Cloud Run error: Container failed to start

Question

我无法获得部署到 Google 云运行的基本 Angular 应用程序。该错误表明它没有在端口 8080 上正确提供服务，但运行在我的机器上本地 localhost:8080 显示该应用程序。所以我可能需要一些额外的云运行，如果有人有想法？

详情如下：

我创建了一个基本的 angular 应用程序

ng new test-app

Dockerfile如下

FROM node:latest as node
WORKDIR /app
COPY . .

RUN npm install
RUN npm run build --prod

ENV PORT=8080

FROM nginx:latest
COPY --from=node /app/dist/test-app /usr/share/nginx/html
EXPOSE 8080
CMD ["nginx", "-g", "daemon off;"]

本地我运行构建的容器，我可以在 localhost:8080

看到它

docker container run -p 8080:80 gcr.io/$GOOGLE_PROJECT/test-app:$IMAGE

screenshot

然后我部署到 Google 云运行托管。

gcloud run deploy test-app --image gcr.io/$GOOGLE_PROJECT/test-app:$IMAGE --platform managed

但是启动失败，报错

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.

日志中没有其他错误。

谢谢。

我从

中获取的有效解决方案

我创建了 nginx.conf 文件，将端口设置为 8080，将服务器设置为 0.0.0.0

# on alpine, copy to /etc/nginx/nginx.conf
user                            root;
worker_processes                auto;

error_log                       /var/log/nginx/error.log warn;

events {
    worker_connections          1024;
}

http {
    include                     /etc/nginx/mime.types;
    default_type                application/octet-stream;
    sendfile                    off;
    access_log                  off;
    keepalive_timeout           3000;
    server {
        listen                  8080;
        root                    /usr/share/nginx/html;
        index                   index.html;
        server_name             0.0.0.0;
        client_max_body_size    16m;
    }
}

并更新了 Dockerfile 以复制此文件。

FROM node:latest as node
WORKDIR /app
COPY . .
RUN npm install
RUN npm run build --prod

ENV PORT=8080

FROM nginx:alpine
COPY --from=node /app/dist/streamin-app/ /usr/share/nginx/html/
COPY nginx.conf /etc/nginx/
EXPOSE 8080
CMD ["nginx", "-g", "daemon off;"]

Answer 1

我认为与监听所有网络接口的容器有关。

根据官方文档：

A common reason for Cloud Run services failing to start is that the server process inside the container is configured to listen on the localhost (127.0.0.1) address. This refers to the loopback network interface, which is not accessible from outside the container and therefore Cloud Run health check cannot be performed, causing the service deployment failure.

To solve this, configure your application to start the HTTP server to listen on all network interfaces, commonly denoted as 0.0.0.0.

Answer 2

“docker容器运行-p8080:80gcr.io/$GOOGLE_PROJECT/test-app:$IMAGE”

显示您已将本地计算机的端口 8080 映射到镜像的端口 80，这表明您的镜像正在侦听端口 80。

您可以 1) 更改图像或 2) 使用自定义端口部署到云运行：

gcloud alpha 运行部署...-端口 80

Answer 3

顺便说一句，我根本没有弄乱 nginx
我的 docker 文件中只有 EXPOSE 4200
我在此处的容器设置中添加了容器端口 4200：

然后它给了我一个 URL 置顶：

这给了我一个无效的主机 header 错误，我通过重新部署我的容器修复了这个错误：

CMD ng serve --host 0.0.0.0 --disable-host-check
