How do I add to or change a stack's tags?

Question

I have an existing AWS CloudFormation stack, and I would like to add an additional tag to the stack. I went through the "Update Stack" UI steps, but didn't see anything that allows me to update the tag.

Is it possible to add a tag to an existing tag, and if so, how?

Answer 1

You can update the tags on an existing stack by running update-stack for the aws cli:

$ aws cloudformation update-stack --stack-name myStack --template-body file://myCloudformationTemplate.yaml --tags='[{"Key": "Author","Value": "Me"}, {"Key": "Project", "Value": "Foo"}]'
