Build Options
Selecting a Specific Symfony Version
Use the SYMFONY_VERSION environment variable to select a specific Symfony version.
For instance, use the following command to install Symfony 5.4:
On Linux:
SYMFONY_VERSION=5.4.* docker compose up --build
On Windows:
set SYMFONY_VERSION=5.4.*&& docker compose up --build&set SYMFONY_VERSION=
Installing Development Versions of Symfony
To install a non-stable version of Symfony, use the STABILITY environment variable during the build.
The value must be a valid Composer stability option.
For instance, use the following command to use the development branch of Symfony:
On Linux:
STABILITY=dev docker compose up --build
On Windows:
set STABILITY=dev&& docker compose up --build&set STABILITY=
Customizing the Server Name
Use the SERVER_NAME environment variable to define your custom server name(s).
SERVER_NAME="app.localhost, caddy:80" docker compose up --build
If you use Mercure, keep caddy:80 in the list to allow the PHP container to request the caddy service.
Tips: You can define your server name variable in your .env file to keep it at each up
Using custom HTTP ports
Use the environment variables HTTP_PORT, HTTPS_PORT and/or HTTP3_PORT to adjust the ports to your needs, e.g.
HTTP_PORT=8000 HTTPS_PORT=4443 HTTP3_PORT=4443 docker compose up --build
to access your application on https://localhost:4443.
Note: Let's Encrypt only supports the standard HTTP and HTTPS ports. Creating a Let's Encrypt certificate for another port will not work, you have to use the standard ports or to configure Caddy to use another provider.
