You're trying to build a Docker image from the current directory (.) and tag it as openai-whisper. Here's what you can expect:

1. Dockerfile: Make sure there is a file named Dockerfile in your current working directory. This file contains the instructions for building the Docker image.
2. Build process: The docker build command will:
   • Read the instructions from the Dockerfile.
   • Create a new Docker image with the specified tag (openai-whisper).
   • Execute each instruction in the Dockerfile, which may include:
     • Copying files from your local machine to the container.
     • Installing dependencies (e.g., Python packages).
     • Running commands or scripts.
3. Image creation: The build process will create a new Docker image and store it on your local machine.

If everything goes smoothly, you should see an output like this:

Sending build context to Docker daemon  2.048kB
Step 1/2 : FROM python:3.13-slim
 ---> 7b44ac69c2ce
Step 2/2 : COPY . /app
 ---> e7a9b0a8e4f5
Successfully built e7a9b0a8e4f5
Successfully tagged openai-whisper:latest

This indicates that the build process was successful, and you now have a Docker image with the tag openai-whisper and the latest version.

Remember to run docker images or docker ls to verify that the image has been created and is available for use.

A daemon, in this context, refers to a background process that runs continuously, performing tasks without user intervention. To run a daemon from your Docker image, you'll need to:

1. Create a script: Write a shell script (e.g., run-daemon.sh) that contains the commands needed to run your daemon.
2. Copy the script to the container: In your Dockerfile, copy the script file into the container using the COPY instruction:

COPY run-daemon.sh /app/run-daemon.sh

3. Make the script executable: Use the RUN instruction to make the script executable:

RUN chmod +x /app/run-daemon.sh

4. Run the daemon script as a background process: Use the CMD instruction to run the script as a background process:

CMD ["/app/run-daemon.sh", "&"]

The & at the end of the command tells the shell to run the command in the background.

Here's an example Dockerfile snippet:

FROM python:3.13-slim

COPY requirements.txt /app/requirements.txt
RUN pip install -r /app/requirements.txt

COPY run-daemon.sh /app/run-daemon.sh
RUN chmod +x /app/run-daemon.sh

CMD ["/app/run-daemon.sh", "&"]

In this example, the run-daemon.sh script is assumed to be responsible for running your daemon. You'll need to modify the script to contain the necessary commands to run your daemon.

Once you've built and tagged your Docker image, you can start a container from it using:

docker run -d --name my-container openai-whisper

The -d flag runs the container in detached mode (i.e., background). The --name flag assigns a name to the container.
