Stacks

Create, update, inspect, and delete CloudFormation stacks.

Validate a template

Check a template for basic syntax and structural validity.

↗#

bashANYawscloudformationtemplate

bash

aws cloudformation validate-template --template-body file://template.yaml

Good preflight check before create or update.

Create a stack

Create a CloudFormation stack from a local template.

↗#

bashANYawscloudformationstackcreate

bash

aws cloudformation create-stack --stack-name app-prod --template-body file://template.yaml --capabilities CAPABILITY_NAMED_IAM

Use `--parameters` for runtime values and acknowledge IAM capability when needed.

Update a stack

Update an existing stack with a new template or parameters.

↗#

bashANYawscloudformationstackupdate

bash

aws cloudformation update-stack --stack-name app-prod --template-body file://template.yaml --capabilities CAPABILITY_NAMED_IAM

Fails with a no-op error if there are no changes.

Deploy a stack with package-style semantics

Create or update a stack using `deploy`.

↗#

bashANYawscloudformationdeploy

bash

aws cloudformation deploy --stack-name app-prod --template-file template.yaml --capabilities CAPABILITY_NAMED_IAM

A very convenient wrapper for common stack deployment workflows.

Describe stacks

Inspect stack status and outputs.

↗#

bashANYawscloudformationstack

bash

aws cloudformation describe-stacks --stack-name app-prod

Useful for checking outputs, status, and rollback information.

Delete a stack

Remove a CloudFormation stack.

↗#

bashANYawscloudformationstackdelete

bash

aws cloudformation delete-stack --stack-name app-prod

Deletes managed resources unless protected or retained.

Wait for stack create complete

Block until a stack finishes creating.

↗#

bashANYawscloudformationwaiter

bash

aws cloudformation wait stack-create-complete --stack-name app-prod

Useful in scripts and CI/CD flows.

Wait for stack update complete

Block until a stack finishes updating.

↗#

bashANYawscloudformationwaiter

bash

aws cloudformation wait stack-update-complete --stack-name app-prod

Lets automation wait for a known-good terminal state.

Change Sets and Events

Preview changes and inspect deployment history.

Create a change set

Preview stack changes before execution.

↗#

bashANYawscloudformationchange-set

bash

aws cloudformation create-change-set --stack-name app-prod --change-set-name preview-001 --template-body file://template.yaml --capabilities CAPABILITY_NAMED_IAM

Useful in controlled production deploy pipelines.

Describe a change set

Inspect the changes proposed for a stack.

↗#

bashANYawscloudformationchange-set

bash

aws cloudformation describe-change-set --stack-name app-prod --change-set-name preview-001

Shows which resources will be added, modified, or replaced.

Execute a change set

Apply the changes in an existing change set.

↗#

bashANYawscloudformationchange-set

bash

aws cloudformation execute-change-set --stack-name app-prod --change-set-name preview-001

Use after reviewing the proposed modifications.

Describe stack events

Read the event history for a stack.

↗#

bashANYawscloudformationevents

bash

aws cloudformation describe-stack-events --stack-name app-prod

Essential for troubleshooting failed creates and updates.

List stack resources

Show resources managed by a stack.

↗#

bashANYawscloudformationresources

bash

aws cloudformation list-stack-resources --stack-name app-prod

Helpful when mapping logical resources to physical IDs.

Get template summary

Return parameter and capability requirements for a template.

↗#

bashANYawscloudformationtemplate

bash

aws cloudformation get-template-summary --template-body file://template.yaml

Useful in tooling that needs to introspect a template before deployment.

Packaging and Artifact Flows

Package local artifacts for deployment-ready templates.

Package local artifacts

Upload local artifacts and rewrite a template.

↗#

bashANYawscloudformationpackage

bash

aws cloudformation package --template-file template.yaml --s3-bucket my-cfn-artifacts --output-template-file packaged.yaml

Useful when templates reference local Lambda zips or nested templates.

Deploy with parameter overrides

Pass parameters at deployment time.

↗#

bashANYawscloudformationdeployparameters

bash

aws cloudformation deploy --stack-name app-prod --template-file packaged.yaml --parameter-overrides Env=prod ImageTag=2026-03-05

Common CI/CD deployment pattern for environment-specific values.

Deploy without failing on empty change set

Treat no-op deployments as success.

↗#

bashANYawscloudformationdeploy

bash

aws cloudformation deploy --stack-name app-prod --template-file packaged.yaml --no-fail-on-empty-changeset

Convenient in pipelines where idempotent deploys are expected.
