CloudFormation Commands

sync templates to S3 bucket

Creating and updating stacks requires a template that is located in an S3 bucket. We provide the bucket URL in the create-stack and update-stack commands with the --template-url option.

aws s3 sync . s3://briancaffey.com-cloudformation/

validate-template

The following command can be used to validate CloudFormation templates locally:

aws cloudformation validate-template --template-body file:///home/brian/gitlab/briancaffey.com/cloudformation/master.yaml

The above command will have this output:

{
    "Description": "\nThis template deploys a VPC, with a pair of public and private subnets spread across two Availabilty Zones. It deploys an Internet Gateway, with a default route on the public subnets. It deploys a pair of NAT Gateways (one in each AZ), and default routes for them in the private subnets.\nIt then deploys a highly available ECS cluster using an AutoScaling Group, with ECS hosts distributed across multiple Availability Zones.\nFinally, it deploys a pair of example ECS services from co
    ntainers published in Amazon EC2 Container Registry(Amazon ECR).\nLast Modified: 22n d September 2016 Author: Paul Maddox < pmad

    "CapabilitiesReason": "The following resource(s) require capabilities: [AWS::CloudFormation::Stack]",
    "Parameters": [],
    "Capabilities": [
        "CAPABILITY_NAMED_IAM",
        "CAPABILITY_AUTO_EXPAND"
    ]
}

create-stack

aws cloudformation create-stack --stack-name briancaffey --template-url https://s3.amazonaws.com/briancaffey.com-cloudformation/master.yaml --capabilities=CAPABILITY_NAMED_IAM

update-stack

aws cloudformation update-stack --stack-name briancaffey --template-url https://s3.amazonaws.com/briancaffey.com-cloudformation/master.yaml --capabilities=CAPABILITY_NAMED_IAM

Enable SSH Access to EC2 Instances with KeyPair

aws-samples/ecs-refarch-cloudformation#62

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-as-launchconfig.html#cfn-as-launchconfig-keyname

Also, we need to update a security group rule to allow SSH connections on port 22.

TODO

• Tear down the stack (click the button that says delete stack)

• Make sure that we have documented the changes to make in our template

• static site, ALB certificate, ECR Repo, Comment out the container definition until our stack is up and we have pushed the image to the ECR repo.

Questions

Is it true that you can use either HostedZoneName or HostedZoneId but not both?
