升級docker到1.12後,發現使用原來的/etc/sysconfig/docker文件中設置--insecure-registry的方式,訪問registry失敗,提示「http: server gave HTTP response to HTTPS client」。docker
[root@localhost ~]# docker login registry:5000 Username : Password: Error response from daemon: Get https://registry:5000/v1/users/: http: server gave HTTP response to HTTPS client
多方搜索後,原來是docker修改了--insecure-registry的配置方式,改成使用json文件配置了。json
建立/etc/docker/daemon.json文件,內容爲{ "insecure-registries":["registry:5000"] }。spa
[root@localhost ~]# cat /etc/docker/daemon.json { "insecure-registries":["registry:5000"] }
而後,重啓docker服務便可訪問registry。code
