Cloud Enterprise Network：Mengaktifkan instance ECS untuk mengakses OSS di lintas wilayah melalui koneksi VPC

Konsol

Terraform

Anda dapat menggunakan Terraform untuk menyiapkan lingkungan dalam topik ini. Untuk detail tentang instalasi dan konfigurasi Terraform, lihat Instal Terraform.

Langkah-langkah di bawah ini menunjukkan cara menjalankan Terraform v1.9.8 pada host Linux. Pastikan Anda telah menyelesaikan Otentikasi.

Langkah 1: Buat sumber daya

1. Buat direktori untuk skenario dan navigasikan ke dalamnya.

   mkdir tf-cen-oss && cd tf-cen-oss

2. Buat file main.tf untuk mendefinisikan sumber daya yang diperlukan.

   touch main.tf

3. Buka file main.tf, tempel kode berikut ke dalam file, dan simpan perubahan. File ini mencakup semua sumber daya dan konfigurasi yang diperlukan.

   variable "pname" {

4. Inisialisasi direktori untuk menyelesaikan pengaturan Terraform.

   terraform init

5. Buat sumber daya. Terraform akan menampilkan pratinjau sumber daya yang akan dibuat. Setelah verifikasi, masukkan yes untuk memulai proses pembuatan.

   terraform apply

Langkah 2: Uji konektivitas

1. Masuk ke instance ECS bernama tf-cen-oss-ecs.

   Alamat masuk untuk instance ECS dapat ditemukan di Output Terraform. Salin alamat ini ke browser dan pilih Temporary SSH Key-based sebagai metode otentikasi.

   

2. Di bagian Output, salin perintah curl:

   

3. Jalankan perintah curl di instance ECS.

   curl tf-cen-oss-xxxxxx.oss-cn-hangzhou-internal.aliyuncs.com/example.txt

   

   Jika konten teks dapat diambil seperti yang ditunjukkan pada gambar, itu menunjukkan akses berhasil.

Langkah 3: Lepaskan sumber daya

Saat verifikasi selesai dan Anda tidak lagi membutuhkan sumber daya tersebut, jalankan perintah berikut untuk melepaskannya dan menghentikan penagihan.

terraform destroy --auto-approve
