Example 1 with AppInfoImpl

use of com.nike.riposte.server.config.impl.AppInfoImpl in project riposte by Nike-Inc.

the class AwsUtil method getAppInfoFutureWithAwsInfo.

/**
 * @param appId The app ID for the running application.
 * @param environment The environment the application is running in (local, test, prod, etc).
 * @param asyncHttpClientHelper The async HTTP client you want this method to use to make the AWS metadata calls.
 *
 * @return A {@link CompletableFuture} that will eventually yield an {@link AppInfo} with the values coming from the
 * given arguments for app ID and environment, and coming from the AWS metadata services for datacenter and instance
 * ID. If the given environment is "local" then {@link AppInfoImpl#createLocalInstance(String)} will be returned
 * (see the javadocs of that method for more information on what values it will contain). Otherwise the AWS metadata
 * services will be used to determine {@link AppInfo#dataCenter()} and {@link AppInfo#instanceId()}. If those AWS
 * metadata calls fail for any reason then {@link AppInfo#UNKNOWN_VALUE} will be used instead.
