根因分析

Docker 存储 overlay2 层的文件系统（通常为 /var/lib/docker）磁盘空间已满。

English

The filesystem where Docker stores overlay2 layers (usually /var/lib/docker) has run out of disk space.

解决方案

  1. Free up space: run 'docker system prune -a --volumes' to remove all unused images, containers, and volumes. Then check disk usage with 'df -h /var/lib/docker'.
  2. Increase disk space by adding a new storage device and moving Docker's data directory: edit /etc/docker/daemon.json with 'data-root': '/new/path', then restart Docker.

无效尝试

常见但无效的做法:

  1. 70% 失败

    Running 'docker system prune' only removes unused containers and images, but may not free enough space if the volume is too small.

  2. 95% 失败

    Restarting the Docker daemon does not free disk space; it only clears temporary locks.
