|
# BEFORE APPLYING:
|
|
# Set the image to your built image, e.g.:
|
|
# youruser/ecommerce-backend:latest (Docker Hub)
|
|
# registry.local:5000/ecommerce-backend:latest (local registry)
|
|
#
|
|
# The init containers:
|
|
# 1. wait-for-postgres — polls until PostgreSQL is accepting connections
|
|
# 2. run-migrations — runs "prisma migrate deploy" once postgres is up
