上一章已經建立好了私有的 Registry 這一章則要來實作建立 image 然後推送

1. 建立一個 image

#docker build -t web:1.0 .

參數說明:
buile : 利用 Dockerfile 建立一個 image
-t : 針對這個 image 命名，前面是名字後面是 Tag
. : Dockerfile 的位置

2. 標記已建立的 image

#docker tag web:1.0 127.0.0.1:5000/test:1.0

#docker images

REPOSITORY            TAG       IMAGE ID       CREATED        SIZE
127.0.0.1:5000/test   1.0       c805ef25f0f3   20 hours ago   489MB
web                   1.0       c805ef25f0f3   20 hours ago   489MB

完成標記後就會多出一個image的連結

3. 上傳已標記的 image

#docker push 127.0.0.1:5000/test:1.0

The push refers to repository [127.0.0.1:5000/test]
1d5d2e5962a7: Pushed
703a038a27f4: Pushed
e4f1b55f3f8a: Pushed

c29cc6c693ff: Pushed

4. 確認已上傳的 image
http://127.0.0.1:5000/v2/_catalog
使用網址可以確認以上傳的 image

{
repositories: [
"test"
]
}

如果要拉下來就帶上位置就好了

#docker pull 127.0.0.1:5000/test:1.0
