To build the Docker image using this Dockerfile, execute the following command:

\`\`\`bash
docker build -t your_image_name --build-arg IMAGE_VERSION=desired_version .
\`\`\`

Replace \`your_image_name\` with your desired image name and tag, and \`desired_version\` with the desired version of the base image.

To run a container using the built image, use the following command:

\`\`\`bash
docker run -d your_image_name
\`\`\`

This will start a container in detached mode.
