We wanted to use company specific Tags to the resources that we create in AWS for billing purposes. I am using a cloud formation template to spin up our Elasticbeanstalk instance and other project dependent resources. When I use the CloudFormation console to create a stack it asks me for Tags in the page after parameters. I have to manually input the Tags for that stack. However is there a way to specify those Tags (Tags for the stack) with in the cloud formation template itself? That way the Tag gets propagated to the other resources? I know that the cloud formation automatically tags the resources with the stack name. But we need company specific tags to bill separate departments.

In the template anatomy, you can't set stack-level tags directly. However you can create a wrapper template, having a single resource of AWS::CloudFormation::Stack
.
You can define stack-level tags on that resource:
{
"AWSTemplateFormatVersion": "2010-09-09",
"Description": "WrapperTemplate",
"Resources": {
"WrappedStackWithStackLevelTags": {
"Type" : "AWS::CloudFormation::Stack",
"Properties" : {
"Tags" : [ { "Key" : "Stage", "Value" : "QA" } ],
"TemplateURL" : "your-original-template-s3-url"
}
}
}
}

I didn't even know this was an option... this is incredibly helpful for much more than just tag inheritance. Feb 16, 2017 at 19:59

1Is this how you would set SNS Topic for the entire stack from within the template? May 4, 2018 at 15:43

Man Incredibly useful!! Should update the title to include "cloud formation stack level tags"– user6434796May 21, 2018 at 17:09

4Can this be used without setting the templateUrl? I don't want to create a nested stack– lvthilloFeb 28, 2019 at 20:03
When launching AWS CloudFormation, the tags being requested will be applied to the CloudFormation Stack itself and (where possible) will also be propagated to the resources launched by the Stack.
These tags can be passed to the CreateStack API call, or from the CLI:
These tags are applied to the whole Stack and aren't included in the CloudFormation template.
However, CloudFormation templates can include tags for specific resources that are being created. For example, when launching Amazon EC2 instances, tags can be included in the template:
"MyInstance" : {
"Type" : "AWS::EC2::Instance",
"Properties" : {
"SecurityGroups" : [{ "Ref" : "MySecurityGroup" }],
"AvailabilityZone" : "us-east-1a",
"ImageId" : "ami-20b65349",
"Volumes" : [{
"VolumeId" : { "Ref" : "MyEBS" },
"Device" : "/dev/sdk"
}],
"Tags" : [{
"Key" : "Stage",
"Value" : "QA"
}]
}
}

Thanks John. (where possible) is the hint that I needed. Tagging an elastic Beanstalk environment is not supported through cloudformation , however you can tag it Manually. I was assuming if it supported to TAg through console it should be able to be done through cloud formation and I was wrong. Dec 18, 2014 at 19:34

7Tag propagation in CloudFormation has been a bit unpredictable in my experience. It's disappointing since the documentation claims, "All stack-level tags, including automatically created tags, are propagated to resources that AWS CloudFormation supports."– ShannonSep 10, 2015 at 15:09
Contrary to what @lalyos says, you don't need to use nested stacks for this, just provide the tags that should apply to all resources as stack level tags.
These stack-level tags can be specified whether running the stack on the console or via CLI.
CLI example:
aws cloudformation create-stack --stack-name my-stack-name \
--template-body file://path-to-template-file.yaml \
--parameters ParameterKey=param1key,ParameterValue=param1value \
--tags Key=tag1key,Value=tag1value \
Key=tag2key,Value=tag2value \
Key=tag3key,Value=tag3value
... and generally add as many tags as you need, using the same format and allowing spaces between tag key-value pairs
See: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-console-add-tags.html

You can build and deploy a CloudFormation template using aws-sam-cli
. This command reads a samconfig.toml
file where you can declare tags for all the resources of the stack (including CloudFormation stack itself)
Your samconfig.toml
should look like:
[default.deploy.parameters]
stack_name = "your-application"
s3_bucket = "your-s3-for-cloudformation-stuff"
s3_prefix = "your-folder-name"
...
tags = "Stage=\"QA\""
and then run:
sam build --template <your-cloudformation-template.yml> && sam deploy
-
quick and simple - should be best answer. Tags can also be chained by just using blanks/empty spaces: tags = "Stage=\"QA\" Project=\"xyz\""– snibboDec 19, 2022 at 9:57
You don't need any wrapper.. You can add tags to the stack on when you create/update it:
You can also use the aws cli:
aws cloudformation create-stack help
--tags (list)
Key-value pairs to associate with this stack. CloudFormation also
propagates these tags to supported resources in the stack. You can
specify a maximum number of 50 tags.
If you don't specify this parameter, CloudFormation doesn't modify
the stack's tags. If you specify an empty value, CloudFormation re-
moves all associated tags.
(structure)
The Tag type enables you to specify a key-value pair that can be
used to store information about an CloudFormation stack.
Key -> (string)
Required . A string used to identify this tag. You can spec-
ify a maximum of 128 characters for a tag key. Tags owned by
Amazon Web Services (Amazon Web Services) have the reserved
prefix: aws: .
Value -> (string)
Required . A string containing the value for this tag. You
can specify a maximum of 256 characters for a tag value.
Shorthand Syntax:
Key=string,Value=string ...
JSON Syntax:
[
{
"Key": "string",
"Value": "string"
}
...
]
