Deployment

The whole process is expected to take 60 mins

1. ​

   Configure AWS CLI:

   Install and configure the AWS CLI:
   aws configure
   

2. ​

   Clone this repository:

   git clone https://github.com/langgenius/aws-cdk-for-dify.git
   

3. ​

   Install NodeJS Dependencies:

   npm install
   

4. ​

   Configure environment variables:

   cp .env.example .env
   
   Modify the environment variable values in the .env file.
   • ENVIRONMENT: Specifies the deployment environment; must be either test or prod.
   • CDK_DEFAULT_REGION: The AWS region where Dify Enterprise will be deployed.
   • CDK_DEFAULT_ACCOUNT: Your AWS account ID.
   • DEPLOY_VPC_ID: The ID of an existing VPC for deployment. If not set, CDK will create one for you.
   • Note: If using an existing VPC
     • Make sure you have 2 or more public subnets for Application Load Balancer, and 2 or more private subnets can access internet(associated with NAT) to pull docker image from internet.
     • Add Tag for the subnets(Otherwise, Step 6 will show WARN about auto-tag failed, which will result in the Application Load Balancer failing to be created successfully.):

       Subnet Type	Tag key	tag value
       public	kubernetes.io/role/elb	1
       private	kubernetes.io/role/internal-elb	1

   • Subnets Configuration (DEPLOY_VPC_ID required, comma-separated without spaces, private subnets is recommended by AWS security best practices):
     • EKS_CLUSTER_SUBNETS: Subnet IDs for the EKS control plane. Requires at least 2 subnets in different Availability Zones (AZs).
     • EKS_NODES_SUBNETS: Subnet IDs for the EKS worker nodes. Requires at least 2 subnets in different AZs.
     • REDIS_SUBNETS: Subnet IDs for Redis deployment.
     • RDS_SUBNETS: subnet ids for RDS database. (At least 2 with different AZs)
     • OPENSEARCH_SUBNETS: Subnet IDs for OpenSearch deployment.
     • OPENSEARCH_ADMINNAME: OpenSearch Domain master ame.
     • OPENSEARCH_PASSWORD: OpenSearch Domain master password.
   • AWS_EKS_CHART_REPO_URL: (For AWS China regions ONLY) The AWS EKS Helm chart repository URL.
   • RDS_PUBLIC_ACCESSIBLE: Set to true to make RDS publicly accessible (NOT RECOMMENDED).
   Note:
   • If you are using AWS China regions, you must configure the AWS_EKS_CHART_REPO_URL for proper functionality. Please contact Dify Team for the URL.
   • It is recommended to use an existing VPC for easier resource access.

5. ​

   CDK Bootstrap:

   Initialize the CDK environment:
   npm run init
   

6. ​

   CDK Deploy:

   • Deploy Dify Enterprise:
     npm run deploy
     

7. ​

   Update AWS EKS Access Permissions:

   1. Navigate to the EKS Cluster panel, select the “Access” menu, and click on “Manage access”:
   
   2. In the “Manage access” dialog, select “EKS API and ConfigMap,” then click “Save Changes.”
   3. In the IAM Access Entries panel, click “Create access entry”:
   
   4. Add your IAM user and assign the following permissions:
      • AmazonEKSAdminPolicy
      • AmazonEKSAdminViewPolicy
      • AmazonEKSClusterAdminPolicy

8. ​

   Configure kubeconfig to access the Kubernetes (K8S) cluster locally:

   aws eks update-kubeconfig --region <cn-northwest-1> --name <Dify-Testing-DifyStackTest-EKS>
   
   Adjust the region and name parameters according to your deployment:
   • region: The AWS region where your cluster is deployed.
   • name: The EKS cluster name .

9. ​

   Data Persistence Configure:

   Change the Helm values.yaml file. To enable it, modify the persistence section as follows, replace {your-region-name} and {your-s3-bucket-name} with the name of resource created by CDK, make sure you have turn useAwsManagedIam on:
   persistence:
     type: "s3"
     s3:
       endpoint: "https://s3.{your-region-name}.amazonaws.com"
       region: {your-region-name}
       bucketName: {your-s3-bucket-name}
       useAwsManagedIam: true
   

10. ​

    Database Configure:

    Change the Helm values.yaml file, remove postgre section, and modify the externalPostgres section as follows, replace {your-postgres-endpoint} and {your-postgres-password} with data stored in the Secret Manager of AWS:
    postgre:
      enabled: false
    externalPostgres:
      enabled: true
      address: {your-postgres-endpoint}
      port: 5432
      credentials:
        dify:
          database: "postgres"
          username: "clusteradmin"
          password: {your-postgres-password}
          sslmode: "disable"
        enterprise:
          database: "postgres"
          username: "clusteradmin"
          password: {your-postgres-password}
          sslmode: "disable"
    

11. ​

    Redis Configure:

    Change the Helm values.yaml file, remove redis section, and modify the externalRedis section as follows, replace {your-redis-host} with Primary endpoint in console of ElastiCache-Redis OSS caches Note: remove the port number of the Primary endpoint
    redis:
      enabled: false
    externalRedis:
      enabled: true
      host: "{your-redis-host}"
      port: 6379
      username: ""
      password: ""
      useSSL: false
    

12. ​

    VectorDatabase Configure:

    Change the Helm values.yaml file, modify the externalType section as follows:
    1. replace {openSearch_endpont} with aws Opensearch instant’s Domain endpoint, remove https:// and use the left.
    2. replace the <OPENSEARCH_ADMINNAME> and <OPENSEARCH_PASSWORD> with the value you have set in .env
    vectorDB:
      useExternal: true
      externalType: "opensearch"
      externalOpenSearch:
        host: "{openSearch_endpont}"
        port: 443
        user: "<OPENSEARCH_ADMINNAME>"
        password: "<OPENSEARCH_PASSWORD>"
        useTLS: true
    

13. ​

    Set docker image pull secret

    You need to set the docker image pull secret before installing Dify Enterprise. Note: If you haven’t got the username and password, please contact us, email address:Support@dify.ai

14. ​

    TLS

    ​

    For testing:

    If you are just testing the deploy process, you can just ignore this step and go on.

    ​

    For production:

    Go to AWS ACM to require the certificates of the domain you declared in helm chart configuration file values.yaml:
      consoleApiDomain: "console.xxxx.com"
      consoleWebDomain: "console.xxxx.com"
      serviceApiDomain: "api.xxxx.com"
      appApiDomain: "app.xxxx.com"
      appWebDomain: "app.xxxx.com"
      filesDomain: "upload.xxxx.com"
      enterpriseDomain: "enterprise.xxxx.com"
    
    they are:
    console.xxxx.com
    api.xxxx.com
    app.xxxx.com
    upload.xxxx.com
    enterprise.xxxx.com
    
    go to your domain service provider (e.g. cloud flare, aws route53, etc.) and setup the cname to prove your ownership of these domains. change the values.yaml param: global.useTLS
      useTLS: true
    

15. ​

    AWS Load Balancer Configuration

    It is recommended to use an AWS Application Load Balancer (ALB) for your ingress configuration in the Helm values.yaml file. To enable it, modify the ingress section as follows: For testing:
    ingress:
        enabled: true
        className: "alb"
        annotations: {
            # Existing annotations
            ...
            # Add the following annotations
            alb.ingress.kubernetes.io/target-type: "ip",
            alb.ingress.kubernetes.io/scheme: "internet-facing",
        }
    
    For production: refer to: AWS load balancer controller setup
    ingress:
      enabled: true
      className: "alb"
      annotations: {
        # set file upload size limit
            alb.ingress.kubernetes.io/target-type: "ip",
            alb.ingress.kubernetes.io/scheme: "internet-facing",
            alb.ingress.kubernetes.io/listen-ports: '[{"HTTPS":443}]'
      }
    

16. ​

    Install Dify Enterprise

    Dify Enterprise is deployed using Helm.
    helm repo add dify https://langgenius.github.io/dify-helm
    helm repo update
    
    helm upgrade -i dify -f values.yaml dify/dify
    

17. ​

    Access Dify Enterprise

    ​

    For testing:

    After setting up, get the temperally external IP of the ALB.
    ping {aws_alb_dns}
    
    Then add the following line to your /etc/hosts file.
    4.152.1.216 console.dify.local
    4.152.1.216 app.dify.local
    4.152.1.216 api.dify.local
    4.152.1.216 upload.dify.local
    4.152.1.216 enterprise.dify.local
    

    ​

    For production

    Go to your Domain service provider, and set up DNS to the ALB address(Go to AWS-EC2-Load Balancer to get the dns of alb):

    domain	cname
    api.xxxx.com	<alb_dns>
    app.xxxx.com	<alb_dns>
    upload.xxxx.com	<alb_dns>
    enterprise.xxxx.com	<alb_dns>
    console.xxxx.com	<alb_dns>
