我將示範如何在cloud run上部署一個簡單的容器。
Cloud Run 是一個完全託管的平台,可讓您直接在 Google 可擴展的基礎架構之上運行程式碼。 Cloud Run 簡單、自動化,旨在提高您的工作效率。
我按照官方 fastapi 文件啟動了一個 hello world 應用程式
建立requirements.txt檔案
fastapi[standard] pydantic>=2.7.0,<3.0.0
from typing import Union from fastapi import FastAPI app = FastAPI() @app.get("/") def read_root(): return {"Hello": "World"} @app.get("/items/{item_id}") def read_item(item_id: int, q: Union[str, None] = None): return {"item_id": item_id, "q": q}
建立 Dockerfile
FROM python:3.9 WORKDIR /code COPY ./requirements.txt /code/requirements.txt RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt COPY ./app /code/app CMD ["fastapi", "run", "app/main.py", "--port", "80"]
GitHub 操作
為了讓 GitHub 操作流程能夠取得 YAML 文件,它需要有特定的儲存位置。每個使用操作的儲存庫都需要一個名為 /.github/workflows
*使用 GCP 更多資訊配置此工作流程 *
# This workflow build and push a Docker container to Google Artifact Registry # and deploy it on Cloud Run when a commit is pushed to the $default-branch # branch. # # To configure this workflow: # # 1. Enable the following Google Cloud APIs: # # - Artifact Registry (artifactregistry.googleapis.com) # - Cloud Run (run.googleapis.com) # - IAM Credentials API (iamcredentials.googleapis.com) # # You can learn more about enabling APIs at # https://support.google.com/googleapi/answer/6158841. # # 2. Create and configure a Workload Identity Provider for GitHub: # https://github.com/google-github-actions/auth#preferred-direct-workload-identity-federation. # # Depending on how you authenticate, you will need to grant an IAM principal # permissions on Google Cloud: # # - Artifact Registry Administrator (roles/artifactregistry.admin) # - Cloud Run Developer (roles/run.developer) # # You can learn more about setting IAM permissions at # https://cloud.google.com/iam/docs/manage-access-other-resources # # 3. Change the values in the "env" block to match your values.
建立檔案 google-cloudrun-docker.yml

目錄結構
您現在應該具有以下目錄結構:
├── app │ ├── __init__.py │ └── main.py ├── Dockerfile └── requirements.txt └── requirements.txt ├── .github │ ├── workflows ├── google-cloudrun-docker.yml
> 1. Create a new repo in gitHUb > 2. Push your exisisting code to new repository on default branch
