=> ↺ How to Deploy Containers with nerdctl - The New Stack

How many ways can you deploy a container? Shall we count them?
Seriously, we don’t have all day.
Really, there are more ways to deploy containers than I can count on my hands. For some, that might be a bit of an overkill situation. For those who like options, however, the idea that there are so many deployment methods is a big plus.

Linux NILFS file system: automatic continuous snapshots

=> ↺ Linux NILFS file system: automatic continuous snapshots

Today, I'll share about a special Linux file system that I really enjoy. It's called NILFS and has been imported into Linux in 2009, so it's not really a new player, despite being stable and used in production it never got popular.
In this file system, there is a unique system of continuous checkpoint creation. A checkpoint is a snapshot of your system at a given point in time, but it can be deleted automatically if some disk space must be reclaimed. A checkpoint can be transformed into a snapshot that will never be removed.
This mechanism works very well for workstations or file servers on which redundancy is nonexistent, and on which backups are done every day/weeks which give room for unrecoverable mistakes.
