Otter is a high-performance opinionated configuration management framework written in Go for servers that run containers.
The data center is moving towards a container-centric world where the role of the host operating system becomes far more static and disposable. Modern configuration management tools (CM) solve some problems but create many more. Existing CM solutions with their complex abstractions and domain specific languages are built for servers with life spans of several months or years. In a container-centric data center the life span of a host operating system should last only as long as it can provide fundamental services without interruption (e.g. docker daemon, networking services, etc).
Otter draws influence from many successful CM systems but drastically simplifies them for the container world. Otter follows the "batteries-included" model to provide configuration support for major container orchestration tools setup following best-practices.
Some features include:
- Declarative state
- File system operations
- Template rendering
- Package management
- Support for installing and configuring major Docker orchestration systems
##Roadmap
Handles the initial bootstrapping of a host OS taking it from a new OS installation to being ready for handling container workload from a container orchestration tool.
Largely concurrent remote execution.
Otter is under active development and is not production-ready
