AWS CloudFormation 部署覆盖“名称”标签？

Question

I like not specifying custom names for my resources (because of how CF won't rebuild them if changed)

But it would be nice if I could change the "name" tag at deploy time, for example:

aws cloudformation deploy --template-file dev-cf.yaml --stack-name mystack --region us-east-1 --tags Name=myapp env=dev

Will this work or break anything? Does CF depend on the "name" tag of resources it creates?

No, CF does not depend on Name tags, name tags are largely for your/sysadmins benefit. I haven't used many name tags (that's probably not a good thing) throughout a lot of stuff I've written and I've never had issues. The only thing that I can see being a possibility, is that CF does use some values/resource attrs/cf resource names to generate the CF specific names for things, so they may take your Name tags into consideration for generating those, but other than that, you'll be fine.
