In diesem Abschnitt wird der Synchronizer beschrieben.
Synchronizer – Übersicht
In Apigee Hybrid besteht die Hauptaufgabe des Synchronizers darin, die von der Verwaltungsebene bereitgestellten Laufzeitverträge abzurufen und herunterzuladen. Zu den im Vertrag enthaltenen Informationen gehören API-Proxys, API-Produkte, Caches und virtuelle Hosts. Synchronizer speichert standardmäßig Umgebungskonfigurationsdaten in der Cassandra-Datenbank.
Synchronizer-Instanzen, die in der Laufzeitebene ausgeführt werden, sollten regelmäßig die Verwaltungsebene abfragen, die Verträge herunterladen und diese den lokalen Laufzeitinstanzen zur Verfügung stellen.
Ein Synchronizer unterstützt viele Nachrichtenverarbeiter, die im gleichen Pod bereitgestellt sind.
Synchronizer-Zugriff aktivieren
Sie müssen die Berechtigung Synchronizer erteilen, um Apigee-Artefakte wie Proxy-Bundles und Ressourcen von der Verwaltungsebene abzurufen. Sie müssen eine Apigee API aufrufen, um den Synchronizer zu autorisieren, Artefakte von der Verwaltungsebene zur Laufzeitebene abzurufen.
Prüfen Sie, ob die Apigee API wie in den Google Cloud-Einrichtungsschritten beschrieben aktiviert wurde.
Weitere Informationen finden Sie unter Schritt 3: APIs aktivieren.
Suchen Sie nach dem schreibberechtigten Google Cloud-Dienstkontoschlüssel (eine JSON-Datei), den Sie im Abschnitt Dienstkonten erstellen heruntergeladen haben. Das Dienstkonto hat die Rolle Apigee-Organisationsadministrator und den Namen "apigee-org-admin". Wenn Sie dieses Dienstkonto nicht zuvor erstellt haben, müssen Sie dies tun, bevor Sie fortfahren.
Legen Sie die Umgebungsvariable GOOGLE_APPLICATION_CREDENTIALS auf den Pfad fest, in dem sich der Dienstkontoschlüssel befindet:
your_org_name ist der Name der Hybridorganisation.
synchronizer-manager-service-account-name ist der Name eines Dienstkontos mit der Rolle Apigee Synchronizer Manager. Der Name sieht wie eine E-Mail-Adresse aus. Beispiel: my-synchronizer-manager-service_account@my_project_id.iam.gserviceaccount.com

For more information, see [Supported versions](/apigee/docs/hybrid/supported-platforms#supported-versions).\n\nThis section describes the Synchronizer.\n\nSynchronizer overview\n---------------------\n\nIn Apigee hybrid, the Synchronizer's primary job is to poll and download the runtime contracts\nwhich are supplied by the management plane. Information communicated by contract includes API\nproxies, API products, caches, and virtual hosts. Synchronizer by default stores environment\nconfiguration data in the Cassandra database.\n\nSynchronizer instances running in the runtime-plane are expected to poll the management\nplane on a regular basis, download the contracts and make the same available to local runtime\ninstances.\n\nOne Synchronizer can support many Message Processors deployed in the same pod.\n\nEnable Synchronizer access\n--------------------------\n\nYou must grant the [Synchronizer](/apigee/docs/hybrid/v1.6/what-is-hybrid#synchronizer) permission to pull down\nApigee artifacts, such as proxy bundles and resources from the management plane. You must call an\nApigee API to authorize the Synchronizer to pull artifacts down from the management plane to the\nruntime plane.\n\n1. Ensure that you have enabled the Apigee API as explained in the Google Cloud setup steps. For details, see [Step 3: Enable APIs](/apigee/docs/hybrid/v1.6/precog-enableapi).\n2. Locate the **write-enabled Google Cloud service account key** (a JSON file) that you downloaded as part of [Create service accounts](/apigee/docs/hybrid/v1.6/install-download-install#create-service-accounts). The service account has the **Apigee Org Admin** role and is the one named \"apigee-org-admin\". If you did not previously create this service account, you must do so before continuing.\n3. Set the `GOOGLE_APPLICATION_CREDENTIALS` environment variable to the path where the\n service account key is located:\n\n export GOOGLE_APPLICATION_CREDENTIALS=\u003cvar translate=\"no\"\u003eyour_sa_credentials_file\u003c/var\u003e.json\n\n 4. Call the [setSyncAuthorization](/apigee/docs/hybrid/v1.6/syncauthorization-reference) API to enable the required permissions for Synchronizer: **IMPORTANT:** Be sure that the service account name that you add to this API has the role **Apigee Synchronizer Manager** . See also [Create service accounts](/apigee/docs/hybrid/v1.6/install-download-install#create-service-accounts). \n\n ```\n curl -X POST -H \"Authorization: Bearer $(gcloud auth application-default print-access-token)\" \\\n -H \"Content-Type:application/json\" \\\n \"https://apigee.googleapis.com/v1/organizations/your_org_name:setSyncAuthorization\" \\\n -d '{\"identities\":[\"serviceAccount:synchronizer-manager-service-account-name\"]}'\n ```\n\n Where:\n - `your_org_name`: The name of the hybrid organization.\n - `synchronizer-manager-service-account-name`: The name of a service account with the **Apigee Synchronizer Manager** role. The name is formed like an email address. For example: `my-synchronizer-manager-service_account@my_project_id.iam.gserviceaccount.com`\n\n Example: \n\n ```\n curl -X POST -H \"Authorization: Bearer $(gcloud auth application-default print-access-token)\" \\\n -H \"Content-Type:application/json\" \\\n \"https://apigee.googleapis.com/v1/organizations/my_org:setSyncAuthorization\" \\\n -d '{\"identities\":[\"serviceAccount:my-synchronizer-manager-service_account@my_project_id.iam.gserviceaccount.com\"]}'\n ```\n\n For more information on this API, see [SyncAuthorization\n API](/apigee/docs/hybrid/v1.6/syncauthorization-reference).\n5. To verify that the service account was set, call the following API to get a list of service accounts: \n\n ```\n curl -X POST -H \"Authorization: Bearer $(gcloud auth application-default print-access-token)\" \\\n -H \"Content-Type:application/json\" \\\n \"https://apigee.googleapis.com/v1/organizations/your_org_name:getSyncAuthorization\" \\\n -d ''\n ```\n\n The output looks similar to the following: \n\n ```transact-sql\n {\n \"identities\":[\n \"serviceAccount:my-synchronizer-manager-service_account@my_project_id.iam.gserviceaccount.com\"\n ],\n \"etag\":\"BwWJgyS8I4w=\"\n }\n ```"]]
