docker操作指南

Docker 容器连接 | 菜鸟教程 (runoob.com)

1.为了使pycharm可以通过ssh链接到docker容器，我们需要为docker容器分配端口，分配端口的命令如下：

C:\Windows\system32>docker run --name ubuntu-test  -it -p 6767:80 ubuntu:latest

2.2把容器保存为镜像

C:\Windows\system32>docker ps -a
CONTAINER ID   IMAGE           COMMAND   CREATED          STATUS                     PORTS     NAMES

C:\Windows\system32>docker images
REPOSITORY   TAG       IMAGE ID       CREATED          SIZE

3.docker目录映射

#创建映射目录命令

C:\Windows\system32>docker run --name conda-v1 -v C:\Users\WZ\Desktop\conda:/data -it ubuntu:latest

进入目录命令
root@1c0ae099dba0:/# cd /data/

查看目录文件
root@1c0ae099dba0:/data# ll
total 4
drwxrwxrwx 1 root root    0 Oct 14 17:38 ./
drwxr-xr-x 1 root root 4096 Oct 14 17:42 ../

在映射目录 创建文件
root@1c0ae099dba0:/data# mkdir hellow-docker
root@1c0ae099dba0:/data# ll
total 4
drwxrwxrwx 1 root root    0 Oct 14 17:44 ./
drwxr-xr-x 1 root root 4096 Oct 14 17:42 ../
drwxrwxrwx 1 root root    0 Oct 14 17:44 hellow-docker/

4.docker+ubuntu，安装anaconda

将下载的conda 镜像复制到主机目录

root@e3155ddfb4ac:/data# bash Anaconda3-2022.05-linux-x86_64.sh

(17条消息) Ubuntu系统anaconda安装初始化和env环境切换_柏常青的博客-CSDN博客_anaconda 初始化

5.进入conda环境

#命令

root@c07d5cb47355:/# source ~/anaconda3/bin/activate
 
#结果

(base) root@c07d5cb47355:/# 

6.也许的地址

(base) root@c07d5cb47355:/# anaconda-navigator
Traceback (most recent call last):
  File "/root/anaconda3/bin/anaconda-navigator", line 7, in 
    from anaconda_navigator.app.main import main
  File "/root/anaconda3/lib/python3.9/site-packages/anaconda_navigator/app/main.py", line 19, in 
    from anaconda_navigator.app.start import start_app
  File "/root/anaconda3/lib/python3.9/site-packages/anaconda_navigator/app/start.py", line 17, in 
    from qtpy.QtGui import QIcon

    from PyQt5.QtGui import *
ImportError: libGL.so.1: cannot open shared object file: No such file or directory

7.查看 conda的虚拟环境

(base) root@c07d5cb47355:/# conda env list
# conda environments:
#
base                  *  /root/anaconda3

8.查看系统现在的环境变量

root@c07d5cb47355:/# source ~/anaconda3/bin/activate

(base) root@c07d5cb47355:/# echo $PATH
/root/anaconda3/bin:/root/anaconda3/condabin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

9.密钥

(base) root@2d266a8bf1be:/# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa
Your public key has been saved in /root/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:cu2W93w7/ytuSz18O3GDFBabtibH6HHaBG8lsDsalsI root@2d266a8bf1be
The key's randomart image is:
+---[RSA 3072]----+

10.安装pytorch-cpu

#可以在pytorvh官网选择合适的版本，

conda install pytorch-cpu torchvision-cpu -c pytorch

#完成后检验是否有错误：

    python
    import torch
    import torchvision

#若没有报错则完成。
