【Docker】本地镜像发布到阿里云

发布流程

推送步骤

做好本地镜像

[root@192 ~]# docker images
REPOSITORY    TAG       IMAGE ID       CREATED         SIZE
kd/myubuntu   1.1       dac744a2b764   4 seconds ago   183MB
ubuntu        latest    ba6acccedd29   17 months ago   72.8MB
redis         6.0.8     16ecd2772934   2 years ago     104MB

这里就使用之前创建的kd/myubuntu。

进入阿里云开发者平台。
