Creating an AWS Linux System Running Docker and Managing It with Portainer

Running containers in the cloud doesn’t have to be complicated. In this guide, we’ll walk through creating an AWS EC2 Linux instance, installing Docker, and setting up Portainer to manage containers visually and effortlessly.

By the end, you’ll have a lightweight, production-ready Docker host you can control from your browser.

Prerequisites

Before we begin, make sure you have:

• An AWS account
• Basic familiarity with Linux and SSH
• An EC2 key pair for secure access
• A local machine with SSH installed

Step 1: Launch an AWS EC2 Linux Instance

1. Log in to the AWS Management Console
2. Navigate to EC2 → Launch Instance
3. Choose an AMI:
   • Select Amazon Linux 2 (recommended for stability and AWS compatibility)
4. Choose an instance type:
   • t2.micro or t3.micro (free tier eligible)
5. Configure key settings:
   • Attach your key pair
   • Allow SSH (port 22) in the security group
   • Add port 9000 (Portainer UI) and port 80 if you plan to run web apps
6. Launch the instance 🚀

Once running, copy the public IPv4 address.

Step 2: Connect to the EC2 Instance

From your local terminal:

ssh -i your-key.pem ec2-user@<EC2_PUBLIC_IP>

If successful, you’ll be logged into your Amazon Linux server.

Step 3: Install Docker on Amazon Linux

Update the system:

sudo yum update -y

Install Docker:

sudo amazon-linux-extras install docker -y

Start and enable Docker:

sudo systemctl start docker
sudo systemctl enable docker

(Optional) Allow your user to run Docker without sudo:

sudo usermod -aG docker ec2-user
exit

Reconnect to apply the changes.

Verify installation:

docker --version

Step 4: Run Docker Containers

Test Docker by running a container:

docker run hello-world

If you see the success message, Docker is working correctly 🎉

Step 5: Install Portainer

Portainer gives you a clean web UI to manage containers, images, networks, and volumes.

Create a Docker volume for Portainer

docker volume create portainer_data

Run Portainer

docker run -d \
  -p 9000:9000 \
  --name portainer \
  --restart always \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v portainer_data:/data \
  portainer/portainer-ce

Check that it’s running:

docker ps

Step 6: Access the Portainer Dashboard

Open your browser and go to:

http://<EC2_PUBLIC_IP>:9000

On first launch:

1. Create an admin password
2. Select Docker (local) as the environment
3. Click Connect

You now have full visual control over your Docker host 🎯

What You Can Do with Portainer

With Portainer, you can:

• Deploy containers using forms or Docker Compose
• Monitor container health and logs
• Manage volumes, networks, and images
• Stop, start, or scale services
• Secure access with user roles

It’s perfect for:

• Small production workloads
• Learning Docker visually
• Managing remote servers with ease

Security Best Practices

Before using this in production, consider:

• Restricting port 9000 to your IP only
• Enabling HTTPS with a reverse proxy
• Using IAM roles instead of access keys
• Regularly updating Docker and the OS

Conclusion

By combining AWS EC2, Amazon Linux, Docker, and Portainer, you get a powerful yet simple container platform that scales with your needs. Whether you’re deploying side projects or learning container orchestration, this setup is an excellent foundation.

Happy containerizing 🐳🚀
