Summary

  • Split out of feat(cloudformation): add core lifecycle verbs (apply/diff/delete/validate/output) [EXPERIMENTAL] #2999 (osterman/cfn-phase1-core-lifecycle), whose 154-file diff exceeds CodeRabbit's 150-file-per-review cap on this repo's free-OSS plan.
  • Carries every docs/example/screengrab/fix-log path from that diff (38 files): CLI docs for apply/delete/deploy/diff/output/plan/render/validate, the component-type and stack-config reference pages, the cloudformation lifecycle example, screengrab config and casts, and per-fix docs/fixes/ entries.
  • A follow-up PR (osterman/cfn-phase1-code-rebuild, targeting this branch) carries the remaining ~116 code files on top of this one.

Test plan

🤖 Generated with Claude Code

Summary by CodeRabbit

  • Documentation
    • Added preview documentation for planned AWS CloudFormation commands, component configuration, and stack behavior. The commands are not available in this documentation-only update.
    • Added a CloudFormation example configured for a local emulator; it requires a separate implementation to run.
    • Added command help recordings and investigation reports covering CloudFormation and source-provisioning issues and proposed fixes; this update does not include those fixes.
    • Added title and tags to the YAML functions scaffolding example.
  • Chores
    • Excluded draft documentation from release listings and added a test to verify the behavior.
    • Expanded CLI screengrab validation to cover CloudFormation commands.

📝 Walkthrough

Walkthrough

This pull request adds documentation and a local emulator example for planned native CloudFormation support. It records four fix investigations, adds help recordings and screengrab checks, and excludes draft documents from release-data processing.

Changes

CloudFormation documentation and example

Layer / File(s) Summary
Local CloudFormation example
examples/cloudformation/*
Adds a CloudFormation template, Atmos manifests, Floci emulator configuration, a lifecycle test command, a README, and a runtime ignore rule.
Command reference and help recordings
website/docs/cli/commands/aws/cloudformation/*, website/docs/cli/commands/aws/usage.mdx, website/static/casts/screengrabs/atmos-aws-cloudformation*, demo/casts/atmos.d/screengrabs/cli.yaml
Adds draft command documentation and help recordings. Adds nine CloudFormation help commands to the screengrab validator.
Component reference
website/docs/cli/configuration/components/*, website/docs/components/*, website/docs/stacks/components/aws-cloudformation.mdx, website/plugins/file-browser/index.js, website/sidebars/stacks.test.mjs, examples/scaffolding-yaml-functions/README.md
Documents CloudFormation component configuration, stack fields, source handling, and delivery targets. Updates component references, example tags, and sidebar reachability handling.

Recorded fix reports

Layer / File(s) Summary
Source detection report
docs/fixes/2026-08-31-source-provisioner-single-file-misdetection.md
Records source misdetection, proposed source and archive handling, regression tests, and validation results.
Apply gating and error report
docs/fixes/2026-09-09-cfn-apply-publish-only-gating-and-errors.md
Records proposed gating for stack follow-up calls, stack-not-found error handling, and validation results.
Base-path report
docs/fixes/2026-09-09-cfn-base-path-empty-fallback.md
Records the reported base-path issue, proposed fallback, tests, and validation results.
Packaging credentials report
docs/fixes/2026-09-09-cfn-packaging-default-identity-credentials.md
Records credential-resolution issues, proposed backend construction, tests, and validation results.

Draft document processing

Layer / File(s) Summary
Draft filtering
website/plugins/doc-release-data/index.js, website/plugins/doc-release-data/drafts.test.mjs, website/package.json
Skips documents whose draft value is exactly true during release processing. Adds a test and includes it in the website prebuild test command.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Other

Suggested labels: patch


Merge Risk: 🔵 Low · up to 303e5

This documentation-only change has two small wording inaccuracies that could mislead readers about the template path and about what a non-nil apply result means. Fix them before or shortly after merge; no runtime risk is expected.

Architecture Summary

Architecture risk: 🔵 Low · up to 603db

The change affects 4 systems.

Changed systems: website, examples, docs, demo

Architecture concerns
No architecture-level concerns identified.

Before / after behavior

  • observed — Modified behavior in demo/casts/atmos.d/screengrabs/cli.yaml: Added the CloudFormation command and eight subcommand help entries to the recording script’s COMMANDS list.

  • observed — Modified behavior in examples/cloudformation/.gitignore: Added the volume/** ignore pattern.
  • observed — Modified behavior in examples/cloudformation/atmos.yaml: Configures the CloudFormation component base path, stack discovery and exclusions, and stage-based stack naming.

…2999)

PR #2999 (osterman/cfn-phase1-core-lifecycle) grew to 154 files, exceeding
CodeRabbit's free-OSS 150-file review cap. Split into a docs-only PR and a
code-only PR (following the same pattern used for #3136/#3137) so both can
receive full automated review.

This commit carries the docs, examples, screengrabs config, and fix-log
entries from #2999, applied on top of #2998 (osterman/cfn-wiring-gap-fixes).

**Bug 1 (primary) — `pkg/component/aws/cloudformation/executor.go`, `runApply` (~line 397-448):**

`result != nil` is a reliable signal for "a direct stack deploy just happened, successfully."

Clarify what a non-nil result proves.

Lines 71–74 say the result is also non-nil for a no-op. It therefore does not prove that a stack deploy happened. State that the direct CloudFormation path returned a result without an error, including the no-op case.

Update the statement about `result != nil` to say it means the direct
CloudFormation path returned a result without an error, including when the
operation was a no-op; do not describe it as proof that a stack deploy occurred.

Path to the CloudFormation template, relative to the component's base
path. Required unless `source.uri` resolves to exactly one file, in which
case Atmos uses that file directly and `template` may be omitted.

Describe template as relative to the component directory.

The example places template.yaml in components/cloudformation/vpc/ and configures template: template.yaml. Line 89 instead says the path is relative to the base path, components/cloudformation. A reader following that rule could set template: vpc/template.yaml, which would not match the example’s component-relative lookup. Use “component directory under the base path,” as in website/docs/cli/configuration/components/aws-cloudformation.mdx.

Update the `template` path description in the CloudFormation component
documentation to say that it is relative to the component directory under the
base path, matching the example’s `template: template.yaml` configuration. Keep
the existing requirement and `source.uri` behavior unchanged.
