From Beginner to Pro: Docker + Terraform for Scalable AI Agents

Introduction

As AI and machine learning workloads grow more complex, developers and DevOps engineers are looking for reliable, reproducible, and scalable ways to deploy them. While tools like Docker and Terraform are widely known, many developers haven’t yet fully unlocked their combined potential, especially when it comes to deploying AI agents or LLMs across cloud or hybrid environments.

This guide walks you through the journey from Docker and Terraform basics to building scalable infrastructure for modern AI/ML systems.

Whether you’re a beginner trying to get your first container up and running or an expert deploying multi-agent LLM setups with GPU-backed infrastructure, this article is for you.

Docker 101: Containerizing Your First AI Model

Let’s start with Docker. Containers make it easier to package and ship your applications. Here’s a quick example of containerizing a PyTorch-based inference model.

Dockerfile:

FROM python:3.9-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt
COPY . .
CMD ["python", "inference.py"]

Build & Run:

docker build -t ai-agent .
docker run -p 5000:5000 ai-agent

You now have a reproducible and portable AI model running in a container!

Terraform 101: Your Infrastructure as Code

Now let’s set up the infrastructure to run this container in the cloud using Terraform.

Basic Terraform Script:

provider "aws" {
  region = "us-east-1"
}

resource "aws_instance" "agent" {
  ami           = "ami-0abcdef1234567890"  # Choose a GPU-compatible AMI
  instance_type = "g4dn.xlarge"

  provisioner "remote-exec" {
    inline = [
      "sudo docker run -d -p 5000:5000 ai-agent"
    ]
  }
}

Deploy:

terraform init
terraform apply

Boom your container is live on an EC2 instance!

Integrating Docker + Terraform: Scalable AI Agent Setup

Now, we combine both tools to:

Auto-provision compute with Terraform
Pull and run your Docker images automatically
Scale agents dynamically by changing Terraform variables

Example:

variable "agent_count" {
  default = 3
}

resource "aws_instance" "agent" {
  count         = var.agent_count
  ami           = "ami-0abc123456"
  instance_type = "g4dn.xlarge"
  ...
}

This lets you spin up multiple Dockerized AI agents across your cloud fleet—perfect for inference APIs or retrieval-augmented generation (RAG) systems.

Advanced Use Case: AI Agents with Multi-GPU, CI/CD & Terraform

Imagine this setup:

Each agent runs an OpenAI-compatible LLM locally (e.g., Mistral, Ollama, LLaMA.cpp)
Terraform provisions GPU instances and networking
Docker builds include prompt routers and memory systems
GitHub Actions auto-triggers Terraform for deployments

Benefits:

Reproducibility across dev, staging, and prod
Cost savings via spot instances
Seamless rollback via Terraform state

This is modern MLOps, containerized.

☁️ Hybrid Multi-Cloud AI with Docker + Terraform

You can even expand this setup to support:

Azure or GCP compute targets
Multi-region failover
Local LLM agents in Docker Swarm clusters (home lab, edge)

Pro Tip: Use Terraform Cloud or Atlantis for remote state and team workflows.

This diagram maps the full lifecycle from writing infrastructure-as-code, containerizing models, and deploying everything automatically.
