查看某个命令的使用细节
docker xxx --help
从官方镜像库拉取镜像
docker pull python:3.7
显示本地镜像
docker image list
使用特定镜像启动一个容器,并进入命令行,注意,如果不带/bin/bash会直接启动python,在终端shell下直接输入exit可以退出终端。
docker run -it python:3.7 /bin/bash --name="your name"
注意,不加name选项系统会自动分配一个奇怪的名字给你,类似随机的游戏ID名字, 比如心如磐石的张三
docker run -itd python:3.7 /bin/bash
查看运行中的容器
docker ps -a
这里注意,当你运行一个容器后退出,这个容器虽然停止了,但是容器的实体还在。
启动一个已经穿见过的容器,XXX是容器的ID。如果需要shell交互,加 -i
docker start xxxx
对应的,停止一个容器,依然需要知道ID。
docker stop xxx
运行一个exit后不停止的容器
docker exec -it 243c32535da7 /bin/bash
当你基于某个镜像的容器进行了自己的环境配置后,想要导出你的容器,使用一下步骤
导出一个容器
docker export 861 -o p37numpy.tar
导入一个容器
docker import .\p37numpy.tar py37:numpy
如果需要将镜像直接进行保存和载入,可以使用load和save
docker save 24f00 -o p37.tar
docker load -i .\p37.tar
注意,如果使用了load,那么会替换一样的镜像。
如果是你改了某镜像的容器,并想把这些更改加入到镜像中,使用命令
95是ID, py37numpy是name,928是tag
docker commit -m "add numpy" -a "Yan" 95 py37numpy:928
commit以后就会出现一个新的镜像,可以push这个镜像,这里注意,xxy是你自己的仓库名字
docker push xxy/py37numpy
查看一个镜像的详细信息
docker inspect xxx
查看docker占用内存情况
docker system df
清理空间,慎用!
docker system prune
拷贝主机文件到容器中
docker cp yourfile containerID:targetDir
Linux下docker使用主机显示和网络,也就是可视化图形显示
docker run --net=host --env="DISPLAY"
这里特别要注意一点,在arm上构建的docker镜像可能无法应用于普通的X86电脑。
