# Deploying in Production
|
|
|
|
Symfony Docker provides Docker images, and a Docker Compose definition optimized for production usage.
|
|
In this tutorial, we will learn how to deploy our Symfony application on a single server using Docker Compose.
|
|
|
|
## Preparing a Server
|
|
|
|
To deploy your application in production, you need a server.
|
|
In this tutorial we will use a virtual machine provided by DigitalOcean, but any Linux server can work.
|
|
If you already have a Linux server with Docker Compose installed, you can skip straight to [the next section](#configuring-a-domain-name).
|
|
|
|
Otherwise, use [this affiliate link](https://m.do.co/c/5d8aabe3ab80) to get $100 of free credit, create an account, then click on "Create a Droplet".
|
|
Then, click on the "Marketplace" tab under the "Choose an image" section and search for the app named "Docker".
|
|
This will provision an Ubuntu server with the latest versions of Docker and Docker Compose already installed!
|
|
|
|
To test, the cheapest plan will be enough, but for real production usage you'll probably want to pick a plan in the "general purpose" section that will fit your needs.
|
|
|
|
|
|
|
|
You can keep the defaults for other settings, or tweak them according to your needs.
|
|
Don't forget to add your SSH key or to create a password then press the "Finalize and create" button.
|
|
|
|
Then, wait a few seconds while your Droplet is provisioning.
|
|
When your Droplet is ready, use SSH to connect:
|
|
|
|
$ ssh root@<droplet-ip>
|
|
|
|
## Configuring a Domain Name
|
|
|
|
In most cases, you'll want to associate a domain name to your website.
|
|
If you don't own a domain name yet, you'll have to buy one through a registrar.
|
|

|
|
|
|
Then create a DNS record of type `A` for your domain name pointing to the IP address of your server.
|
|
|
|
Example:
|
|
|
|
your-domain-name.example.com. IN A 207.154.233.113
|
|
|
|
Example in Gandi's UI:
|
|
|
|
|
|
|
|
Note: Let's Encrypt, the service used by default by Symfony Docker to automatically generate a TLS certificate doesn't support using bare IP addresses.
|
|
Using a domain name is mandatory to use Let's Encrypt.
|
|
|
|
## Deploying
|
|
|
|
Copy your project on the server using `git clone`, `scp` or any other tool that may fit your need.
|
|
If you use GitHub, you may want to use [a deploy key](https://docs.github.com/en/free-pro-team@latest/developers/overview/managing-deploy-keys#deploy-keys).
|
|
Deploy keys are also [supported by GitLab](https://docs.gitlab.com/ee/user/project/deploy_keys/).
|
|
|
|
Example with Git:
|
|
|
|
$ git clone git@github.com:<username>/<project-name>.git
|
|
|
|
Go into the directory containing your project (`<project-name>`), and start the app in production mode:
|
|
|
|
$ SERVER_NAME=your-domain-name.example.com docker-compose -f docker-compose.yml -f docker-compose.prod.yml up -d
|
|
|
|
Be sure to replace `your-domain-name.example.com` by your actual domain name.
|
|
|
|
Your server is up and running, and a Let's Encrypt HTTPS certificate has been automatically generated for you.
|
|
Go to `https://your-domain-name.example.com` and enjoy!
|
|
|
|
## Disabling HTTPS
|
|
|
|
Alternatively, if you don't want to expose an HTTPS server but only an HTTP one, run the following command:
|
|
|
|
$ SERVER_NAME=:80 docker-compose -f docker-compose.yml -f docker-compose.prod.yml up -d
|
|
|
|
## Deploying on Multiple Nodes
|
|
|
|
If you want to deploy your app on a cluster of machines, you can use [Docker Swarm](https://docs.docker.com/engine/swarm/stack-deploy/),
|
|
which is compatible with the provided Compose files.
