1.绑定挂载主机上的目录

        1.准备源代码目录并切换到 source 目录

[root@host1 ~]# mkdir -p source/target && cd source

        2.启动容器并将主机上的 source/target 目录挂载到容器的 /app 目录中

[root@host1 source]# docker run -dit --name devtest --mount type=bind,source="$(pwd)"/target,target=/app nginx
1599e5dd1b6e6f86c7f32f7648552e9b4193ac8a5a1fa17f076d10c4cb410dd4

        3.查看该容器的详细信息

[root@host1 source]# docker inspect devtest

[root@host1 source]# docker stop devtest && docker rm devtest
devtest
devtest

        5.实现只读绑定挂载

[root@host1 source]# docker run -d -it --name devtest --mount type=bind,source="$(pwd)"/target,target=/app,readonly nginx

        7.停止并删除实验所用的容器

[root@host1 source]# docker stop devtest && docker rm devtest
devtest
devtest

2.绑定挂载主机上的文件

[root@host1 ~]# docker run --rm -it -v/etc/localtime:/etc/localtime ubuntu /bin/bash
root@cf8eceac7f76:/# date -R
Fri, 12 Sep 2025 14:56:13 +0800
root@cf8eceac7f76:/# exit
exit

3.绑定挂载主机上不存在的目录或文件

[root@host1 ~]# docker run --rm -v /doesnt/exist:/foo -w /foo -i -t ubuntu bash
root@93e7e5614d4d:/foo# exit
exit
[root@host1 ~]# ls -l /doesnt
总用量 0
drwxr-xr-x. 2 root root 6  9月 12 15:00 exist

4.绑定挂载到容器中的非空目录

[root@host1 ~]# docker run -d -it --name broken-container --mount type=bind,source=/tmp,target=/usr nginx
649c895a6159a2d6d002f328faa311a480c10e7d613bbd5a0041e162e13f4392
[root@host1 ~]# docker container rm broken-container
broken-container
