创建 Aws Cloudformation Ec2 t2.micro 模板

Question

我想创建一个实例类型为“t2.micro”的 CloudFormation 模板。但是，我找不到有关此实例类型的任何示例。类型为“t2.micro”的ec2需要VPC等

谢谢。

Answer 1

您可以使用以下模板 sn-p。
它将输出 EC2 实例的公共 DNS 名称。

注意：我没有测试过这个模板！

栈下允许创建 EC2 实例，只需指定 VPC id、子网 ID、SG id、实例类型、ami id 等参数，例如你可以在此定义实例类型，默认为 t2,micro。这已成功测试并运行无错误。如果您有任何疑问，请发表评论。######由 MARK Machines 创建 是这样的：

您可以使用我的以下模板，它工作正常。

single-instance.yml

AWSTemplateFormatVersion: 2010-09-09
Description: >-
  AWS CloudFormation Sample Template EC2InstanceWithSecurityGroupSample: Create
  an Amazon EC2 instance running the Amazon Linux AMI. The AMI is chosen based
  on the region in which the stack is run. This example creates an EC2 security
  group for the instance to give you SSH access. **WARNING** This template
  creates an Amazon EC2 instance. You will be billed for the AWS resources used
  if you create a stack from this template.
Parameters:
  KeyName:
    Description: Name of an existing EC2 KeyPair to enable SSH access to the instance
    Type: 'AWS::EC2::KeyPair::KeyName'
    ConstraintDescription: must be the name of an existing EC2 KeyPair.
  InstanceType:
    Description: WebServer EC2 instance type
    Type: String
    Default: t2.micro
    ConstraintDescription: must be a valid EC2 instance type.
  SSHLocation:
    Description: The IP address range that can be used to SSH to the EC2 instances
    Type: String
    MinLength: '9'
    MaxLength: '18'
    Default: 0.0.0.0/0
    AllowedPattern: '(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})/(\d{1,2})'
    ConstraintDescription: must be a valid IP CIDR range of the form x.x.x.x/x.
Mappings:
  AWSInstanceType2Arch:
    t2.micro:
      Arch: HVM64
  AWSInstanceType2NATArch:

      Arch: NATHVM64
  AWSRegionArch2AMI:

      HVM64: ami-0080e4c5bc078760e
      HVMG2: ami-0aeb704d503081ea6
Resources:
  EC2Instance:
    Type: 'AWS::EC2::Instance'
    Properties:
      InstanceType: !Ref InstanceType
      SecurityGroups:
        - !Ref InstanceSecurityGroup
      KeyName: !Ref KeyName
      ImageId: !FindInMap 
        - AWSRegionArch2AMI
        - !Ref 'AWS::Region'
        - !FindInMap 
          - AWSInstanceType2Arch
          - !Ref InstanceType
          - Arch
  InstanceSecurityGroup:
    Type: 'AWS::EC2::SecurityGroup'
    Properties:
      GroupDescription: Enable SSH access via port 22
      SecurityGroupIngress:
        - IpProtocol: tcp
          FromPort: '22'
          ToPort: '22'
          CidrIp: !Ref SSHLocation
Outputs:
  InstanceId:
    Description: InstanceId of the newly created EC2 instance
    Value: !Ref EC2Instance
  AZ:
    Description: Availability Zone of the newly created EC2 instance
    Value: !GetAtt 
      - EC2Instance
      - AvailabilityZone
  PublicDNS:
    Description: Public DNSName of the newly created EC2 instance
    Value: !GetAtt

  PublicIP:
    Description: Public IP address of the newly created EC2 instance
    Value: !GetAtt 
      - EC2Instance
      - PublicIp 

然后运行以下命令：

aws cloudformation create-stack --template-body file://single-instance.yml --stack-name single-instance --parameters ParameterKey=KeyName,ParameterValue=sample ParameterKey=InstanceType,ParameterValue=t2.micro
