關於docker 意外中止，從新快速啓動措施

1. 咱們要重啓這個鏡像，須要知道這個鏡像ID，相似這個：

7079ff99e10ac326726a364348853c0e508cad8ce00ae970f3c800f172a40252

那麼你能夠跳過下面的這個步驟:

　　1. 咱們先找到docker 的存放位置，默認的docker 鏡像防止在/var/lib/docekr 位置,可是通常來講var的目錄比較小，若是咱們存的image鏡像比較大的話，可能須要修改默認存儲地址，這個在這裏不講.  咱們採用 sudo docker info 來查詢

sudo docker info

咱們沒有發現

Docker Root Dir: 

這個字段，因此說明目錄存儲在/var/lib/docker 目錄下，因此咱們直接在這個目錄下去尋找就能夠了.

咱們這裏是由於修改了docker的默認的存儲路徑:

[root@localhost ~]# sudo docker info

因此這裏去/data1/docker下面尋找：

[root@localhost ~]# ls /data1/docker/containers

7079ff99e10ac326726a364348853c0e508cad8ce00ae970f3c800f172a40252

[root@localhost ~]# 

而後咱們使用這個重啓：

首先，查看咱們的容器信息：

sudo docker inspect  7079ff99e10ac326726a364348853c0e508cad8ce00ae970f3c800f172a40252

啓動你的容器

sudo docker start 7079ff99e10ac326726a364348853c0e508cad8ce00ae970f3c800f172a40252

 

而後使用sudo docker ps  查看容器狀態：

[root@localhost ~]# docker ps
CONTAINER ID        IMAGE                                  COMMAND                  CREATED             STATUS              PORTS               NAMES
7079ff99e10a        xxxxxxx.xxx.xxx   "/usr/sbin/entrypo..."   2 weeks ago         Up 28 minutes                           elated_ramanujan

 

 

這樣咱們的容器就恢復了. 而後咱們進入容器，去重啓應用服務吧.

[root@localhost ~]# sudo docker exec  -it  7079ff99e10a  bash

而後就去恢復應用吧.
