docker常用指令

一、目录

1. docker 指令
   1. 创建镜像
   2. 保存镜像
   3. 加载镜像
   4. 删除容器
   5. 删除镜像
   6. 查看容器日志
   7. 查看docker 占用内存情况
   8. 查看docker 根目录(安装路径)
   9. 创建一个容器

二、实现

1. docker指令
   1 创建镜像

   docker commit  fd69960ed65f  jyf：0.0.1

2. 保存镜像

   docker save -o my.tar hello-word:latest

3. 加载镜像

   docker load -i my.tar

4. 删除容器

   docker rm CONTAINER-ID #删除容器id, 或者>>docker rm name #容器名字
   批量删除
   docker rm $(docker ps -a -q)

5. 删除镜像

   docker rmi image-id #删除镜像id

6. 查看容器日志

   docker logs CONTAINER-ID #容器id

7. 查看docker 占用内存情况

   [root@localhost ~]# docker system df
   TYPE TOTAL ACTIVE SIZE RECLAIMABLE
   Images 81 41 37.12GB 18.87GB (50%)
   Containers 58 18 33.98GB 32.39GB (95%)
   Local Volumes 42 25 1.598GB 1.492GB (93%)
   Build Cache 130 0 562.7MB 562.7MB

8. 查看docker 根目录(安装路径)

9. 创建一个容器

   镜像选取：docker pull pytorch/pytorch:1.9.1-cuda11.1-cudnn8-devel
   docker run -it --gpus '"device=1,2"' --name leinao -v /tmp:/tmp pytorch/pytorch:pytorch:1.9.1-cuda11.1-cudnn8-devel /bin/bash
   docker run -it --gpus '"device=2,3"' -v /jiayafei_linux/:/home/ --name llm_g pytorch/pytorch:2.1.0-cuda12.1-cudnn8-devel /bin/bash

   docker run -it --gpus '"device=0"' -v /jiayafei_linux/:/home/ --name nodes_0 -p8201:8010 pytorch/pytorch:2.1.0-cuda12.1-cudnn8-devel /bin/bash
   docker run -it --gpus '"device=1"' -v /jiayafei_linux/:/home/ --name nodes_1 -p8202:8010 pytorch/pytorch:2.1.0-cuda12.1-cudnn8-devel /bin/bash

   docker run -it --gpus all --name llm-01 -v /:/home -p8011:8011 -p8012:8012 -p8013:8013 -p8014:8014 pytorch/pytorch:2.1.0-cuda12.1-cudnn8-devel /bin/bash
