Requires containers:read and an unscoped admin or analyst. Strix uses the stored credential on the server. GitHub connections list the selected package owner's images only. Older GitHub connections without account selection default to the credential username and accept a namespace override. Docker Hub defaults to the connection username or library for anonymous connections. Google Artifact Registry requires a project-id/repository namespace and artifactregistry.packages.list permission on that repository. Google filters image names before pagination and returns a native page token. Strix does not download the complete Google catalog. ECR uses ecr:DescribeRepositories. Other registries use the OCI catalog, when available. Pull access does not guarantee listing access. If listing fails, callers can still add an image by its reference. ## OpenAPI ````yaml /openapi.json get /containers/registries/{registryId}/repositories openapi: 3.1.0 info: title: Strix API version: 1.0.0 description: >- Public REST API for the Strix autonomous penetration testing platform.
