lay¶

Field	Value
Purpose	Package and application installer — installs packages, applications, JARs, and container images
Repo	AmadlaOrg/lay

Overview¶

lay handles installation: packages via system package managers, applications, JAR files, and container image pull/build. For containers, lay takes care of building and pulling — waiter handles the rest (Quadlet setup, deployment strategies).

Commands¶

Command	Description
`lay install`	Install applications from entity requirements
`lay settings`	Manage lay configuration

Dependencies¶

Library	Purpose
LibraryUtils	File operations, configuration
LibraryFramework	CLI framework

Pipeline Position¶

lay sits after raise (infrastructure provisioning). For containers, its output (image reference entity) feeds into waiter for deployment.

hery → doorman → raise → [lay] → waiter
                           │
                    pull/build container image
                    install packages/JARs
                    output: image ref entity

Responsibility Split with waiter¶

Concern	Tool
Pull container image	lay
Build container image	lay
Install system packages	lay
Install JAR applications	lay
Deploy with strategy	waiter

Entity Types¶

Entity	What lay Does
Package	Installs packages via the appropriate package manager
Application	Installs applications, JAR files, and container images
ProgrammingLanguage	Installs language runtimes and version managers
Container	Pulls or builds container images

Output¶

When pulling or building container images, lay outputs an entity with the image reference that waiter can consume:

lay pull my-app:v2 | waiter deploy --strategy canary

Current Status¶

42 packages, all tests passing
Idiomatic Go names
JAR application support (binary/jar/)
--name flag for targeted installation
