Error: failed to solve
The Dockerfile cannot be empty.
Explanation:
This error occurs when the Dockerfile used to build a Docker image is empty. A Dockerfile is a text file that contains instructions to build an image. It typically includes commands to copy source code, install dependencies, and define the environment for the image. If the Dockerfile is empty, there are no instructions to follow, and the build process fails.
Example:
FROM ubuntu:latest # Copy application files COPY . /app # Set working directory WORKDIR /app # Install dependencies RUN apt-get update && apt-get install -y python3 # Define entrypoint command CMD ["python3", "app.py"]
In this example, the Dockerfile starts with a base image of Ubuntu, copies the application files into the container, sets the working directory, installs Python 3 as a dependency, and defines the entrypoint command to run the “app.py” file using Python 3.
