# 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**](https://hub.docker.com/) **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
```

docker login

```
docker login

```

**使用 `docker push` 指令把 Docker Image Push 到 Docker Hub 裡，指令如下**

**docker push kawsing/xoops**

```
docker push kawsing/xoops

The push refers to repository [docker.io/kawsing/xoops]
