atmos aws cloudformation backend create

Create or update the S3 bucket referenced by the component's resolved kind: aws/s3 provision target, applying secure defaults: versioning enabled, AES-256 encryption, and all four public-access-block settings enabled. If the bucket already exists, its settings are brought in line with these defaults rather than left as-is — this operation is idempotent, and can safely be run again.

Experimental

atmos aws cloudformation backend create --help

Usage

atmos aws cloudformation backend create <component> --stack <stack> [options]

atmos aws cloudformation backend create vpc -s plat-ue2-dev

Disambiguate when the component declares more than one kind: aws/s3 target:

atmos aws cloudformation backend create vpc -s plat-ue2-dev --target artifacts

Flags

--stack, -s (required)

Atmos stack.

--target (optional)

The kind: aws/s3 provision target to use. Required when more than one is declared.

--identity, -i (optional)

Atmos identity to authenticate with.

Behavior

backend create resolves the component's stack configuration to find its kind: aws/s3 provision target(s), then provisions the bucket through the same registered S3 backend provisioner atmos terraform backend create uses — no separate backend implementation exists for CloudFormation. If the bucket already existed, a warning explains which existing settings (versioning, encryption, public access, tags) are being overwritten.
