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.
// save this in a file called "ray.php"<?phpreturn [
* 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 where your docker-compose.yml is located (you can find this by running pwd inside that directoy if you are on Linux).
On Linux, you will also need to add an 'extra_hosts' parameter to your container definitions to expose 'host.docker.internal'. Please make sure you are using Docker 20.03 or higher.
