Registries

Registries store and distribute the artifacts your deployments run — container images, packages, charts. The platform’s implementation is Harbor.

CapabilityWhy it matters
WhitelistingOnly verified packages are permitted, which is where supply-chain risk is actually controlled
Version controlImmutable, addressable versions, so a deploy is reproducible
Access controlPer-team and per-project permissions on push and pull
RevocationWithdraw a compromised artifact from circulation

An artifact registry is the single point every deployment depends on: nothing runs that does not come through it. That makes it both the best place to enforce supply-chain policy and the worst place for an outage.

Whitelisting is the capability that justifies running your own rather than pulling from public registries. A dependency that was fine last month and is compromised today is caught at the registry boundary rather than at every service that pulls it.

Code Quality scans your source and its dependencies for known vulnerabilities before you build. The registry controls what is allowed to be pulled at deploy time. They cover the same risk from opposite ends — one at authoring time, one at runtime — and neither replaces the other.
