Juju - documentation

Juju is an open-source operator framework for application and infrastructure management.

Operators encapsulate code, intent, and automation of know-how. Operators are modelled on a human operator with deep knowledge of a complex system, and understanding of how it should operate.

Juju encapsulates operator functionality as Charms. Charms (also known as Charmed Operators) are small, shareable, reusable packages.

Juju enables model-driven operations. Rather than describing configuration in complicated recipes, model-driven operations allow you to describe what your software should actually do, expressed in a clean and portable account of intent.


Juju’s components

Juju provides an end-to-end, ready-to-use implementation of the operator pattern. Its components are:


Why Juju?

Juju helps you transition from mere configuration management to application lifecycle management, by transforming your ability to integrate fast-moving open source components into large, complex deployments.

Juju offers:

  • deployment, configuration, scaling, integration, maintenance
  • reusable automated management and application domain knowledge
  • configuration discoverability
  • management of Kubernetes-native, container-native and VM-native applications

Juju provides the tools to turn your model description into a reality, repeatedly, across different clouds and in widely different settings.
