502 Bad gateway docker-compose with Traefik, Nginx in Jenkins

Question

我來這里是因為我遇到了與 Jenkins & Docker 相關的問題。

我當前的目標是通過 Jenkins 構建和部署我的 Laravel 應用程序。 我正在使用 dockerfile 集成所有元素以使我的應用程序正常工作。 此外，我使用 Traefik 作為反向代理，通過 HTTPS 和 Nginx 作為服務器訪問我的應用程序。 （通過 conf.d）

為了在 Jenkins 上運行所有內容，我使用了一個 jenkinsfile，它使用了我自己 gitlab 上的資源

當前的問題是，當我啟動 docker-compose 時，我得到一個502 Bad Gateway 。 但是，我可以在我的遠程服務器上運行該應用程序。 (VPS)

Conf.d

server {
listen 80;
index index.php index.html;
error_log  /var/log/nginx/error.log;
access_log /var/log/nginx/access.log;

    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param PATH_INFO $fastcgi_path_info;
}
location / {
    try_files $uri $uri/ /index.php?$query_string;

} }

所以我使用遠程服務器上的 Traefik，它與我在 Jenkins 上使用的 docker-compose 具有相同的網絡。

我通過建議的解決方案在論壇上進行了一百多個測試，沒有任何效果...如果您有想法，我很感興趣。

先感謝您！

編輯：我沒有從遠程服務器上的 traefik 提供網絡。 這和我的 docker-compose.yml 配置一樣

networks:
  fdcks:
    external: true

更新：我終於解決了這個問題。 Jenkins 在“主”節點上工作，所以我在 Jenkins 上創建了一個新節點（從）並將其設置在我的“階段”中，該階段正在部署我的 docker-compose。

 stage('Build&Run env DEV') {
        agent { label 'node(slave)' }
        steps {
            script{
                    sh """
                      docker-compose down
                      php artisan key:generate
                      docker-compose -f docker-compose.yml up -d --build
                """
            }
        }
    }
