What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded
The App Container (appc) specification and Go tooling, defining an image format (ACI), runtime environment, and discovery mechanism for application containers. It was the predecessor to the OCI container standards and is no longer actively developed.
Use cases
- work with appc ACI container images
- verify and sign container images cryptographically
- understand the appc container specification
- maintain legacy rkt-based container tooling
- study the history of container image format standards
- implement appc image discovery
When to choose
- you maintain legacy software that depends on the appc/ACI format
- you need historical reference for how appc compared to OCI specifications
When to avoid
- starting any new container project - use OCI image and runtime specifications instead
- you need signing and dependency features not covered by OCI - consider alternatives like sigstore
- you need actively maintained tooling or community support
