asp.net - Nginx 无法将 Docker 部署到 Amazon

Question

我正在尝试通过 elasticbeanstalk 将 Docker 容器中的 .net asp web api 应用程序部署到 Amazon，但这是我得到的:

ERROR: Failed to start nginx, abort deployment
ERROR: [Instance: i-ecf0d365] Command failed on instance. Return code: 1 Output: nginx: [emerg] invalid host in upstream "172.17.0.2:5000/tcp" in /etc/nginx/conf.d/elasticbeanstalk-nginx-docker-upstream.conf:2
nginx: configuration file /etc/nginx/nginx.conf test failed

文件

FROM microsoft/aspnet:latest

COPY . /app
WORKDIR /app
RUN ["dnu", "restore"]

EXPOSE 5000/tcp
ENTRYPOINT ["dnx", "-p", "project.json", "web"]

elasticbeanstalk-nginx-docker-upstream.conf 文件

upstream docker {
    server 172.17.0.2:5000/tcp;
    keepalive 256;
}

Answer 1

错误消息 nginx: [emerg] invalid host in upstream "172.17.0.2:5000/tcp" 显示了一个 upstream server 参数，在端口号后面带有伪字符 /tcp。见 upstream module documentation 。

@Fishman 确认 nginx 配置文件中出现了错误的参数，并且该文件是从 Dockerfile 生成的，并且通过将 EXPOSE 参数(在 Dockerfile 内)的值从 5000/tcp 更改为 5000 来纠正问题。
