Editing CloudFormation Templates with VSCode

--

VSCode has a few extensions for CloudFormation templates. The linter makes useful recommendations and is sorely missing from the AWS console.

  1. Install the CloudFormation extension
  2. Install the CloudFormation Linter extension
  3. Complete the installation of the previous extension:

- Terminal/New Terminal
- Run: pip install cfn-lint
- Restart VSCode

4. Press Control-Shift-P (macOS: Command-Shift-P)
5. Select Preferences: Open user settings (JSON)
6. Append the following and save the file

// Custom tags for the parser to use
"yaml.customTags": [
"!And",
"!If",
"!Not",
"!Equals",
"!Or",
"!FindInMap sequence",
"!Base64",
"!Cidr",
"!Ref",
"!Sub",
"!GetAtt",
"!GetAZs",
"!ImportValue",
"!Select",
"!Select sequence",
"!Split",
"!Join sequence"
],
// Enable/disable default YAML formatter (requires restart)
"yaml.format.enable": true
