Docker Data Persistence Guide

To update the image and preserve the data, you can follow the steps below:

1. Create a data volume or use an existing data volume to store data. Data volumes can be shared and reused among containers. You can create a data volume using the following command:
2. create a new volume in Docker with the specified name.
3. Run a new container and mount a data volume to a directory within the container. You can use the following command to run the container and mount the data volume:
4. Run the Docker container with the specified volume mounted at the specified directory within the container, using the specified image.
5. Stop and remove the old container. You can use the following command to stop and remove the container:
6. Stop and remove a Docker container using its ID.
7. Update the mirror. You can use the following command to update the mirror:
8. Download the Docker image.
9. Run a new container with a new image, and mount a data volume to the same directory in the container. This can be achieved by using the following command to run the new container and mount the data volume:
10. Run the Docker container with the specified image, mounting a volume with the name “volume_name” to the directory in the container specified by “container_directory”.

This way, the image can be updated while preserving the data. Data volumes allow data to be retained when a container is deleted and reattached in a new container.
