八个Docker常见故障

报错一：error initializing graphdriver

Docker启动报错

系统是CentOS 7.2
系统内核及docker版本如下：

[root@docker ~]# uname -r 3.10.0-327.el7.x86_64 [root@docker ~]# [root@docker ~]# [root@docker ~]# [root@docker ~]# docker version Client: Version: 18.04.0-ce API version: 1.37 Go version: go1.9.4 Git commit: 3d479c0 Built: Tue Apr 10 18:21:36 2018 OS/Arch: linux/amd64 Experimental: false Orchestrator: swarmServer: Engine: Version: 18.04.0-ce API version: 1.37 (minimum version 1.12) Go version: go1.9.4 Git commit: 3d479c0 Built: Tue Apr 10 18:25:25 2018 OS/Arch: linux/amd64 Experimental: false

启动报错提示如下：

[root@docker ~]# systemctl start docker Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journ [root@docker ~]# [root@docker ~]# [root@docker ~]# [root@docker ~]# systemctl status docker ● docker.service - Docker Application Container Engine Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled) Active: failed (Result: start-limit) since 日 2018-04-22 20:52:39 CST; 5s ago Docs: https://docs.docker.com Process: 4810 ExecStart=/usr/bin/dockerd (code=exited, status=1/FAILURE) Main PID: 4810 (code=exited, status=1/FAILURE)4月 22 20:52:39 docker.cgy.com systemd[1]: Failed to start Docker Application Container Engine. 4月 22 20:52:39 docker.cgy.com systemd[1]: Unit docker.service entered failed state. 4月 22 20:52:39 docker.cgy.com systemd[1]: docker.service failed. 4月 22 20:52:39 docker.cgy.com systemd[1]: docker.service holdoff time over, scheduling restart. 4月 22 20:52:39 docker.cgy.com systemd[1]: start request repeated too quickly for docker.service 4月 22 20:52:39 docker.cgy.com systemd[1]: Failed to start Docker Application Container Engine. 4月 22 20:52:39 docker.cgy.com systemd[1]: Unit docker.service entered failed state. 4月 22 20:52:39 docker.cgy.com systemd[1]: docker.service failed.

从以上报错提示信息中也没看到错误的具体原因。然后我又用dockerd来直接启动，就在输出信息最下面看到一条错误提示，如下：

[root@docker ~]# dockerd INFO[2018-04-22T21:12:46.111704443+08:00] libcontainerd: started new docker-containerd process pid=5903 INFO[0000] starting containerd module=containerd revision=773c489c9c1b21a6d78b5c538cd395416ec50f88 version=v1.0.3。。。。。。省略一部分输出。。。。。。INFO[0000] loading plugin "io.containerd.grpc.v1.introspection"... module=containerd type=io.containerd.grpc.v1 INFO[0000] serving... address="/var/run/docker/containerd/docker-containerd-debug.sock" module="containerd/debug" INFO[0000] serving... address="/var/run/docker/containerd/docker-containerd.sock" module="containerd/grpc" INFO[0000] containerd successfully booted in 0.002763s module=containerd Error starting daemon: error initializing graphdriver: overlay: the backing xfs filesystem is formatted without d_type support, which leads to incorrect behavior. Reformat the filesystem with ftype=1 to en d_type support. Backing filesystems without d_type support are not supported.

根据最后的报错Error starting daemon:搜索到这篇博客，得到解决。
https://blog.csdn.net/liu9718214/article/details/79134900

具体解决办法是：

vim /etc/sysconfig/docker
加入如下：

OPTIONS="--selinux-enabled --log-driver=journald --signature-verification=false"

/etc/docker/daemon.json
加入如下内容：

{ "registry-mirrors": ["http://4a1df5ef.m.daocloud.io"], # 是用来pull容器加速用的，跟此次问题无关。 "storage-driver": "devicemapper" # 解决此次问题 }

然后重启docker，顺利解决：

[root@docker ~]# systemctl restart docker [root@docker ~]# [root@docker ~]# [root@docker ~]# ps aux | grep docker root 5922 1.7 1.6 528432 62568 ? Ssl 21:15 0:00 /usr/bin/dockerd root 5927 1.1 0.5 356984 22100 ? Ssl 21:15 0:00 docker-containerd --config /var/run/docker/containerd/containerd.toml root 6028 0.0 0.0 112664 964 pts/0 S+ 21:15 0:00 grep --color=auto docker

报错二：iptables failed

FirewallD

CentOS-7 中介绍了 firewalld，firewall的底层是使用iptables进行数据过滤，建立在iptables之上，这可能会与 Docker 产生冲突。

当 firewalld 启动或者重启的时候，将会从 iptables 中移除 DOCKER 的规则，从而影响了 Docker 的正常工作。

当你使用的是 Systemd 的时候， firewalld 会在 Docker 之前启动，但是如果你在 Docker 启动之后再启动或者重启 firewalld ，你就需要重启 Docker 进程了。

系统：

[root@controller ~]# cat /etc/redhat-release CentOS Linux release 7.0.1406 (Core)

报错提示如下：

[root@controller ~]# docker run -it -P docker.io/nginx /usr/bin/docker-current: Error response from daemon: driver failed programming external connectivity on endpoint gloomy_kirch (10289e7a87e65771da90cda531951b7339bee9cb5953474460451cd48013aff0): iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 32810 -j DNAT --to-destination 172.17.0.2:80 ! -i docker0: iptables: No chain/target/match by that name. (exit status 1).

这是由于在运行这次容器之前，成功启动过一次，在上次访问时，因为防火墙的问题导致不能正常访问Nginx，所以将iptables的filter表清空了，并且重启过iptables，然后再次运行时，就报了以上错误。

解决办法

重启防火墙

#CentOS 7下执行 [root@controller ~]# systemctl restart firewalld

再重启docker守护进程即可

[root@controller ~]# systemctl restart docker

再次在容器中运行一个nginx就不会报错了

[root@controller ~]# docker run -it --name nginx -p 80:80 -v /www:/wwwroot docker.io/nginx /bin/bash root@a8a92c8f7760:/#

报错三 : Unable to take ownership of thin-pool

docker daemon启动失败：Unable to take ownership of thin-pool

原因： /var/lib/docker/devicemapper/metadata/ 内metadata丢失

I feel like the kcs kinda misses telling users the actual problem. Nor does it really make it clear the solution.IF you are using device mapper (instead of loopback) /var/lib/docker contains metadata informing docker about the contents of the device mapper storage area. If you delete /var/lib/docker that metadata is lost. Docker is then able to detect that the thin pool has data but docker is unable to make use of that information. The only solution is to delete the thin pool and recreate it so that both the thin pool and the metadata in /var/lib/docker will be empty.
