OpenTelemetry Collector v0.164.0 build recipe

The recipe ReadyStack built readystack/otelcol:v0.164.0-CE-ubuntu24.04-r1 from: the upstream source it starts from, every pinned input, and the files that run the build with the network off. Public here: the source and commit, the pinned inputs, all 25 recipe files with their sizes and SHA-256, 9 of them public in full or in part, and the opening lines of the Dockerfile and build script.

An account is an email address, a username and a password: no card, no donation. It opens all 25 recipe files; the build kit itself keeps its own terms.

Fetched once, with the network on, by the vendor step (Dockerfile.vendor) when the kit was made; the offline build uses the kit's vendored copies:

# =============================================================================
# ReadyStack — offline reproducible rebuild.
#
# Rebuilds this product's image from THIS ARCHIVE ALONE, with no network access
# of any kind, and prints the resulting linux/amd64 image-manifest digest.
# Run ./VERIFY_OFFLINE.sh afterwards to assert it equals the published digest.
#
# Requirements: linux/amd64 Docker host, docker buildx >= 0.30, jq, tar.
# No git, no registry access, no additional tooling.

#   ./BUILD_OFFLINE.sh                the rebuild (OCI image + a docker-loadable copy)

#                                     reach, and the result meets SLSA Build Level 3 (see REBUILD.md). The image
