У меня есть три docker-контейнера, один работает под управлением php5 + apache с установленным Drupal, а другой - под лаком 4.1, а последний - под MySQL.Вот мой docker-compose.yml 

version: "2"
services:
  app:
    container_name: drupal.app
    build: .build/php5-apache
    working_dir: "/var/www/html/"
    ports:
      - "8080:80"
    volumes:
      - ".:/var/www/html/"
    restart: always
    networks:
      vpcbr:
        ipv4_address: 10.5.0.5
    links:
      - db
  db:
    container_name: drupal.db
    #image: mysql:5.5
    build: .build/mysql
    ports:
      - "3306:3306"
    environment:
      MYSQL_ROOT_PASSWORD: dskjfskjhfnksdnf
    volumes:
      - ./data/mysql:/var/lib/mysql
    networks:
      vpcbr:
        ipv4_address: 10.5.0.4
    restart: always
  varnish:
    container_name: drupal.varnish
    build: .build/varnish
    ports:
      - "80:80"
    networks:
      vpcbr:
        ipv4_address: 10.5.0.3
    restart: always
    tty: true
networks:
  vpcbr:
    driver: bridge
    ipam:
     config:
       - subnet: 10.5.0.0/16
         gateway: 10.5.0.1

А вот default.vcl для лака 

#
# This is an example VCL file for Varnish.
#
# It does not do anything by default, delegating control to the
# builtin VCL. The builtin VCL is called when there is no explicit
# return statement.
#
# See the VCL chapters in the Users Guide at https://www.varnish-cache.org/docs/
# and https://www.varnish-cache.org/trac/wiki/VCLExamples for more examples.

# Marker to tell the VCL compiler that this VCL has been adapted to the
# new 4.0 format.
vcl 4.0;

# Default backend definition. Set this to point to your content server.
backend default {
    .host = "10.5.0.5";
    .port = "80";
}

sub vcl_recv {
    # Happens before we check if we have this in cache already.
    #
    # Typically you clean up the request here, removing cookies you don't need,
    # rewriting the request, etc.

  set req.backend_hint = bar.backend();

  # Do not cache these paths.

  # and keep them equal.

    unset req.http.Cookie;
  }

  # Remove all cookies that Drupal doesn't need to know about. We explicitly
  # list the ones that Drupal does need, the SESS and NO_CACHE. If, after
  # running this code we find that either of these two cookies remains, we
  # will pass as the page cannot be cached.
  if (req.http.Cookie) {
    # 1. Append a semi-colon to the front of the cookie string.
    # 2. Remove all spaces that appear after semi-colons.
    # 3. Match the cookies we want to keep, adding the space we removed
    #    previously back. (\1) is first matching group in the regsuball.
    # 4. Remove all other cookies, identifying them by the fact that they have
    #    no space after the preceding semi-colon.
    # 5. Remove all spaces and semi-colons from the beginning and end of the
    #    cookie string.
    set req.http.Cookie = ";" + req.http.Cookie;
    set req.http.Cookie = regsuball(req.http.Cookie, "; +", ";");
    set req.http.Cookie = regsuball(req.http.Cookie, ";(SESS[a-z0-9]+|SSESS[a-z0-9]+|NO_CACHE)=", "; \1=");

    if (req.http.Cookie == "") {
      # If there are no remaining cookies, remove the cookie header. If there
      # aren't any cookie headers, Varnish's default behavior will be to cache
      # the page.
      unset req.http.Cookie;
    }
    else {
      # If there is any cookies left (a session or NO_CACHE cookie), do not
      # cache the page. Pass it on to Apache directly.
      return (pass);
    }
  }
}

sub vcl_backend_response {
    # Happens after we have read the response headers from the backend.
    #
    # Here you clean the response headers, removing silly Set-Cookie headers
    # and other mistakes your backend does.
}

sub vcl_deliver {
    # Happens when we have all the pieces we need, and are about to send the
    # response to the client.
    #
    # You can do accounting or modifying the final object here.
}

Я использовал curl, чтобы проверить, может ли сервер лака соединиться с сервером drupalчерез ip 10.5.0.5 и результат положительный.

Однако всякий раз, когда я пытаюсь получить доступ к Интернету через http://localhost/, лак всегда выдает ошибку 503 и не может получить Backend.

Может кто-нибудь сказать мне, что-то не так с моей настройкой default.vcl или настройкой docker-compose.

Где вы пытались получить доступ к URL http://localhost с?

Из того, что я знаю, кэш Varnish должен быть размещен в другом экземпляре, а не в том же экземпляре, в котором вы пытаетесь кэшировать содержимое.Таким образом, вы должны указать URL к кешу Varnish, который не должен быть 10.5.0.5.

Ваши настройки Vanish VCL, похоже, верны, что слушает кеширование контента из 10.5.0.5 в порту 80 хотя.

Я не уверен, что мост работает таким образом, вы пытались использовать только "имя" varnish в vcl по умолчанию вместо ip-адреса?
