Langkah 6: Konfigurasi cluster

Menentukan penggantian konfigurasi

Penginstal hybrid Apigee menggunakan setelan default untuk banyak setelan; Namun, ada adalah beberapa pengaturan yang tidak memiliki {i>default<i}. Anda harus memberikan nilai untuk pengaturan ini, seperti yang dijelaskan selanjutnya.

Sebelum memulai

Sebaiknya tinjau skenario berikut untuk menentukan apakah Anda ingin mengonfigurasi cluster untuk mereka. Konfigurasi ini bersifat opsional.

• Jika Anda berencana menginstal hybrid di beberapa region, baca Deployment multi-region sebelum melanjutkan.
• Apigee Hybrid menyediakan sandi default untuk pengguna Cassandra; namun, sebaiknya Anda mengubah {i> password<i} pengguna secara {i>default<i}. Lihat Mengonfigurasi TLS untuk Cassandra guna mengetahui detailnya.
• Jika Anda ingin mengonfigurasi setelan penyimpanan dan heap untuk Cassandra, lihat Mengonfigurasi setelan penyimpanan dan heap.
• Untuk skenario penginstalan produksi, konfigurasi penyimpanan persisttent solid state disk (SSD) untuk Cassandra. Kami tidak mendukung penggunaan SSD lokal untuk Apigee Hybrid. Sebagai detail, lihat Menambahkan penyimpanan SSD untuk deployment produksi.

Mengonfigurasi cluster

Berdasarkan konvensi, penggantian konfigurasi ditulis dalam file bernama overrides.yaml di direktori $HYBRID_FILES/overrides Anda.

1. Buat file baru bernama overrides.yaml di Direktori $HYBRID_FILES/overrides. Contoh:

   vi $HYBRID_FILES/overrides/overrides.yaml

   overrides.yaml menyediakan konfigurasi untuk instalasi Apigee Hybrid yang unik. File yang diganti di langkah ini menyediakan konfigurasi dasar untuk hibrida jejak kecil instalasi {i>runtime<i}, yang cocok untuk instalasi pertama Anda.

2. Di overrides.yaml, tambahkan properti yang diperlukan nilai tersebut, seperti yang ditampilkan di bawah ini. Deskripsi mendetail tentang setiap properti juga tersedia di bawah.

   Jika Anda menginstal Apigee Hybrid di GKE dan berencana menggunakan Workload identity untuk mengautentikasi komponen hybrid, pilih tab GKE - Workload identity File overrides.yaml.

   Untuk semua penginstalan lainnya, pilih tab untuk non-produksi, Non-prod, atau lingkungan production, Prod, bergantung pada pilihan Anda Langkah 4: Buat akun layanan dan kredensial.

   Untuk penginstalan di lingkungan produksi, lihat persyaratan penyimpanan untuk Database Cassandra di Mengonfigurasi Cassandra untuk produksi.

   GKE - Workload Identity

   Pastikan file overrides.yaml memiliki mengikuti struktur dan {i>syntax<i}. Nilai dalam red, bold italics adalah nilai properti yang harus Anda berikan. Hal tersebut dijelaskan dalam tabel di bawah ini.

   Jika menginstal Apigee Hybrid di GKE, Anda memiliki alternatif untuk melakukan autentikasi dan membuat permintaan ke Google API, Workload Identity. Untuk ringkasan Workload Identitas, lihat:

   • Memperkenalkan Workload Identity: Autentikasi yang lebih baik untuk aplikasi GKE Anda
   • Menggunakan Workload Identity

   Untuk menggunakan Workload Identity dengan Apigee Hybrid di GKE, gunakan template ini, lalu ikuti langkah-langkah di Langkah 8: Instal runtime hybrid untuk membuat akun layanan Kubernetes dan mengaitkannya dengan akun layanan Google yang yang dibuat di Langkah 4: Buat akun layanan dan mereka.

Ringkasan

File konfigurasi memberi tahu Kubernetes cara men-deploy hybrid komponen ke sebuah cluster. Selanjutnya, Anda akan mengaktifkan akses sinkronisasi sehingga Bidang manajemen dan runtime Apigee akan dapat berkomunikasi.
