v2.1.5+node25.8.2 — Node.js 25.8.2 and Registry Publication Fix

[Amnoor]

Runtime Node v2.1.5+node25.8.2

Secure, Distroless, Multi-Arch Node.js Runtime. Built from Scratch.

This is a patch release on the Node.js 25 maintenance line. The Node.js runtime remains 25.8.2, and the image composition, distroless guarantee, runtime defaults, and binary path are unchanged from v2.1.4+node25.8.2. The v2.1.4+node25.8.2 GitHub tag and release were created, but the build-and-publish job failed before any image push step ran, so that version was never published to Docker Hub or GHCR. The failure came from docker/metadata-action@v5 with Unknown flavor entry: debug=false; this release removes those redundant debug=false entries so registry publication works again.

Pull the Image

# Docker Hub — versioned (recommended for production)
docker pull runtimenode/runtime-node:v2.1.5-node25.8.2

# GitHub Container Registry — versioned (recommended for production)
docker pull ghcr.io/runtimes-node/runtime-node:v2.1.5-node25.8.2

Note: Docker registries normalize + to - in tag names. The canonical version tag is v2.1.5+node25.8.2 — the registry tag is v2.1.5-node25.8.2.

What's New

• Removed debug=false from the flavor: block in the Docker meta (version tags + labels) step in .github/workflows/deployment.yml, leaving latest=false intact.
• Removed debug=false from the flavor: block in the Normalize tag (match tag) step in .github/workflows/deployment.yml, leaving latest=false intact.
• Removed debug=false from the flavor: block in the Normalize promote name (floating tag) step in .github/workflows/deployment.yml, leaving latest=false intact.
• Fixed the v2.1.4+node25.8.2 publication failure by removing the unsupported debug=false flavor entry that caused docker/metadata-action@v5 to abort with Unknown flavor entry: debug=false before any registry push occurred.
• Kept the runtime image contents unchanged from v2.1.4+node25.8.2; there are no Dockerfile, dependency, or runtime behavior changes in this release.
