已经启动成功

在我本地mac机器上拉去一个echoserver，为推送到本地仓库做准备。Mac上之前已经装了docker，如果你想学习如何安装docker，参考这里吧https://docs.docker.com/get-started/#prerequisites

开始我是从默认的docker hub上下载，非常的慢，慢到无法忍受

bjjbgi-3-86:~ zhangxiaolong$ docker pull googlecontainer/echoserver:1.4Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: TLS handshake timeoutbjjbgi-3-86:~ zhangxiaolong$ docker pull googlecontainer/echoserver:1.41.4: Pulling from googlecontainer/echoserver31baf3c5ae52: Pull complete a3ed95caeb02: Pull complete 551b3b58cb23: Pull complete a38d08741281: Waiting c587ef22eeed: Download complete 3d17cbe426dd: Download complete 8cec8097f762: Download complete 326de4e8cdb3: Download complete ^C

找了个国内代理
registry.docker-cn.com/googlecontainer/echoserver:1.4

爽爽的下载下来了。

本地将其tag一个新名字

bjjbgi-3-86:~ zhangxiaolong$ sudo docker tag a90209bb39e3 10.20.2.127:5000/echoserver

jjbgi-3-86:~ zhangxiaolong$ docker imagesREPOSITORY                                          TAG                 IMAGE ID            CREATED             SIZEhello-world                                         latest              48b5124b2768        6 months ago        1.84 kB10.20.2.127:5000/echoserver                         latest              a90209bb39e3        14 months ago       140 MBregistry.docker-cn.com/googlecontainer/echoserver   1.4                 a90209bb39e3        14 months ago       140 MB

准备push到私服上去

bjjbgi-3-86:~ zhangxiaolong$ sudo docker push 10.20.2.127:5000/echoserver

报了一个错

bjjbgi-3-86:~ zhangxiaolong$ sudo docker push 10.20.2.127:5000/echoserverThe push refers to a repository [10.20.2.127:5000/echoserver]Get https://10.20.2.127:5000/v1/_ping: http: server gave HTTP response to HTTPS client

大概就是我仓库那台机器没有配置https的原因。

解决方案：增加insecure-registries参数配置
Linux的修改方法是
在”/etc/docker/“目录下，创建”daemon.json“文件。在文件中写入：

{ “insecure-registries”:[“192.168.1.100:5000”] }

保存退出后，重启docker。问题解决：

或者
通过修改docker的配置文件“etc/systemconfig/docker”，重启docker来解决这个问题，发现docker1.12.3版本没有此文件

mac的解决方案是

然后再push

成功。
