ARG JRE_VERSION="25"
# Pin the Ubuntu release explicitly. The unsuffixed `-jre` tag floats to the
# latest Ubuntu, which silently drifted to 26.04 (Python 3.14) and broke the
# build: `amazon-ion` (a `kestra` pip dep) has no cp314 wheel, so pip falls back
# to a source build that needs cmake/gcc. 24.04 LTS ships Python 3.12, for which
# a wheel exists. Pinning also keeps the base OS (and its UID layout) stable.

# Ubuntu 24.04+ bases (eclipse-temurin:*-jre) ship a default `ubuntu` user on
# UID/GID 1000, which would push our `useradd` to 1001. Pin kestra to 1000 so
# deployments that assume it (Helm rootless DinD socket group, fsGroup, existing
# PVC ownership) keep working.
