Config

Reference documentation for Homechart’s configuration
Categories:

Configuration Sources

Configuration is performed using a JSON/Jsonnet configuration file, environment variables, and command line arguments. Configurations from one source will override previous sources, i.e. environment variables override configuration files, command line arguments override environment variables.

Command Line

Every configuration key can be set using -x <a_config_key1>="a value" -x <a_config_key2>="another value", i.e. -x cli_logLevel=debug -x cli_logFormat=kv. Config values can also be set using JSON, i.e. -x cli='{"logLevel": "debug"}'

Command line values override all other sources.

Environment Variables

Every configuration key can be set using homechart_section_key=a value or HOMECHART_section_key=a value, i.e. homechart_cli_logLevel=debug. A special environment variable, homechart_config can be used to specify a complete JSON/Jsonnet configuration.

Environment Variables override a configuration file.

Configuration File

A configuration file be formatted using JSON or Jsonnet. Homechart looks for homechart.jsonnet by default, ascending the directory tree to find it. See the Jsonnet reference for more information. Configuration files are rendered at startup, allowing you to use dynamic Jsonnet functions to dynamically alter the config, i.e.:

local getRecord(type, name, fallback=null) = std.native('getRecord')(type, name, fallback);
local level = getRecord('txt', 'level.candid.dev');

{
  cli: [
    logLevel: level,
  ],
}

You can view the rendered configuration by running homechart config.

webPush

Homechart can use Web Push to send push notifications from Homechart to your devices. Homechart communicates directly to web push services provided by Apple, Google, Mozilla and other standards-compliant endpoints. Additionally, all of the data in the push notification is encrypted between your server and the client–the web push services can’t read it.

You need to generate the VAPID private and public keys to use Web Push. This can be done from the command line, e.g.:

$ ./homechart_linux_amd64 generate-vapid
{
  "privateKey": "VEIYXV6qF_enUzycyQYdplDUgi05UM4lPh_FTzYmwX8",
  "publicKey": "BNh2dabXjc2N8mctezlEm5pd1-1m_kkVZpdNYJl5gtRtdmKNIZvA6IZwYEYSy5UmVr5N7Bt9y9qKCLTp1sc_89c"
}

Or using a container:

$ docker run -it --rm ghcr.io/candiddev/homechart generate-vapid
{
  "privateKey": "VEIYXV6qF_enUzycyQYdplDUgi05UM4lPh_FTzYmwX8",
  "publicKey": "BNh2dabXjc2N8mctezlEm5pd1-1m_kkVZpdNYJl5gtRtdmKNIZvA6IZwYEYSy5UmVr5N7Bt9y9qKCLTp1sc_89c"
}

This command will output the private and public keys you’ll use in the configuration sections below.

vapidPrivateKey

String, the privateKey value from running generate-vapid.

Default: ""

vapidPublicKey

String, the publicKey value from running generate-vapid.

Default: ""
