            Amazon Elastic Compute Cloud (EC2) is a web service that provides secure, resizable compute 
            capacity in the cloud. It allows developers and organizations to easily launch and manage 
            virtual server instances, known as EC2 instances, to run their applications.
                        
            EC2 provides a wide range of instance types, each with different compute, memory, 
            and storage capabilities, to meet the diverse needs of various workloads. Developers 
            can choose the appropriate instance type based on their application's requirements, 
            such as high-performance computing, memory-intensive tasks, or GPU-accelerated workloads.
                        
            The `Ec2AsyncClient` interface in the AWS SDK for Java 2.x provides a set of methods to 
            programmatically interact with the Amazon EC2 service. This allows developers to 
            automate the provisioning, management, and monitoring of EC2 instances as part of their 
            application deployment pipelines. With EC2, teams can focus on building and deploying 
            their applications without having to worry about the underlying infrastructure 
            required to host and manage physical servers.

            An Elastic IP address is a static public IP address that you can associate with your EC2 instance.

            is stopped, terminated, or replaced. 
            This is particularly useful for applications or services that need to be accessed consistently from a

            When you purchase a Reserved Instance, AWS assigns a unique Allocation ID to it. 
            This Allocation ID is used to track and identify the specific RI you have purchased, 
            and it is important for managing and monitoring your Reserved Instances.

//! Scenario that uses the AWS SDK for Rust (the SDK) with Amazon Elastic Compute Cloud
//! (Amazon EC2) to do the following:
//!
//! * Create a key pair that is used to secure SSH communication between your computer and
//!   an EC2 instance.
//! * Create a security group that acts as a virtual firewall for your EC2 instances to
//!   control incoming and outgoing traffic.
//! * Find an Amazon Machine Image (AMI) and a compatible instance type.
//! * Create an instance that is created from the instance type and AMI you select, and
//!   is configured to use the security group and key pair created in this example.
//! * Stop and restart the instance.
//! * Create an Elastic IP address and associate it as a consistent IP address for your instance.
//! * Connect to your instance with SSH, using both its public IP address and your Elastic IP
//!   address.
//! * Clean up all of the resources created by this example.

#### [ CLI ]

**AWS CLI**  
**範例 1：新增規則，以允許傳入 SSH 流量**  
以下 `authorize-security-group-ingress` 範例會新增規則，以允許 TCP 連接埠 22 (SSH) 上的傳入流量。  

```
aws ec2 authorize-security-group-ingress \
    --group-id sg-1234567890abcdef0 \
    --protocol tcp \
    --port 22 \
    --cidr 203.0.113.0/24
```
輸出：  

```
{
    "Return": true,
    "SecurityGroupRules": [
        {
            "SecurityGroupRuleId": "sgr-01afa97ef3e1bedfc",
            "GroupId": "sg-1234567890abcdef0",
            "GroupOwnerId": "123456789012",
            "IsEgress": false,
            "IpProtocol": "tcp",
            "FromPort": 22,
            "ToPort": 22,
            "CidrIpv4": "203.0.113.0/24"
        }
    ]
}
```
**範例 2：新增規則，以允許來自其他安全群組的傳入 HTTP 流量**  
下列 `authorize-security-group-ingress` 範例會新增規則，以允許 TCP 連接埠 80 上來自來源安全群組 `sg-1a2b3c4d` 的傳入存取。來源群組必須在相同 VPC 或對等 VPC 中 (需要 VPC 對等互連)。傳入流量會根據與來源安全群組相關聯之執行個體的私有 IP 位址允許 (而非公有 IP 位址或彈性 IP 位址)。  

```
aws ec2 authorize-security-group-ingress \
    --group-id sg-1234567890abcdef0 \
    --protocol tcp \
    --port 80 \
    --source-group sg-1a2b3c4d
```
輸出：  

```
{
    "Return": true,
    "SecurityGroupRules": [
        {
            "SecurityGroupRuleId": "sgr-01f4be99110f638a7",

            "FromPort": 80,
            "ToPort": 80,
            "ReferencedGroupInfo": {
                "GroupId": "sg-1a2b3c4d",
                "UserId": "123456789012"
            }
        }
    ]
}
```
**範例 3：在相同的呼叫中新增多個規則**  
下列 `authorize-security-group-ingress` 範例會使用 `ip-permissions` 參數來新增兩個傳入規則；一個規則可在 TCP 連接埠 3389 (RDP) 上啟用傳入存取，另一個規則可啟用 Ping/ICMP。  

```
aws ec2 authorize-security-group-ingress \
    --group-id sg-1234567890abcdef0 \
    --ip-permissions 'IpProtocol=tcp,FromPort=3389,ToPort=3389,IpRanges=[{CidrIp=172.31.0.0/16}]' 'IpProtocol=icmp,FromPort=-1,ToPort=-1,IpRanges=[{CidrIp=172.31.0.0/16}]'
```

            "FromPort": 3,
            "ToPort": 4,
            "CidrIpv4": "0.0.0.0/0"
        }
    ]
}
```
**範例 5：為 IPv6 流量新增規則**  
下列 `authorize-security-group-ingress` 範例會使用 `ip-permissions` 參數新增傳入規則，以允許來自 IPv6 範圍 `2001:db8:1234:1a00::/64` 的 SSH 存取 (連接埠 22)。  

```
aws ec2 authorize-security-group-ingress \
    --group-id sg-1234567890abcdef0 \
    --ip-permissions 'IpProtocol=tcp,FromPort=22,ToPort=22,Ipv6Ranges=[{CidrIpv6=2001:db8:1234:1a00::/64}]'
```
輸出：  

```
{
    "Return": true,
    "SecurityGroupRules": [
        {
            "SecurityGroupRuleId": "sgr-0455bc68b60805563",

#### [ CLI ]

**AWS CLI**  
**範例 1：建立啟動範本**  
以下 `create-launch-template` 範例會建立啟動範本，而此範本可指定執行個體啟動所在的子網路、將公有 IP 位址和 IPv6 位址指派給執行個體，並為執行個體建立標籤。  

```
aws ec2 create-launch-template \
    --launch-template-name TemplateForWebServer \
    --version-description WebVersion1 \
    --launch-template-data '{"NetworkInterfaces":[{"AssociatePublicIpAddress":true,"DeviceIndex":0,"Ipv6AddressCount":1,"SubnetId":"subnet-7b16de0c"}],"ImageId":"ami-8c1be5f6","InstanceType":"t2.small","TagSpecifications":[{"ResourceType":"instance","Tags":[{"Key":"purpose","Value":"webserver"}]}]}'
```
輸出：  

```

**範例 2：為 Amazon EC2 Auto Scaling 建立啟動範本**  
以下 `create-launch-template` 範例會建立具備多個標籤和區塊型裝置映射的啟動範本，以指定執行個體啟動時的額外 EBS 磁碟區。請為 `Groups`，即對應至 Auto Scaling 群組在其中啟動執行個體的 VPC 安全群組指定數值。將 VPC 和子網路指定為 Auto Scaling 群組的屬性。  

```

#### [ CLI ]

**AWS CLI**  
**範例 1：將標籤新增至資源**  
以下 `create-tags` 範例會將標籤 `Stack=production` 新增至指定的映像，或覆寫 AMI 的現有標籤，其中標籤金鑰為 `Stack`。  

```
aws ec2 create-tags \
    --resources ami-1234567890abcdef0 \
    --tags Key=Stack,Value=production
```
此命令不會產生輸出。  
**範例 2：將標籤新增至多個資源**  
下列 `create-tags` 範例會為 AMI 和執行個體新增 (或覆寫) 兩個標籤。其中一個標籤具有索引鍵 (`webserver`)，但沒有值 (值會設定為空白字串)。另一個標籤則有一個索引鍵 (`stack`) 和一個值 (`Production`)。  

```
aws ec2 create-tags \
    --resources ami-1a2b3c4d i-1234567890abcdef0 \
    --tags Key=webserver,Value=   Key=stack,Value=Production
```
此命令不會產生輸出。  
**範例 3：新增包含特殊字元的標籤**  
下列 `create-tags` 範例為執行個體新增標籤 `[Group]=test`。中括號 ([ 和 ]) 是特殊字元，必須將其逸出。下列範例也會使用每個環境適用的行接續字元。  
如果您使用 Windows，請以雙引號 (") 括住具有特殊字元的元素，然後在每個雙引號字元前面加上反斜線 (\$1)，如下所示。  

```
aws ec2 create-tags ^
    --resources i-1234567890abcdef0 ^
    --tags Key=\"[Group]\",Value=test
```
如果您使用 Windows PowerShell，請以雙引號 (") 括住具有特殊字元的元素，在每個雙引號字元前面加上反斜線 (\$1)，然後用單引號 (') 括住整個索引鍵和值結構，如下所示。  

```
aws ec2 create-tags `
    --resources i-1234567890abcdef0 `
    --tags 'Key=\"[Group]\",Value=test'
```
如果您是使用 Linux 或 OS X，請以雙引號 (") 括住具有特殊字元的值，然後使用單引號 (') 括住整個索引鍵和值結構，如下所示。  

```
aws ec2 create-tags \
    --resources i-1234567890abcdef0 \
    --tags 'Key="[Group]",Value=test'
```

# 搭配使用 `CreateVolume` 與 CLI
<a name="example_ec2_CreateVolume_section"></a>

下列程式碼範例示範如何使用 `CreateVolume`。

------
#### [ CLI ]

**AWS CLI**  
**建立空的一般用途 SSD (gp2) 磁碟區**  
下列 `create-volume` 範例會在指定的可用區域中，建立 80 GiB 一般用途 SSD (gp2) 磁碟區。請注意，目前區域必須是 `us-east-1`，或者您可以新增 `--region` 參數來指定命令施行的區域。  

```
aws ec2 create-volume \
    --volume-type gp2 \
    --size 80 \
    --availability-zone us-east-1a
```
輸出：  

```
{
    "AvailabilityZone": "us-east-1a",
    "Tags": [],
    "Encrypted": false,
    "VolumeType": "gp2",
    "VolumeId": "vol-1234567890abcdef0",
    "State": "creating",
    "Iops": 240,
    "SnapshotId": "",
    "CreateTime": "YYYY-MM-DDTHH:MM:SS.000Z",
    "Size": 80
}
```
如果您未指定磁碟區類型，則預設磁碟區類型為 `gp2`。  

```
aws ec2 create-volume \
    --size 80 \
    --availability-zone us-east-1a
```
**範例 2：從快照建立佈建 IOPS SSD (io1) 磁碟區**  
下列 `create-volume` 範例使用指定的快照，在指定的可用區域中建立具有 1000 個佈建 IOPS 的佈建 IOPS SSD (io1) 磁碟區。  

```
aws ec2 create-volume \
    --volume-type io1 \
    --iops 1000 \
    --snapshot-id snap-066877671789bd71b \
    --availability-zone us-east-1a
```
輸出：  

```
{
    "AvailabilityZone": "us-east-1a",
    "Tags": [],
    "Encrypted": false,
    "VolumeType": "io1",
    "VolumeId": "vol-1234567890abcdef0",
    "State": "creating",
    "Iops": 1000,
    "SnapshotId": "snap-066877671789bd71b",
    "CreateTime": "YYYY-MM-DDTHH:MM:SS.000Z",
    "Size": 500
}
```
**範例 3：建立加密磁碟區**  
下列 `create-volume` 範例使用 EBS 加密的預設 CMK 建立加密磁碟區。如果預設停用加密，您必須指定 `--encrypted` 參數，如下所示。  

```
aws ec2 create-volume \
    --size 80 \
    --encrypted \
    --availability-zone us-east-1a
```
輸出：  

```
{
    "AvailabilityZone": "us-east-1a",
    "Tags": [],
    "Encrypted": true,
    "VolumeType": "gp2",
    "VolumeId": "vol-1234567890abcdef0",
    "State": "creating",
    "Iops": 240,
    "SnapshotId": "",
    "CreateTime": "YYYY-MM-DDTHH:MM:SS.000Z",
    "Size": 80
}
```
如果預設啟用加密，即使沒有 `--encrypted` 參數，下列範例命令也會建立加密的磁碟區。  

```
aws ec2 create-volume \
    --size 80 \
    --availability-zone us-east-1a
```
如果您使用 `--kms-key-id` 參數來指定客戶管理的 CMK，即使預設為啟用加密，您都必須指定 `--encrypted` 參數。  

```
aws ec2 create-volume \
    --volume-type gp2 \
    --size 80 \
    --encrypted \
    --kms-key-id 0ea3fef3-80a7-4778-9d8c-1c0c6EXAMPLE \
    --availability-zone us-east-1a
```
**範例 4：使用標籤建立磁碟區**  
下列 `create-volume` 範例會建立磁碟區，並新增兩個標籤。  

```
aws ec2 create-volume \
    --availability-zone us-east-1a \
    --volume-type gp2 \
    --size 80 \
    --tag-specifications 'ResourceType=volume,Tags=[{Key=purpose,Value=production},{Key=cost-center,Value=cc123}]'
```

**範例 2：描述具有特定規則的安全群組**  
下列 `describe-security-groups` 範例使用篩選條件，將結果範圍限定為具有允許 SSH 流量 (連接埠 22) 之規則的安全群組，以及允許來自所有位址 (`0.0.0.0/0`) 之流量的規則。此範例使用 `--query` 參數，僅顯示安全群組的名稱。安全群組必須符合所有篩選條件才能在結果中傳回；不過，單一規則不需要符合所有篩選條件。例如，輸出會傳回一個安全群組，其中包含允許來自特定 IP 位址之 SSH 流量的一個規則，以及允許來自所有地址之 HTTP 流量的另一個規則。  

```
aws ec2 describe-security-groups \
    --filters Name=ip-permission.from-port,Values=22 Name=ip-permission.to-port,Values=22 Name=ip-permission.cidr,Values='0.0.0.0/0' \
    --query "SecurityGroups[*].[GroupName]" \
    --output text
```
輸出：  

```
default
my-security-group
web-servers
launch-wizard-1
```
**範例 3：根據標籤描述安全群組**  
下列 `describe-security-groups` 範例會使用篩選條件，將結果範圍限定為在安全群組名稱中加入 `test`，且具有標籤 `Test=To-delete` 的安全群組。此範例使用 `--query` 參數，僅顯示安全群組的名稱和 ID。  

```
aws ec2 describe-security-groups \
    --filters Name=group-name,Values=*test* Name=tag:Test,Values=To-delete \
    --query "SecurityGroups[*].{Name:GroupName,ID:GroupId}"
```
輸出：  

```
[

        "Name": "testfornewinstance",
        "ID": "sg-33bb22aa"
    },
    {
        "Name": "newgrouptest",

    --snapshot-ids snap-1234567890abcdef0
```
輸出：  

```
{
    "Snapshots": [
        {
            "Description": "This is my snapshot",
            "Encrypted": false,
            "VolumeId": "vol-049df61146c4d7901",
            "State": "completed",
            "VolumeSize": 8,
            "StartTime": "2019-02-28T21:28:32.000Z",
            "Progress": "100%",
            "OwnerId": "012345678910",
            "SnapshotId": "snap-01234567890abcdef",
            "Tags": [
                {
                    "Key": "Stack",
                    "Value": "test"
                }
            ]
        }

**範例 2：根據篩選條件描述快照**  
下列`describe-snapshots`範例使用篩選條件，將結果範圍限定為 AWS 帳戶擁有且`pending`處於 狀態的快照。此範例使用 `--query` 參數，僅顯示快照 ID 和快照啟動時間。  

```
aws ec2 describe-snapshots \
    --owner-ids self \
    --filters Name=status,Values=pending \
    --query "Snapshots[*].{ID:SnapshotId,Time:StartTime}"
```
輸出：  

```
[
    {
        "ID": "snap-1234567890abcdef0",
        "Time": "2019-08-04T12:48:18.000Z"
    },
    {
        "ID": "snap-066877671789bd71b",
        "Time": "2019-08-04T02:45:16.000Z
    },
    ...
]
```
下列 `describe-snapshots` 範例會使用篩選條件，將結果範圍限制為從指定磁碟區建立的快照。此範例使用 `--query` 參數，僅顯示快照 ID。  

```
aws ec2 describe-snapshots \
    --filters Name=volume-id,Values=049df61146c4d7901 \
    --query "Snapshots[*].[SnapshotId]" \
    --output text
```
輸出：  

```
snap-1234567890abcdef0

**範例 2：在非預設的子網路中啟動執行個體，並新增公有 IP 位址**  
下列 `run-instances` 範例會針對您要在非預設的子網路中啟動的執行個體請求公有 IP 位址。執行個體已與指定的安全群組建立關聯。  

```
aws ec2 run-instances \
    --image-id ami-0abcdef1234567890 \
    --instance-type t2.micro \
    --subnet-id subnet-08fc749671b2d077c \
    --security-group-ids sg-0b0384b66d7d692f9 \
    --associate-public-ip-address \
    --key-name MyKeyPair
```
如需 `run-instances` 的輸出範例，請參閱範例 1。  
**範例 3：啟動具有額外磁碟區的執行個體**  
下列 `run-instances` 範例會使用 mapping.json 中指定的區塊型裝置映射，在啟動時連接額外的磁碟區。區塊型裝置映射可以指定 EBS 磁碟區、執行個體儲存體磁碟區，或同時指定 EBS 磁碟區和執行個體儲存體磁碟區。  

```
aws ec2 run-instances \
    --image-id ami-0abcdef1234567890 \
    --instance-type t2.micro \
    --subnet-id subnet-08fc749671b2d077c \
    --security-group-ids sg-0b0384b66d7d692f9 \
    --key-name MyKeyPair \
    --block-device-mappings file://mapping.json
```
`mapping.json` 的內容。此範例會為 `/dev/sdh` 新增空的 EBS 磁碟區 (大小為 100 GiB)。  

```
[
    {
        "DeviceName": "/dev/sdh",
        "Ebs": {
            "VolumeSize": 100
        }
    }
]
```
`mapping.json` 的內容。此範例會將 `ephemeral1` 新增為執行個體儲存體磁碟區。  

```
[
    {
        "DeviceName": "/dev/sdc",
        "VirtualName": "ephemeral1"
    }
]
```

**範例 4：啟動執行個體並在建立時新增標籤**  
下列 `run-instances` 範例會將索引鍵為 `webserver`、值為 `production` 的標籤新增至執行個體。命令也會為任何建立的 EBS 磁碟區 (此範例中為根磁碟區) 套用鍵為 `cost-center`，值為 `cc123` 的標籤。  

```
aws ec2 run-instances \
    --image-id ami-0abcdef1234567890 \
    --instance-type t2.micro \
    --count 1 \
    --subnet-id subnet-08fc749671b2d077c \
    --key-name MyKeyPair \
    --security-group-ids sg-0b0384b66d7d692f9 \
    --tag-specifications 'ResourceType=instance,Tags=[{Key=webserver,Value=production}]' 'ResourceType=volume,Tags=[{Key=cost-center,Value=cc123}]'
```
如需 `run-instances` 的輸出範例，請參閱範例 1。  
**範例 5：使用使用者資料啟動執行個體**  
下列 `run-instances` 範例會將使用者資料傳遞至名為 `my_script.txt` 的檔案中，且該檔案包含您執行個體的組態指令碼。指令碼會在啟動時執行。  

```
aws ec2 run-instances \
    --image-id ami-0abcdef1234567890 \
    --instance-type t2.micro \
    --count 1 \
    --subnet-id subnet-08fc749671b2d077c \
    --key-name MyKeyPair \
    --security-group-ids sg-0b0384b66d7d692f9 \
    --user-data file://my_script.txt
```

**範例 6：啟動爆量效能執行個體**  
下列 `run-instances` 範例會啟動具有 `unlimited` 積分選項的 t2.micro 執行個體。啟動 T2 執行個體時，如果您未指定 `--credit-specification`，預設值為 `standard` 積分選項。啟動 T3 執行個體時，預設值為 `unlimited` 積分選項。  

```
aws ec2 run-instances \
    --image-id ami-0abcdef1234567890 \
    --instance-type t2.micro \
    --count 1 \
    --subnet-id subnet-08fc749671b2d077c \

#### [ CLI ]

**AWS CLI**  
**範例 1：停止 Amazon EC2 執行個體**  
下列 `stop-instances` 範例會停止指定且受 Amazon EBS 支援的執行個體。  

```
aws ec2 stop-instances \
    --instance-ids i-1234567890abcdef0
```
輸出：  

```
{
    "StoppingInstances": [
        {
            "InstanceId": "i-1234567890abcdef0",
            "CurrentState": {
                "Code": 64,
                "Name": "stopping"
            },
            "PreviousState": {
                "Code": 16,
                "Name": "running"
            }
        }
    ]
}
```
如需詳細資訊，請參閱*《Amazon Elastic Compute Cloud 使用者指南》*中的[停止和啟動執行個體](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Stop_Start.html)。  
**範例 2：讓 Amazon EC2 執行個體休眠**  
下列 `stop-instances` 範例會在 Amazon EBS 已啟用休眠並符合休眠必要條件時，讓該執行個體進入休眠。執行個體進入休眠狀態之後，即停止運作。  

```
aws ec2 stop-instances \
    --instance-ids i-1234567890abcdef0 \
    --hibernate
```
輸出：  

```
{
    "StoppingInstances": [
        {
            "CurrentState": {
                "Code": 64,

使用 Waiters API，等待執行個體處於終止狀態。使用 Waiters API 時，需要在 rust 檔案中使用 `use aws\$1sdk\$1ec2::client::Waiters`。  

```
    async fn wait_for_instance_terminated(&self, instance_id: &str) -> Result<(), EC2Error> {
        self.client
            .wait_until_instance_terminated()
            .instance_ids(instance_id)
            .wait(Duration::from_secs(60))
            .await
            .map_err(|err| match err {
                WaiterError::ExceededMaxWait(exceeded) => EC2Error(format!(
                    "Exceeded max time ({}s) waiting for instance to terminate.",
                    exceeded.max_wait().as_secs(),
