You can download it from [Docker's official website](https://docker.com). ## Build Instructions To build the Docker image for this application, run the following command: ```bash docker build -t flask-redirect-app . ``` This will use the `Dockerfile` in the current directory to build an image named `flask-redirect-app`. ## Running the Application Once the image has been built, you can start a container with: ```bash docker run -dp 5000:5000 flask-redirect-app ``` The application will be accessible at `http://localhost:5000` and will redirect to https://dongsiqie.me. ## Stopping the Application To stop the running container, first list all running containers with: ```bash docker ps ``` Find the container running the `flask-redirect-app` and note the CONTAINER ID. Then run: ```bash docker stop CONTAINER_ID ``` Replace `CONTAINER_ID` with the actual ID of your container.
