Hosting AgentGPT on Linode

Introduction: In a previous blog post, I have already written about the amazing capabilities of AgentGPT. Unfortunately, currently running 10 agents every 3 hours is not feasible due to the high costs for the creators of AgentGPT. Fortunately, there is a solution: you can host AgentGPT yourself! On this Github repo you will find further instructions about the build process.

But since dockerizing an application and then hosting it in the cloud can be quite a challenge if you’re not familiar with Docker, I’ve already done this work for you. On Dockerhub you can find the AgentGPT images in my repo.

In this blog post, I will explain how to dockerize AgentGPT and then host it on Linode, a cloud provider with Kubernetes support.

Linode is a cloud provider known for its reliable and high-performance hosting solutions. You can create an account yourself to follow the steps below.

Steps to Host AgentGPT on Linode

Create a Kubernetes instance on Linode. For this demo, one worker is sufficient, but for production environments, it is recommended to use at least 3 workers. Ensure that the worker has a minimum of 4 CPUs and 8 GB of memory to guarantee optimal performance.

Download the YAML file containing the configuration for the Kubernetes environment. Go to the Kubernetes Dashboard on Linode and log in by uploading the YAML file.

Create a Load Balancer. The Load Balancer ensures that the container we will implement in the next step is publicly accessible. Click on the + symbol in the top right corner and upload the following YAML file to the Linode Kubernetes Dashboard to create the Load Balancer.

apiVersion: v1
kind: Service
metadata:
  name: agentgpt
spec:
  selector:
    app: agentgpt
  ports:
    - port: 80
      targetPort: 3000
  type: LoadBalancer

Once the Load Balancer is created, you can you find the URL where Agent GPT can be accessed later.

Deploy the 3 containers (pods) within Kubernetes by uploading the following YAML file to the Linode Kubernetes Dashboard.

Replace the <base> variable with a random base64 string

Replace the 2 <url> variables with the URL of your load balancer (previous step)

  apiVersion: apps/v1
  kind: Deployment
  metadata:
    name: agentgpt
    labels:
      app: agentgpt
  spec:
    selector:
      matchLabels:
        app: agentgpt
    replicas: 1
    strategy:
      type: Recreate
    template:
      metadata:
        labels:
          app: agentgpt
      spec:
        volumes:
          - name: agentgpt-db
            persistentVolumeClaim:
              claimName: agentgpt-db
        containers:
          - name: agentgpt-next
            image: kerstenremco/agentgpt-next
            resources:
                limits:
                  memory: "2048Mi"
                  cpu: "1"
            ports:
              - containerPort: 3000
            env:
              - name: REWORKD_PLATFORM_HOST
                value: 0.0.0.0
              - name: REWORKD_PLATFORM_DB_HOST
                value: db
              - name: REWORKD_PLATFORM_DB_PORT
                value: "3306"
              - name: REWORKD_PLATFORM_DB_USER
                value: "reworkd_platform"
              - name: REWORKD_PLATFORM_DB_PASS
                value: "reworkd_platform"
              - name: REWORKD_PLATFORM_DB_BASE
                value: "reworkd_platform"
              - name: NEXTAUTH_SECRET
                value: "<base64 string>"
              - name: NEXTAUTH_URL
                value: "<url>"
              - name: NEXT_PUBLIC_BACKEND_URL
                value: "<url>"
              - name: DATABASE_URL
                value: "file:../db/db.sqlite"
          - name: agentgpt-platform
            image: kerstenremco/agentgpt-platform
            resources:
                limits:
                  memory: "4096Mi"
                  cpu: "1"
            ports:
              - containerPort: 8000
          - name: agentgpt-db
            image: kerstenremco/agentgpt-db
            resources:
                limits:
                  memory: "1024Mi"
                  cpu: "1"
            ports:
            command: ["/bin/bash", "-c", "mysqld --initialize && mysqld --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci"]
            ports:
              - containerPort: 3306
            env:
              - name: MYSQL_DATABASE
                value: reworkd_platform
              - name: MYSQL_USERNAME
                value: reworkd_platform
              - name: MYSQL_PASSWORD
                value: reworkd_platform
              - name: MYSQL_ROOT_PASSWORD
                value: reworkd_platform

Wait for a few minutes and check under Pods to see if the pod has a status of running.

Now, open the URL of your Load Balancer, and voila, you have your own AgentGPT at your disposal!

Conclusion

Using Kubernetes on Linode, you can easily host your own instance of AgentGPT. Have fun exploring the capabilities of AgentGPT in your self-hosted environment! 😊

Make sure your AgentGPT instance is protected from unauthorized access my setting network policies. It is also recommended to create a Persistent Volume for the database container which is mapped to /var/lib/mysql/
