When using Docker Compose, by default, it leverages cached images to speed up container builds. This means that if you make changes to your Dockerfile or the build context, Docker Compose may not rebuild the containers since it assumes that the existing cached images are still valid.

However, in some cases, you may want to force Docker Compose to rebuild all containers, even if the images haven't changed. This could be necessary if you have made changes to the Dockerfile or build context that affect the container's behavior or dependencies.

There are two ways to force Docker Compose to rebuild containers when the Dockerfile changes:

We can use the --force-recreate flag with the docker-composeup command.  This flag tells Docker Compose to recreate all containers, regardless of whether the images have changed or not. It ensures that any modifications made to the Dockerfile or build context are applied and that the containers are rebuilt from scratch.

Here's how you can do it:

Open a terminal or command prompt.

Navigate to the directory where your docker-compose.yml file is located.

Run the following command:
