問題描述

服務器上的registry已經啟動了

看了下文檔要使用Insecure Registry要添加DOCKER_OPTS='--insecure-registry myregistrydomain.com:5000'但沒有找到/etc/sysconfig/docker這文件，所以就在docker.service里添加了如下（centos7好像沒/etc/sysconfig/docker這文件了）

ExecStart=/usr/bin/docker daemon --registry-mirror=https://187wuopo.mirror.aliyuncs.com --insecure-registry 121.42.217.35:5000 -H fd://

sudo docker push 121.42.217.35:5000/php:7

報錯：Get https://121.42.217.35:5000/v1/_ping: tls: oversized record received with length 20527

感覺是DOCKER_OPTS放錯地方了...

問題解答

可能是/etc/default/docker這個地址？修改/添加DOCKER_OPTS如下：

DOCKER_OPTS='--insecure-registry 121.42.217.35:5000'回答2：
