Subnet dual-stack memungkinkan layanan dan tugas Cloud Run Anda mengirim traffic IPv4 dan IPv6 internal ke jaringan VPC dengan traffic keluar VPC Langsung.
Anda dapat mengubah jenis stack layanan atau tugas Cloud Run yang ada atau
mengupdate subnet yang ada ke subnet stack ganda.
Dukungan stack ganda hanya tersedia dengan subnet di jaringan VPC mode kustom. Agar jenis akses internal tersedia untuk subnet stack ganda, rentang IPv6 internal jaringan VPC harus diaktifkan. Siapkan atau konversi
jaringan VPC ke mode kustom.
Dibandingkan dengan subnet khusus IPv4, subnet dual-stack mungkin mengalami latensi cold-start yang lebih tinggi, sehingga membatasi seberapa cepat aplikasi Anda dapat melakukan penskalaan.
Menambahkan subnet stack ganda pada layanan atau tugas
Subnet stack ganda memiliki rentang alamat IPv4 dan IPv6. Layanan dan tugas Cloud Run hanya dapat mengirim traffic IPv6 melalui subnet yang menggunakan alamat IPv6 internal.
Untuk menambahkan subnet stack ganda dengan rentang IPv6 internal pada layanan atau tugas Cloud Run, lakukan hal berikut:
Klik Create VPC network jika Anda membuat jaringan mode kustom baru.
Jika Anda menggunakan jaringan VPC yang sudah ada, klik nama jaringan VPC untuk menampilkan halaman VPC network details-nya.
Jika Anda membuat jaringan baru atau mengonversi jaringan yang sudah ada, masukkan nama dan pastikan Subnet creation mode disetel ke Custom, lalu pilih Configure a ULA internal IPv6 range for this VPC Network.
Dari tab Subnets, klik Add subnet. Pada panel yang muncul:
Berikan Nama.
Pilih Region.
Untuk IP stack type, pilih IPv4 and IPv6 (dual-stack).
Jika opsi Internal tidak tersedia, periksa apakah rentang IPv6 internal telah ditetapkan di jaringan.
Klik Done, lalu klik Create.
Deploy layanan Cloud Run atau
jalankan tugas di subnet stack ganda
yang Anda buat. Saat memasukkan detail layanan atau tugas yang diperlukan, Anda
dapat memilih rentang alamat IPv6 baru dengan mengikuti langkah-langkah berikut:
Klik Container(s), Volumes, Networking, Security, lalu pilih tab Networking.
Klik Hubungkan ke VPC untuk traffic keluar, lalu Kirim traffic
langsung ke VPC.
Pilih Network yang Anda buat pada langkah sebelumnya.
Klik kolom Subnet untuk memilih rentang alamat IPv6 yang baru dibuat.
Layanan atau tugas otomatis disediakan
dengan jenis stack subnet.
gcloud
Untuk membuat jaringan mode kustom yang mendukung subnet stack ganda, jalankan perintah berikut:
Mengubah subnet dari stack ganda menjadi stack tunggal
Mengubah jenis stack subnet dari IPv4 dan IPv6 (stack ganda) menjadi hanya IPv4 (stack tunggal) tidak didukung karena jenis akses IPv6 Compute Engine adalah internal. Untuk mengubah subnet stack ganda layanan atau tugas menjadi subnet
stack tunggal, deploy layanan atau
jalankan tugas di subnet
khusus IPv4 (stack tunggal).
Verifikasi jaringan dan subnet
Untuk memeriksa apakah layanan atau tugas Anda berada di jaringan VPC, jalankan
perintah berikut:

Learn more about\n [internal and external access types for IPv6 addresses](/vpc/docs/subnets#ipv6-ranges).\n\n- Dual-stack support is only available with subnets in a custom-mode\n VPC network. To have the internal access type\n available for dual-stack subnets, the VPC network internal IPv6\n range must be enabled. Set up or [convert](/vpc/docs/create-modify-vpc-networks#switch-network-mode)\n the VPC network to custom mode.\n\n- Compared to IPv4-only subnets, dual-stack subnets might experience elevated\n cold-start latencies, limiting how quickly your application can scale up.\n\n- [NAT64](https://tools.ietf.org/html/rfc6146) is not supported.\n\nAdd a dual-stack subnet on a service or job\n-------------------------------------------\n\nDual-stack subnets have both IPv4 and IPv6 address ranges. Cloud Run\nservices and jobs can only send IPv6 traffic through a subnet that uses\n[internal IPv6 addresses](/vpc/docs/subnets#ipv6-ranges).\n\nTo add a dual-stack subnet with an internal IPv6 range on a Cloud Run\nservice or job, do the following: \n\n### Console\n\n1. In the Google Cloud console:\n\n 1. Enable the Compute Engine API:\n\n [Enable the Compute Engine API](https://console.cloud.google.com/apis/library/compute.googleapis.com)\n 2. Go to the **VPC networks** page:\n\n [Go to VPC networks](https://console.cloud.google.com/networking/networks/list)\n2. Click **Create VPC network** if you are creating a new custom-mode network.\n If you are using an existing VPC network, click the name of the\n VPC network to show its *VPC network details* page.\n\n3. If you are creating a new network or converting an existing one, enter the\n name and be sure that the **Subnet creation mode** is set to **Custom** , then select\n **Configure a ULA internal IPv6 range for this VPC Network**.\n\n4. From the **Subnets** tab, click **Add subnet**. In the panel that appears:\n\n 1. Provide a **Name**.\n 2. Select a **Region**.\n 3. For **IP stack type** , select **IPv4 and IPv6 (dual-stack)**.\n 4. Enter an **IPv4 range** . This is the [primary IPv4 range](/vpc/docs/vpc#vpc_networks_and_subnets) for the subnet.\n 5. Select **Internal** for the **IPv6 access type**.\n\n If the **Internal** option is not available, check that an internal\n IPv6 range is assigned on the network.\n 6. Click **Done** , then click **Create**.\n\n5. [Deploy a Cloud Run service](/run/docs/deploying) or\n [execute a job](/run/docs/execute/jobs#execute_jobs) on the dual-stack\n subnet that you created. As you enter the needed service or job details, you\n can select the new IPv6 address range by following these steps:\n\n 1. Click **Container(s), Volumes, Networking, Security** and select the **Networking** tab.\n 2. Click **Connect to a VPC for outbound traffic** and then **Send traffic\n directly to a VPC**.\n 3. Select the **Network** that you created in the previous step.\n 4. Click the **Subnet** field to select the newly created IPv6 address range.\n\n The service or job is automatically provisioned\n with the subnet's stack type.\n\n### gcloud\n\n1.

To create a dual-stack subnet with an internal IPv6 range, run the [`subnets create` command](/sdk/gcloud/reference/compute/networks/subnets/create) using the dual-stack settings:\n\n```\ngcloud compute networks subnets create SUBNET \\\n --network=NETWORK \\\n --range=PRIMARY_IPv4_RANGE \\\n --stack-type=IPV4_IPV6 \\\n --ipv6-access-type=INTERNAL \\\n --region=REGION\n```\n\nReplace the following:\n\n- \u003cvar translate=\"no\"\u003eSUBNET\u003c/var\u003e: a name for the new subnet.\n- \u003cvar translate=\"no\"\u003eNETWORK\u003c/var\u003e: the name of the VPC network that will contain the new subnet.\n- \u003cvar translate=\"no\"\u003ePRIMARY_IPv4_RANGE\u003c/var\u003e: the primary IPv4 range for the new subnet, in CIDR notation.
