## Zero-Chance = Deterministic Deployment
|
|
|
|
|
|
|
|
The Dedupe filesystem flist uses an interface which allows you to create the file system interface in user space, it is a virtual filesystem.
|
|
|
|
Metadata is exposed. The system sees the full tree of the image, but data itself is not there, data is downloaded whenever they are accessed and fully deduped (unique data).

### Benefits
|
|
|
|
- Smart contract for IT
|
|
The smart contract for IT concept is applicable to any workload: containers, VMs, all gateways primitives, volumes, kubernetes and network.
|
|
It is a static agreement between farmer and user about deployment of an IT workload
|
|
- no dynamic behavior for deployment at runtime
|
|
- no process can start unless the files are 100% described on flist level
|
|
|
|
### There are multiple ways to create an flist:
|
|
|
|
- Convert an existing docker image which is hosted on the docker hub
|
|
- Push an archive like a tgz on the hub
|
|
- A library and CLI tool exist to build the flist from scratch: doing it this way, the directory is locally populated, and the flist is then created from the CLI tool
|
|
- A [GitHub action](https://github.com/threefoldtech/publish-flist) allows to build a flist directly from GitHub action, useful for developers on GitHub
