我的微服务状态是关闭，我登录到 docker 容器：
docker exec -it {container_id} /bin/bash
容器中的应用日志输出：

我应该怎么做才能解决问题？ 如何调整容器磁盘使用情况？谢谢！
如何调整容器磁盘使用情况？
实际上，这与容器磁盘使用情况无关，这与 docker 主机的磁盘使用情况有关。
如果使用主机上的docker info | grep Dir查看，您可能会看到如下所示的内容：
Docker Root Dir: /var/lib/docker
此文件夹是用于所有容器的覆盖文件系统 docker。
因此，overlay 40G 38G 0 100% /仅表示主机磁盘已满/var/lib/docker。你的40G分区是不够的，你可以做的是下一步：
选项 1：
如果您有其他大于40G的分区，请更改docker的存储位置，如下所示。
选项 2：
只需释放当前磁盘(40G(上的一些空间(删除未使用的大图片，文档，安装程序等(。此外，我想你可能有很多未使用的图像和容器，那么你可以使用docker system prune -a来清理它们。但要注意接下来：
警告！这将删除：
- 所有停止的容器 - 至少一个容器未使用的所有网络 - 所有没有至少一个容器
关联的
映像 - 所有构建缓存
