# Gravl Build Status Checker
|
|
#
|
|
# Purpose:
|
|
# Verifies that deployed containers match the current git HEAD.
|
|
# Warns if containers are stale (built from older commits).
|
|
# Helps you catch situations where code was updated but not redeployed.
|
|
#
|
|
# How it works:
|
|
# 1. Gets current local git commit (HEAD)
|
|
# 2. Queries each container's build labels
|
|
# 3. Compares container label commit vs local HEAD
|
|
# 4. Reports status: "OK", "STALE", or "WARNING"
|
|
#
|
|
# Exit codes:
|
|
# 0 = All checks completed (see output for individual status)
|
|
# (Warnings don't cause non-zero exit)
|
|
#
|
|
# Usage:
|
|
# ./scripts/build-check.sh
|
|
#
|
|
# Example output:
|
|
# Local HEAD: abc1234 (abc1234567890abcdef...)
|
|
#
|
|
# [gravl-backend] Built: abc1234 on 2026-03-03T18:21:00Z
|
|
# [gravl-backend] OK: up to date
|
|
# [gravl-frontend] Built: abc1234 on 2026-03-03T18:21:00Z
|
|
# [gravl-frontend] OK: up to date

#
|

# Label fields used:
|
|
# org.opencontainers.image.revision = commit hash when image was built

# Format: 40-character SHA (same as git rev-parse HEAD)

|
# Set by: scripts/deploy.sh -> docker compose build args

# org.opencontainers.image.created = RFC3339 timestamp when image was built
