在gitlab上的docker容器中运行laravel-黄昏时，我收到一个错误，说它无法连接到localhost上的9515端口。
Failed to connect to localhost port 9515: Connection refused
我的docker文件如下所示：

然后我的gitlab ci文件看起来如下：
image: registry.gitlab.com/path-to-repo/repo-name:latest
# Select what we should cache
cache:
paths:
- vendor/
services:
- mysql:5.7
variables:
# Configure mysql service (https://hub.docker.com/_/mysql/)
MYSQL_DATABASE: database-name
MYSQL_ROOT_PASSWORD: database-password
DB_HOST: mysql
DB_USERNAME: root
stages:
- test
unit_test:
stage: test
script:
- cp .env.runnable .env
- composer install
- php artisan config:clear
- php artisan key:generate
- php artisan migrate --seed
- php artisan db:seed --class=TestSeeder
- vendor/bin/phpunit --coverage-text --colors=never
- php artisan env
- php artisan dusk
起初我以为这是因为我没有暴露9515端口，但我已经在Dockerfile中暴露了这一点。然而，现在我不知道可能是什么问题。这个端口用于另一个进程是否存在问题？可能是Chromedriver在另一个端口上运行吗？
在gitlab ci文件中，尝试将php artisan dusk替换为：
php artisan serve & php artisan dusk
我收到9515连接被拒绝的错误，然后我发现了这个GitHub问题，并将这些依赖项添加到我的dockerfile中(允许我使用自定义的ubuntu映像)。我不需要添加GitHub评论中提到的任何其他内容(没有脚本等)。
FROM ubuntu:18.04

apt-get -y install xfonts-cyrillic xfonts-100dpi xfonts-75dpi xfonts-base xfonts-scalable &&
apt-get -y install imagemagick x11-apps &&
apt-get upgrade -y &&
apt-get clean &&
rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /usr/share/doc/*
此外，为了进行本地开发，我需要更新我的.env(或使用.env.dusk.local)APP_URL:以指向我的docker主机。
APP_URL=host.docker.internal:8000
对于GitLab，您可以尝试使用docker主机更新.envAPP_URL，方法是在before_script中添加额外的设置(在将.env.example复制到.env之后)。(host.docker.internal在linux的docker中不可用)。另外，请注意，容器需要net-tools才能执行netstat命令。
before_script:
# ...
- docker_host=$(netstat -nr | grep '^0.0.0.0' | awk '{print $2}') && sed -i "s|APP_URL=http://0.0.0.0|APP_URL=http://${docker_host}|" .env
其中APP_URL=http://0.0.0.0是现有.env文件中已经存在的值。
