storage 运行了,但是docker container ls 不显示

本文介绍了一种常见情况,即Storage服务已成功运行,但在使用dockercontainerls命令时却无法显示相应的Docker容器。文章提供了具体的解决步骤,包括在/var/fdfs/storage/data目录下删除fdfs_storaged_pid文件,然后重新启动Storage服务。

storage 运行了,但是docker container ls 不显示

运行storage 的时候,如果,storsge 不可以打开,需要在/var/fdfs/storage/data 将fdfs_storaged_pid 删除,
然后重新启动

在这里插入图片描述

### Docker Root Configuration and Permissions Docker requires elevated privileges for many operations due to its interaction with system resources such as network interfaces, storage devices, and namespaces. Running Docker necessitates root permissions because it involves managing these critical components of the operating system[^3]. #### Default Root Directory Path By default, Docker stores container data under `/var/lib/docker`. This directory is owned by `root` and contains all images, containers, volumes, and other runtime files associated with Docker. ```bash ls -ld /var/lib/docker ``` This command will show that the ownership belongs to `root`. #### Configuring Non-root Users For security reasons, allowing non-root users to interact safely with Docker without compromising system integrity is important. To achieve this: - **Group Management**: Add specific users to the `docker` group which allows them to execute Docker commands without needing `sudo`. ```bash sudo usermod -aG docker ${USER} ``` After adding a user to the `docker` group, logging out and back in again may be required so changes take effect properly. #### Changing Data Storage Location If changing where Docker keeps its data (not recommended unless necessary), modify the daemon.json file located at `/etc/docker/daemon.json`, specifying an alternative path using `"data-root"` key-value pair. ```json { "data-root": "/mnt/newlocation" } ``` Restarting the Docker service after making modifications ensures they are applied correctly. #### Security Implications Granting full access to Docker can pose significant risks since any process running inside a container could potentially exploit vulnerabilities leading to privilege escalation on host systems. Therefore, always follow best practices when configuring Docker environments including limiting capabilities granted within containers whenever possible.
