Skalieren des CI / CD-Mono-Repositorys

Gegeben

1. Monorepository basierend auf Lerna und Yarn Workspaces .
2. Ein Dutzend Anwendungen und Dutzende gängiger Pakete für TypeScript, Angular, NodeJS.
3. Hohe Abdeckung mit Tests verschiedener Streifen (modular, Integration, e2e).
4. und Atlassian Bamboo CI / CD .

Aufgabe

Beschleunigen Sie vorhandene Pipelines um das Zweifache (bis zu mindestens einer halben Stunde). Unterwegs erhöht sich die Stabilität auf 90%.

Mit Blick auf die Zukunft werde ich sagen, dass die erforderlichen Indikatoren erreicht wurden.

Für inkrementelle Build- Herna-Filteroptionen :

lerna run build:packages --since --include-merged-tags --include-dependencies

lerna publish (JFrog):

lerna publish patch --yes
# Feature
lerna publish prepatch --yes --no-push --preid "${PREID}"
