twelve-factor

Automating Juju charm generation for a 12-factor web application involves assessing the repository framework, generating a rock with rockcraft, and packaging the charm with charmcraft. This Skill coordinates that end-to-end workflow to accelerate production-grade deployments on Kubernetes-backed Juju models.

Converting a monorepo web service into a Kubernetes-backed Juju charm requires running an automated fit assessment to determine the framework and deployment context. This Skill then guides rock and charm generation using a structured handoff payload with minimal manual intervention.

Yes, building 12-factor Juju charms end-to-end requires the paas-charm rockcraft and charmcraft tooling. These tools handle the packaging and generation steps guided by a structured handoff payload to complete the build, push, deploy, and verify cycle.

Framework assessment for packaging a 12-factor app as a Juju charm works by inspecting the repository to determine the application's framework, scope, and deployment context. This automated fit assessment ensures the web service is suitable before proceeding to rock and charm generation.

The 12-factor charm workflow applies specifically to web-service apps deployed on Kubernetes-backed Juju models. It is not designed for non-Kubernetes contexts, as the end-to-end build, push, deploy, and verify cycle relies on Kubernetes-backed deployment infrastructure.

A structured handoff payload in rock and charm generation is a data contract that guides the transition from framework assessment to packaging. It ensures the rockcraft and charmcraft tooling receive the necessary context to formally generate the rock and charm for the 12-factor application.
