WalkthroughThe Docker base image in development/docker/Dockerfile was updated from node:16 to node:20. All other Dockerfile instructions, including Ruby/rbenv setup and npm prefix configuration, remain unchanged. No exported or public entities were modified. Changes

15-16: Ruby 2.6.1 is EOL and incompatible with OpenSSL 3 (on bookworm)If keeping
FROM node:20(bookworm), Ruby 2.6.1 will not build due to OpenSSL 3. Consider:
- Preferred: Upgrade Ruby to ≥ 3.1 (e.g., 3.2.x or 3.3.x), which supports OpenSSL 3.
- Interim: Keep Ruby 2.6.1 and use a bullseye-based image as suggested on Line 1.
Example if upgrading Ruby:
-ARG RUBY_VERSION=2.6.1 +ARG RUBY_VERSION=3.2.5Verify downstream tooling, gems, and app code are compatible before bumping Ruby.
13-13: Pin rbenv-installer to a specific revision for supply-chain stabilityFetching the installer via a moving HEAD on raw GitHub can change over time. Pin to a commit SHA and enforce TLS settings.
Example:
- curl -sL https://github.com/rbenv/rbenv-installer/raw/main/bin/rbenv-installer | bash - + curl -fsSL --proto '=https' --tlsv1.2 \ + https://raw.githubusercontent.com/rbenv/rbenv-installer/<pinned-commit>/bin/rbenv-installer | bash -Replace with a vetted commit hash.

Pin Debian variant to avoid Ruby 2.6/OpenSSL 3 build breakage
node:20 defaults to a newer Debian (commonly bookworm) with OpenSSL 3. Ruby 2.6.1 cannot build against OpenSSL 3 and will fail during rbenv install. Either upgrade Ruby to a version supporting OpenSSL 3 (Ruby ≥ 3.1), or pin the base image to a Debian release that still ships OpenSSL 1.1 (bullseye) for compatibility.
Minimal change to keep current Ruby working:
-FROM node:20
+FROM node:20-bullseyeIf you prefer upgrading Ruby instead, see my note on Lines 15-16.

#!/bin/bash

🌐 Web query:
Which Debian release is the official Docker Hub “node:20” image based on by default?
💡 Result:
The official node:20 image is Debian 12 — the "bookworm" release (i.e. node:20 → node:20-bookworm by default). (github.com)
(If you need a different Debian base or a smaller image, use an explicit tag such as node:20-bookworm-slim, node:20-bullseye, or node:20-slim.)
Citations:
Pin Docker base image to Debian Bullseye for Ruby 2.6.1 compatibility
Ruby 2.6.1 installed via rbenv cannot compile against OpenSSL 3 in Debian 12 (Bookworm). To keep the existing Ruby version working, pin the Node 20 image to Bullseye (which ships OpenSSL 1.1).

It appears Github CI and CircleCI have all been upgraded to v20.
