今天在docker搭建redis環(huán)境的時(shí)候，發(fā)現(xiàn)yum拉取不到資源，上不到網(wǎng)，報(bào)了如下錯(cuò)誤：

測(cè)試wget

wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

結(jié)果報(bào)錯(cuò)

unknown host mirrors.163.com

測(cè)試ping

在容器內(nèi)部

ping www.baidu.com

結(jié)果還是失敗

ping: unknown host www.baidu.com

多開一個(gè)終端，進(jìn)入主機(jī)（不是進(jìn)入容器），進(jìn)行ping命令測(cè)試發(fā)現(xiàn)是OK的，基本可以確定是docker的問(wèn)題了，而不是網(wǎng)絡(luò)問(wèn)題

解決方法

停止所有容器，重啟docker

service docker restart

內(nèi)容擴(kuò)展

Docker容器內(nèi)不能聯(lián)網(wǎng)的6種解決方案

1.使用–net:host選項(xiàng)

2.使用–dns選項(xiàng)

3.改dns server

4.不用dnsmasq

5.重建docker0網(wǎng)絡(luò)

6.直接在docker內(nèi)修改/etc/hosts

以上就是解決docker容器無(wú)法ping外網(wǎng)的問(wèn)題的詳細(xì)內(nèi)容，更多關(guān)于docker容器無(wú)法ping外網(wǎng)的資料請(qǐng)關(guān)注本站其它相關(guān)文章！
