Mulai menggunakan Amazon VPC IPAM menggunakan CLI

Contoh kode berikut ini menunjukkan cara untuk melakukan:

  • Siapkan dan konfigurasikan Amazon VPC IP Address Manager (IPAM) menggunakan CLI.

  • Buat IPAM dengan wilayah operasi (misalnya, us-east-1, us-west-2).

  • Ambil ID cakupan pribadi untuk IPAM.

  • Buat struktur hierarkis IPv4 kolam (kolam tingkat atas, regional, dan pengembangan).

  • Menyediakan blok CIDR untuk setiap kumpulan (misalnya, 10.0.0.0/8, 10.0.0.0/16, 10.0.0.0/24).

  • Buat VPC menggunakan CIDR yang dialokasikan dari kolam IPAM.

  • Verifikasi alokasi kolam IPAM dan pembuatan VPC.

  • Memecahkan masalah umum seperti kesalahan izin, kegagalan alokasi CIDR, dan pelanggaran ketergantungan.

  • Bersihkan sumber daya IPAM (VPC, pool CIDRs, dan IPAM) untuk menghindari biaya yang tidak perlu.

  • Jelajahi langkah selanjutnya untuk fitur IPAM tingkat lanjut.
