Source controller

The source-controller is a Kubernetes operator, specialised in artifacts acquisition from external sources such as Git, OCI, Helm repositories and S3-compatible buckets. The source-controller implements the source.toolkit.fluxcd.io API and is a core component of the GitOps toolkit.

APIs

Kind	API Version
GitRepository	source.toolkit.fluxcd.io/v1
OCIRepository	source.toolkit.fluxcd.io/v1beta2
HelmRepository	source.toolkit.fluxcd.io/v1
HelmChart	source.toolkit.fluxcd.io/v1
Bucket	source.toolkit.fluxcd.io/v1

Features

• authenticates to sources (SSH, user/password, API token, Workload Identity)
• validates source authenticity (PGP, Cosign, Notation)
• detects source changes based on update policies (semver)
• fetches resources on-demand and on-a-schedule
• packages the fetched resources into a well-known format (tar.gz, yaml)
• makes the artifacts addressable by their source identifier (sha, version, ts)
• makes the artifacts available in-cluster to interested 3rd parties
• notifies interested 3rd parties of source changes and availability (status conditions, events, hooks)
• reacts to Git, Helm and OCI artifacts push events (via notification-controller)
