When developing using Docker, the Ray host should point to the internal IP of your Docker host by using 'host.docker.internal' in the config file.
<?php// Save this in a file called "ray.php"return [/* * The host used to communicate with the Ray app. */'host'=>'host.docker.internal',/* * The port number used to communicate with the Ray app. */'port'=>23517,/* * Absolute base path for your sites or projects in Homestead, Vagrant, Docker, or another remote development server. */'remote_path'=>null,/* * Absolute base path for your sites or projects on your local computer where your IDE or code editor is running on. */'local_path'=>null,];
To make sure that Ray uses the correct file path for creating the links, you will also need to setup the remote_path and local_path variables. remote_path is the absolute path of your project in the Docker container. local_path is the absolute path of your project on the local file system.
In your docker-compose.yml you mount the volume as follows:
Then remote_path should be /var/www and local_path should be the absolute path to the directory that you
mount as /var/www, which is where your docker-compose.yml is located in the example (you can find this by
running pwd inside that directory if you are on Linux).
Add 127.0.0.1 host.docker.internal to /etc/hostsfile.
On Linux, you will also need to add an 'extra_hosts' parameter to your PHP container definitions to expose 'host.docker.internal'. Please make sure you are using Docker 20.03 or higher.
