v1.1.0: tags

• Support YAML stack tag files via --tags (details below)
• Use Go modules (Go 1.11+) rather than dep.

Stack Tags

CloudFormation stacks can be tagged, and those tags flow into all taggable resources the stack creates. As with --parameters, the aws cloudformation commands expect these in an awkward format. cfparams --tags file.yaml helps.

# tags-production.yaml
Name: Widgets as a Service
asset: widget-api
workload: production

cfparams --tags=tags-production.yaml

[
  {
    "Key": "Name",
    "Value": "Widgets as a Service"
  },
  {
    "Key": "asset",
    "Value": "widget-api"
  },
  {
    "Key": "workload",
    "Value": "production"
  }
]

Usage with AWS CLI:

aws cloudformation create-stack \
  ... \
  --tags "$(cfparams --tags=tags-production.yaml)" \
  ...
