## What it is
Flocker is an open-source container data volume manager for Dockerized applications, providing portable datasets that follow containers as they move between hosts. It lets ops teams run stateful services like databases in production by managing containers and volumes together.

## Use cases
- run stateful containers like databases in production with docker
- migrate docker volumes between hosts
- make container data volumes portable across a cluster
- manage persistent storage for stateful microservices
- move containers with their data to different servers

## When to choose
- you run a legacy Docker deployment needing portable volumes across hosts
- you want volumes to follow containers during rescheduling on a small cluster

## When to avoid
- you use modern orchestrators like Kubernetes, which has built-in volume management (CSI)
- you need actively maintained software - the project has been abandoned since 2017
- you need multi-cloud or vendor-supported storage orchestration

## Facets
- artifact type: application
- maturity: abandoned
- function: container-orchestration, deployment, file-system, cli
- domain: databases, self-hosted
- platform: python, cli
- tags: docker-volumes, persistent-storage, stateful-containers, data-migration, microservices, containers, devops, linux, docker
