Description

Followed https://github.com/nodejs/docker-node/blob/main/CONTRIBUTING.md

Note: it doesn't look like update.sh is correctly handling the alpine image updates due to a failing checksum fetch for 18.x

Looks like the checksum file for 18.19.0 is missing on unofficial-builds.nodejs.org: https://unofficial-builds.nodejs.org/download/release/v18.19.0/SHASUMS256.txt

Filed nodejs/node#50997. It turns out all release artifacts for 18.19.0 for alpine are missing.

@richardlau has requeued the 18.19.0 release build for us 🙏: nodejs/node#50997 (comment)

OK, alpine images are updated and things look good 💯

This is ready for review 🙏

nvm, this is obviated by #2003
