在azure应用程序服务中托管简单的nginx / html容器时出现问题

Question

我正在尝试使用 nginx - azure 应用程序服务 w/ docker-compose 设置一个简单的 nginx 端点。我可以在本地运行 docker-compose，这工作得很好，但在 azure 应用程序服务中我遇到了基本的应用程序错误。

Docker-Compose Azure App Configuration
version: '2.2'
services:
  loadbalancer:
    image: .../loadbalancertest
    networks:
      - mynetwork
    ports:
      - 80:8090
    tty: true
networks:
  mynetwork:
    driver: bridge

Dockerfile
FROM nginx:alpine
RUN apk update && apk upgrade && apk add bash curl && apk add openssl;
RUN rm /etc/nginx/conf.d/default.conf
COPY nginx.conf /etc/nginx/conf.d/default.conf
COPY index.html /usr/share/nginx/html
RUN mkdir /usr/nginx
RUN openssl req -x509 -nodes -days 3650 -subj "/C=CA/ST=QC/O=Company, Inc./CN=isiGov.gov" -addext "subjectAltName=DNS:isiGov.gov" -newkey rsa:2048 -keyout /usr/nginx/ssl.key -out /usr/nginx/ssl.crt;
EXPOSE 8090

# Start Nginx
CMD ["nginx", "-g", "daemon off;"]

index.html
<!DOCTYPE html>
<html>
<head>
    <title>Hello World</title>
</head>
<body>
    <h1>Hello World</h1>
    <p>Welcome to your first HTML document!</p>
</body>
</html>

error_log  ./error.log warn;

server {
    server_name _;
    listen 8090 ssl;
    underscores_in_headers on;
    ssl_certificate /usr/nginx/ssl.crt;

    }
}

当我尝试访问网站网址时，出现应用程序错误。当我检查日志时，我看到 azure 说它在启动过程中失败。

当我尝试你的代码时，我遇到了同样的错误。

发生错误的原因是 Azure 应用服务期望应用程序在端口 80 上运行，但您的
```
docker-compose.yml
```
将容器端口 8090 映射到主机端口 80。

我在

docker-compose.yml

文件

中将端口更改为80

ports:
- "80:80"

因此，请更新您的
```
nginx.conf
```
以侦听端口 80 而不是 8090。

nginx.conf：

server  {
listen  80;
server_name localhost;
location / {
root /usr/share/nginx/html;
index  index.html index.htm;
}

还更新您的

docker file

以侦听端口 80。

Dockerfile：

EXPOSE  80

通过执行上述更改，我已通过 Azure 容器注册表成功将应用程序部署到 Azure 应用服务。

我运行了以下命令来构建应用程序。

 docker build -t <image-name> .

运行以下命令将 docker 映像推送到 Azure 容器注册表。

az acr login -n <container-registry>
docker tag <image-name> <container-registry>.azurecr.io/<image-name>:<tag>
docker push <container-registry>.azurecr.io/<image-name>:<tag>

部署后输出：
