GCP Container Registry

1. 確認帳號已經啟用付費功能

2. 開啟API服務

3. 安裝 Cloud SDK

3.1 下載 SDK

1
2
3
mkdir gcloud
cd gcloud
wget https://dl.google.com/dl/cloudsdk/channels/rapid/downloads/google-cloud-sdk-218.0.0-linux-x86_64.tar.gz

3.2 解壓縮

1
2
gunzip google-cloud-sdk-218.0.0-linux-x86_64.tar.gz
tar xvf google-cloud-sdk-218.0.0-linux-x86_64.tar

這時候就可以看到 google-cloud-sdk/ 這個資料夾

3.3 執行指令

1
2
cd google-cloud-sdk/
./install.sh

3.4 init SDK

1
2
cd bin
./gcloud init

把網址貼到網頁上面 取得 verification code

4. Build image

4.1.1 建立 Dockerfile

1
2
3
mkdir gcpimagetest
cd gcpimagetest/
vi Dockerfile

4.1.2 將官方的範例貼上去

# The Dockerfile defines the image's environment
# Import Python runtime and set up working directory
FROM python:2.7-alpine
WORKDIR /app
ADD . /app

# Install any necessary dependencies
RUN pip install -r ./requirements.txt

# Open port 80 for serving the webpage
EXPOSE 80

# Run app.py when the container launches
CMD ["python", "app.py"]

4.1.3 建立 requirements.txt

# This file defines the image's dependencies
Flask

4.1.4 建立 app.py

# The Docker image contains the following code
from flask import Flask
import os
import socket

app = Flask(__name__)

@app.route("/")
def hello():
    html = "<h3>Hello, World!</h3>"
    return html

if __name__ == "__main__":
  app.run(host='0.0.0.0', port=80)

4.2 建立 image

1
docker build -t quickstart-image .

gcloud auth 設定(只要設定一次就可以了)

1
./gcloud auth configure-docker

4.3 tag image

1
docker tag quickstart-image gcr.io/[PROJECT-ID]/quickstart-image:tag1

5. Push Image

5.1 push 前要安裝憑證

5.2 建立 docker-credential-gcr

1
vi docker-credential-gcr

5.3 輸入以下憑證

7
VERSION=1.5.0
OS=linux  # or "darwin" for OSX, "windows" for Windows.
ARCH=amd64  # or "386" for 32-bit OSs

curl -fsSL "https://github.com/GoogleCloudPlatform/docker-credential-gcr/releases/download/v${VERSION}/docker-credential-gcr_${OS}_${ARCH}-${VERSION}.tar.gz" \
  | tar xz --to-stdout ./docker-credential-gcr \
  > /usr/bin/docker-credential-gcr && chmod +x /usr/bin/docker-credential-gcr

5.4 設定憑證

記得要回到目錄的最上層才可以設定

1
./gcloud/google-cloud-sdk/bin/gcloud  components install docker-credential-gcr

成功畫面

5.5 提升 docker-credential-gcr 文件權限 並執行 docker-credential-gcr設定

1
2
chmod 777 docker-credential-gcr
docker-credential-gcr configure-docker

5.6 設定完成之後就可以 推送到 gcp 上面了

1
docker push gcr.io/[PROJECT-ID]/quickstart-imag:tag1

6. Pull Image

1
docker pull gcr.io/[PROJECT-ID]/quickstart-image:tag1
