docker进入容器时报错 Error response from daemon: Container xxx is restarting, wait until the container is

使用docker run命令运行容器，再进入容器时报错

运行容器命令

docker run --restart=always --name mongo -v /data/mongo:/data/db -p 27017:27017 -d mongo --auth

进入容器命令

docker exec -it mongo bash

错误信息

Error response from daemon: Container 90831dd80b32a1502d9535c874ceec899b5fd70c883481195b4f36cd29be47b0 is restarting, wait until the container is running

[root@Tracy ~]# docker exec -it mongo bash
Error response from daemon: Container 90831dd80b32a1502d9535c874ceec899b5fd70c883481195b4f36cd29be47b0 is restarting, wait until the container is running

分析 

（1）查看容器是否启动

[root@Tracy ~]# docker ps
CONTAINER ID   IMAGE       COMMAND                  CREATED              STATUS                           PORTS                                                  NAMES
90831dd80b32   mongo       "docker-entrypoint.s…"   About a minute ago   Restarting (14) 20 seconds ago                                                          mongo

启动中，但是没有端囗

（2）查看端囗是否被占用

[root@Tracy ~]# lsof -i:27017

端囗没有被占用 

（3）查看docker日志

docker logs --tail 50 --follow --timestamps mongo  # mongo为容器名称

其中有个错误信息提示：磁盘没有空间了

（4）查看磁盘空间

du -ach / --max-depth=1

磁盘空间一共20G，都被占满了，清除或扩容磁盘空间即可。
