Lodestar - Config

The Configuration API for Lodestar.

Runtime Configurations

The base runtime configuration is a Yaml file. The only required contents for the base configuration is the following:

basic_information:
  engagement_types:
    options:
      - label: Type One
        value: TypeOne
      - label: TypeTwo
        value: TypeTwo

The options list in the engagement_types will be used to determine if there are any override files to merge. Base config values can be added to or overriden using override files with the naming scheme <base-file-name>-<engagement_type_value>.yaml.

For example:

If the base configuration name is runtime-config.yaml and you wanted to add to or override values for engagement type TypeTwo, you would need to create a mounted file with the name runtime-config-typetwo.yaml.

If no file found matching the value of the engagement type, the base config will be returned.

Runtime Configuration Merging

  • All entries in the base config and not in the override config will be included
  • All entries in the override config and not in the base config will be included
  • All entries, excluding lists, that are in both the base and override configuration will use the values in the override config
  • Any list that is in both base and override configs will be replaced with the values in the override config
