docker使用报错记录

1. Error response from daemon: Mounts denied:

Error response from daemon: Mounts denied:
The path /media is not shared from the host and is not known to Docker.
You can configure shared paths from Docker -> Preferences… -> Resources -> File Sharing.
See https://docs.docker.com/ for more info.

解决方法：
在 Docker -> Preferences… -> Resources -> File Sharing.中添加相应路径，根据报错中给出路径： /media ，点击+，将 /media路径添加进去并点击Apply&Restart

2. Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed:

Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error running hook #0: error running hook: exit status 1, stdout: , stderr: Auto-detected mode as ‘legacy’
nvidia-container-cli: initialization error: load library failed: libnvidia-ml.so.1: cannot open shared object file: no such file or directory: unknown

3. Cannot connect to the Docker daemon at unix:///home/purples/.docker/desktop/docker.sock. Is the docker daemon running?

Cannot connect to the Docker daemon at unix:///home/purples/.docker/desktop/docker.sock. Is the docker daemon running?

解决方法：
一般重启docker即可：

systemctl restart docker

若还有问题，可能是因为下载了docker desktop，在个人目录留下了文件夹.docker，因此执行docker命令的时候默认去这里链接了。
则：

cd ~rm -rf .docker/

然后应该不会报错了

Get https://registry-1.docker.io/v2/: net/http: request canceled (Client.Timeout exceeded while awaiting headers)

这是因为网络问题导致的报错，
解决方法：换源
修改/etc/docker/daemon.json文件，该文件用于配置项目参数，默认不存在，需自己创建：

vi /etc/docker/daemon.json

导入镜像仓库：
Docker 官方中国区：https://registry.docker-cn.com
网易：http://hub-mirror.c.163.com
中国科技大学：https://docker.mirrors.ustc.edu.cn
阿里云：https://pee6w651.mirror.aliyuncs.com
选择一个镜像即可：

{"registry-mirrors":["https://pee6w651.mirror.aliyuncs.com"]}

添加后保存并关闭。
