Docker volume plugins and Infinit – Mini-conf Docker Paris #1
2 likes654 views
The document discusses the importance of Docker volumes for managing state within Docker containers, highlighting the balance between reproducibility and statefulness. It explains how Docker volumes allow for persistent state but cautions against breaking determinism guarantees. Additionally, it introduces the Infinit filesystem as a scalable, peer-to-peer storage solution that enhances file management across various resources.

- 5. The need for Docker volumes Docker is awesome to get isolated, predictable environments: • Build and test your project deterministically. • Run your project in a deterministic production environment. This greatness arises from two properties: • Deterministic initial state. • No side effects - get a fresh start every time.

The need for Docker volumes Docker is awesome to get isolated, predictable environments: • Build and test your project deterministically. • Run your project in a deterministic production environment. This greatness arises from two properties: • Deterministic initial state. • No side effects - get a fresh start every time. This makes Docker a purpuree environment.

The need for Docker volumes Pureness is great the vast majority of time, but it can be a burden too - just like with code. • A deterministic build is great, provided you can somehow get your built files. • A deterministic production environment is great, provided you don't require any local state. This is the price of Docker's reproducibility guarantees.
- 11. The need for Docker volumes Docker volumes enable you to alter initial container state and persist state between containers.
- 12. The need for Docker volumes Docker volumes enable you to alter initial container state and persist state between containers. As a consequence: • We can solve our previous issues. • We are breaking the determinism guarantees!
- 13. The need for Docker volumes Docker volumes enable you to alter initial container state and persist state between containers. As a consequence: • We can solve our previous issues. • We are breaking the determinism guarantees! Volumes introduce statefullness, the enemy of reproducibility. Use with care and bound their scope.

- 15. Beyond the local host boundaries Persisting data locally is useful, but there's more.
- 16. Infinit filesystem InfinitInfinit is a peer-to-peer, scalable, reliable, secure filefile ststororageage platfplatformorm that relies on the aggregation of various storage resources (local disk, NAS, SAN, cloud, etc.) on top of which POSIX-compliant file systems can be created.
- 17. Infinit filesystem • Filesystem in the POSIXPOSIX sense of the term. ◦ Works with any client, unmodified. ◦ Fine grained semantic (e.g: video streaming). ◦ Well featured (e.g: file locking).

Infinit filesystem • Filesystem in the POSIXPOSIX sense of the term. ◦ Works with any client, unmodified. ◦ Fine grained semantic (e.g: video streaming). ◦ Well featured (e.g: file locking). • PPeereer-t-too-peer distribut-peer distributeded: no computer has any specific authority or role. ◦ Availability: no SPOF, network failure resilient. ◦ Scalability and flexibility.
