Multiple Fly Applications
This guide discusses how to manage multiple Fly applications within a Laravel project. This is useful for Laravel projects that need to run other services, like running a Redis service for queues, cache, and session storage.
What Is a Fly Application?
Your Laravel application is a Fly application, which means it has the following few things:
fly.tomlfile in the root directory
Dockerfilein the root directory that describes the image
- A "server" running on Fly's infrastructure.
So how do you spin up multiple Fly applications for a single Laravel project?
Creating a Fly Application Within a Fly Application
The important thing about creating multiple Fly applications within a project is keeping them organized. For our example, we'll setup a Laravel server application and keep it in the
./fly/applications folder within our project repo.
Let's get started by running the following commands:
# Further reference: https://fly.io/laravel-bytes/full-stack-laravel/ mkdir -p fly/applications/redis cd fly/applications/redis
From inside the
fly/applications/redis folder, run:
fly launch --image flyio/redis:6.2.6 --no-deploy --name my-project-name-redis
This command will create a
fly.toml file that can be further configured for your application's needs.
Next, we can do some light configuration and then deploy the application:
# Add a required redis password # (note this means using this password when connecting to Redis from your apps) fly secrets set REDIS_PASSWORD=mypassword # Add a volume so deploys of this redis app dont lose data flyctl volumes create redis_server # Configure the volume mount in fly.toml cat <<EOT >> fly.toml [mounts] source = "redis_server" destination = "/data" EOT # Deploy it! fly deploy
Accessing From the Root Application
Fly creates DNS hosts for each of your applications based on the application name. For this example, we can reach the Redis instance via hostname
In the future, when it's time to deploy updates to your Fly application within a Fly application, run:
cd fly/application/redis fly deploy
