Docker問題日誌--工做中遇到的問題及解決

1. 啓動Docker容器時遇到錯誤

• 標籤:

docker, docker run, docker start,

• 環境:

Docker version 1.12.6, build 1398f24/1.12.6

[root@localhost jenkins]# cat /proc/version

Linux version 3.10.0-514.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-11) (GCC) ) #1 SMP Tue Nov 22 16:42:41 UTC 2016

[root@localhost jenkins]# cat /etc/redhat-release

CentOS Linux release 7.3.1611 (Core)

[root@localhost jenkins]#

我在Share PC上運行Docker, Share PC不能上外網

 

• 問題描述:

[root@localhost ~]# docker run centos /bin/echo 'Hello World'

container_linux.go:247: starting container process caused "process_linux.go:334: running prestart hook 1 caused \"error running hook: exit status 1, stdout: , stderr: \""

/usr/bin/docker-current: Error response from daemon: invalid header field value "oci runtime error: container_linux.go:247: starting container process caused \"process_linux.go:334: running prestart hook 1 caused \\\"error running hook: exit status 1, stdout: , stderr: \\\"\"\n".

• 問題分析:

該問題是因爲設置了Docker代理引發的.

設置Docker代理以下:

# following link is to resolve docker-runc not found issue,proxy is not necessary *#

ln -s /usr/libexec/docker/docker-proxy-current /usr/bin/docker-proxy

ln -s /usr/libexec/docker/docker-runc-current /usr/bin/docker-runc

# 設置代理

sudo HTTP_PROXY=http://135.251.33.16:80 /usr/bin/dockerd --userland-proxy=false &

• 解決方案:

我嘗試了Disable SELinux

修改配置文件須要重啓機器：

修改/etc/selinux/config 文件

將SELINUX=enforcing改成SELINUX=disabled

不成功.

而後我試圖中止由代理啓動(sudo HTTP_PROXY命令)的docker服務: service docker stop

顯示中止成功,可是實際沒有成功.

最後我重啓Share PC.

重啓後,啓動Docker: service docker start.

就能夠正確運行docker了:

[root@localhost ~]# docker run centos /bin/echo 'Hello World'

Hello World

[root@localhost ~]#

其餘:

我如今擔憂是否是在建立Dockerfile並build時,是否須要
