cloudformation実行用インスタンス

• Amazon Linux AMI 2014.09.1 (HVM) - ami-4985b048

sudo yum update
sudo yum install git jq
sudo pip install jmespath-terminal

curl -kL https://raw.github.com/pypa/pip/master/contrib/get-pip.py | sudo python
sudo pip install virtualenv virtualenvwrapper
sudo pip install autoenv

vi ~/.bashrc
# User specific aliases and functions
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Devel
source `which virtualenvwrapper.sh`
source `which activate.sh`

git clone [email protected]:twingo-b/cloudformation_troposphere.git
cd cloudformation_troposphere
pip install -r requirements.txt

NATインスタンスのAMI確認

export AWS_DEFAULT_REGION='ap-northeast-1'
aws ec2 describe-images --owners amazon > describe-images.json
# jmespath-terminal でquery作成
jpterm describe-images.json

aws ec2 describe-images --owners amazon --query 'Images[?starts_with(to_string(Name),`amzn-ami-vpc-nat-hvm`) == `true`].{Name:Name,ImageId:ImageId}' | jq .
[
  {
    "Name": "amzn-ami-vpc-nat-hvm-2014.09.1.x86_64-gp2",
    "ImageId": "ami-27d6e626"
  },
  {
    "Name": "amzn-ami-vpc-nat-hvm-2014.03.2.x86_64-gp2",
    "ImageId": "ami-49c29e48"
  },
  {
    "Name": "amzn-ami-vpc-nat-hvm-2014.03.2.x86_64-ebs",
    "ImageId": "ami-55c29e54"
  }
]

NATインスタンスのkey作成

aws ec2 create-key-pair --key-name gameday

CloudFormation起動と停止

起動

python gen-vpc-with-public-and-private-subnets.py > $HOME/gen-vpc-with-public-and-private-subnets.json
export AWS_DEFAULT_REGION='ap-northeast-1'
aws cloudformation create-stack --stack-name gameday --template-body file:////home//ec2-user//gen-vpc-with-public-and-private-subnets.json
{
    "StackId": "arn:aws:cloudformation:ap-northeast-1:<account_num>:stack/gameday/9e210a00-7ddc-11e4-a549-5088487c4896"
}

停止

aws cloudformation delete-stack --stack-name gameday
