Alpine 3.19 was released in December 2023 and typically receives security updates for approximately 2 years. By February 2026, this version may be approaching or past its end-of-life for security support. While this downgrade is necessary for gh CLI availability, consider monitoring Alpine package repositories for when gh CLI support is restored in newer versions (3.20+). You may want to add a reminder or tracking issue to upgrade once a newer Alpine version with gh CLI support becomes available.

Suggested change
FROM alpine:3.19
# TODO(security): Monitor Alpine releases and upgrade to 3.20+ once the `gh` CLI package is available again.
ARG ALPINE_VERSION=3.19
FROM alpine:${ALPINE_VERSION}
