# Runs the EF Core migrations bundle on the leader instance only, before the new
# application version becomes active. The bundle is a self-contained linux-x64
# executable placed at the root of the deployment archive by
# scripts/package-elastic-beanstalk.sh.
#
# The connection string is provided at runtime by the existing Elastic Beanstalk
# environment property ConnectionStrings__DefaultConnection. It must NOT be
# passed on the command line (it would leak into the process table and logs); the
# bundle reads it through the application configuration environment provider.
#
# A non-zero exit fails the deployment (Elastic Beanstalk aborts on container
# command failure), so a migration error never yields a live broken deployment.
