php - Trouble accessing a local process in another docker container -

i'm trying connect rabbitmq docker container php. error i'm getting uncaught exception 'errorexception' message 'stream_socket_client(): php_network_getaddresses: getaddrinfo failed: name or service not known'. think issue how point program rabbitmq process.

the snippet of code think causing error

$connection = new amqpstreamconnection(getenv('message_broker_host'), 5672, 'guest', 'guest'); 

the environment variable i'm accessing defined in .env

message_broker_host=amqp://rabbitmq 

i'm not used docker, under impression should work since process code runs on has rabbitmq linked in docker-compose file "rabbitmq".

the message_broker_host env should rabbitmq without amqp:// because phpamqp-lib not support dsns.

if you'd deal real dsn @ enqueue/amqp-lib.

the code like:

<?php use enqueue\amqplib\amqpconnectionfactory;  $factory = new amqpconnectionfactory('amqp://guest:guest@rabbitmq:5672/%2f');
