invalid interpolation format for services.php.environment.TRUSTED_HOSTS.

What happened?

Hy, i have an issue when trying to build the project for the first time. I get the following error:

invalid interpolation format for services.php.environment.MERCURE_PUBLIC_URL.
You may need to escape any $ with another $.
https://${SERVER_NAME:-localhost

Environment:

• OS: Linux Mint
• Docker version: Docker version 26.1.2, build 211e74b

Steps to Reproduce:

1. Clone the repository.
2. Run docker compose build --no-cache.

Expected Result:

The project should build without any errors.

Actual Result:

The build fails with the following error message:

invalid interpolation format for services.php.environment.MERCURE_PUBLIC_URL.
You may need to escape any $ with another $.
https://${SERVER_NAME:-localhost

Temporary Fix:

To fix the issue, I modified a line in the docker-compose.yaml file:

Old:

TRUSTED_HOSTS: ${TRUSTED_HOSTS:-^${SERVER_NAME:-example\.com|localhost}|php$$}

New:

TRUSTED_HOSTS: ${TRUSTED_HOSTS:-^$${SERVER_NAME:-example\.com|localhost}|php$$}

Question:

Is this a global issue or just limited to a certain configuration?

It's unrelated to FrankenPHP, upgrading Docker Compose will fix the issue: dunglas/symfony-docker#616
