StackState SaaS

Overview

Amazon Web Services (AWS) is a major cloud provider. This StackPack enables in-depth monitoring of AWS services.

Data flow

• StackState Agent V2 collects all service responses from the target AWS account.

• Topology is updated in real time:

  • Once an hour, all services are queried to gain a full point-in-time snapshot of resources.

  • Once a minute, Cloudtrail and Eventbridge events are read to find changes to resources.

• Logs are retrieved once a minute from CloudWatch and a central S3 bucket. These are mapped to associated components in StackState.

• Metrics are retrieved on-demand by the StackState CloudWatch plugin. These are mapped to associated components in StackState.

• VPC FlowLogs are retrieved once a minute from the configured S3 bucket. Private network traffic inside VPCs is analysed to create relations between EC2 and RDS database components in StackState.

• Communication between NodeJS Lambda functions and the AWS services that they communicate with is monitored using OpenTelemetry traces.

Setup

Prerequisites

To set up the StackState AWS integration, you need to have:

• StackState Agent V2 installed on a machine which can connect to both AWS and StackState.

• AWS CLI version 2.0.4 or later is installed on the environment where StackState is running.

• The following AWS accounts:

  • At least one target AWS account that will be monitored.

  • An AWS account for StackState and the StackState Agent to use when retrieving data from the target AWS account(s). It is recommended to use a separate shared account for this and not use any of the accounts that will be monitored by StackState, but this is not required.

  • A user or role with a policy attached that contains the action to allow assuming the role stsIntegrationRole in the account that will be monitored. For details see the StackState docs on the required AWS policy.

AWS accounts

It is recommended to have two different AWS accounts: One that is being monitored and another used for data collection.

• Monitor Account - used to deploy a CloudFormation Stack. The CloudFormation stack will create an IAM role that has the permissions required to retrieve data from this Monitor Account (StackStateAwsIntegrationRole).

• Data Collection Account - used by StackState and StackState Agent to retrieve data from the Monitor Account. An AWS policy granting permissions to assume the role StackStateAwsIntegrationRole in the Monitor Account is required.

AWS policy

The policy below grants permission to assume the role StackStateAwsIntegrationRole that is created in each target AWS Monitor Account when the CloudFormation Stack is deployed. This policy is required by StackState and StackState Agent to collect data from the AWS Monitor Account. The policy should be created and attached to the AWS user(s) or IAM role(s) that will be used by StackState and the StackState Agent:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "sts:AssumeRole",
      "Resource": "arn:aws:iam::*:role/StackStateAwsIntegrationRole"
    }
  ]
}

The policy can be made available to StackState and the StackState Agent in one of the following ways:

• If StackState and/or StackState Agent run on EC2 or EKS AND the Data Collection Account and Monitor Account are in the same AWS organization:

  • Attach an IAM role to the EC2 instance or EKS pod.

• In all other situations:

  • StackState: Attach the policy to the user configured when the AWS StackPack instance is installed.

  • StackState Agent: Attach the policy to the user configured in the Agent AWS check.

IAM role on EC2 or EKS

StackState Agent collects topology, logs and (if configured) VPC flow logs, and StackState pulls CloudWatch metrics from AWS. If StackState Agent and/or StackState run in an AWS environment and the Data Collection Account and Monitor Account are in the same AWS organization, an IAM role can be attached to the EC2 instance or EKS pod that they run on and used for authentication. This removes the need to specify an AWS Access Key ID and Secret when a StackPack instance is installed or in the Agent AWS check configuration.

Note: The AWS Data Collection Account and Monitor Account must be a part of the same AWS organization to be able to authenticate using an IAM role in this way. For details, see the AWS documentation on AWS organizations (docs.aws.amazon.com).

To attach an IAM role and use it for authentication:

1. If you did not already do so, in AWS, create the required AWS policy.

2. Attach the created policy to the relevant IAM role:

   • StackState/Agent running on EC2

   • StackState/Agent running on EKS

3. To use the IAM role for StackState (CloudWatch metrics): When you install an AWS StackPack instance, set the following parameter values:

   • AWS Access Key ID: use-role

   • AWS Secret Access Key: use-role

4. To use the IAM role for StackState Agent:

   • Agent on EC2: When you configure the AWS check, leave empty quotes for the parameters aws_access_key_id and aws_secret_access_key.

   • Agent on EKS: When you configure the AWS check as a cluster check (required for an Agent running on Kubernetes), leave empty quotes for the parameters aws_access_key_id and aws_secret_access_key in the values.yaml file used to deploy the Cluster Agent.

Deploy the AWS CloudFormation Stack

The StackState AWS CloudFormation Stack should be deployed in each AWS account that you will monitor. It provides the minimum level of access required for StackState and the StackState Agent to collect topology, telemetry and logs.

• Quick deployment - Deploy all resources to a region in an account using a link.

• StackState CloudFormation template - Download the StackState CloudFormation template to integrate into your own deployment workflow.

For special environments where the CloudFormation template may not function correctly, advanced AWS users can refer to the required AWS resources for a reference on all resources that must be manually created..

It is recommended to use the StackState CloudFormation template wherever possible as this provides an easy upgrade path for future versions and reduces the maintenance burden.

Quick deployment

The necessary resources can be deployed for one account in a single region using an automated CloudFormation template.

The table below includes links to deploy the template in popular AWS regions. For any regions not listed, follow the steps described for the StackState template deployment.

• To use OpenTelemetry Traces, set the IncludeOpenTelemetryTracing value to true.

• You must be logged in to the target AWS account in the web console.

Region Name	Template deployment link
Ireland	eu-west-1 (console.aws.amazon.com)
Frankfurt	eu-central-1 (console.aws.amazon.com)
N. Virginia	us-east-1 (console.aws.amazon.com)
Ohio	us-east-2 (console.aws.amazon.com)
N. California	us-west-1 (console.aws.amazon.com)
Hong Kong	ap-east-1 (console.aws.amazon.com)
Singapore	ap-southeast-1 (console.aws.amazon.com)
Sydney	ap-southeast-2 (console.aws.amazon.com)

StackState template deployment

The default StackState CloudFormation template can be used to deploy all necessary resources. It can be deployed to multiple AWS accounts and regions at once by deploying it in a CloudFormation StackSet. It is recommended to use this template as it provides an easy upgrade path for future versions and reduces the maintenance burden compared to creating a custom template.

• Download the default StackState CloudFormation template (stackstate-integrations-resources-eu-west-1.s3.eu-west-1.amazonaws.com)

The template requires the following parameters:

• MainRegion - The primary AWS region. This can be any region, as long as this region is the same for every template deployed within the AWS account. Global resources will be deployed in this region such as the IAM role and S3 bucket. Example: us-east-1.

• StsAccountId - The 12-digit AWS account ID that is going to be monitored. This will be the AWS account that the IAM role can be assumed from, to perform actions on the target AWS account. Example: 0123456789012.

• ExternalId - A shared secret that the StackState Agent will present when assuming a role. Use the same value across all AWS accounts that the Agent is monitoring. Example: uniquesecret!1.

• IncludeOpenTelemetryTracing - Default: disabled. Set to enabled to include the OpenTelemetry layer in your deployment. This is required to retrieve OpenTelemetry traces from AWS Lambda scripts running NodeJS.

• Post fix - Optional. Value to append to all resource names when deploying the stack multiple times in the same account.

For more information on how to use StackSets, check the AWS documentation on working with AWS CloudFormation StackSets (docs.aws.amazon.com).

Install the AWS StackPack

Install the AWS StackPack from the StackState UI StackPacks > Integrations screen. You will need to provide the following parameters, these will be used by StackState to configure the StackPack instance within StackState and query live telemetry from the AWS account. To create topology in StackState, you will also need to configure the AWS check on StackState Agent V2.

• Role ARN - the ARN of the IAM Role created by the cloudFormation stack. For example, arn:aws:iam::<account id>:role/StackStateAwsIntegrationRole where <account id> is the 12-digit AWS account ID that is being monitored.

• External ID - a shared secret that StackState will present when assuming a role. Use the same value across all AWS accounts. For example, uniquesecret!1

• AWS Access Key ID - The Access Key ID of the IAM user that will be used by StackState to collect CloudWatch metrics. This is the same as the IAM user used by the Agent to collect topology data and logs from AWS. If StackState is running within AWS, it may also be possible to authenticate with an IAM role.

• AWS Secret Access Key - The Secret Access Key of the IAM user that will be used by StackState to collect CloudWatch metrics. This is the same as the IAM user used by the Agent to collect topology data and logs from AWS. If StackState is running within AWS, it may also be possible to authenticate with an IAM role.

Configure the AWS check

To enable the AWS check and begin collecting topology and log data from AWS, add the configuration below to StackState Agent V2.

Agent on Kubernetes

If StackState Agent is running on Kubernetes, the AWS check should be configured as a cluster check.

1. If you do not already have it, you will need to add the StackState helm repository to the local helm client:

    helm repo add stackstate https://helm.stackstate.io
    helm repo update

2. Update the values.yaml file used to deploy the stackstate-agent with details of your AWS instance:

   • aws_access_key_id - The AWS Access Key ID. Leave empty quotes to use an attached IAM role.

   • aws_secret_access_key - The AWS Secret Access Key. Leave empty quotes to use an attached IAM role.

   • external_id - The same external ID used to create the CloudFormation stack in every account and region.

   • role_arn - In the example arn:aws:iam::123456789012:role/StackStateAwsIntegrationRole, substitute 123456789012 with the target AWS account ID to read.

   • regions - The Agent will only attempt to find resources in the specified regions. global is a special region for global resources, such as Route53.

   clusterAgent:
     config:
       override:
   #clusterAgent.config.override -- Defines kubernetes_state check for checksAgent agents. Auto-discovery
   #with ad_identifiers does not work here. Use a specific URL instead.
       - name: conf.yaml
         path: /etc/stackstate-agent/conf.d/aws_topology.d
         data: |
           cluster_check: true
   
           init_config:
             aws_access_key_id: ''
             aws_secret_access_key: ''
             external_id: uniquesecret!1 
             # full_run_interval: 3600
   
           instances:
           - role_arn: arn:aws:iam::123456789012:role/StackStateAwsIntegrationRole
               regions:
               - global
               - eu-west-1
               collection_interval: 60 # The amount of time in seconds between each scan. Decreasing this value will not appreciably increase topology update speed.
               # apis_to_run:
               #   - ec2
               # log_bucket_name: '' 
               # tags:
               #   - foo:bar

3. Deploy the checks_agent using the updated values.yaml:

   • Kubernetes:

   helm upgrade --install \
   --namespace stackstate \
   --create-namespace \
   --set-string 'stackstate.apiKey'='<STACKSTATE_RECEIVER_API_KEY>' \
   --set-string 'stackstate.cluster.name'='<KUBERNETES_CLUSTER_NAME>' \
   --set-string 'stackstate.cluster.authToken=<CLUSTER_AUTH_TOKEN>' \
   --set-string 'stackstate.url'='<STACKSTATE_RECEIVER_API_ADDRESS>' \
   --values values.yaml \
   stackstate-agent stackstate/stackstate-agent    

   • OpenShift:

   helm upgrade --install \
   --namespace stackstate \
   --create-namespace \
   --set-string 'stackstate.apiKey'='<STACKSTATE_RECEIVER_API_KEY>' \
   --set-string 'stackstate.cluster.name'='<OPENSHIFT_CLUSTER_NAME>' \
   --set-string 'stackstate.cluster.authToken=<CLUSTER_AUTH_TOKEN>' \
   --set-string 'stackstate.url'='<STACKSTATE_RECEIVER_API_ADDRESS>' \
   --set 'agent.scc.enabled'=true \
   --set 'kube-state-metrics.securityContext.enabled'=false \
   --values values.yaml \
   stackstate-agent stackstate/stackstate-agent    

Agent on Linux VM

If StackState Agent is running on a Linux VM:

1. Edit the Agent integration configuration file /etc/stackstate-agent/conf.d/aws_topology.d/conf.yaml to include details of your AWS instances:

   • aws_access_key_id - The AWS Access Key ID. Leave empty quotes to use an attached IAM role.

   • aws_secret_access_key - The AWS Secret Access Key. Leave empty quotes to use an attached IAM role.

   • external_id - The same external ID used to create the CloudFormation stack in every account and region.

   • role_arn - In the example arn:aws:iam::123456789012:role/StackStateAwsIntegrationRole, substitute 123456789012 with the target AWS account ID to read.

   • regions - The Agent will only attempt to find resources in the specified regions. global is a special region for global resources, such as Route53.

   # values in init_config are used globally; 
   # these credentials will be used for all AWS accounts
   init_config:
     aws_access_key_id: ''
     aws_secret_access_key: ''
     external_id: uniquesecret!1 
     # full_run_interval: 3600
   
   instances:
     - role_arn: arn:aws:iam::123456789012:role/StackStateAwsIntegrationRole
       regions:
         - global # a special "region" used for global resources
         - eu-west-1
       # min_collection_interval: 60 # use in place of collection_interval for Agent V2.14.x or earlier 
       collection_interval: 60 # The amount of time in seconds between each scan. Decreasing this value will not appreciably increase topology update speed.
       # apis_to_run:
       #   - ec2
       # log_bucket_name: '' 
       # tags:
       #   - foo:bar

2. You can also add optional configuration and filters:

   • full_run_interval - Optional. The time in seconds between a full AWS topology scan. Intermediate runs only fetch events.

   • collection_interval - The amount of time in seconds between each scan. Decreasing this value will not appreciably increase topology update speed.

   • apis_to_run - Optionally whitelist specific AWS services. It is not recommended to set this; instead rely on IAM permissions.

   • log_bucket_name - The S3 bucket that the agent should read events from. This value should only be set in custom implementations.

   • tags - Optional. Can be used to apply specific tags to all reported data in StackState.

3. Restart the StackState Agent to apply the configuration changes.

4. Once the Agent has restarted, wait for data to be collected from AWS and sent to StackState.

Configure VPC FlowLogs

VPC FlowLogs can be analysed to retrieve relations between EC2 instances and RDS database instances. For each VPC that you want to analyse, a FlowLog needs to be configured. The process of adding FlowLogs for new VPCs could be automated using a Lambda triggered by a CloudTrail event that creates the FlowLog. Relations will be retrieved for EC2 instances and RDS database instances with a static public or private IP address and emit the proper URNs. For public IP addresses urn:host:/{ip-address}, for private IP addresses the URN has the form urn:vpcip:{vpc-id}/{ip-address}.

For further details, see Required AWS resources - VPC FlowLogs.

To configure a VPC FlowLog from the AWS console:

1. From the VPC Dashboard, choose Your VPCs under VIRTUAL PRIVATE CLOUD.

2. Select the VPC that you want to configure.

3. Select Flow logs on the lower TAB-bar.

4. Click Create flow log.

5. Add the settings as shown in the screenshot.

VPC FlowLog settings

Use an HTTP proxy

Access to the internet is required to call the AWS APIs. If StackState or the StackState Agent cannot be given direct internet access, an HTTP proxy can be used to proxy the API calls.

In the StackState AWS integration, CloudWatch metrics are pulled directly by StackState, while events and topology data are collected by the StackState Agent. This means that proxy details must be configured in two places to handle all requests - StackState for CloudWatch metrics and StackState Agent for topology and events data.

• To configure a proxy for events and topology data collected by StackState Agent, see how to use an HTTP/HTTPS proxy for StackState Agent.

• To configure a proxy for CloudWatch metrics collected by StackState, follow the steps below:

  1. In the StackState UI, go to Settings > Telemetry Sources > CloudWatch sources.

  2. Find the CloudWatch source for which you want to configure a proxy. Open the ... menu to the right and select Edit.

  3. Enter the proxy details in Proxy URI.

  4. Click TEST CONNECTION to check that the proxy can be used to successfully connect to CloudWatch.

  5. Click UPDATE to save the proxy settings. Be aware that you may need to unlock it before this succeeds.

Status

To check the status of the AWS integration, run the status subcommand and look for aws_topology under Running Checks:

sudo stackstate-agent status

Integration details

Data retrieved

The AWS integration retrieves the following data:

• Events

• Metrics

• Topology

• Traces

Events

The AWS StackPack supports the following event:

• EC2 Instance Run State: when the instance is started, stopped, or terminated. This will appear as the Run State in the EC2 instance component.

AWS events are primarily used to provide real-time updates to topology. These events are not displayed as StackState events.

Metrics

Metrics data is pulled at a configured interval directly from AWS by the StackState CloudWatch plugin. Retrieved metrics are mapped onto the associated topology component.

Topology

The AWS service data shown below is available in StackState as components with the associated relations. The retrieved topology can be further enhanced by enabling OpenTelemetry traces.

• * "All Supported Resources" - relations will be made to any other resource on this list, should the resource type support it.

• ** This relation is made by finding valid URIs in the environment variables of the resource. For example, the DNS hostname of an RDS instance will create a relation.

Traces

OpenTelemetry creates traces from the AWS services that your Lambdas interacts with. Retrieved traces are available in the Traces Perspective and are also used to enhance the retrieved topology.

➡️ Learn more about how to set up and use OpenTelemetry

Required AWS resources

A high-level of overview of all resources necessary to run the StackState Agent with full capabilities is provided in the graph below. Users with intermediate to high level AWS skills can use these details to set up the StackState Agent resources manually. For the majority of installations, this is not the recommended approach. Use the provided StackState CloudFormation template unless there are environment-specific issues that must be worked around.

Account components

Hourly and event-based updates collect data:

• Hourly full topology updates - collected by the StackState Agent using an IAM role with access to the AWS services.

• Event-based updates for single components and relations - captured using AWS services and placed into an S3 bucket for the StackState Agent to read.

If the StackState Agent does not have permission to access a certain component, it will skip it.

StackState Agent IAM Role

The bare minimum necessary to run the StackState Agent is an IAM role with necessary permissions. The Agent will always attempt to fetch as much data as possible for the supported resources. If a permission is omitted, the Agent will attempt to create a component with the data it has.

For example, if the permission s3:GetBucketTagging is omitted, the Agent will fetch all S3 buckets and their associated configuration, but the tags section will be empty.

• IAM policy with all required permissions - JSON object

IAM is a global service. Only one IAM role is necessary per account.

S3 Bucket

Once the Agent has finished reading a file in this bucket, the file will be deleted. Do not use an existing bucket for this, the Agent should have its own bucket to read from. The S3 bucket will not be read from if it does not have bucket versioning enabled, to protect data.

The S3 bucket is used to store all incoming events from EventBridge and other event-based sources. The Agent then reads objects from this bucket. These events are used to provide features such as real-time topology updates, and creating relations between components based on event data such as VPC FlowLogs. If the S3 bucket is not available to the Agent it will fall back to reading CloudTrail directly, which introduces a 15-minute delay in real-time updates. EventBridge events and VPC FlowLogs are only available via the S3 bucket.

Only one S3 bucket is necessary per account; all regions can send to the same bucket.

EventBridge Rule

A catch-all rule for listening to all events for services supported by the AWS StackPack. All matched rules are sent to a Kinesis Firehose delivery stream.

• EventBridge Rule - JSON object

• EventBridge IAM Role - JSON - Give permission for EventBridge to send data to Kinesis Firehose

A rule must be created in each region where events are captured, each sending to a Firehose delivery stream in the same region.

Kinesis Firehose

Kinesis Firehose is used to receive and batch events from EventBridge. This delivery stream batches events per 60 seconds and pushes an object to S3. 60 seconds is the recommended value - setting this value any higher will negligibly decrease storage costs while increasing the delay in topology updates.

The Prefix must be set to AWSLogs/${AccountId}/EventBridge/${Region}/, where ${AccountId} and ${Region} are the account ID and region, for example, eu-west-1. Files must be compressed using the GZIP option.

A delivery stream must be created in each region where events are captured, however, the target S3 bucket can exist in any region.

• Kinesis Firehose IAM Role - JSON - Gives permission for Firehose to send data to an S3 bucket.

KMS Key (Optional)

A KMS Customer Managed Key (CMK) can be used to secure data at rest in S3. The KMS key is used in the Firehose Delivery Stream. The S3 bucket also uses the KMS key as its default key.

Use of a KMS is key is not necessary for the operation of the StackPack, however as encryption at rest is a requirement in most environments, the CloudFormation template includes this by default.

A KMS key must be created in each region where events are captured.

• Sample KMS Key policy.

VPC FlowLogs

VPC FlowLogs support is currently experimental.

A VPC configured to send flow logs to the stackstate-logs-${AccountId} S3 bucket. The Agent requires the AWS default format for VPC FlowLogs, and expects data to be aggregated every 1 minute. The FlowLogs contain meta information about the network traffic inside VPCs. Only private network traffic is considered, traffic from NAT gateways and application load balancers will be ignored.

S3 objects that have been processed will be deleted from the bucket to make sure they will not be processed again. On the default S3 bucket, object versioning is enabled, this means objects will not actually be immediately deleted. A lifecycle configuration will expire (delete) both current and non-current object versions after one day. When using a non default bucket, you can set these expiry periods differently.

If configuring FlowLogs using CloudFormation, the stackstate-resources template exports the ARN of the S3 bucket it creates, so this can be imported into your template.

A FlowLog must be configured for each VPC that you want to analyse.

• AWS Flow Logs documentation

Costs

The AWS StackPack CloudFormation template contains all resources that are necessary to run the AWS check on the StackState Agent. The installed resources are kept as minimal as possible. All costs incurred are minimal but variable, with costs scaling depending on how many events are emitted in a given account. In practice, the costs created by the AWS integration will be negligible.

• Kinesis Firehose: priced by the amount of data processed. Events use very small amounts of data. Firehose pricing (aws.amazon.com)

• S3: priced by amount of data stored, and amount of data transferred. Running the Agent inside of AWS will reduce data transfer costs. S3 pricing (aws.amazon.com)

• KMS: a flat fee of $1 per month per key, with additional costs per request. KMS pricing (aws.amazon.com)

• CloudWatch metrics: priced per metric retrived. Metrics are only retrieved when viewed or when a check is configured on a CloudWatch metric. CloudWatch pricing (aws.amazon.com)

AWS views in StackState

When the AWS integration is enabled, three views will be created in StackState for each instance of the StackPack.

• AWS - [instance_name] - All - includes all resources retrieved from AWS by the StackPack instance.

• AWS - [instance_name] - Infrastructure - includes only Networking, Storage and Machines resources retrieved from AWS by the StackPack instance.

• AWS - [instance_name] - Serverless - includes only S3 buckets, lambdas and application load balancers retrieved from AWS by the StackPack instance.

AWS actions in StackState

Components retrieved from AWS will have an additional Action available in the component context menu and in the right panel details tab - Component details - when the component is selected. This provides a deep link through to the relevant AWS console at the correct point.

For example, in the StackState Topology Perspective:

• Components of type aws-subnet have the action Go to Subnet console, which links directly to this component in the AWS Subnet console.

• Components of type ec2-instance have the action Go to EC2 console, which links directly to this component in the EC2 console.

Tags and labels

Tags added as labels in StackState

The following labels will be added to imported AWS topology in StackState:

• stackpack:aws-v2

• All tags that exist for the imported element in AWS.

• All tags specified for the associated instance in the Agent AWS check configuration. You can add a custom label to all topology imported by an instance of the AWS StackPack by adding it to the Agent AWS check configuration.

StackState Self-Hosted

Extra information for the StackState Self-Hosted product:

AWS tags used to build StackState topology

The special tags listed below can be added in AWS to influence how the imported topology is built in StackState:

• stackstate-identifier - The specified value will be added as an identifier to the StackState component.

• stackstate-environment - The StackState component will be placed in the specified environment.

   3. In the top right of the console, select Delete.

AWS CLI

The steps below assume that you already have the AWS CLI installed and configured with access to the target account. If not, follow the AWS documentation to install and configure the AWS CLI (docs.aws.amazon.com).

To delete the StackState AWS Cloudformation stack from an AWS account using the AWS CLI:

1. Set the region to remove StackState resources from:

   REGION="<region>"

2. Set the S3 bucket that will be deleted:

    BUCKET=$(aws cloudformation describe-stack-resource \
      --region $REGION \
      --stack-name stackstate-resources \
      --logical-resource-id StsLogsBucket \
      --query "StackResourceDetail.PhysicalResourceId" \
      --output=text) && echo "Found Bucket: ${BUCKET}"

3. Disable the EventBridge rule:

    aws events disable-rule \
        --region $REGION \
        --name "$(aws cloudformation describe-stack-resource \
            --stack-name stackstate-resources \
            --logical-resource-id StsEventBridgeRule \
            --region $REGION \
            --query "StackResourceDetail.PhysicalResourceId" \
            --output=text)"

4. Delete all FlowLogs that send to this bucket:

    aws ec2 delete-flow-logs \
        --region $REGION \
        --flow-log-ids "$(aws ec2 describe-flow-logs \
            --region $REGION \
            --query "FlowLogs[?LogDestination=='arn:aws:s3:::$BUCKET'].[FlowLogId]" \
            --output=text | tr '\n' ' ')"

5. Delete objects in the S3 bucket. This is a versioned S3 bucket, so each object version will be deleted individually. Note that if there are more than 1000 items in the bucket this command will fail, it's likely more convenient to perform this in the AWS web console:

    sleep 60 # To make sure all objects have finished writing to bucket
    aws s3api delete-objects \
        --region $REGION \
        --bucket "$BUCKET" \
        --delete "$(aws s3api list-object-versions \
            --region $REGION \
            --bucket "$BUCKET" \
            --output=json \
            --query='{Objects: Versions[].{Key:Key,VersionId:VersionId}}')" \
        --output=text

6. Delete the CloudFormation template:

    aws cloudformation delete-stack --region $REGION \
        --stack-name stackstate-resources
