上傳你的映像檔docker push

把前面做好的自己的 Docker Image Push到公開網路的 Docker Hub 上，所有的人都可以把這個 Docker Image Pull 下來使用。

實作的流程如下：

1. 註冊 Docker Hub 帳號

2. 把 Docker Image Push 到 Docker Hub 上

3. 測試是否成功的把 Docker Image Push 到 Docker Hub 上

一. 註冊 Docker Hub 帳號

到 Docker Hub 的網站如下圖，註冊一個身份

把 Docker Image Push 到 Docker Hub 上，需要把 Docker Image 加上 tag，如下

docker tag kawsing/xoops kawsing/xoops
docker images kawsing/xoops
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
kawsing/xoops       latest              f04859f57535        7 minutes ago       384MB
