无法在 gcp cloud run 上托管 angular 7 应用程序

Question

我已经构建了一个 Angular 7 应用程序，当我ng serve使用 docker 从本地机器运行命令时，该应用程序可以正常工作。这是一个简单的 hello world angular 应用程序（没有数据库）。

当我尝试在 GCP Cloud Run 上托管我的应用程序时。它给了我端口错误。

云运行错误：

无法启动然后侦听由 PORT 环境变量定义的端口。

ERROR: (gcloud.beta.run.deploy) Cloud Run error: Container failed to start. Failed to start and then listen on the port defined by the PORT environment variable. Logs for this revision might contain more information.

Deploying container to Cloud Run service [test-case-builder] in project [test-case-builder] region [us-central1]
Already have image (with digest): gcr.io/cloud-builders/gcloud

这是我的 docker 文件

    FROM node:latest as node
    # set working directory
    WORKDIR /app
    COPY . .
    RUN npm install
    RUN npm run build --prod
    FROM nginx:alpine
    COPY --from=node /app/dist/test-case-builder usr/share/nginx/html
    CMD ng serve --host 0.0.0.0

您需要监听PORTenv var 中定义的端口。所以在你Dockerfile做的：

CMD ng serve --host 0.0.0.0 --port $PORT
