Solution Features

The solution is characterized by the following features:

Infrastructure as Code (IaC) Deployment: We employ a minimalist approach to operations and maintenance. Using AWS Cloud Development Kit (AWS CDK) and Amazon EKS Blueprints, we manage the Amazon Elastic Kubernetes Service (Amazon EKS) clusters that host and run ComfyUI.
Dynamic Scaling with Karpenter: Leveraging the capabilities of Karpenter, we customize node scaling strategies to meet business needs.
Cost Savings with Amazon Spot Instances: We utilize Amazon Spot instances to reduce the costs of GPU instances.
Optimized Use of GPU Instance Store: By fully utilizing the instance store of GPU instances, we maximize performance for model loading and switching while minimizing the costs associated with model storage and transfer.
Direct Image Writing with S3 CSI Driver: Images generated are directly written to Amazon S3 using the S3 CSI driver, reducing storage costs.
Accelerated Dynamic Requests with Amazon CloudFront: To facilitate the use of the platform by art studios across different regions, we use Amazon CloudFront for faster dynamic request processing.
Serverless Event-Triggered Model Synchronization: When models are uploaded to or deleted from S3, serverless event triggers activate, syncing the model directory data across worker nodes.

Solution Architecture

The solution's architecture is structured into two distinct phases: the deployment phase and the user interaction phase.

Deployment Phase

Model Storage in S3: ComfyUI's models are stored in S3 for models, following the same directory structure as the native ComfyUI/models directory.
GPU Node Initialization in EKS Cluster: When GPU nodes in the EKS cluster are initiated, they format the local Instance store and synchronize the models from S3 to the local Instance store using user-data scripts.
Running ComfyUI Pods in EKS: Pods operating ComfyUI effectively link the Instance store directory on the node to the pod's internal models directory, facilitating seamless model access and loading.
Model Sync with Lambda Trigger: When models are uploaded to or deleted from S3, a Lambda function is triggered to synchronize the models from S3 to the local Instance store on all GPU nodes via SSM commands.
Output Mapping to S3: Pods running ComfyUI map the ComfyUI/output directory to S3 for outputs with PVC (Persistent Volume Claim) methods.

User Interaction Phase

Request Routing: When a user request reaches the EKS pod through CloudFront --> ALB, the pod first loads the model from the Instance store.
Image Storage Post-Inference: After inference, the pod stores the image in the ComfyUI/output directory, which is directly written to S3 using the S3 CSI driver.
Performance Advantages of Instance Store: Thanks to the performance benefits of the Instance store, the time taken for initial model loading and model switching is significantly reduced.

You can find the deployment code with following address, for detailed deployment instructions, please refer to Section 6.

https://github.com/aws-samples/comfyui-on-eks

Image Generation

Once deployed, you can access and use the ComfyUI frontend directly through a browser by visiting the domain name of CloudFront or the domain name of Kubernetes Ingress.

You can also interact with ComfyUI by saving its workflow as a JSON file that's callable via an API. This method facilitates better integration with your own platforms and systems. For reference on how to make these calls, see the code in comfyui-on-eks/test/invoke_comfyui_api.py.

Deployment Instructions

1. Prerequisites

This solution assumes that you have already installed, deployed, and are familiar with the following tools:

AWS CLI: latest version
eksctl
kubectl
Docker
npm
CDK: 2.147.3

Make sure that you have enough vCPU quota for G instances. (At least 8 vCPU for a g5.2xl/g4dn.2x used in this guidance)

Download the code, checkout the branch, install rpm packages, and check the environment

git clone https://github.com/aws-samples/comfyui-on-eks ~/comfyui-on-eks
cd ~/comfyui-on-eks && git checkout v0.3.0
npm install
npm list
cdk list

Run npm list to ensure following packages are installed

[email protected] ~/comfyui-on-eks
├── @aws-quickstart/[email protected]
├── [email protected]
├── [email protected]
└── ...

Run cdk list to ensure the environment is all set, you will have following CloudFormation stack to deploy

Comfyui-Cluster
CloudFrontEntry
LambdaModelsSync
S3Storage
ComfyuiEcrRepo

2. Deploy EKS Cluster

Run the following command

cd ~/comfyui-on-eks && cdk deploy Comfyui-Cluster

CloudFormation will create a stack named Comfyui-Cluster to deploy all the resources required for the EKS Cluster. This process typically takes around 20 to 30 minutes to complete.

The configuration details for the Comfyui-Cluster Stack can be explored in the file comfyui-on-eks/lib/comfyui-on-eks-stack.ts. Essential elements to focus on are as follows:

The EKS cluster is constructed using the EKS Blueprints framework, blueprints.EksBlueprint.builder().
A selection of Addons from EKS Blueprints are installed for the EKS cluster:
- AwsLoadBalancerControllerAddOn: Manages the Kubernetes ingress ALB.
- SSMAgentAddOn: Enables the use of SSM on EKS nodes for remote login or command execution.
- Karpenter: Facilitates the scaling of EKS nodes.
- GpuOperatorAddon: Supports the operation of GPU nodes.
S3 permissions are added to the EKS nodes to enable the synchronization of model files from S3 to the local instance store.
Rather than specifying a nodegroup for GPU instances, we establish a nodegroup with CPU instances dedicated to lightweight applications, which facilitates the operation of Addon pods. The management and scaling of GPU instances are exclusively handled by Karpenter.

Upon successful deployment, the CDK outputs will present a ConfigCommand. This command is used to update the configuration, enabling access to the EKS cluster via kubectl.

Execute the above ConfigCommand to authorize kubectl to access the EKS cluster

To verify that kubectl has been granted access to the EKS cluster, execute the following command:

kubectl get svc

Now, the deployment of the EKS cluster is complete.

Also, note that EKS Blueprints has outputted KarpenterInstanceNodeRole, which is the role for the nodes managed by Karpenter. Please record this role, as it will be configured in section 5.2.

3. Deploy an S3 bucket for storing models and set up Lambda for dynamic model synchronization

Run the following command:

cd ~/comfyui-on-eks && cdk deploy LambdaModelsSync

The LambdaModelsSync stack primarily creates the following resources:

S3 bucket: The S3 bucket is named following the format comfyui-models-{account_id}-{region}, it's used to store ComfyUI models.
Lambda function, along with its associated role and event source: The Lambda function, named comfy-models-sync, is designed to trigger the synchronization of models from the S3 bucket to local storage on GPU instances whenever models are uploaded to or deleted from S3.

Essential details in the LambdaModelsSync resource configuration, located in comfyui-on-eks/lib/lambda-models-sync.ts, include:

The code for the Lambda function is located in comfyui-on-eks/lib/ComfyModelsSyncLambda/model_sync.py.
The Lambda is used to filter all GPU instances within the ComfyUI EKS Cluster using tags, when create or remove events occur in the S3 bucket storing models, it uses SSM to command all GPU instances to synchronize the models from S3 to their local directories (instance store).

Once the S3 for Models and Lambda are deployed, the S3 bucket will initially be empty. Execute the following command to initialize the S3 bucket and download the SDXL model for testing purposes.

Note: The following command will download the SDXL model to your local machine and upload it to S3. Ensure you have enough disk space (20GB). Alternatively, you can upload the model to the corresponding S3 directory using your preferred method.

region="us-west-2" # Modify the region to your current region.
cd ~/comfyui-on-eks/test/ && bash init_s3_for_models.sh $region

There's no need to wait for the model to finish downloading and uploading to S3. You can proceed with the following steps, just ensure the model is uploaded to S3 before starting the GPU nodes.

4. Deploy S3 bucket for storing inputs to ComfyUI and outputs from ComfyUI

Run the following command

cd ~/comfyui-on-eks && cdk deploy S3Storage

The S3Storage stack just creates two S3 buckets, named following the pattern comfyui-outputs-{account_id}-{region} and comfyui-inputs-{account_id}-{region}, which is used to store inputs and outputs.

5. Deploy ComfyUI Workload

The ComfyUI workload is deployed through Kubernetes. Please follow the steps below.

5.1 Build and Push ComfyUI Docker Image

Run the following command, create an ECR repo for ComfyUI image

cd ~/comfyui-on-eks && cdk deploy ComfyuiEcrRepo

Run the build_and_push.sh script on a machine where Docker has been successfully installed.

region="us-west-2" # Modify the region to your current region.
cd ~/comfyui-on-eks/comfyui_image/ && bash build_and_push.sh $region

For the ComfyUI Docker image, refer to comfyui-on-eks/comfyui_image/Dockerfile, keeping the following points in mind:

The Dockerfile uses a combination of git clone and git checkout to pin a specific version of ComfyUI. Modify this as needed.
The Dockerfile does not install customer nodes, these can be added as needed using the RUN command.
You only need to rebuild the image and replace it with the new version to update ComfyUI.

After building the image, execute the following command to ensure the image's architecture is X86, as the GPU instances used in this solution are all based on X86 models.

region="us-west-2" # Modify the region to your current region.
ACCOUNT_ID=$(aws sts get-caller-identity --query Account --output text)
image_name=${ACCOUNT_ID}.dkr.ecr.${region}.amazonaws.com/comfyui-images:latest
docker image inspect $image_name|grep Architecture

5.2 Deploy Karpenter for Managing GPU Instance Scaling

Get the KarpenterInstanceNodeRole in Section 2 and run the following command to deploy Karpenter:

Run on Linux

KarpenterInstanceNodeRole="Comfyui-Cluster-ComfyuiClusterkarpenternoderoleE627-juyEInBqoNtU" # Modify the role to your own.
sed -i "s/role: KarpenterInstanceNodeRole.*/role: $KarpenterInstanceNodeRole/g" comfyui-on-eks/manifests/Karpenter/karpenter_v1beta1.yaml
kubectl apply -f comfyui-on-eks/manifests/Karpenter/karpenter_v1beta1.yaml

Run on MacOS

KarpenterInstanceNodeRole="Comfyui-Cluster-ComfyuiClusterkarpenternoderoleE627-juyEInBqoNtU" # Modify the role to your own.
sed -i '' "s/role: KarpenterInstanceNodeRole.*/role: $KarpenterInstanceNodeRole/g" comfyui-on-eks/manifests/Karpenter/karpenter_v1beta1.yaml
kubectl apply -f comfyui-on-eks/manifests/Karpenter/karpenter_v1beta1.yaml

To verify the deployment of Karpenter, use this command:

kubectl describe karpenter

Key considerations for Karpenter's deployment:

We use both g5.2xlarge and g4dn.2xlarge instances, along with both on-demand and spot instances.
Initialization of GPU instances launched by Karpenter in userData:
1. Formatting the instance store local disk and mounting it to the /comfyui-models directory.
2. Synchronizing model files stored on S3 to the local instance store.

The KarpenterInstanceNodeRole needs an additional S3 access permission to allow GPU nodes to sync files from S3. Execute the following command:

KarpenterInstanceNodeRole="Comfyui-Cluster-ComfyuiClusterkarpenternoderoleE627-juyEInBqoNtU" # Modify the role to your own.
aws iam attach-role-policy --policy-arn arn:aws:iam::aws:policy/AmazonS3FullAccess --role-name $KarpenterInstanceNodeRole

5.3 Deploy S3 PV and PVC to store generated images

Execute the following command to deploy the PV and PVC for S3 CSI.

Run on Linux

region="us-west-2" # Modify the region to your current region.
account=$(aws sts get-caller-identity --query Account --output text)
sed -i "s/region .*/region $region/g" comfyui-on-eks/manifests/PersistentVolume/sd-outputs-s3.yaml
sed -i "s/bucketName: .*/bucketName: comfyui-outputs-$account-$region/g" comfyui-on-eks/manifests/PersistentVolume/sd-outputs-s3.yaml
sed -i "s/region .*/region $region/g" comfyui-on-eks/manifests/PersistentVolume/sd-inputs-s3.yaml
sed -i "s/bucketName: .*/bucketName: comfyui-inputs-$account-$region/g" comfyui-on-eks/manifests/PersistentVolume/sd-inputs-s3.yaml
kubectl apply -f comfyui-on-eks/manifests/PersistentVolume/

Run on MacOS

region="us-west-2" # Modify the region to your current region.
account=$(aws sts get-caller-identity --query Account --output text)
sed -i '' "s/region .*/region $region/g" comfyui-on-eks/manifests/PersistentVolume/sd-outputs-s3.yaml
sed -i '' "s/bucketName: .*/bucketName: comfyui-outputs-$account-$region/g" comfyui-on-eks/manifests/PersistentVolume/sd-outputs-s3.yaml
sed -i '' "s/region .*/region $region/g" comfyui-on-eks/manifests/PersistentVolume/sd-inputs-s3.yaml
sed -i '' "s/bucketName: .*/bucketName: comfyui-inputs-$account-$region/g" comfyui-on-eks/manifests/PersistentVolume/sd-inputs-s3.yaml
kubectl apply -f comfyui-on-eks/manifests/PersistentVolume/

5.4 Deploy EKS S3 CSI Driver

Run the following command to add your IAM principal to EKS cluster

identity=$(aws sts get-caller-identity --query 'Arn' --output text --no-cli-pager)
if [[ $identity == *"assumed-role"* ]]; then
    role_name=$(echo $identity | cut -d'/' -f2)
    account_id=$(echo $identity | cut -d':' -f5)
    identity="arn:aws:iam::$account_id:role/$role_name"
fi
aws eks update-cluster-config --name Comfyui-Cluster --access-config authenticationMode=API_AND_CONFIG_MAP
aws eks create-access-entry --cluster-name Comfyui-Cluster --principal-arn $identity --type STANDARD --username comfyui-user
aws eks associate-access-policy --cluster-name Comfyui-Cluster --principal-arn $identity --access-scope type=cluster --policy-arn arn:aws:eks::aws:cluster-access-policy/AmazonEKSAdminPolicy

Run the following command to ensure that your IAM principal has been added

aws eks list-access-entries --cluster-name Comfyui-Cluster|grep $identity

Execute the following command to create a role and service account for the S3 CSI driver, enabling it to read and write to S3.

region="us-west-2" # Modify the region to your current region.
account=$(aws sts get-caller-identity --query Account --output text)
ROLE_NAME=EKS-S3-CSI-DriverRole-$account-$region
POLICY_ARN=arn:aws:iam::aws:policy/AmazonS3FullAccess
eksctl create iamserviceaccount \
    --name s3-csi-driver-sa \
    --namespace kube-system \
    --cluster Comfyui-Cluster \
    --attach-policy-arn $POLICY_ARN \
    --approve \
    --role-name $ROLE_NAME \
    --region $region

Run the following command to install aws-mountpoint-s3-csi-driver Addon

region="us-west-2" # Modify the region to your current region.
account=$(aws sts get-caller-identity --query Account --output text)
eksctl create addon --name aws-mountpoint-s3-csi-driver --cluster Comfyui-Cluster --service-account-role-arn "arn:aws:iam::${account}:role/EKS-S3-CSI-DriverRole-${account}-${region}" --force

5.5 Deploy ComfyUI Deployment and Service

Run the following command to replace docker image

Run on Linux

region="us-west-2" # Modify the region to your current region.
account=$(aws sts get-caller-identity --query Account --output text)
sed -i "s/image: .*/image: ${account}.dkr.ecr.${region}.amazonaws.com\/comfyui-images:latest/g" comfyui-on-eks/manifests/ComfyUI/comfyui_deployment.yaml

Run on MacOS

region="us-west-2" # Modify the region to your current region.
account=$(aws sts get-caller-identity --query Account --output text)
sed -i '' "s/image: .*/image: ${account}.dkr.ecr.${region}.amazonaws.com\/comfyui-images:latest/g" comfyui-on-eks/manifests/ComfyUI/comfyui_deployment.yaml

Run the following command to deploy ComfyUI Deployment and Service

kubectl apply -f comfyui-on-eks/manifests/ComfyUI

A few points to note about ComfyUI Deployment and Service:

ComfyUI pod scaling time depends on the instance type, if there are insufficient nodes, Karpenter will need to provision nodes for initialization before pods get scheduled, once images sync, pods become schedulable. You can check Kubernetes events and Karpenter logs with following command:
```
podName=$(kubectl get pods -n karpenter|tail -1|awk '{print $1}')
kubectl logs -f $podName -n karpenter
```
```
kubectl get events --watch
```
If you see ERROR log like following
```
AuthFailure.ServiceLinkedRoleCreationNotPermitted: The provided credentials do not have permission to create the service-linked role for EC2 Spot Instances.
```
You need to create a service linked role
```
aws iam create-service-linked-role --aws-service-name spot.amazonaws.com
```
Different GPU instance types have different Instance Store sizes. If the total model size in S3 exceeds the Instance Store size, you'll need to use other method to manage model storage.

When ComfyUI pod is running, execute the following command to check the log:

podName=$(kubectl get pods |tail -1|awk '{print $1}')
kubectl logs -f $podName

You may encounter error log like this

E0718 16:22:59.734961       1 driver.go:96] GRPC error: rpc error: code = Internal desc = Could not mount "comfyui-outputs-123456789012-us-west-2" at "/var/lib/kubelet/pods/5d662061-4f4b-45

ad /host/proc/mounts: open /host/proc/mounts: invalid argument

It's maybe a bug with Karpenter and mountpoint-s3-csi-driver: Pod "Sometimes" cannot mount PVC in CSI

Currently workaround is just killing the pod s3-csi-node-xxxx to let it restart.

kubectl delete pod s3-csi-node-xxxx -n kube-system # Modify the pod name to your own

6. Test ComfyUI on EKS

6.1 API Test

Test with API, run the following command in the comfyui-on-eks/test directory:

Run on Linux

ingress_address=$(kubectl get ingress|grep comfyui-ingress|awk '{print $4}')
sed -i "s/SERVER_ADDRESS = .*/SERVER_ADDRESS = \"${ingress_address}\"/g" invoke_comfyui_api.py
sed -i "s/SHOW_IMAGES = .*/SHOW_IMAGES = False/g" invoke_comfyui_api.py
./invoke_comfyui_api.py test_workflows/sdxl_refiner_prompt_api.json

Run on MacOS

ingress_address=$(kubectl get ingress|grep comfyui-ingress|awk '{print $4}')
sed -i '' "s/SERVER_ADDRESS = .*/SERVER_ADDRESS = \"${ingress_address}\"/g" invoke_comfyui_api.py
sed -i '' "s/SHOW_IMAGES = .*/SHOW_IMAGES = False/g" invoke_comfyui_api.py
./invoke_comfyui_api.py test_workflows/sdxl_refiner_prompt_api.json

Refer to comfyui-on-eks/test/invoke_comfyui_api.py for the API call logic. Note the following points:

The API call executes the ComfyUI workflow stored in comfyui-on-eks/test/test_workflows/sdxl_refiner_prompt_api.json.
Two models are used: sd_xl_base_1.0.safetensors and sd_xl_refiner_1.0.safetensors.
You can modify the prompt in sdxl_refiner_prompt_api.json or invoke_comfyui_api.py to test different inputs.

6.2 Test with browser

Run the following command to get the K8S ingress address:

kubectl get ingress

Access the ingress address through a web browser.

The deployment and testing of ComfyUI on EKS is now complete. Next we will connect the EKS cluster to CloudFront for edge acceleration.

7. Deploy CloudFront for edge acceleration (Optional)

Execute the following command in the comfyui-on-eks directory to connect the Kubernetes ingress to CloudFront:

cdk deploy CloudFrontEntry

The CloudFrontEntry stack can be referenced in comfyui-on-eks/lib/cloudfront-entry.ts. Pay attention to the following:

The EKS Ingress ALB is found by tag.
The EKS Ingress ALB is set as the CloudFront Distribution origin.
The ComfyUI ALB ingress is only configured for HTTP, so the CloudFront Origin Protocol Policy is set to HTTP_ONLY.
Caching is disabled for dynamic requests by setting the cache policy to CACHING_DISABLED.

After deployment completes, Outputs will be printed including the CloudFront URL CloudFrontEntry.cloudFrontEntryUrl. Refer to section 6.6 for testing via the API or browser.

Delete All Resources

Run the following command to delete all Kubernetes resources:

kubectl delete -f comfyui-on-eks/manifests/ComfyUI/
kubectl delete -f comfyui-on-eks/manifests/PersistentVolume/
kubectl delete -f comfyui-on-eks/manifests/Karpenter/

Run the following command to delete all deployed resources:

aws ecr batch-delete-image --repository-name comfyui-images --image-ids imageTag=latest
cdk destroy ComfyuiEcrRepo
cdk destroy CloudFrontEntry
cdk destroy S3Storage
cdk destroy LambdaModelsSync
cdk destroy Comfyui-Cluster

Cost Analysis

Assuming the following scenario:

Deploying 1 g5.2xlarge instance for image generation
Generating a 1024x1024 image takes average 9 seconds, with average size of 1.5MB
Daily usage time is 8 hours, with 20 days of usage per month
The number of images that can be generated per month is 8 x 20 x 3600 / 9 = 64000
The total size of images to be stored each month is 64000 x 1.5MB / 1000 = 96GB
DTO traffic size is approximately 100GB (96GB + HTTP requests)
ComfyUI images of different versions total 20GB

The total cost of deploying this solution in us-west-2 is approximately $441.878 (using CloudFront for external access) or $442.378 (using ALB for external access)
