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.
Menjalankan aplikasi yang penting bagi bisnis di Cloud Composer memerlukan banyak pihak untuk mengemban tanggung jawab yang berbeda-beda. Meskipun bukan daftar lengkap, dokumen ini mencantumkan tanggung jawab bagi Google dan Pelanggan.
Tanggung Jawab Google
Memperkuat dan
mem-patch komponen lingkungan Cloud Composer dan infrastruktur yang mendasarinya, termasuk
cluster Google Kubernetes Engine, database Cloud SQL (yang menghosting database
Airflow), Pub/Sub, Artifact Registry, dan elemen lingkungan
lainnya. Secara khusus, hal ini mencakup upgrade otomatis infrastruktur dasar, termasuk cluster GKE dan instance Cloud SQL dari suatu lingkungan.
Menyediakan integrasi Google Cloud untuk Identity and Access Management, Cloud Audit Logs, dan Cloud Key Management Service.
Membatasi dan mencatat akses administratif Google ke cluster pelanggan untuk tujuan dukungan kontrak dengan Transparansi Akses dan Persetujuan Akses.
Memublikasikan informasi tentang perubahan yang tidak kompatibel dengan versi sebelumnya antara
versi Cloud Composer dan Airflow di
Catatan Rilis Cloud Composer.
Memperbarui dokumentasi Cloud Composer:
Memberikan deskripsi semua fungsi yang disediakan oleh
Cloud Composer.
Memberikan petunjuk pemecahan masalah yang membantu menjaga lingkungan dalam
kondisi yang baik.
Memublikasikan informasi tentang masalah umum beserta solusinya (jika ada).
Menyelesaikan insiden keamanan penting yang terkait dengan lingkungan Cloud Composer dan image Airflow yang disediakan oleh Cloud Composer (tidak termasuk paket Python yang diinstal pelanggan) dengan mengirimkan versi lingkungan baru yang mengatasi insiden tersebut.
Bergantung pada Paket Dukungan pelanggan, pemecahan masalah
masalah kesehatan lingkungan Cloud Composer.
Bekerja sama dengan komunitas Apache Airflow untuk memelihara dan mengembangkan
operator Google Airflow.
Memecahkan masalah dan, jika memungkinkan, memperbaiki masalah dalam fungsi
inti Airflow.
Tanggung jawab pelanggan
Mengupgrade ke versi Cloud Composer dan Airflow baru untuk mempertahankan
dukungan produk dan menyelesaikan masalah keamanan setelah
layanan Cloud Composer memublikasikan versi Cloud Composer
yang mengatasi masalah tersebut.
Mempertahankan kode DAG agar tetap kompatibel dengan versi Airflow yang digunakan.
Memastikan konfigurasi cluster GKE lingkungan tetap utuh,
terutama termasuk fitur upgrade otomatisnya.
Mempertahankan izin yang sesuai di IAM untuk akun layanan
lingkungan. Secara khusus, mempertahankan izin yang diperlukan oleh Agen Cloud Composer dan akun layanan lingkungan. Mempertahankan
izin yang diperlukan untuk kunci CMEK yang digunakan untuk enkripsi lingkungan
Cloud Composer dan merotasi kunci tersebut sesuai kebutuhan Anda.
Mempertahankan izin yang tepat di IAM untuk bucket
lingkungan
dan repositori Artifact Registry tempat image komponen Cloud Composer disimpan
.
Mempertahankan izin IAM yang sesuai untuk akun layanan
yang melakukan penginstalan paket PyPI. Untuk informasi selengkapnya, lihat
Kontrol akses.
Mempertahankan izin pengguna akhir yang sesuai dalam konfigurasi IAM dan Kontrol Akses UI Airflow.
Menjaga ukuran database Airflow di bawah
16 GB dengan
menggunakan DAG pemeliharaan.
Menyelesaikan semua masalah penguraian DAG sebelum mengajukan kasus dukungan ke
Layanan Pelanggan Cloud.
Memberi nama DAG dengan cara yang tepat (misalnya, tanpa menggunakan karakter yang tidak terlihat
seperti SPASI atau TAB dalam nama DAG) sehingga metrik dapat dilaporkan dengan benar
untuk DAG.
Upgrade kode DAG agar tidak menggunakan operator yang tidak digunakan lagi dan
bermigrasi ke alternatif terbarunya. Operator yang tidak digunakan lagi mungkin
dihapus dari penyedia Airflow, yang dapat memengaruhi rencana Anda untuk mengupgrade
ke versi Cloud Composer atau Airflow yang lebih baru. Operator yang tidak digunakan lagi juga tidak dipertahankan dan harus digunakan 'apa adanya'.
Mengonfigurasi izin IAM yang sesuai saat menggunakan backend secret seperti Secret Manager sehingga akun layanan lingkungan memiliki akses ke akun tersebut.
Menyesuaikan parameter lingkungan Cloud Composer (seperti CPU dan
memori untuk komponen Airflow) dan konfigurasi Airflow untuk memenuhi
performa dan ekspektasi beban lingkungan Cloud Composer
menggunakan
panduan pengoptimalan Cloud Composer
dan panduan penskalaan lingkungan.
Menghindari penghapusan izin yang diperlukan oleh Agen Cloud Composer dan akun layanan lingkungan (menghapus izin ini dapat menyebabkan operasi pengelolaan gagal atau kegagalan DAG dan tugas).
Menghindari penginstalan atau pengoperasian komponen tambahan di cluster GKE lingkungan yang mengganggu komponen Cloud Composer dan mencegahnya berfungsi dengan benar.

While not an exhaustive\nlist, this document lists the responsibilities for both Google and the Customer\nsides.\n\nGoogle Responsibilities\n-----------------------\n\n- [Hardening](/container-optimized-os/docs/concepts/security) and\n [patching](/kubernetes-engine/docs/resources/security-patching) the Cloud Composer\n environment's components and underlying infrastructure, including\n Google Kubernetes Engine cluster, Cloud SQL database (that hosts the Airflow\n database), Pub/Sub, Artifact Registry and other environment\n elements. In particular, this includes auto-upgrading the underlying\n infrastructure, including the GKE cluster and\n Cloud SQL instance of an environment.\n\n | **Note:** Cloud Composer 1 is in the post-maintenance mode and new versions of Cloud Composer 1 with security fixes are no longer published. Migrate to Cloud Composer 2 to get the latest version updates with security improvements.\n- Protecting access to Cloud Composer environments through\n incorporating access control provided by IAM,\n [encrypting data at rest by default](/security/encryption-at-rest/default-encryption),\n providing [additional customer-managed storage encryption](/kubernetes-engine/docs/how-to/using-cmek),\n [encrypting data in transit](/security/encryption-in-transit).\n\n- Providing Google Cloud integrations for Identity and Access Management, Cloud Audit Logs\n and Cloud Key Management Service.\n\n- Restricting and logging Google administrative access to customers' clusters\n for contractual support purposes with\n [Access Transparency](/access-transparency) and\n [Access Approval](/cloud-provider-access-management/access-approval/docs/overview).\n\n- Publishing information about backward incompatible changes between\n Cloud Composer and Airflow versions in\n [Cloud Composer Release Notes](/composer/docs/release-notes).\n\n- Keeping Cloud Composer documentation up to date:\n\n - Providing description of all functionalities provided by\n Cloud Composer.\n\n - Providing troubleshooting instructions that help to keep environments in\n a healthy state.\n\n - Publishing information about known issues with workarounds (if they\n exist).\n\n- Resolving critical security incidents related to Cloud Composer\n environments and Airflow images provided by Cloud Composer\n (excluding customer-installed Python packages) by delivering new\n environment versions addressing the incidents.\n\n- Depending on customer's Support Plan, troubleshooting of\n Cloud Composer environment health issues.\n\n- Maintaining and expanding the functionality of the\n [Cloud Composer Terraform provider](https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/composer_environment).\n\n- Cooperating with the Apache Airflow community to maintain and develop\n [Google Airflow operators](https://airflow.apache.org/docs/apache-airflow-providers-google/stable/operators/cloud/cloud_composer.html).\n\n | **Note:** Google won't fix or troubleshoot issues in operator providers for third-party services or products.\n- Troubleshooting and, if possible, fixing issues in Airflow core\n functionalities.\n\nCustomer responsibilities\n-------------------------\n\n- Upgrading to new Cloud Composer and Airflow versions to keep\n support for the product and to resolve security issues once\n Cloud Composer service publishes a Cloud Composer\n version that addresses the issues.\n\n- Maintaining the DAGs code to keep it compatible with the used Airflow version.\n\n- Keeping the environment's GKE cluster configuration intact,\n particularly including its auto-upgrade feature.\n\n- Maintaining proper permissions in IAM for the environment's\n service account. Particularly, keeping permissions required by the\n [Cloud Composer Agent](/composer/docs/composer-2/access-control#composer-sa) and the\n [environment's service account](/composer/docs/composer-2/access-control#service-account). Maintaining\n required permission for the CMEK key used for Cloud Composer\n environment encryption and rotating it according to your needs.\n\n | **Caution:** We recommend to [set up a user-managed service account](/composer/docs/composer-2/access-control#custom-service-account) for Cloud Composer environments that has only the required set of permissions that are necessary to run the environment and perform operations defined in your DAGs. The **Composer Worker** (`composer.worker`) role provides this required set of permissions in most cases. Add extra permissions to this service account only when it's necessary for the operation of your DAGs. \n |\n | Although we recommend against using this approach, if you don't specify an environment's service account, then your Cloud Composer environment uses the default Compute Engine service account. The default Compute Engine service account usually has the **Editor** basic role, which contains many more permissions than necessary to run Cloud Composer environments and thus creates a risk of DAGs using broader permissions than intended.\n- Maintaining proper permissions in IAM for the environment's\n bucket\n\n and Artifact Registry repository where Cloud Composer's component images are stored\n\n .\n\n | **Caution:** Users with read-write access to the following components:\n | - Your environment's bucket\n | - Artifact Registry repositories with container images used by: %Airflow components, `GKEPodOperator`, or `GKEStartPodOperator`\n |\n | can deploy their own versions of DAGs or container images to an environment\n | even without explicit Cloud Composer-related permissions.\n | These DAGs or images can be later executed in your environment\n | with the permissions of the Cloud Composer environment\n | service account.\n- Maintaining proper IAM permissions for a service account\n that performs PyPI packages installations. For more information, see\n [Access control](/composer/docs/composer-2/access-control#service-account-security).\n\n | **Caution:** Users with read-write access to the environment's bucket or those who can initiate PyPI packages installations can initate the process of building images on behalf of a service account which is used to perform such builds. This service account is called the environment's service account that is specified during the environment creation, It can be a user-provided service account, or the default service account.\n- Maintaining proper end user permissions in IAM and Airflow\n UI Access Control configuration.\n\n- Keeping Airflow database size below\n 16 GB through\n using the [maintenance DAG](/composer/docs/composer-2/cleanup-airflow-database).\n\n- Resolving all DAG parsing issues before raising support cases to\n Cloud Customer Care.\n\n- Naming DAGs in a proper way (for example, without using invisible characters\n like SPACE or TAB in DAG names) so that metrics can be reported correctly\n for DAGs.\n\n- Upgrade the code of DAGs so that it doesn't use deprecated operators and\n migrate to their up to date alternatives. Deprecated operators might be\n removed from Airflow providers, which might impact your plans to upgrade\n to a later Cloud Composer or Airflow version. The deprecated\n operators are also not maintained and they must be used 'as is'.\n\n- Configuring proper IAM permissions when using secret\n backends like Secret Manager so that the environment's\n service account has access to it.\n\n- Adjusting Cloud Composer environment parameters (such as CPU and\n memory for Airflow components) and Airflow configurations to meet\n performance and load expectations of Cloud Composer environments\n using\n [Cloud Composer optimization guide](/composer/docs/composer-2/optimize-environments)\n and [environment scaling guide](/composer/docs/composer-2/scale-environments).\n\n- Avoiding removing permissions required by Cloud Composer Agent and\n environment's service accounts (removing these permissions can lead either\n to failed management operations or to DAG and task failures).\n\n- Keeping\n [all services and APIs required by Cloud Composer](/composer/docs/composer-2/enable-composer-service#required-services)\n always enabled. These dependencies must have quotas configured at levels\n required for Cloud Composer.\n\n- Keeping Artifact Registry repositories that host container images used by\n Cloud Composer environments.\n\n- [Following recommendations and best practices](/composer/docs/composer-2/write-dags) for\n implementing DAGs.\n\n- Diagnosing DAG and task failures using instructions for\n [scheduler troubleshooting](/composer/docs/composer-2/troubleshooting-scheduling),\n [DAG troubleshooting](/composer/docs/composer-2/troubleshooting-dags) and\n [triggerer troubleshooting](/composer/docs/composer-2/troubleshooting-triggerer).\n\n- Avoiding installing or running additional components in the environment's\n GKE cluster that interfere with Cloud Composer\n components and prevent them from functioning correctly.\n\nWhat's next\n-----------\n\n- [Access control with IAM](/composer/docs/composer-2/access-control)\n- [Clean up the Airflow database](/composer/docs/composer-2/cleanup-airflow-database)\n- [Security overview](/composer/docs/composer-2/composer-security-overview)"]]
