Laravel无法连接到dockerise数据库
我创建了三个容器（PhP-NGINX-MySql）来支持位于主机上的默认laravel项目。
当我尝试从laravel连接到数据库时，出现错误：
Route::get('/', function () { dd(App\User::all()); return view('welcome'); }); SQLSTATE [HY000] [2002] php_network_getaddresses：getaddrinfo失败：名称或服务未知（SQL：select * from
users）
这是我的.env在laravel-5.3.16
DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=33061 DB_DATABASE=homestead DB_USERNAME=homestead DB_PASSWORD=secret
和可靠的剧本：
--- - hosts: localhost environment: PYTHONPATH: /usr/local/lib/python2.7/site-packages/ tasks: - name: get currernt location command: pwd register: my_way - set_fact: host_dir="{{my_way.stdout}}" - name: create image with nginx docker_image: path: /home/demaunt/Jun/dock_click/engie dockerfile: engie.dockerfile name: engie_image - name: create image with php docker_image: path: /home/demaunt/Jun/dock_click/piha dockerfile: piha.dockerfile name: piha_image - name: run piha container docker_container: name: piha_cont image: piha_image volumes: - "/home/demaunt/Dockjun/laravel-5.3.16:/var/www/wapclick" links: - diba_cont:db env: DB_PORT: 3306 DB_HOST: database - name: run engie container docker_container: name: engie_cont image: engie_image volumes_from: - piha_cont ports: - "8080:80" links: - piha_cont:app - name: run diba container docker_container: name: diba_cont image: mysql:5.6 env: MYSQL_DATABASE: homestead MYSQL_USER: homestead MYSQL_PASSWORD: secret MYSQL_ROOT_PASSWORD: secret ports: - 33061:3306
更奇怪的是，当我运行php artisan迁移时，我得到了succesfull消息：
Migration table created successfully. Migrated: 2014_10_12_000000_create_users_table Migrated: 2014_10_12_100000_create_password_resets_table
这里是运行的容器：
docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES e926382db347 engie_image "nginx -g 'daemon ..." 19 seconds ago Up 18 seconds 443/tcp, 0.0.0.0:8080->80/tcp engie_cont c9563c839e45 piha_image "docker-php-entryp..." 19 seconds ago Up 18 seconds 9000/tcp piha_cont 5de541049da2 mysql:5.6 "docker-entrypoint..." 20 seconds ago Up 19 seconds 0.0.0.0:33061->3306/tcp diba_cont
尝试“diba_cont”作为DB_HOST应该做的工作。 Docker会自动声明一个DNS容器的名称与容器的联系
