Google Container Registry(GCR)是GCP提供以Google Cloud Storage為儲存空間的Docker Registry，可以透過GCP的Cloud Storage空間來存放Image。

事前準備

1. 啟用Google Container Registry API
2. 安裝gclound和docker
3. 設定權限/授權

gcloud auth configure-docker

將上傳映像檔到GCR

• 建立Docke Image

docker build -t [HOSTNAME]/[PROJECT-ID]/[IMAGE] -f [DOCKERFILE_PATH] .

HOSTNAME: 映像檔的存儲位置
- gcr.io 美國
- us.gcr.io 美國
- eu.gcr.io 歐洲
- asia.gcr.io 亞洲

• 將已經建好的映像檔更改註冊名稱

docker tag [SOURCE_IMAGE]:[TAG] [HOSTNAME]/[PROJECT-ID]/[IMAGE]:[TAG]

➜  ~ docker tag myproject:v1.0.1 gcr.io/xxxxx/myproject:v1.0.1
➜  ~ docker image ls
REPOSITORY                     TAG                 IMAGE ID            CREATED             SIZE
myproject                     v1.0.1              dc3608e3892f        7 days ago          364MB
gcr.io/xxxxxx/myproject      v1.0.1              dc3608e3892f        7 days ago          364MB

• 將映像檔推送到Container Registry

docker push [HOSTNAME]/[PROJECT-ID]/[IMAGE]:[TAG]

上傳映像檔成功後如下

➜  ~ docker push gcr.io/xxxxxx/myproject:v1.0.1
The push refers to repository [gcr.io/xxx-xxx/myproject]
