Description of your changes

Adds a manually triggered GitHub Actions workflow that invalidates the CloudFront caches after a new CLI release, so users get the new binaries right away instead of stale cached files / someone needs to login in AWS Accounts or need to wait for AWS Account owners.

The workflow uses GitHub OIDC to assume an AWS IAM role. No long-lived AWS access keys are stored in GitHub.

How it works

• Trigger: workflow_dispatch (run it manually after a release).
• Credentials: aws-actions/configure-aws-credentials assumes the role via OIDC.
• Config: one JSON secret maps each distribution ID to the paths to invalidate:

  {
    "TEST123": ["/stable/current/*"]
  }

• The workflow validates the config, creates all invalidations, then waits until every one is completed. Results show up in the job summary.

Security

• Trust policy: the role can only be assumed by repo:crossplane/cli:ref:refs/heads/main with audience sts.amazonaws.com. Forks, other repos, and other branches can't get credentials.
• Permissions: the role only has cloudfront:CreateInvalidation, GetInvalidation and ListInvalidations, scoped to the listed distribution ARNs.
• Job guard: the job only runs on main in this repo, so forks skip it.
• Token permissions: the GITHUB_TOKEN gets only id-token: write.

AWS setup (already done)

• GitHub OIDC identity provider created in the AWS account.
• IAM role gha-cloudfront-invalidator-crossplane-cli created with the trust policy and scoped permissions above.

ToDo after merge

• Create repo secret AWS_ROLE_ARN
• Create repo secret CLOUDFRONT_INVALIDATIONS (JSON as above + real distribution id)
• Run the workflow once from main to verify

📝 Walkthrough

This change adds a manually triggered GitHub Actions workflow that validates CloudFront invalidation configuration, assumes an AWS role through OIDC, creates invalidations, and waits for them to complete.

Changes: CloudFront invalidation

Layer / File(s)	Summary
Workflow setup and configuration validation .github/workflows/cloudfront.yaml	The workflow runs manually for the configured repository and main branch. It validates the distribution IDs and invalidation paths, and fails for invalid configuration.
AWS authentication and invalidation creation .github/workflows/cloudfront.yaml	The workflow assumes the configured AWS role through OIDC and creates an invalidation for each configured distribution.
Completion checks and job summary .github/workflows/cloudfront.yaml	The workflow waits for each invalidation to complete and adds a success entry to the job summary.

Merge Risk: 🟡 Moderate · up to 3be4c

The new CloudFront invalidation workflow will never run in this repository because its repository check names the wrong repository, so caches will not be refreshed after a CLI release. Correct the repository name before merging. Separately, a slow invalidation can make the run report failure even though CloudFront may still complete it.

Explanation

PASS. The pull request adds only .github/workflows/cloudfront.yaml, a manually triggered CI workflow. It does not change apis/**, add an experimental product feature, or introduce application behavior that requires a feature flag.

Review comments at @.github/workflows/cloudfront.yaml:
- Line 59: Replace the fixed-retry `aws cloudfront wait invalidation-completed`
call with polling that checks the invalidation status until it completes or an
explicit deadline within the job’s 30-minute timeout is reached; preserve
failure reporting when the deadline expires.
- Line 15: Update the repository comparison in the invalidate job’s `if` guard
to use `crossplane/cli` instead of `crossplane/crossplane-cli`, preserving the
`main` branch condition.
