上傳image到dockerhub

1. 在dockerhub上註冊, https://www.docker.com/products/docker-hub
2. sudo docker images 確認

(base) lmx@lmx-up:~$ sudo docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
faster-rcnn-3d      v1                  1417b43a3ff5        10 months ago       9.13GB
hello-world         latest              fce289e99eb9        10 months ago       1.84kB

---

非常注意：
上傳到dockerhub需要改名字。image名字改成 usr/dockername形式。
參考我的：dockerlimx/faster-rcnn-3d，dockerlimx是我dockerhub用戶名，後面是我的image名字。

---

我要傳的是第一個。所以需要先改名，改名方法參考我的博文。

改名完後，如下：

(base) lmx@lmx-up:~$ sudo docker images
REPOSITORY                  TAG                 IMAGE ID            CREATED             SIZE
dockerlimx/faster-rcnn-3d   v1                  1417b43a3ff5        10 months ago       9.13GB

3. sudo docker login 登錄
4. sudo docker push dockerlimx/faster-rcnn-3d
5. 等待

(base) lmx@lmx-up:~$ sudo docker push dockerlimx/faster-rcnn-3d
The push refers to repository [docker.io/dockerlimx/faster-rcnn-3d]
