"github repo should have: golang 1.23, redis:7, memcached:1.6, postgres:16, make and a protobuf toolchain — protoc plus the Go plugins (protoc-gen-go, protoc-gen-go-grpc). The service speaks gRPC. find more repos that have those exact properties"
Ten diverse exact-stack queries produced 390 URL-deduplicated pages. Each was checked for the exact image tags, Go version, gRPC signals and the protobuf toolchain. No public repository could be verified as having every property at once. That is a verified count of zero within these 390 pages — not proof that none exists anywhere on GitHub, since search indexing and page visibility are incomplete.

Redis, Memcached and PostgreSQL are rarely all runtime dependencies of one focused interview service. If these images are workstation pre-pulls rather than dependencies of a single repository, relax the search to the essentials — a Go 1.23 gRPC service with make and the protoc + protoc-gen-go + protoc-gen-go-grpc toolchain — and treat the datastore images as environment setup.
Method: 10 exact-stack web queries against public GitHub-indexed pages, 390 pages after URL deduplication; each page checked for literal image tags (redis:7, memcached:1.6, postgres:16), Go 1.23, gRPC terms and the protobuf toolchain, then semantically filtered. Aggregate counts come from the check summary (5 rows); false-positive detail from 3 flagged pages; candidate extraction from 8 pages. "0 verified" describes this scan, not all of GitHub. Pages without any signal were cut for space.
