
-rw-r--r--. 1 root root 2640 Jun 17 19:25 docker-ce.repo
-rw-r--r--. 1 root root  358 Jun 16 17:52 redhat.repo

添加必要的依赖
yum install -y yum-utils device-mapper-persistent-data lvm2

更新并安装 Docker-CE
yum makecache fast
yum -y install docker-ce

开启Docker服务
systemctl start docker
这个命令会在/var/lib目录下创建一个docker目录
后续导入的镜像，生成的容器等文件会存这个目录下

linux

root@ai:~# docker --version
Docker version 24.0.5, build 24.0.5-0ubuntu1~22.04.1

二、Docker19.03之后，内置gpu支持****

增加了对–gpus选项的支持，我们在docker里面想读取nvidia显卡再也不需要额外的安装nvidia-docker2了。需要提前禁用nouveau：lsmod | grep nouveau没有输出即禁用了

需要安装：
1.安装nvidia驱动、cuda 
root@ai:~# ll /usr/local/cuda
lrwxrwxrwx 1 root root 22  5月  9 15:40 /usr/local/cuda -> /etc/alternatives/cuda/


2、安装nvidia-container-runtime  
3、安装docker-19.03

1、安装驱动和cuda：

下载对应版本的cuda：CUDA Toolkit 12.1 Update 1 Downloads | NVIDIA Developer
比如我下载的为Centos7版本的RPM包，下载后直接安装。安装cuda的时候会自动安装nvidia驱动，控制台信息：

Installing the NVIDIA display driver…

Installing the CUDA Toolkit in /usr/local/cuda-9.1 …

ps:也可以先手动安装驱动，然后再通过.run文件安装cuda（可以选择不安装nvidia驱动）

安装cuda时报错：错误：软件包xxx需要：opencl-filesystem、ocl-icd

解决：安装epel数据源即可yum install epel-release –y。

2、安装nvidia-container-runtime：

distribution=$(. /etc/os-release;echo I D ID IDVERSION_ID)

curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.repo | sudo tee /etc/yum.repos.d/nvidia-docker.repo

sudo yum install -y nvidia-container-toolkit nvidia-container-runtime

3、运行容器时，添加**–**gpu参数启用gpu支持。
使用所有GPU

$ docker run --gpus all nvidia/cuda:9.0-base nvidia-smi
使用两个GPU

$ docker run --gpus 2 nvidia/cuda:9.0-base nvidia-smi
指定GPU运行

$ docker run --gpus ‘“device=1,2”’ nvidia/cuda:9.0-base nvidia-smi

$ docker run --gpus ‘“device=UUID-ABCDEF,1”’ nvidia/cuda:9.0-base nvidia-smi

docker exec -it centos  #进入容器

nvidia-smi #容器内查看gpu使用情况

测试：docker pull ufoym/deepo:keras-py36-cu80  #拉取支持gpu的keras & tensorflow环境

docker run --gpus all --rm -it ufoym/deepo:keras-py36-cu80  #启动后，进入容器。

进入python环境 (docker run --gpus all --rm -it ufoym/deepo)

  你遇到的错误：

  ```
  docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": dial tcp 31.13.92.5:443: i/o timeout
  ```
  
  这是**Docker 无法连接到官方镜像仓库 Docker Hub** 的典型表现，通常是**网络受限**（如防火墙、代理、DNS问题）导致的。
  
  ---
  
  ### ✅ **解决方案一：配置 Docker 使用代理（推荐）**
  
  如果你本地或服务器上有可用的代理（如 Clash、V2Ray、Shadowsocks 等），可以明确告诉 Docker 使用它：
  
  #### ✅ 步骤如下：
  
  ```bash
  # 1. 创建 Docker 的 systemd 配置目录
  sudo mkdir -p /etc/systemd/system/docker.service.d
  
  # 2. 编辑代理配置文件
  sudo nano /etc/systemd/system/docker.service.d/http-proxy.conf
  ```
  
  #### ✅ 添加内容（假设代理端口为 7890）：
  
  ```ini
  [Service]
  Environment="HTTP_PROXY=http://127.0.0.1:7890"
  Environment="HTTPS_PROXY=http://127.0.0.1:7890"
  Environment="NO_PROXY=localhost,127.0.0.1"
  ```
  
  > 如果你的代理运行在局域网其他设备上，请替换为对应 IP。
  
  #### ✅ 应用配置并重启 Docker：
  
  ```bash
  sudo systemctl daemon-reload
  sudo systemctl restart docker
  ```
  
  #### ✅ 验证是否生效：
  
  ```bash
  docker info | grep -i proxy
  ```
  
  输出应包含你配置的代理地址。
  
  ---
  
  ### ✅ **解决方案二：配置国内镜像加速源（辅助）**
  
  即使配置了代理，也建议**同时配置国内镜像源**，加速访问：
  
  ```bash
  sudo nano /etc/docker/daemon.json
  ```
  
  添加内容：
  
  ```json
  {
    "registry-mirrors": [
      "https://registry.docker-cn.com",
      "https://docker.mirrors.ustc.edu.cn",
      "https://mirror.baidubce.com"
    ]
  }
  ```
  
  然后重启 Docker：
  
  ```bash
  sudo systemctl daemon-reload
  sudo systemctl restart docker
  ```
  
  ---
  
  ### ✅ **解决方案三：临时绕过网络问题（手动拉取镜像）**
  
  如果你**无法配置代理或镜像源**，可以：
  
  1. 在**能联网的机器上**（如你的笔记本）：
     ```bash
     docker pull python:3.11
     docker save python:3.11 -o python.tar
     ```
  
  2. 将 `python.tar` 拷贝到目标服务器：
     ```bash
     docker load -i python.tar
     ```
  
  ---
  
  ### ✅ 总结建议
  
  | 场景 | 推荐做法 |
  |------|-----------|
  | 有代理可用 | 直接配置 Docker 使用代理 |
  | 无代理但有网络 | 配置国内镜像源 |
  | 完全断网 | 手动 `docker save/load` 镜像 |
  
  ---
  
  如果你能告诉我你使用的代理类型（如 Clash、V2Ray、Surge、Trojan 等）和运行平台（Linux/macOS/Windows），我可以给你更具体的配置模板。

 

crash 允许局域网代理

mkdir -p /etc/systemd/system/docker.service.d

vim /etc/systemd/system/docker.service.d/http-proxy.conf
[Service]
Environment="HTTP_PROXY=http://192.168.0.43:7890"
Environment="HTTPS_PROXY=http://192.168.0.43:7890"
Environment="NO_PROXY=localhost,127.0.0.1"

如果你是本机运行 Clash，可以使用 127.0.0.1:7890，但推荐用局域网 IP，以便其他机器也能用。

 
sudo systemctl daemon-reload
sudo systemctl restart docker
  
root@qisan:~# docker info | grep -i proxy
 HTTP Proxy: http://192.168.0.43:7890
 HTTPS Proxy: http://192.168.0.43:7890
 No Proxy: localhost,127.0.0.1

docker 修改目录

安装前修改

 
ln -s /data/app/docker /var/lib/docker

更重要/方便的是，
如果之前有一套docker正在用，那么先关闭docker，备份/var/lib/docker目录
迁移/重装OS之后，再将之前备份的/var/lib/docker目录映射回来，
就跟原来的一模一样

安装后修改

 
docker会下载容器，运行会挂载磁盘，所以我们需要把docker装在大容量的分区。

docker info  #查看docker的基本信息
#停止docker服务
systemctl stop docker


#备份原目录
systemctl stop docker
cp -r /var/lib/docker  /opt/app/docker
mv /var/lib/docker /var/lib/docker.bak
ln -s /opt/app/docker /var/lib/docker
systemctl start docker

如果是WSL，即在WSL中安装docker,
不允许使用外挂目录，即无法将插入电脑的移动硬盘，挂载到docker上了

docker 保存容器

docker save -o  py1_1.tar   04940cdcebdf
或
docker save -o py1.tar py1:1

删除
dcoker rmi 04940cdcebdf
 
导入py1_1.tar，需要重新命名
docker load -i py1_1.tar 

重新起个名字
docker tag 04940cdcebdf py1:1

删除
dcoker rmi 04940cdcebdf

导入py1.tar，不需要重新命名，因为导出时带名称了
docker load -i py1.tar

centos7 容器创建示例

指定网段

为docker划分一个子网段，仅限于该服务器内使用
docker network rm  mydk
docker network create --subnet=192.168.73.0/24 mydk

docker run -itd --name pt1 -h pt1 --net mydk --ip 192.168.73.111 -v /opt:/opt/  -v /tmp:/tmp cent7 bash
docker exec -it pt1 bash

拥有systemctl使用权限

 
docker run -itd --privileged --name py1 -h py1 --net mydk --ip 192.168.73.73 -v /opt:/opt -v /tmp:/tmp cent7  /usr/sbin/init
docker exec -it py1 bash

与主机共享IP+端口映射

 
docker run -itd --name py1.1 -h py1.1 --net=host -p 3000:3000  -p 8888:8888 -p 8080:8080 -p 8000:8000 -p 8008:8008 -v /opt:/opt -v /tmp:/tmp -v /media:/media  py1:1  bash

root@ai1:~# docker ps -a
CONTAINER ID   IMAGE     COMMAND            CREATED          STATUS          PORTS     NAMES
79f3308df2cd   py1:1     "bash"             31 seconds ago   Up 29 seconds             py1.1

docker exec -it py1.1 bash

外挂磁盘映射

 
docker run -itd --name py1.2 -h py1.2 --net=host -p 8888:8888 -p 8080:8080 -v /opt:/opt -v /tmp:/tmp -v /media:/media py1:3  bash

-v /media:/media，这里是ubantu系统，这种方式直接将插入ubantu系统的磁盘，映射到了docker中 

如果有独立的IP，可以使用nfs挂载远程的目录
docker run -itd --privileged --name py1 -h py1 --net mydk --ip 192.168.73.73 -v /opt:/opt -v /tmp:/tmp -v /media:/media py1:3  bash

容器创建记录

 
与主机共享IP，不必再设置端口映射，docker用的就是主机的端口，
docker run -itd --privileged --name py1 -h py1 --net=host -v /opt:/opt -v /tmp:/tmp -v /media:/media -v /data:/data py1:1  bash

docker run -itd --privileged --name k2 -h k2 --net=host -v /tmp:/tmp -v /media:/media kaldi:2  bash

日常前端开发环境：包含NodeJs,python 等 
docker commit -m "nodejs and python env" -a "tanpf" a7b77c5f1c80 dev:1
docker save -o /data/docker/dev_1.tar dev:1

docker commit -m "kaldi open" -a "tanpf" 8d90fe5b5da9 kaldi:1

kaldi创建记录

vscode访问docker

 
在windows自带的ubuntu环境上创建一个docker，
-p 22001:22
把ubantu的上22001映射到docker中ssh默认的22端口，
连接ubantu上的22001即连接到docker

root@qisan:/data/jupyter# cd /mnt/d/soft/
root@qisan:/mnt/d/soft# docker load -i docker/ubantu20.tar
867d0767a47c: Loading layer [==================================================>]  75.14MB/75.14MB
Loaded image: ubuntu:20.04 

root@qisan:/mnt/d/soft# docker images|grep ubuntu
ubuntu                   20.04       ff0fea8310f3   2 years ago     72.8MB

由于多添加几个端口映射,后续若端口不够用，可以配置nginx转发
docker run -itd --privileged --name a11 -h a11  --gpus all -p 22001:22 -p 8009:8009 -p 8008:8008 -p 8000:8000 -p 9000:9000 -p 8888:8888 -p 9999:9999  -v /opt:/opt  -v /data:/data -v /tmp:/tmp -v /mnt:/mnt -e NVIDIA_DRIVER_CAPABILITIES=compute,utility -e NVIDIA_VISIBLE_DEVICES=all ubuntu:20.04  bash

apt update 
apt install net-tools vim pkg-config  git  ntpdate  libncurses5  libxft-dev curl
6 31
apt install build-essential
apt install cmake sudo

 
docker run --gpus all -it -d --shm-size=1g --name cm_syfang -v /home/host/xxxx:/home/container/xxxx -p 8022:22 repository:tag

命令 --gpus all 表示容器内可以使用所有 gpu 设备

命令 --gpus “device=0,1”表示使用第一和第二个 gpu 设备

命令 -it 表示进入 docker 之后使用命令行交互

命令 -d 表示后台运行

命令 --shm-size=1g 调整容器共享内存大小

命令 --name attack_liujun 给 docker 容器命名

命令 -v [主机目录]:[容器目录] 挂载数据卷，实现数据的共享和持久化，注意使用绝对路径方式

挂载目录的优点 1.实现数据备份；2.方便数据传输

命令 -p xxxx:22 此时便做了主机端口 8022 与容器端口 22 的映射，可以通过这个端口连接到远程的服务器

安装 ssh 服务

 
sudo apt-get install openssh-server

设置 root 用户密码（设置 root 用户密码为: admin（尽量使用统一的密码））
passwd root

在容器内修改 ssh 配置文件
输入指令
sudo vim /etc/ssh/sshd_config

修改 ssh 配置文件

命令 i: 表示在当前光标位置进入输入模式

在末尾“插入模式”添加下面内容：
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
PermitRootLogin yes

按“Esc”取消“插入模式”，并输入 :wq 保存并退出



启动 ssh 服务
sudo /etc/init.d/ssh start

重启 ssh
service ssh restart

sudo service ssh status

端口映射方式

 
apt install net-tools
ifconfig
ssh -p 22001 root@172.31.150.83

 
如果是开发好一些服务，供他人方便调用时，可提前映射端口，

但若是开发环境，不知道有哪些端口时，
这些端口如果没有提前映射，
那么还需要重新创建docker以映射端口，可以提前多创建几个端口映射

 
sudo apt-get update
sudo apt-get install nginx
sudo systemctl start nginx  
sudo systemctl enable nginx
sudo ufw allow 80

 
定位Nginx配置文件：
Nginx的主配置文件通常位于/etc/nginx/nginx.conf，
但更常见的做法是在/etc/nginx/sites-available/目录下创建或修改配置文件，
然后将其链接到/etc/nginx/sites-enabled/目录。

vim /etc/nginx/sites-available/default

jupyter端口转发示例

 
root@qisan:/etc/nginx/sites-available# cat default
server {
        listen 80 default_server;
        listen [::]:80 default_server;

        root /var/www/html;

        # Add index.php to the list if you are using PHP
        index index.html index.htm index.nginx-debian.html;

        server_name _;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }

        location /pt11 {
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_pass http://172.17.0.2:8888;
        }
}

 
cat ~/.jupyter/jupyter_notebook_config.py
c.NotebookApp.ip='*'
c.NotebookApp.open_browser=False
c.NotebookApp.port=8888
c.NotebookApp.base_url = '/pt11/'

重点是
c.NotebookApp.base_url = '/pt11/'

 
nginx -t 
systemctl restart nginx
