How to deploy a Symfony app | Ample
The short version
To deploy a Symfony app on Ample, run ample deploy . --name <app-name> --public in the project directory, or ask your coding agent to deploy it to Ample. Ample builds it on the php-8.5 template, runs the tested start command below and returns a public HTTPS URL.
Deploy Symfony
- 1
Ask your coding agent
Install the Ample CLI and create an account (no browser or card needed), then ask Claude Code, Codex, Cursor or any agent with a shell to deploy the project. See Ample for coding agents.
curl -fsSL https://get.ample.computer/install.sh | sh
ample auth signup
# then, in your agent:
# "Deploy this Symfony app to Ample"
- 2
Or deploy from the CLI
Run the deploy once from the project directory. It waits until the app is live or failed and prints the URL; exit 0 is live, 1 failed, 2 needs input.
ample deploy . --name <app-name> --public
- 3
Or use MCP
Agents connected to the Ample MCP server (https://api.ample.computer/mcp, or ample mcp over stdio) call ample_deploy with the same arguments.
- 4
Verify
Open the URL. If the deploy failed, read the build log, then the runtime log, fix the cause and deploy again.
ample logs <deployment_id> --kind build

Verified on Symfony: the app built and started with the documented commands and answered on its public HTTPS URL. Build and start: composer install --no-dev from composer.lock with Symfony Runtime's dotenv disabled (extra.runtime.disable_dotenv; .env never ships, its values arrive as encrypted env, and compile-time parameters such as DEFAULT_URI need a default), then FrankenPHP serving public/ (php-server with the index.php fallback) reading PORT on the php-8.5 template with APP_ENV=prod.
Before you deploy
You need
- A Symfony project (composer install --no-dev from composer.lock with Symfony Runtime's dotenv disabled (extra.runtime.disable_dotenv; .env never ships, its values arrive as encrypted env, and compile-time parameters such as DEFAULT_URI need a default), then FrankenPHP serving public/ (php-server with the index.php fallback) reading PORT on the php-8.5 template with APP_ENV=prod)
- An Ample account token with servers:write
Know the limits
- Verified on the php-8.5 template at s-1vcpu-1gb; other sizes and Symfony major versions are not verified.
Frequently asked questions
Do I need a Dockerfile to deploy Symfony?
No. Ample detects Symfony from the repository and builds it from source on the php-8.5 template. Dockerfile build steps are not run.
How do I add a database to a Symfony app?
Leave DATABASE_URL unset and deploy: when the code needs Postgres, MySQL, Redis or MongoDB, Ample creates a managed database and passes its connection string to the app. See Connect Postgres for Symfony.
What does it cost to host a Symfony app on Ample?
The Free plan runs 2 apps at once with no card and a hard monthly budget, so it never bills you. Larger needs are priced on volume; see pricing.
What if the deploy fails?
ample deploy waits until the app is live or failed. A failure returns who must act, a diagnosis and a suggested fix; read the logs with ample logs <deployment_id> --kind build. See Diagnose deployment failures for Symfony.
