hull config

hull config walks a package’s values.schema.json interactively and writes the answers to a values file.

When to use it

Produce a values file for a package without hand-editing YAML.
Discover a package’s configurable fields by being prompted for each one, with the schema’s type, description, and default shown inline.

What happens

Reads <package-path>/values.schema.json (required; the command fails without it).
Prompts for each property in sorted key order. The prompt shows the type, the description, the default in brackets, and * for required keys. Prompts are written to stderr.
Press Enter to accept the shown default; type a value to override it. Input is validated against the property type (integer, number, boolean, string).
Marshals the collected values to YAML and writes them to --out, or to stdout when --out is -.

No cluster is contacted.

Usage

hull config <package-path> [flags]

Flags

Flag	Type	Default	Description
`-o, --out`	string	”-“	write the values file here; `-` prints to stdout

Worked example

INPUT — webapp/values.schema.json:

{
  "type": "object",
  "required": ["name"],
  "properties": {
    "name":     {"type": "string",  "description": "release name"},
    "replicas": {"type": "integer", "description": "pod count", "default": 2},
    "debug":    {"type": "boolean", "default": false}
  }
}

Session (hull config webapp) — prompts on stderr, your input after each:

debug (boolean) [false]:                    ⏎   (kept the default)
name (string) — release name *: orders
replicas (integer) — pod count [2]: 5

You accepted the debug default, typed orders for the required name, and overrode replicas with 5.

OUTPUT (stdout):

debug: false
name: orders
replicas: 5

debug: false is the schema default you kept; name and replicas are the values you entered. Add -o values.yaml to write the file instead of printing it.
