When populating config values with commands, particularly the random command, it can be useful to suppress the regeneration of the random value in question across your app versions
To stop config values which are generated using the random command from regenerating every time a new app update is installed, make the config item hidden
Example app
cmds:
- name: generate_random_password_32_char
cmd: random
args:
- "32"
...
config:
- name: App
title: "App Configuration"
description: Set default values for my App to Use
items:
- name: admin_pw
title: "Generated Admin User Password"
hidden: true
value_cmd:
name: generate_random_password_32_char
value_at: 0
this approach will hide the value from the customer. To make it visible to the customer while retaining the persistent property, chain config items:
config:
- name: App
title: "App Configuration"
description: Set default values for my App to Use
items:
- name: admin_pw
title: "Generated Admin User Password"
hidden: true
value_cmd:
name: generate_random_password_32_char
value_at: 0
- name: admin_pw_view
title: "The Visible Admin User Password"
type: text
readonly: true
value: '{{repl ConfigOption "admin_pw" }}'
