我有一个主服务器，主要用于自托管的应用程序（notes，git server，Jenkins server，等等），我想组织这个主服务器，这样我就不必记住每个容器的所有端口。

• http://home.server/
• http://home.server/jenkins
• http://home.server/cowyo
• http://home.server/pihole
• 等等。

我希望根端点路由到一个运行google的cadvisor的容器，以监视我所有容器的状态，/jenkins路由到Jenkins，/pihole路由到pi-hole，等等。
下面是我如何根据我对配置模式的理解来设置我的docker-compose和nginx.conf文件：
docker-compose.yml:

version: '3'
services:
    webserver:
        image: nginx:alpine
        container_name: webserver
        restart: unless-stopped
        tty: true
        ports:
            - "80:80"
            - "443:443"
        volumes:
            - ./:/var/www
            - ./nginx/conf.d/:/etc/nginx/conf.d/
        restart: unless-stopped

    cadvisor:
        image: 'google/cadvisor'
        volumes:
            - /:/rootfs:ro
            - /var/run:/var/run:ro
            - /sys:/sys:ro
            - /var/lib/docker/:/var/lib/docker:ro
            - /dev/disk/:/dev/disk:ro
        ports:
            - "8090:8090"

    pi-hole:
        container_name: pihole
        image: pihole/pihole:latest
        ports:
            - "53:53/tcp"
            - "53:53/udp"
            - "67:67/udp"
            - "8070:8070/tcp"
            - "4437:4437/tcp"
        environment:
            TZ: 'America/Chicago'
            # WEBPASSWORD: 'set a secure password here or it will be random'
        # Volumes store your data between container upgrades
        volumes:
            - './etc-pihole/:/etc/pihole/'
            - './etc-dnsmasq.d/:/etc/dnsmasq.d/'
        dns:
          - 127.0.0.1
          - 1.1.1.1
        # Recommended but not required (DHCP needs NET_ADMIN)
        #   https://github.com/pi-hole/docker-pi-hole#note-on-capabilities
        cap_add:
            - NET_ADMIN
        restart: unless-stopped

    cowyo:
        image: 'schollz/cowyo'
        ports:
            - "8050:8050"
        volumes:
            - './cowyo/data/:/data/'
        restart: unless-stopped

    jenkins:
        image: 'bitnami/jenkins:2'
        ports:
            - '8080:8080'
            - '8443:8443'
            - '50000:50000'

你知道我做错了什么吗？任何帮助都将不胜感激。
编辑：它现在运行方式的问题是，当我去上面的一个网址，我得到一个“这个网站不能到达”的错误。
Edit 2：上面的问题是由一个坏的nginx.conf文件引起的，该文件导致Docker容器无法正常启动。解决该问题后，我得到一个“502坏网关”。
