Resizing Docker containers with the Device Mapper plugin

Read Original

This technical article details the process of resizing Docker containers when using the Device Mapper storage plugin, common on RHEL, CentOS, and Fedora. It explains the plugin's use of thin provisioning and snapshots, and warns that the core technique described is now historical. It directs readers to use the modern `--storage-opt` Docker Engine flag for container filesystem size changes.
