我正在尝试使用php中的phpredis建立从http服务器容器到redis容器的连接。
这是撰写文件:
version: '3'
services:
arcade:
build:
context: .
args:
- HOST_IP=${HOST_IP}
- XDEBUG_PORT=${XDEBUG_PORT}
image: arcade-dev:latest
ports:
- "80:80"
volumes:
- ../../..:/var/www/localhost/htdocs
links:
- marry
networks:
- arcade_net
marry:
image: mariadb
ports:
- "3306:3306"
environment:
- MYSQL_ROOT_PASSWORD=s3cr3t
volumes:
- arcade_data:/var/lib/mysql
networks:
- arcade_net
arcade_cache:
image: redis
volumes:
- arcade_cache_data:/data
ports:
- "6379:6379"
networks:
- arcade_net
volumes:
arcade_data: {}
arcade_cache_data: {}
networks:
arcade_net:
driver: bridge
这是redis客户端设置:
use Redis;
final class ArcadeCache
{
public static function getClient(): Redis
{
$redis = new Redis();
$redis->connect('arcade_cache');
return $redis;
}
}
这是我用phpunit来测试连接的一个测试
public function testRedisConnection(): void
{
$client = ArcadeCache::getClient();
$client->append('testKey', 'BAZINGA');
$bazinga = $client->get('testKey');
$this->assertEquals('BAZINGA', $bazinga);
}
当我运行测试(使用“arcade”服务的映像构建)时,我得到以下错误:
RedisException : php_network_getaddresses: getaddrinfo failed: Name does not resolve
/opt/project/Infrastructure/ArcadeCache.php:14
/opt/project/Tests/Infrastructure/ArcadeCacheTest.php:22
Caused by
PHPUnit\Framework\Error\Warning: Redis::connect(): php_network_getaddresses: getaddrinfo failed: Name does not resolve
/opt/project/Infrastructure/ArcadeCache.php:14
/opt/project/Tests/Infrastructure/ArcadeCacheTest.php:22
当我'exec'到http服务器容器'arcade\u cache'时,主机名被正确解析
bash-5.0# ping arcade_cache
PING arcade_cache (172.28.0.3): 56 data bytes
64 bytes from 172.28.0.3: seq=0 ttl=64 time=0.152 ms
64 bytes from 172.28.0.3: seq=1 ttl=64 time=0.080 ms
当我尝试使用ip时( $redis->connect('172.28.0.3');
)而不是主机名连接超时:
RedisException : Operation timed out
/opt/project/Infrastructure/ArcadeCache.php:14
/opt/project/Tests/Infrastructure/ArcadeCacheTest.php:21
Time: 1.05 minutes, Memory: 6.00 MB
ERRORS!

Process finished with exit code 2
使用“marry”主机名连接到db工作正常。
有什么想法吗?
