Flocker vs Weave: What are the differences?
What is Flocker? Run your databases in Docker and make them as portable as the rest of your app. Flocker is a data volume manager and multi-host Docker cluster management tool. With it you can control your data using the same tools you use for your stateless applications. This means that you can run your databases, queues and key-value stores in Docker and move them around as easily as the rest of your app.
What is Weave? Weave creates a virtual network that connects Docker containers deployed across multiple hosts. Weave can traverse firewalls and operate in partially connected networks. Traffic can be encrypted, allowing hosts to be connected across an untrusted network. With weave you can easily construct applications consisting of multiple containers, running anywhere.
Flocker and Weave can be primarily classified as "Container" tools.
"Open-Source" is the primary reason why developers consider Flocker over the competitors, whereas "Easy setup" was stated as the key factor in picking Weave.
Flocker and Weave are both open source tools. It seems that Weave with 5.56K GitHub stars and 512 forks on GitHub has more adoption than Flocker with 3.18K GitHub stars and 287 GitHub forks.
