Before cleaning the images, you can use the following command to see how much space can be freed:
docker system df
This command will display a summary of the space used by different Docker resource categories, such as images, containers, volumes, and networks.
To free up unused space, we will run the following command:
docker system prune
This command will delete unused images, stopped containers, unused networks, and unused volumes. You will be asked to confirm the deletion before proceeding.
After running the command, you will receive a confirmation showing the amount of reclaimed space. You must confirm the action by typing y or yes and pressing Enter.
Total reclaimed space: XXXMB Are you sure you want to delete all unused containers, networks, and images (yes/no)?
You can check the used space again after cleaning to confirm the space release:
docker system df
Remember that this command permanently deletes resources, so use it with caution to avoid the loss of important data.
