Pada 15 September 2026, semua lingkungan Cloud Composer 1 dan Cloud Composer 2 versi 2.0.x akan mencapai akhir masa pakainya yang direncanakan, dan Anda tidak akan dapat menggunakannya. Sebaiknya rencanakan migrasi ke Cloud Composer 3.
Halaman ini menjelaskan persyaratan project host dan jaringan VPC Bersama untuk Cloud Composer.
VPC Bersama memungkinkan organisasi menetapkan batas kontrol akses dan anggaran di tingkat project sekaligus memungkinkan komunikasi yang aman dan efisien menggunakan IP pribadi di seluruh batas tersebut.
Dalam konfigurasi VPC Bersama, Cloud Composer dapat memanggil layanan yang dihosting di project lain dalam organisasi yang sama tanpa mengekspos layanan ke internet publik. Google Cloud
Pedoman untuk VPC Bersama
Gambar 1. Project layanan dan host untuk
Cloud Composer 3 (klik untuk memperbesar)
VPC Bersama mengharuskan Anda menetapkan project host yang memiliki jaringan dan sub-jaringan, serta project layanan, yang dilampirkan ke project host.
Saat Cloud Composer berpartisipasi dalam VPC Bersama, lingkungan Cloud Composer berada di project layanan.
Pastikan rentang IP internal lingkungan Cloud Composer dan rentang jaringan VPC Anda tidak memiliki konflik.
Saat melampirkan project, biarkan izin Jaringan VPC default tetap ada.
Memberikan izin ke akun Agen Layanan Composer
Di project host:
Edit izin untuk akun Agen Layanan Composer,
service-SERVICE_PROJECT_NUMBER@cloudcomposer-accounts.iam.gserviceaccount.com)
Tambahkan peran lain, Composer Shared VPC Agent (composer.sharedVpcAgent).
di tingkat project.
Kesimpulan
Anda telah menyelesaikan konfigurasi jaringan VPC Bersama untuk project layanan dan host.
Sekarang Anda dapat menghubungkan lingkungan baru dan yang sudah ada di project layanan ke jaringan VPC project host. Anda dapat menggunakan salah satu pendekatan berikut:
Hubungkan lingkungan ke jaringan VPC Bersama. Cloud Composer
membuat lampiran jaringan baru untuk lingkungan.
Buat lampiran jaringan di project layanan, hubungkan ke jaringan VPC Bersama, dan hubungkan satu atau beberapa lingkungan ke lampiran jaringan ini.

[Find the following project IDs and project numbers](/kubernetes-engine/docs/how-to/cluster-shared-vpc#finding_your_project_ids_and_numbers):\n\n - Host project: The project that contains the Shared VPC network.\n - Service project: The project that contains the Cloud Composer environment.\n2. [Prepare your organization](/vpc/docs/provisioning-shared-vpc#prepare_your_organization).\n\nConfigure the service project\n-----------------------------\n\nIf Cloud Composer environments were never created in the service\nproject, then provision the Composer Service Agent Account\n**in the service project**: \n\n gcloud beta services identity create --service=composer.googleapis.com\n\nConfigure the host project\n--------------------------\n\nConfigure the host project as described further.\n| **Caution:** Do all of the described actions **in the host project**. For example, if you add roles to a service account from the service project, assign them in the host project's IAM configuration.\n\n### Configure networking resources\n\nChoose one of the following options:\n\n- Option 1.\n [Create a new VPC network and a subnet](/vpc/docs/create-modify-vpc-networks#create-custom-network).\n\n- Option 2.\n [Create a subnet in an existing VPC network](/vpc/docs/create-modify-vpc-networks#add-subnets).\n\n- Option 3. Use an existing VPC network and a subnet.\n\n\n### Set up Shared VPC and attach the service project\n\n1. If not already done, [Set up Shared VPC](/vpc/docs/provisioning-shared-vpc#enable-shared-vpc-host). If\n you already have set up Shared VPC, skip to the next step.\n\n2. [Attach the service project](/vpc/docs/provisioning-shared-vpc#create-shared), which you\n use to host Cloud Composer environments.\n\n When attaching a project, leave the default VPC Network permissions\n in place.\n\n### Grant permissions to the Composer Service Agent account\n\n| **Warning:** On this and next steps, when editing permissions, keep the existing account roles. Add another role to an account instead of replacing an existing role.\n\nIn the host project:\n\n1. Edit permissions for the Composer Service Agent account,\n `service-`\u003cvar translate=\"no\"\u003eSERVICE_PROJECT_NUMBER\u003c/var\u003e`@cloudcomposer-accounts.iam.gserviceaccount.com`)\n\n2. Add another role, **Composer Shared VPC Agent** (`composer.sharedVpcAgent`).\n at the project level.\n\n \u003cbr /\u003e\n\nConclusion\n----------\n\nYou've completed the Shared VPC network configuration for both service and host\nprojects.\n\nNow you can connect new and existing environments in the service project to the\nhost project's VPC network. You can use one of the following approaches:\n\n- Connect an environment to a Shared VPC network. Cloud Composer creates a new network attachment for the environment.\n- Create a network attachment in the service project, connect it to a Shared VPC network, and connect one or more environments to this network attachment.\n\nFor instructions and more information about differences between the two\ndescribed approaches, see\n[Connect a VPC network to your environment](/composer/docs/composer-3/connect-vpc-network).\n\n\nWhat's next\n-----------\n\n- [Connect a VPC network to your environment](/composer/docs/composer-3/connect-vpc-network).\n- [Create a Cloud Composer environment](/composer/docs/composer-3/create-environments)."]]
