   * Encapsulates the action to be taken when a potential deadlock is encountered. Clients can use

```Dockerfile
CMD ["fastapi", "run", "app/main.py", "--proxy-headers", "--port", "80"]
```

#### Docker Cache { #docker-cache }

There's an important trick in this `Dockerfile`, we first copy the **file with the dependencies alone**, not the rest of the code. Let me tell you why is that.

```Dockerfile
COPY ./requirements.txt /code/requirements.txt
```

-------------------------------------------------

The branch needs to be available on the remote that the BWC makes of the
repository you run the tests from. Using the remote is a handy trick to make
sure that a branch is available and is up to date in the case of multiple runs.

Example:

Say you need to make a change to `master` and have a BWC layer in `5.x`. You
will need to:

```Dockerfile
CMD ["fastapi", "run", "app/main.py", "--proxy-headers", "--port", "80"]
```

#### Docker-Cache { #docker-cache }

In diesem `Dockerfile` gibt es einen wichtigen Trick: Wir kopieren zuerst die **Datei nur mit den Abhängigkeiten**, nicht den Rest des Codes. Lassen Sie mich Ihnen erklären, warum.

```Dockerfile
COPY ./requirements.txt /code/requirements.txt
```
