Auf dieser Seite wird beschrieben, wie Sie Ihr Air-Gap-Gerät für Google Distributed Cloud (GDC) aktualisieren und patchen.
Vorbereitung auf das Upgrade
Prüfen Sie vor dem Upgrade, ob Sie die in diesem Abschnitt aufgeführten Anforderungen erfüllen.
Hinweise
Prüfen Sie die Laptop-Voraussetzungen, um sicherzustellen, dass der Laptop, den Sie für das Update und die Patch-Upgrades verwenden, die physischen Spezifikationen und anderen Anforderungen erfüllt.
Sie müssen zuerst die folgenden Aktionen in Bezug auf die gdcloud-Befehlszeilentools (CLI) ausführen:
Kopieren Sie das Update mit Ihrem USB-Laufwerk in die Air-Gap-Umgebung.
Kopieren Sie sowohl das Downloader-Skript als auch das in Schritt 1 auf Ihren USB-Stick heruntergeladene Verzeichnis gdch auf den Computer für das Upgrade in der Air-Gap-Umgebung.
Prüfen Sie auf dem Upgrade-Computer den Inhalt und extrahieren Sie die Dateien mit denselben Informationen, die Sie zum Herunterladen des Pakets verwendet haben. Mit dem folgenden Code wird das Paket beispielsweise in das Verzeichnis /root kopiert.
Informationen zum Authentifizieren mit Ihrem konfigurierten Identitätsanbieter und zum Anfordern einer kubeconfig-Datei für Ihre Nutzeridentität und Ihren Cluster finden Sie unter Authentifizieren.

[Download](/distributed-cloud/hosted/docs/latest/appliance/resources/gdcloud-download) the `gdcloud` CLI tools.\n2. [Install](/distributed-cloud/hosted/docs/latest/appliance/resources/gdcloud-install) the `gdcloud` CLI tools.\n3. [Upgrade](/distributed-cloud/hosted/docs/latest/appliance/resources/gdcloud-upgrade) the `gdcloud` CLI tools as required.\n4. Ensure the [`docker-credential-gdcloud`](/distributed-cloud/hosted/docs/latest/appliance/infrastructure/io-operations-30/push-container-image#before-you-begin) is present.\n\n### Transfer the artifacts to the upgrade machine\n\nYou must have access to the Cloud Storage bucket.\n\nFollow these steps to transfer the artifacts to the laptop you use for the update and patch upgrades:\n\n1. Download the package based on the selected patch version:\n\n VERSION=\u003cx.x.x-gdch.yyy\u003e\n RELEASE_SUFFIX=\"_te\"\n DOWNLOADER=gdch-downloader-prod${RELEASE_SUFFIX}-$VERSION.sh\n gcloud storage cp \"gs://$GCS_BUCKET/$VERSION/$DOWNLOADER\" .\n gcloud storage cp \"gs://$GCS_BUCKET/$VERSION/${DOWNLOADER}.sig\" .\n\n PUBLIC_KEY=$(cat \u003c\u003c-PUBEND\n -----BEGIN PUBLIC KEY-----\n MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAEn46iVSyFXsvuKLZ4dVOr2AqlXDnR\n 5cKztkpraexHDxn/ozq03EvrdkRmZkSACFfcaEFyitpraidgAx8sPjvzXQ==\n -----END PUBLIC KEY-----\n PUBEND\n )\n echo \"${PUBLIC_KEY}\" \u003e \"key.pub\"\n DOWNLOADER=gdch-downloader-${PRODUCT}-$VERSION.sh\n\n gcloud storage cp \"gs://${GCS_BUCKET:-private-cloud-release}/$VERSION/$DOWNLOADER*\" .\n openssl dgst -sha256 -verify \"key.pub\" -signature \"${DOWNLOADER}.sig\" ${DOWNLOADER} && chmod +x $DOWNLOADER && ./$DOWNLOADER --skip-unzip\n\n This command fetches the update package and the downloader script to the current directory, for example, `/home/download`.\n2. Run `tree -L 3 /home/download`.\n\n Example output: \n\n /home/download\n ├── gdch\n │ └── x.x.x-gdch.x\n │ ├── bootstrapper\n │ │ ├── bootstrapper.iso\n │ │ └── bootstrapper.iso.sig\n │ ├── gdch-prod_te-x.x.x-gdch.x-sbom.tar.gz\n │ ├── gdch-prod_te-x.x.x-gdch.x-sbom.tar.gz.sig\n │ ├── prod_te_gdch.tar.gz\n │ └── prod_te_gdch.tar.gz.sig\n ├── gdch-downloader-prod_te-x.x.x-gdch.x.sh\n ├── gdch-downloader-prod_te-x.x.x-gdch.x.sh.1.sig\n ├── gdch-downloader-prod_te-x.x.x-gdch.x.sh.sig\n └── key.pub\n\n3. Copy the update to the air-gapped environment, using your USB drive.\n\n Copy both the downloader script and the `gdch` directory that you downloaded to your USB drive in [step 1](#download-pkg-step) to the upgrade machine in the air-gapped environment.\n4. In the upgrade machine, verify the contents and extract the files using the same information you used to download the package. For example, the following code copies the package to the `/root` directory.\n\n Unpack the package: \n\n VERSION=x.x.x-gdch.x\n PRODUCT=prod_te\n DOWNLOADER=gdch-downloader-${PRODUCT}-$VERSION.sh\n openssl dgst -sha256 -verify \"key.pub\" -signature \"${DOWNLOADER}.sig\" ${DOWNLOADER} && chmod +x $DOWNLOADER && ./$DOWNLOADER --skip-download\n\n The package is unpacked at the `/root/gdch/full-release-x.x.x-gdch.x` path.\n5. Confirm that the version matches the one that you set in VERSION:\n\n /root/gdch/full-release-x.x.x-gdch.x/gdcloud version\n\n Sample output: \n\n gdcloud version: 1.14.4-gdch.0\n\n | **Note:** From here on, all CLI commands must use the gdcloud binary from the recently downloaded artifacts.\n\nAuthenticate\n------------\n\nTo authenticate with your configured identity provider and request a kubeconfig file for your user identity and cluster, see [Authenticate](/distributed-cloud/hosted/docs/latest/appliance/resources/gdcloud-auth).\n\n1. [Sign in](/distributed-cloud/hosted/docs/latest/appliance/platform/pa-user/iam/sign-in) and request the following [roles](/distributed-cloud/hosted/docs/latest/appliance/platform/pa-user/iam/set-up-role-bindings#gdcloud):\n\n - Upgrade Appliance Admin\n - System Artifact Management Admin\n - System Artifact Management Secrets Admin\n - DNS Suffix Viewer\n - System Artifact Registry Monitor\n2. Configure the docker:\n\n gdcloud auth configure-docker\n\nStart the upgrade\n-----------------\n\nGo through the following steps to start the appliance upgrade: \n\n gdcloud appliance upgrade \n\nSee [`gdcloud appliance upgrade`](/distributed-cloud/hosted/docs/latest/appliance/resources/gdcloud-reference/gdcloud-appliance-upgrade) for more information.\n\nThe command runs the following steps:\n\n1. Runs the preflight checks on the upgrade machine.\n2. Runs the preflight checks for OTS storage\n3. Pushes the artifacts to the artifact registry.\n4. Upgrades the appliance software and firmware, including:\n 1. GDC root-admin cluster.\n 2. GDC services.\n 3. The operating systems (OSes) of physical and virtual nodes.\n 4. The switch.\n 5. Storage\n\nThe command drives the updates in sequence, and waits for each step to complete. After completing the steps and if the upgrade is successful, you see a message similar to the following: \n\n The GDC appliance upgrade completed successfully"]]
