# preflight/preflight.sh — foundation host & toolchain pre-flight validation.
|
||
|
|
#
|
||
|
|
# PLAN-002 Phase 1 / §9.1: a freshly-cloned repo validates host + toolchain
|
||
|
|
# BEFORE any `pulumi up`. Fails CLOSED: exits NON-ZERO if ANY required check
|
||
|
|
# fails. Composable: one script per concern under checks/, aggregated here.
|
||
|
|
#
|
||
|
|
# Runs on the operator workstation AND in CI, on macOS (bash 3.2) and Linux.
|
||
|
|
# No hard bashisms: no associative arrays, no mapfile, no ${var^^}, no
|
||
|
|
# process substitution.
|
||
|
|
#
|
||
|
|
# USAGE
|
||
|
|
# ./preflight/preflight.sh # run all checks
|
||
|
|
# ./preflight/preflight.sh tools env # run only the named checks
