preprod-python-helloworld

Sample Python + Alpine project to run “Hello World” inside a Docker container.

Prerequisites

Docker installed on your system.

Build the image

Clone or navigate to the project directory where the Dockerfile and hello.py are located.

1. Build the Docker image by running the following command in the project terminal:

   
   docker build -t python-hello-world:1.0.0 .

   This will create a Docker image named python-hello-world with the tag 1.0.0.

2. Verify the image was built by listing your Docker images. Run:

   docker images

   You should see the python-hello-world image in the list with the version 1.0.0.

3. Run the Docker container Run the image in a new container. You can specify a custom container name by replacing :

   docker run --name <CONTAINER_NAME> -it python-hello-world:1.0.0

   Replace with the name you want to give the container (e.g., hello-container).

4. View the output: Once the container starts, you should see the message:

   Hello World

   This indicates that the Python script executed successfully inside the container.

Cleanup

To stop and remove the container, run the following:

1. Stop the container:

   docker stop <CONTAINER_NAME>

2. Remove the container:

   docker rm <CONTAINER_NAME>
