Contoh 2: Untuk memfilter instans dengan tipe tertentu

Contoh describe-instances berikut menggunakan filter guna mencakup hasil untuk instans dari tipe tertentu.

aws ec2 describe-instances \ --filters Name=instance-type,Values=m5.large

Untuk contoh output, lihat Contoh 1.

Untuk informasi selengkapnya, lihat Daftar dan filter menggunakan Panduan EC2 Pengguna Amazon. CLI

Contoh 3: Untuk memfilter instans dengan tipe dan Zona Ketersediaan tertentu

Contoh describe-instances berikut menggunakan banyak filter guna mencakup hasil untuk instans dengan tipe tertentu yang juga ada di Zona Ketersediaan tertentu.

Untuk contoh output, lihat Contoh 1.

Contoh 4: Untuk memfilter instance dengan tipe tertentu dan Availability Zone menggunakan file JSON

describe-instancesContoh berikut menggunakan file JSON input untuk melakukan pemfilteran yang sama seperti contoh sebelumnya. Ketika filter menjadi lebih rumit, mereka dapat lebih mudah untuk menentukan dalam JSON file.

aws ec2 describe-instances \ --filters file://filters.json

Isi dari filters.json:

[ { "Name": "instance-type", "Values": ["t2.micro", "t3.micro"] }, { "Name": "availability-zone", "Values": ["us-east-2c"] } ]

Untuk contoh output, lihat Contoh 1.

Contoh 5: Untuk memfilter instans dengan tanda Pemilik tertentu

Contoh describe-instances berikut menggunakan filter tanda guna mencakup hasil untuk instans yang memiliki tanda dengan kunci tanda tertentu (Pemilik), terlepas dari nilai tandanya.

aws ec2 describe-instances \ --filters "Name=tag-key,Values=Owner"

Untuk contoh output, lihat Contoh 1.

Contoh 6: Untuk memfilter instans dengan nilai tanda my-team tertentu

Contoh describe-instances berikut menggunakan filter tanda guna mencakup hasil untuk instans yang memiliki tanda dengan kunci tanda tertentu (my-team), terlepas dari nilai tandanya.

aws ec2 describe-instances \ --filters "Name=tag-value,Values=my-team"

Untuk contoh output, lihat Contoh 1.

Contoh 7: Untuk memfilter instans dengan tanda Pemilik dan nilai my-team tertentu

Contoh describe-instances berikut menggunakan filter tanda guna mencakup hasil untuk instans yang memiliki tanda tertentu (Pemilik=my-team).

aws ec2 describe-instances \ --filters "Name=tag:Owner,Values=my-team"

Untuk contoh output, lihat Contoh 1.

Contoh 8: Untuk menampilkan hanya instance dan subnet IDs untuk semua instance

describe-instancesContoh berikut menggunakan --query parameter untuk menampilkan hanya instance dan subnet IDs untuk semua instance, dalam JSON format.

Linux dan macOS:

aws ec2 describe-instances \ --query 'Reservations[*].Instances[*].{Instance:InstanceId,Subnet:SubnetId}' \ --output json

Windows:

aws ec2 describe-instances ^ --query "Reservations[*].Instances[*].{Instance:InstanceId,Subnet:SubnetId}" ^ --output json

Output:

[ { "Instance": "i-057750d42936e468a", "Subnet": "subnet-069beee9b12030077" }, { "Instance": "i-001efd250faaa6ffa", "Subnet": "subnet-0b715c6b7db68927a" }, { "Instance": "i-027552a73f021f3bd", "Subnet": "subnet-0250c25a1f4e15235" } ... ]

Contoh 9: Untuk memfilter instance dari jenis yang ditentukan dan hanya menampilkan instance mereka IDs

describe-instancesContoh berikut menggunakan filter untuk cakupan hasil untuk contoh dari jenis yang ditentukan dan --query parameter untuk menampilkan hanya contohIDs.

aws ec2 describe-instances \ --filters "Name=instance-type,Values=t2.micro" \ --query "Reservations[*].Instances[*].[InstanceId]" \ --output text

Output:

i-031c0dc19de2fb70c i-00d8bff789a736b75 i-0b715c6b7db68927a i-0626d4edd54f1286d i-00b8ae04f9f99908e i-0fc71c25d2374130c

Contoh 10: Untuk memfilter instance dari tipe yang ditentukan dan hanya menampilkan instancenyaIDs, Availability Zone, dan nilai tag yang ditentukan

Contoh describe-instances berikut menampilkan ID instans, Zona Ketersediaan, dan nilai dari tanda Name untuk instans yang memiliki tanda dengan nama tag-key, dalam format tabel.

Linux dan macOS:

aws ec2 describe-instances \ --filters Name=tag-key,Values=Name \ --query 'Reservations[*].Instances[*].{Instance:InstanceId,AZ:Placement.AvailabilityZone,Name:Tags[?Key==`Name`]|[0].Value}' \ --output table

Windows:

aws ec2 describe-instances ^ --filters Name=tag-key,Values=Name ^ --query "Reservations[*].Instances[*].{Instance:InstanceId,AZ:Placement.AvailabilityZone,Name:Tags[?Key=='Name']|[0].Value}" ^ --output table

Output:

------------------------------------------------------------- | DescribeInstances | +--------------+-----------------------+--------------------+ | AZ | Instance | Name | +--------------+-----------------------+--------------------+ | us-east-2b | i-057750d42936e468a | my-prod-server | | us-east-2a | i-001efd250faaa6ffa | test-server-1 | | us-east-2a | i-027552a73f021f3bd | test-server-2 | +--------------+-----------------------+--------------------+

Contoh 11: Untuk menjelaskan instans dalam grup penempatan partisi

Contoh describe-instances berikut menjelaskan instans tertentu. Output-nya mencakup informasi penempatan untuk instans, yang berisi nama grup penempatan dan nomor partisi untuk instans tersebut.

aws ec2 describe-instances \ --instance-ids i-0123a456700123456 \ --query "Reservations[*].Instances[*].Placement"

Output:

[ [ { "AvailabilityZone": "us-east-1c", "GroupName": "HDFS-Group-A", "PartitionNumber": 3, "Tenancy": "default" } ] ]

Untuk informasi selengkapnya, lihat Menjelaskan instance dalam grup penempatan di EC2Panduan Pengguna Amazon.

Contoh 12: Untuk memfilter ke instans dengan grup penempatan dan nomor partisi tertentu

Contoh describe-instances berikut memfilter hasil menjadi hanya instans dengan grup penempatan dan nomor partisi tertentu.

aws ec2 describe-instances \ --filters "Name=placement-group-name,Values=HDFS-Group-A" "Name=placement-partition-number,Values=7"

Berikut ini hanya menunjukkan informasi yang relevan dari output.

"Instances": [ { "InstanceId": "i-0123a456700123456", "InstanceType": "r4.large", "Placement": { "AvailabilityZone": "us-east-1c", "GroupName": "HDFS-Group-A", "PartitionNumber": 7, "Tenancy": "default" } }, { "InstanceId": "i-9876a543210987654", "InstanceType": "r4.large", "Placement": { "AvailabilityZone": "us-east-1c", "GroupName": "HDFS-Group-A", "PartitionNumber": 7, "Tenancy": "default" } ],

Ambil detail untuk sebuah EC2 Instance.

pub async fn describe_instance(&self, instance_id: &str) -> Result<Instance, EC2Error> { let response = self .client .describe_instances() .instance_ids(instance_id) .send() .await?; let instance = response .reservations() .first() .ok_or_else(|| EC2Error::new(format!("No instance reservations for {instance_id}")))? .instances() .first() .ok_or_else(|| { EC2Error::new(format!("No instances in reservation for {instance_id}")) })?; Ok(instance.clone()) }

Setelah membuat EC2 instance, ambil dan simpan detailnya.

/// Create an EC2 instance with the given ID on a given type, using a /// generated KeyPair and applying a list of security groups. pub async fn create( &mut self, ec2: &EC2, image_id: &str, instance_type: InstanceType, key_pair: &KeyPairInfo, security_groups: Vec<&SecurityGroup>, ) -> Result<(), EC2Error> { let instance_id = ec2 .create_instance(image_id, instance_type, key_pair, security_groups) .await?; let instance = ec2.describe_instance(&instance_id).await?; self.instance = Some(instance); Ok(()) }
