How config works

Each unit has one YAML file:

<base>/conf/<unit-name>.yaml

The file name is the unit name.

Unit names

Unit names must use lowercase letters, digits, and single dashes.

Valid names:

myapp
db-main

Validation

Run dpl check before a deploy:

dpl check myapp

This catches:

• invalid YAML fields
• missing referenced units
• wrong unit types
• missing secrets
• unknown reference keys

dpl rejects unknown fields in a unit’s config. This helps find typos early.
