我在使用laravel 5 / mysql应用程序访问我的docker容器中的adminer时遇到问题.我收到了错误：
SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name does not resolve
我的docker-compose.yml：
version: '3'
services:
votes_app:
build:
context: ./web
dockerfile: Dockerfile.yml
container_name: votes_app_container
environment:
- APACHE_RUN_USER=#1000
volumes:
- ${APP_PATH_HOST}:${APP_PTH_CONTAINER}
ports:
- 8081:80
working_dir: ${APP_PTH_CONTAINER}
votes_db:
image: mysql:5.6.41
container_name: votes_db_container
restart: always
environment:
MYSQL_ROOT_PASSWORD: 1
volumes:
- ${DB_PATH_HOST}:/var/lib/mysql
votes_adminer:
image: adminer
container_name: votes_adminer_container
restart: always
ports:
- 8082:8080
links:
- votes_db
votes_composer:
image: composer:1.6
container_name: votes_composer_container
volumes:
- ${APP_PATH_HOST}:${APP_PTH_CONTAINER}
working_dir: ${APP_PTH_CONTAINER}
command: composer install --ignore-platform-reqs
我为app和db容器提供了不同的端口.
这里https://hub.docker.com/_/adminer/我发现：
Usage with external server You can specify the default host with the
ADMINER_DEFAULT_SERVER environment variable. This is useful if you are
connecting to an external server or a docker container named something
other than the default db.
docker run -p 8080:8080 -e ADMINER_DEFAULT_SERVER=mysql adminer
在我的应用程序的控制台中我运行命令
$docker run -p 8089:8080 -e ADMINER_DEFAULT_SERVER=votes_db adminer
在我的应用程序端口中未使用,并且此命令无论如何都不成功,因为我在尝试登录到adminer https://imgur.com/a/4HCdC1W时遇到了同样的错误.
哪种方法正确？
修改块#2：
在我的docker-compose.yml中：
version: '3'
services:
votes_app:
build:
context: ./web
dockerfile: Dockerfile.yml
container_name: votes_app_container
environment:
- APACHE_RUN_USER=#1000
volumes:
- ${APP_PATH_HOST}:${APP_PTH_CONTAINER}
ports:
- 8081:80
working_dir: ${APP_PTH_CONTAINER}
db:
image: mysql:5.6.41
restart: always
environment:
MYSQL_ROOT_PASSWORD: 1
volumes:
- ${DB_PATH_HOST}:/var/lib/mysql
adminer:
image: adminer
restart: always
ports:
- 8082:8080
links:
- db
votes_composer:
image: composer:1.6
container_name: votes_composer_container
volumes:
- ${APP_PATH_HOST}:${APP_PTH_CONTAINER}
working_dir: ${APP_PTH_CONTAINER}
command: composer install --ignore-platform-reqs
我重建了应用程序,但我没有登录到adminer：https://imgur.com/a/JWVGfBA
我在操作系统的控制台中运行指向其他未使用的8089端口：
$docker run -p 8089:8080 -e ADMINER_DEFAULT_SERVER=db adminer
PHP 7.2.11 Development Server started at Thu Nov 1 07:00:46 2018
[Thu Nov 1 07:01:11 2018] ::ffff:172.17.0.1:34048 [200]: /
[Thu Nov 1 07:01:20 2018] ::ffff:172.17.0.1:34052 [302]: /
[Thu Nov 1 07:01:21 2018] ::ffff:172.17.0.1:34060 [403]: /?server=db&username=root
但再次错误登录到8089端口的adminer,但错误消息不同：

怎么了 ？
修改块#3：
我想是的,因为在我重建了容器之后,我进入了框并在控制台输出中看到“root”：
$docker-compose exec votes_app bash

无论如何它可以成为问题吗？
谢谢！
