Expose ports from environment to the host machine

It’s possible to expose ports from the environment to the host machine. This is useful when you want to access the environment from the host machine (eg. you run an application directly on the host machine and you want to access the Magento database.)

To expose ports from the environment to the host machine, add the following line to the project’s .env file.

MYSQL_EXPOSE=true
REDIS_EXPOSE=true
OPENSEARCH_EXPOSE=true
ELASTICSEARCH_EXPOSE=true
RABBITMQ_EXPOSE=true

When it’s done, restart the environment.

reward env down
reward env up

Please note that you cannot expose the same service twice. Eg. if you have MYSQL_EXPOSE=true in one environment and you want to expose mysql from another environment that would cause a port conflict. You have to select a different port using MYSQL_EXPOSE_TARGET.

The same applies for the rest of the services.

The default ports:

MYSQL_EXPOSE_TARGET=3306
REDIS_EXPOSE_TARGET=6379
OPENSEARCH_EXPOSE_TARGET=9200
ELASTICSEARCH_EXPOSE_TARGET=9200
RABBITMQ_EXPOSE_TARGET=5672

Using this method you will be able to reach the database of one environment from another environment.

To do so, you can use host.docker.internal as the mysql host name in the secondary container.
