docker - apierror-visualeditor-docserver-http-error :( curl 错误:7)无法连接到服务器

Question

我建立容器:docker build -t mediawiki31 .
带有Wikimedia的Dockerfile(标准文件加上VisualEditor):

FROM php:7.2-apache

    } > /usr/local/etc/php/conf.d/opcache-recommended.ini

    git clone -b REL1_30 https://gerrit.wikimedia.org/r/p/mediawiki/extensions/VisualEditor.git &&\
    cd VisualEditor &&\
    git submodule update --init

docker-compose文件(也是标准文件，但宽度为仿形):

# MediaWiki with MariaDB
#
# Access via "http://localhost:8024"
#   (or "http://$(docker-machine ip):8024" if using docker-machine)
version: '3'
services:
  mediawiki:
    image: mediawiki31
    restart: always
    ports:
      - 8024:80
    links:
      - database
      - parsoid
    volumes:
      - /var/www/html/images
      # After initial setup, download LocalSettings.php to the same directory as
      # this yaml and uncomment the following line and use compose to restart
      # the mediawiki service
      - ./LocalSettings.php:/var/www/html/LocalSettings.php
  database:
    image: mariadb
    restart: always
    environment:
      # @see https://phabricator.wikimedia.org/source/mediawiki/browse/master/includes/DefaultSettings.php
      MYSQL_DATABASE: my_wiki
      MYSQL_USER: pscn
      MYSQL_PASSWORD: example
      MYSQL_RANDOM_ROOT_PASSWORD: "yes"
  parsoid:
    image: thenets/parsoid:0.9.0
    ports:
      - 8035:8000
    restart: always
    environment:
      PARSOID_DOMAIN_localhost: http://localhost:8024/api.php

我用以下命令编写ffile:docker-compose -f stack.yml up生成LocalSettings.php。
添加到LocalSettings.php:

wfLoadExtension( 'VisualEditor');

$wgDefaultUserOptions['usebetatoolbar'] = 1;
$wgDefaultUserOptions[`usebetatoolbar-cgd`] = 1;
$wgDefaultUserOptions['wikieditor-preview'] = 0;
$wgDefaultUserOptions['wikieditor-publish'] = 0;

#$wgDefaultUserOptions['visualeditor-enable'] = 1;

  if ( $_SERVER['REMOTE_ADDR'] == '127.0.0.1' ) {
     $wgGroupPermissions['*']['read'] = true;
     $wgGroupPermissions['*']['edit'] = true;
    }

$wgVirtualRestConfig['modules']['parsoid'] = array(
    // URL to the Parsoid instance
    // Use port 8142 if you use the Debian package
    'url' => 'localhost:8035',
    // Parsoid "domain", see below (optional)
    'domain' => 'localhost',
    // Parsoid "prefix", see below (optional)
    'prefix' => 'localhost'
);

我打开了维基。一切正常。
我试图打开VisualEditor，但出现错误:

apierror-visualeditor-docserver-http-error: (curl error: 7) Couldn't connect to server. 

和

oldidnotfound: There is no revision with ID 0

我检查了，URL http://localhost:8024/api.php也有内容，URL http://localhost:8035/也有。

哪里有问题？
我什至不知道什么以及如何检查导致问题的原因。

Answer 1

在您的docker-compose.yml中，您在PARSOID_DOMAIN_localhost中有错误

parsoid:
   environment:
   PARSOID_DOMAIN_localhost: http://localhost:8024/api.php

也许localhost:8024-无法在仿形容器中访问。

当我遇到相同的错误时，我已经看到了这样的日志(docker logs -f parsoid)

错误:连接ECONNREFUSED
要么
错误:getaddrinfo ENOTFOUND

然后我更改为

parsoid:
    PARSOID_DOMAIN_localhost: http://docker_wiki_app_host/api.php

它将起作用。
