Trow is a lightweight OCI-compliant container image registry written in Rust that runs inside a Kubernetes cluster. It caches external images locally and enforces approve/deny lists via an admission webhook to control which images can run in the cluster.
Use cases
- run a self-hosted container registry inside my kubernetes cluster
- cache docker images locally to speed up pulls and avoid rate limits
- restrict which container images are allowed to run in the cluster
- proxy and cache images from external registries like docker hub
- set up a lightweight private registry with a helm chart
- prevent unauthorized images from being deployed to kubernetes
When to choose
- you run Kubernetes and want a small in-cluster registry with pull-through caching
- you need to lock down cluster images with allow/deny admission control
- you want a simple, low-resource OCI registry without running a heavyweight solution like Harbor
When to avoid
- you need high availability or distributed registry architecture (still on the roadmap)
- you require full auditing and authentication of image access (planned, not implemented)
- you need a general-purpose registry outside Kubernetes with mature enterprise features
