Deployment wrapper
The packaging layer around an app that shapes how it runs in an environment (startup, isolation, and supporting processes).
Definition
A deployment wrapper is the packaging layer around an application that shapes how it runs in an environment.
Examples include:
- an init system or process supervisor
- a container or virtual machine
- sidecars that add proxying/observability/security
Why wrappers matter
Wrappers change the effective runtime environment: filesystem layout, networking, permissions, identity, limits, startup/shutdown behavior, and what “healthy” means.
