# bin/rollback.sh — roll OmniRoute back to a previous release to mitigate a bad
|
|
# deploy. Part of the deploy-rollback incident-recovery flow.
|
|
#
|
|
# Methods (auto-detected; override with --method):
|
|
# • npm — `npm install -g omniroute@<version>` and, if PM2 manages it,
|
|
# `pm2 restart omniroute`. This is how the VPS deploy runs.
|
|
# • docker — re-tag the local image omniroute:<version> to omniroute:prod and
|
|
# recreate the prod service from docker-compose.prod.yml. (That
|
|
# compose builds the `prod` tag locally rather than pulling a
|
|
# registry tag, so the versioned image must already exist locally.)
|
|
# With no <version>, targets the highest published release strictly below the
|
|
# current package.json version.

Usage: bin/rollback.sh [<version>] [--method npm|docker] [--yes|-y] [-h|--help]
|
|
|
|
Rolls OmniRoute back to <version> (e.g. 3.8.35 or v3.8.35). With no version,
|
|
picks the highest published release below the current package.json version.
|
|
Auto-detects npm vs docker deployment; override with --method.
