Creating a feature flag configuration profile (command line)

The following procedure describes how to use the Amazon Command Line Interface (on Linux or Windows) or Tools for Windows PowerShell to create an Amazon AppConfig feature flag configuration profile. At the time you create the configuration profile, you can also create a basic feature flag.

To create a feature flag configuration

  1. Open the Amazon CLI.

  2. Create a feature flag configuration profile specifying its Type as AWS.AppConfig.FeatureFlags. The configuration profile must use hosted for the location URI.

    Linux
    aws appconfig create-configuration-profile \
  --application-id APPLICATION_ID \
  --name CONFIGURATION_PROFILE_NAME \
  --location-uri hosted \
  --type AWS.AppConfig.FeatureFlags
    Windows
    aws appconfig create-configuration-profile ^
  --application-id APPLICATION_ID ^
  --name CONFIGURATION_PROFILE_NAME ^
  --location-uri hosted ^
  --type AWS.AppConfig.FeatureFlags
    PowerShell
    New-APPCConfigurationProfile `
  -Name CONFIGURATION_PROFILE_NAME `
  -ApplicationId APPLICATION_ID `
  -LocationUri hosted `
  -Type AWS.AppConfig.FeatureFlags

  3. Create your feature flag configuration data. Your data must be in a JSON format and conform to the AWS.AppConfig.FeatureFlags JSON schema. For more information about the schema, see Type reference for AWS.AppConfig.FeatureFlags.

  4. Use the CreateHostedConfigurationVersion API to save your feature flag configuration data to Amazon AppConfig.

    Linux
    aws appconfig create-hosted-configuration-version \
  --application-id APPLICATION_ID \
  --configuration-profile-id CONFIGURATION_PROFILE_ID \
  --content-type "application/json" \
  --content file://path/to/feature_flag_configuration_data.json \
    Windows
    aws appconfig create-hosted-configuration-version ^
  --application-id APPLICATION_ID ^
  --configuration-profile-id CONFIGURATION_PROFILE_ID ^
  --content-type "application/json" ^
  --content file://path/to/feature_flag_configuration_data.json ^
    PowerShell
    New-APPCHostedConfigurationVersion `
  -ApplicationId APPLICATION_ID `
  -ConfigurationProfileId CONFIGURATION_PROFILE_ID `
  -ContentType "application/json" `
  -Content file://path/to/feature_flag_configuration_data.json `

    The content parameter uses base64 encoded data, similar to the following example.

    {
    "flags": {
        "ui_refresh": {
            "name": "UI Refresh"
        }
    },
    "values": {
        "ui_refresh": {
            "enabled": false,
            "attributeValues": {
                "dark_mode_support": true
            }
        }
    },
    "version": "1"
}

    The system returns information like the following.

    Linux
    {
   "ApplicationId"          : "ui_refresh",
   "ConfigurationProfileId" : "UI Refresh",
   "VersionNumber"          : "1",
   "ContentType"            : "application/json"
}
    Windows
    {
   "ApplicationId"          : "ui_refresh",
   "ConfigurationProfileId" : "UI Refresh",
   "VersionNumber"          : "1",
   "ContentType"            : "application/json"
}
    PowerShell
    ApplicationId          : ui_refresh
ConfigurationProfileId : UI Refresh
VersionNumber          : 1
ContentType            : application/json

    The service_returned_content_file contains your configuration data that includes some Amazon AppConfig generated metadata.

    Note

    When you create the hosted configuration version, Amazon AppConfig verifies that your data conforms to the AWS.AppConfig.FeatureFlags JSON schema. Amazon AppConfig additionally validates that each feature flag attribute in your data satisfies the constraints you defined for those attributes.
