[AWS Cloud Shell Error] eksctl: command not found

Problem

當我透過 CloudShell 執行 eksctl 指令出現以下錯誤訊息

[cloudshell-user@ip-10-138-162-6 ~]$ eksctl create cluster -f cluster.yaml 
-bash: eksctl: command not found

Root Cause

若在執行 eksctl 指令時出現 "command not found" 的錯誤，表示您還未安裝 eksctl

確認 security group rule

延伸問題

若 Lambda function 要 revoke security group rule，需賦予以下權限，範例：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "ec2:RevokeSecurityGroupIngress",
            "Resource": "arn:aws:ec2:region:account-id:security-group/sg-xxxxxxxx"
        }
    ]
}

實際例子：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": "ec2:RevokeSecurityGroupIngress",
            "Resource": "arn:aws:ec2:us-east-1:102832830373:security-group/sg-056a6d3af28d29d47"
        }
    ]
}

Using AWS CLI to Encrypt and Decrypt

上傳一個 plain text file 到 AWS CloudShell，並印出內容

[cloudshell-user@ip-10-130-78-240 ~]$ cat ExamplePlaintextFile.txt

建立一個 AWS KMS Key 如下

透過 AWS CLI 加密原 plain text file，並產生一個 EncryptedFile.txt，並印出 EncryptedFile.txt 內容

[cloudshell-user@ip-10-130-78-240 ~]$ aws kms encrypt --key-id alias/AlbertKey --plaintext fileb://ExamplePlaintextFile.txt --output text --query CiphertextBlob | base64 --decode > EncryptedFile.txt

How to read Parameter Store values from Lambda function

已在 Parameter Store 建立兩個參數

已建立以下 Lambda function Code

import boto3
import json

def lambda_handler(event, context):
    # 初始化 SSM 客戶端
    ssm = boto3.client('ssm')
    
    # 參數名稱
    parameters_to_get = [
        '/Dev/DBServer/MySQL/db-user',
        '/Dev/DBServer/MySQL/db-pwd'
    ]
    
    # 從 Parameter Store 獲取參數值
    response = ssm.get_parameters(
        Names=parameters_to_get,
        WithDecryption=True  # 如果參數是加密的，設置為 True
    )
    
    # 初始化一個變數來存儲參數名稱和值
    parameters_values = {}
    
    # 檢查並讀取每個參數的值
    for param in response['Parameters']:
        parameters_values[param['Name']] = param['Value']
    
    # 列印參數值
    print(f"Parameter Values: {json.dumps(parameters_values)}")
    
    return {
        'statusCode': 200,
        'body': json.dumps(f"Parameter Values: {parameters_values}")

如何透過 AWS Lambda 啟動/關閉 EC2

前置作業

假設我已經建立好一台 EC2

已準備一支用 Python 語法寫的 AWS Lambda function（當 EC2 是 Running 狀態時，就 Stop 它；當 EC2 是 Stopped 狀態時，就 Start 它）

import boto3

# 初始化 EC2 客戶端
ec2 = boto3.client('ec2')

def lambda_handler(event, context):
    # 指定要操作的 EC2 實例 ID
    instance_id = 'i-0ebe0819d2efb0cff'

    # 獲取實例的當前狀態
    response = ec2.describe_instances(InstanceIds=[instance_id])
    state = response['Reservations'][0]['Instances'][0]['State']['Name']

    # 根據實例的當前狀態進行操作
    if state == 'running':
        # 如果實例正在運行，則停止它
        stop_response = ec2.stop_instances(InstanceIds=[instance_id])
        action = 'stopped'
    elif state == 'stopped':
        # 如果實例已停止，則啟動它
        start_response = ec2.start_instances(InstanceIds=[instance_id])
        action = 'started'
    else:
        # 如果實例處於其他狀態，不進行操作
        return {
            'statusCode': 400,
            'body': f'Instance {instance_id} is in {state} state, no action taken.'
        }

    # 返回操作結果
    return {
        'statusCode': 200,
        'body': f'Instance {instance_id} has been {action} successfully.'
    }

步驟 4: 配置 AWS CLI (請自行設定自己的 AK 與 SK)

[ec2-user@ip-172-31-28-226 ~]$ aws configure
AWS Access Key ID [None]: AKIASHY4YDRZJLQSTQNU
AWS Secret Access Key [None]: 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
Default region name [None]: us-east-1
Default output format [None]: json

步驟 5: 寫一個 Python 程式來列出 S3 bucket

[ec2-user@ip-172-31-28-226 ~]$ vi list_s3_buckets.py 
[ec2-user@ip-172-31-28-226 ~]$ cat list_s3_buckets.py 
import boto3

def list_buckets():
    # 創建一個 S3 服務客戶端
    s3 = boto3.client('s3')
    
    # 列出所有buckets
    response = s3.list_buckets()
    
    # 輸出 bucket name
    print("S3 Buckets:")
    for bucket in response['Buckets']:
        print(f"- {bucket['Name']}")

if __name__ == '__main__':
    list_buckets()

步驟 6: 執行 Python 程式

[ec2-user@ip-172-31-28-226 ~]$ python3 list_s3_buckets.py

1. 下載 AWS CLI

[ec2-user@ip-172-31-28-226 ~]$ curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 57.3M  100 57.3M    0     0   260M      0 --:--:-- --:--:-- --:--:--  261M

2. 解壓縮下載檔案

[ec2-user@ip-172-31-28-226 ~]$ unzip awscliv2.zip

3. 安裝 AWS CLI

[ec2-user@ip-172-31-28-226 ~]$ sudo ./aws/install
You can now run: /usr/local/bin/aws --version

4. 驗證安裝結果

[ec2-user@ip-172-31-28-226 ~]$ aws --version
aws-cli/2.15.19 Python/3.11.6 Linux/6.1.75-99.163.amzn2023.x86_64 exe/x86_64.amzn.2023 prompt/off

5. 配置 AWS CLI

- AWS Access Key ID 和 AWS Secret Access Key：你可以在 AWS 管理控制台的 IAM 服務中建立一個新的使用者或使用現有的使用者憑證。
- Default region name：輸入你想要操作的 AWS 區域的代碼，例如 us-east-1。
- Default output format：輸入你偏好的輸出格式，常見的選項包括 json、text 和 table。

[ec2-user@ip-172-31-28-226 ~]$ aws configure
AWS Access Key ID [None]: AKIASHY4YDRZJLQSTQNU
AWS Secret Access Key [None]: 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
Default region name [None]: us-east-1
Default output format [None]: json

透過 AWS CLI 進行 S3 操作

1. Create S3 bucket

[ec2-user@ip-172-31-28-226 ~]$ aws s3 mb s3://albert-buckert-154142252146 --region us-east-1
make_bucket: albert-buckert-154142252146

2. List S3 bucket

[ec2-user@ip-172-31-28-226 ~]$ aws s3 ls
2024-02-13 10:02:24 albert-buckert-154142252146

3. Create a file and upload it to S3 bucket

[ec2-user@ip-172-31-28-226 ~]$ echo "Hello World" > hello.txt
[ec2-user@ip-172-31-28-226 ~]$ cat hello.txt
Hello World
[ec2-user@ip-172-31-28-226 ~]$ aws s3 cp hello.txt s3://albert-buckert-154142252146
upload: ./hello.txt to s3://albert-buckert-154142252146/hello.txt 

Send Fanout Event Notifications with Amazon Simple Queue Service (SQS) and Amazon Simple Notification Service (SNS)

步驟 1: 建立 SNS Topic

[cloudshell-user@ip-10-138-176-84 ~]$ aws sns create-topic --name MyFanoutTopic
{
    "TopicArn": "arn:aws:sns:us-east-1:473993628677:MyFanoutTopic"
}

步驟 2: 建立兩個 SQS Queue

[cloudshell-user@ip-10-138-176-84 ~]$ aws sqs create-queue --queue-name MyQueue1
{
    "QueueUrl": "https://sqs.us-east-1.amazonaws.com/473993628677/MyQueue1"
}
[cloudshell-user@ip-10-138-176-84 ~]$ aws sqs create-queue --queue-name MyQueue2
{
    "QueueUrl": "https://sqs.us-east-1.amazonaws.com/473993628677/MyQueue2"
}

步驟 3: 取得兩個 SQS Queue 的 Queue Arn

[cloudshell-user@ip-10-138-176-84 ~]$ aws sqs get-queue-attributes --queue-url "https://sqs.us-east-1.amazonaws.com/473993628677/MyQueue1" --attribute-names "QueueArn"
{
    "Attributes": {
        "QueueArn": "arn:aws:sqs:us-east-1:473993628677:MyQueue1"
    }
}
[cloudshell-user@ip-10-138-176-84 ~]$ aws sqs get-queue-attributes --queue-url "https://sqs.us-east-1.amazonaws.com/473993628677/MyQueue2" --attribute-names "QueueArn"
{
    "Attributes": {
        "QueueArn": "arn:aws:sqs:us-east-1:473993628677:MyQueue2"
    }
}

步驟 4: 到 SQS 編輯 policy

{
  "Id": "Policy1707705888884",
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "Stmt1707705887802",
      "Action": [
        "sqs:SendMessage"
      ],
      "Effect": "Allow",
      "Resource": "arn:aws:sqs:us-east-1:473993628677:MyQueue1",
      "Condition": {
        "ArnEquals": {
          "aws:SourceArn": "arn:aws:sns:us-east-1:473993628677:MyFanoutTopic"
        }
      },
      "Principal": "*"

        }
      },
      "Principal": "*"
    }
  ]
}

步驟 5: 將 SQS Queue 訂閱到 SNS Topic

[cloudshell-user@ip-10-138-176-84 ~]$ aws sns subscribe --topic-arn "arn:aws:sns:us-east-1:473993628677:MyFanoutTopic" --protocol sqs --notification-endpoint "arn:aws:sqs:us-east-1:473993628677:MyQueue1"
{
    "SubscriptionArn": "arn:aws:sns:us-east-1:473993628677:MyFanoutTopic:de6e8885-824b-4450-99ae-8fc3351870d8"
}
[cloudshell-user@ip-10-138-176-84 ~]$ aws sns subscribe --topic-arn "arn:aws:sns:us-east-1:473993628677:MyFanoutTopic" --protocol sqs --notification-endpoint "arn:aws:sqs:us-east-1:473993628677:MyQueue2"
{
    "SubscriptionArn": "arn:aws:sns:us-east-1:473993628677:MyFanoutTopic:0300ef05-afed-480c-9590-a3797e1dd4dc"
}

步驟 6: 向 SNS Topic 發送 message

[cloudshell-user@ip-10-138-176-84 ~]$ aws sns publish --topic-arn "arn:aws:sns:us-east-1:473993628677:MyFanoutTopic" --message "Hello, fanout world!"
{
    "MessageId": "45c4b5e9-0e8c-56b5-a0ff-ebaa871ffe09"
}

步驟 7: 從 SQS Queue 接收 message

[cloudshell-user@ip-10-138-176-84 ~]$ aws sqs receive-message --queue-url "https://sqs.us-east-1.amazonaws.com/473993628677/MyQueue1"
