Porter: Bundling Cloud-Native Deployments

by Shriira Press

Deploying real software rarely means running one tool — it means coordinating Terraform, Helm, kubectl, and scripts, each with its own version and secrets. Porter, a CNCF sandbox project, collapses all of that into a single distributable artifact called a bundle. Implementing the Cloud Native Application Bundle (CNAB) specification, it packages the application image, client tools, parameters, credentials, and deployment logic together and publishes them to an ordinary OCI registry. This book covers the problem Porter solves, the CNAB foundation, the porter.yaml manifest, the mixins that adapt existing tools, the build-and-publish pipeline, and running bundles with credentials, parameters, installations, and dependencies — closing with how Porter fits a real cloud-native workflow.
