Contoh 2: Untuk mendeskripsikan 100 grup Auto Scaling pertama yang ditentukan

Contoh ini menjelaskan grup Auto Scaling yang ditentukan. Ini memungkinkan Anda untuk menentukan hingga 100 nama grup.

aws autoscaling describe-auto-scaling-groups \
    --max-items 100 \
    --auto-scaling-group-names "group1" "group2" "group3" "group4"

Lihat contoh 1 untuk output sampel.

Contoh 3: Untuk mendeskripsikan grup Auto Scaling di wilayah tertentu

Contoh ini menjelaskan grup Auto Scaling di wilayah tertentu, hingga maksimal 75 grup.

aws autoscaling describe-auto-scaling-groups \
    --max-items 75 \
    --region us-east-1

Lihat contoh 1 untuk output sampel.

Contoh 4: Untuk menjelaskan jumlah grup Auto Scaling yang ditentukan

Untuk mengembalikan sejumlah grup Auto Scaling tertentu, gunakan opsi. --max-items

aws autoscaling describe-auto-scaling-groups \
    --max-items 1

Lihat contoh 1 untuk output sampel.

Jika output termasuk NextToken bidang, ada lebih banyak grup. Untuk mendapatkan grup tambahan, gunakan nilai bidang ini dengan --starting-token opsi dalam panggilan berikutnya sebagai berikut.

aws autoscaling describe-auto-scaling-groups \
    --starting-token Z3M3LMPEXAMPLE

Lihat contoh 1 untuk output sampel.

Contoh 5: Untuk menjelaskan grup Auto Scaling yang menggunakan konfigurasi peluncuran

Contoh ini menggunakan --query opsi untuk mendeskripsikan grup Auto Scaling yang menggunakan konfigurasi peluncuran.

aws autoscaling describe-auto-scaling-groups \
    --query 'AutoScalingGroups[?LaunchConfigurationName!=`null`]'

Output:
