[I] Invalid interpolation format for command section due to AIRFLOW_UID in docker-compose.yaml 3.0.x [airflow]
givemechocopy opened a new issue, #52959:
URL: https://github.com/apache/airflow/issues/52959
### Apache Airflow version
3.0.2
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
This issue was encountered while running `docker-compose up airflow-init` on an AWS EC2 instance using **Ubuntu 24.04** with **Docker Compose v1.29.2**.
Starting from Airflow 3.0.x(3.0.0, 3.0.1, 3.0.2), the official `docker-compose.yaml` includes a command line using `$(id -u)` to export `AIRFLOW_UID`. However, `docker-compose` interprets `$(...)` as a variable interpolation expression, which leads to the following error:
```bash
ERROR: Invalid interpolation format for "command" option in service "airflow-init: ..."
```

This breaks the execution of `docker-compose up airflow-init`, especially when using Docker Compose v2+.
### What you think should happen instead?
The command line should be updated to escape the dollar sign, like this:
```sh
export AIRFLOW_UID=$$(id -u)
```
This ensures the expression is evaluated in the container shell instead of being interpreted by Docker Compose.
Alternatively, the documentation can recommend using an .env file to predefine AIRFLOW_UID.
### How to reproduce
1. Download the official docker-compose file:
```bash
curl -LfO 'https://airflow.apache.org/docs/apache-airflow/3.0.2/docker-compose.yaml'
```
2. Run the initialization command:
```bash
docker-compose up airflow-init
```
3. Observe the interpolation format error in the terminal.
### Operating System
Ubuntu 24.04.2 LTS (AWS EC2)
### Versions of Apache Airflow Providers
apache/airflow:3.0.2
### Deployment
Docker-Compose
### Deployment details
