问题：
php_网络_getaddresses:Docker管理员中getaddrinfo失败错误
别开诚
我在使用laravel 5/mysql应用程序访问docker容器中的adminer时遇到问题。我得到一个错误：
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
我为应用程序和数据库容器提供了不同的端口。
这里https://hub.docker.com/_/adminer/我发现：
外部服务器的用法您可以使用ADMINER_DEFAULT_SERVER环境变量指定默认主机。如果要连接到外部服务器或名为默认数据库以外的其他名称的docker容器，这将非常有用。
docker run -p 8080:8080 -e ADMINER_DEFAULT_SERVER=mysql adminer
在我的应用程序的控制台，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使用未使用的，并且该命令无论如何都没有成功，因为我在尝试登录到adminer时遇到了相同的错误https://imgur.com/a/4HCdC1W.
哪条路对？
修改块#2：
在我的码头上。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}
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

votes_composer:

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，但未能登录管理员：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 07:01:21 2018] ::ffff:172.17.0.1:34060 [403]: /?server=db&username=root
但再次错误登录到管理员8089端口，但错误消息是不同的：
https://imgur.com/a/a8qM4bt
怎么了？
修改块#3：
我想是的，因为在我重新构建容器后，我将其输入到框中，并在控制台输出中看到“root”：

这会是个问题吗？
修改块#4
我重新制作了这个docker，我设置了容器的默认名称（我想这引起了一些混乱），我设置了图像：作曲家： 1.8最新版本所以在我的docker-compose.yml：
version: '3.1'
services:
web:
build:
context: ./web
dockerfile: Dockerfile.yml
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:

restart: always
ports:

composer:
image: composer:1.8
volumes:

working_dir: ${APP_PTH_CONTAINER}
command: composer install --ignore-platform-reqs
和在web/Dockerfile中。yml：
FROM php:7.2-apache
RUN apt-get update -y && apt-get install -y libpng-dev nano
RUN docker-php-ext-install \
pdo_mysql \
&& a2enmod \
rewrite
但无论如何重建后的项目和连接到管理员与http://127.0.0.1:8082网址我得到了错误：
SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Try again
附言：我有其他laravel 5.0/php： 5.6/图片：作曲家： 1.6/mcrypt安装docker项目在我的笔记本电脑的同一个本地服务器上，这对我来说工作正常，我可以进入管理员，可以从这个应用程序登录数据库。这个docker项目有文件：
docker-compose.yml：
version: '3.1'
services:

dockerfile: Dockerfile.yml
environment:

和Dockerfile.yml：

RUN apt-get update -y && apt-get install -y libpng-dev nano libmcrypt-dev
RUN docker-php-ext-install \
pdo_mysql \
mcrypt \
&& a2enmod \
rewrite
这个问题是不是PHP7.2特有的特性（比如缺少一些软件包？）
修改块#5：与定义：
phpmyadmin:
depends_on:
- db
image: phpmyadmin/phpmyadmin
restart: always
ports:
- 8082:8080
environment:
PMA_HOST: db
MYSQL_ROOT_PASSWORD: 1
跑步http://127.0.0.1:8082/ 我在浏览器中遇到错误：
This site can’t be reached The webpage at http://127.0.0.1:8082/ might be temporarily down or it may have moved permanently to a new web address.
ERR_SOCKET_NOT_CONNECTED
在尝试应用程序url时http://127.0.0.1:8081/public/ 我得到一个错误：
SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution
修改块#6：我在docker compose中用phpmyadmin重新制作。yml：
version: '3.1'
services:
# docker run -p 8089:8080 -e ADMINER_DEFAULT_SERVER=db adminer
web:
# env_file:
# - ./mysql.env

composer:

volumes:

working_dir: ${APP_PTH_CONTAINER}
command: composer install --ignore-platform-reqs
但试图登录到phpMyAdmin在
http://127.0.0.1:8082
我也犯了同样的错误：https://imgur.com/a/cGeudI6
