云运行错误：容器无法启动 [英] Cloud Run error: Container failed to start

问题描述

我无法将基本的Angular应用部署到Google Cloud Run。该错误表明该端口8080不能正确提供服务，但是在我的计算机localhost：8080上本地运行会显示该应用程序。因此，如果有人有想法，我可能需要一些额外的资源来运行云？

I am failing to get a basic Angular app deploying to Google Cloud Run. The error would suggest it is not being served correctly at port 8080, but running locally on my machine localhost:8080 displays the app. So possibly I need something extra for cloud run, if anybody has some idea?

详细信息如下：

我创建了一个基本的角度应用程序

I create a basic angular app

ng new test-app

Dockerfile如下

The Dockerfile is as follows

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;"]

在本地运行构建的容器，可以在localhost：8080看到它

Locally I run the built container and I can see it at localhost:8080

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

屏幕截图

然后我将其部署到托管的Google Cloud Run。

I then deploy to Google Cloud Run managed.

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

但是，它无法从错误开始

However, it fails to start with the error

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。

我从如何在与docker结合使用时更改nginx的端口

nginx.conf文件，将端口设置为8080&服务器到高山上的0.0.0.0

I created the nginx.conf file, setting the port to 8080 & server to 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以复制该文件。

And updated the Dockerfile to copy over this file.

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;"]

推荐答案

I think与所有网络接口上的容器侦听有关。

I think is related to container listening on all network interfaces.

根据官方文档：

Cloud Run服务的常见原因无法启动的原因是容器中的
服务器进程配置为侦听
本地主机（127.0.0.1）地址。这指的是环回网络
接口，该接口无法从容器外部访问，而
则无法执行Cloud Run运行状况检查，从而导致
服务部署失败。

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.

要解决此问题，请将您的应用程序配置为启动HTTP服务器，以便
在所有网络接口上进行侦听，通常表示为0.0.0.0。

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