There are a few ways to edit files in a Docker container when it's down/not started.

**Use a Dockerfile:** A Dockerfile is a text file that contains the instructions for building a Docker image. You can use a Dockerfile to create a Docker image that includes the files you need to edit. Once you have created the Docker image, you can start the container and edit the files.

**Use a volume:** A volume is a directory that is shared between the host machine and the Docker container. You can use a volume to mount a directory from the host machine to the container. Once you have mounted the directory, you can edit the files in the directory from the host machine.

**Use a third-party tool:** There are a number of third-party tools that can help you edit files in Docker containers. Some of these tools include:

- Portainer: https://www.portainer.io/: A web-based UI for managing Docker containers.
- Docker Desktop: https://www.docker.com/products/docker-desktop: A desktop application for managing Docker containers.
- Docker Hub: https://hub.docker.com/: A registry for Docker images.

The best way to edit files in a Docker container when it's down/not started depends on the specific situation. If you are comfortable using the command line, then using a Dockerfile or a volume is the easiest way to do it. If you want to use a graphical user interface, then you can use a third-party tool like Portainer or Docker Desktop.

Here are the steps on how to edit files in a Docker container using a Dockerfile:

1. Create a Dockerfile.
2. In the Dockerfile, specify the files you need to edit.
3. Build the Docker image.
4. Start the container.
5. Edit the files in the container.

Here is an example of a Dockerfile that you can use to edit files in a Docker container:

```plaintext
FROM ubuntu:latest

RUN apt-get update && apt-get install -y nano

COPY myfile.txt /app/

CMD nano /app/myfile.txt
```

This Dockerfile will create a Docker image that includes the nano text editor. The `CMD` instruction tells the Docker image to start the nano text editor when the container is started.

To build the Docker image, you can run the following command:

```plaintext
docker build -t myimage .
```

To start the container, you can run the following command:

```plaintext
docker run -it myimage
```

Once the container is started, you can edit the file `myfile.txt` using the nano text editor.
