Complete Guide: How to Install Portainer on Ubuntu 22.04 and Manage Docker Easily

Portainer has become one of the most efficient and user-friendly ways to control Docker environments. Instead of memorizing long command-line operations, you can manage containers, images, volumes, and networks from a clean web interface.
In this detailed guide, you will learn how to install Portainer on Ubuntu 22.04, configure it correctly, and start managing Docker containers visually.

Why Use Portainer Instead of Docker CLI

Docker CLI is a robust tool that allows developers to handle everything from container creation to network management. It is fast and flexible but entirely text-based, which can be confusing for beginners and repetitive for advanced users working on large-scale environments.

Portainer provides an intuitive graphical interface on top of Docker. It removes unnecessary complexity and helps teams visualize the state of their containers in real time. With Portainer, you can quickly deploy images, monitor performance, and review logs without typing multiple commands.

For this reason, many administrators choose to install Portainer on Ubuntu to simplify daily container management while maintaining complete control over their Docker infrastructure.

What Is Portainer and Why It Matters

Portainer is an open-source platform that acts as a lightweight management layer for Docker, Docker Swarm, and Kubernetes. It runs itself as a Docker container and provides access to all container-related resources through a web dashboard.

Portainer does not replace Docker but enhances it. After completing a docker install portainer process, you gain the ability to manage your containers, networks, and volumes visually. It is especially useful for system administrators, DevOps engineers, and developers who prefer working in an organized interface.

Versions of Portainer You Can Use

There are two main editions of Portainer:

• Community Edition (CE) – Free and open source, ideal for personal or small business projects.
• Business Edition (BE) – Paid version with advanced features such as Role-Based Access Control, external registry management, and multi-environment connections.

If you only need basic container management, the Community Edition will fully meet your requirements when you install Portainer on Ubuntu 22.04.

Key Benefits of Using Portainer

Once you finish installing Portainer on Ubuntu, you will have access to several practical advantages:

• Manage containers and images from an intuitive web interface.
• Deploy stacks from Docker Compose files directly in your browser.
• Monitor system performance and container logs.
• Connect and manage remote Docker nodes or Kubernetes clusters.
• Simplify network and volume configuration.

This combination of convenience and control makes Portainer one of the best GUI tools available for container management.

What You Need Before You Start?

Before following the installation steps, make sure you have:

1. A system running Ubuntu 22.04.
2. A user with sudo privileges.
3. An active internet connection to download Docker and Portainer images.

Once these requirements are met, you can start the setup process.

Step 1: Update the System Packages

Keeping your system up to date is the first step in any installation. Run the following command:

sudo apt update && sudo apt upgrade -y

This updates the package list and ensures your system is ready for the latest Docker and Portainer versions.

Step 2: Install Docker Engine

Since Portainer itself runs as a Docker container, Docker must be installed first. To install Docker from Ubuntu’s repositories, execute:

sudo apt install docker.io -y

Once installed, enable and start the Docker service:

sudo systemctl enable docker

sudo systemctl start docker

Verify that Docker is running properly:

sudo systemctl status docker

If everything is correct, you will see the status as “active (running).”

Add your user to the Docker group so you can use Docker commands without typing sudo each time:

sudo usermod -aG docker $USER

Open a new terminal session to apply the changes. Your docker install portainer environment is now ready.

Step 3: Install Portainer on Ubuntu

To install Portainer on Ubuntu, pull the latest Portainer image from Docker Hub:

docker pull portainer/portainer-ce:latest

After downloading, confirm the image is available:

docker images

Next, run the Portainer container:

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:latest

Explanation of options:

• -d runs the container in detached mode.
• -p 9000:9000 maps the container’s port to your server’s port.
• --restart always keeps the container running after reboot.
• -v mounts volumes for persistent data.
  
  

To confirm that Portainer is running, use:

docker ps

You should see the Portainer container active and mapped to port 9000.

Step 4: Access the Portainer Web Dashboard

Once Portainer is up, open your browser and go to:

http://your-server-ip:9000

You will be prompted to create an administrator account. Enter a username and a strong password, then click Create User.

After that, you will reach the “Connect to Environment” screen. Choose the Local environment option and click Connect. Portainer will automatically detect the Docker daemon on your system and connect to it.

Now you can manage all Docker resources directly through your web interface.

Step 5: Deploy Your First Container via Portainer

On the Portainer dashboard, select Containers → Add container.
Provide the container name, image name (for example nginx:latest), and port mapping (80:80).

Click Deploy the container to start it.
Within seconds, the new container will appear in your list, running and accessible.

From the dashboard, you can easily:

• Start, stop, restart, or delete containers.
• View logs and inspect resource usage.
• Create networks or volumes visually.
• Pull new images from Docker Hub.
  
  

This step demonstrates the practical value of the install Portainer on Ubuntu process.

Step 6: Secure the Portainer Installation

By default, Portainer runs on HTTP. For production, it is strongly recommended to secure access with HTTPS. You can use a reverse proxy such as Nginx:

sudo apt install nginx -y

Configure Nginx to forward HTTPS requests to Portainer’s port 9000.
Alternatively, mount SSL certificates directly into the Portainer container using volume parameters. This ensures encrypted access for all users.

Step 7: Update or Reinstall Portainer

To keep Portainer updated, pull the newest version and recreate the container:

docker pull portainer/portainer-ce:latest

docker stop portainer

docker rm portainer

Then run the container again with the same command from Step 3.
Your configuration and users will remain intact because they are stored in the portainer_data volume.

If you ever need to perform a clean reinstallation, simply remove that volume before re-deploying.

Step 8: Fixing Common Problems

If Portainer does not load or shows a timeout error, restart the container:

docker restart portainer

If Docker itself becomes unresponsive:

sudo systemctl restart docker

Also, check your firewall and make sure port 9000 is open:

sudo ufw allow 9000/tcp

These steps solve 90% of access and startup issues when installing Portainer on Ubuntu.

Step 9: Automate the Installation Process

For DevOps teams managing multiple servers, automating docker install portainer saves time.
Create a shell script:

#!/bin/bash

sudo apt update -y

sudo apt install docker.io -y

sudo systemctl enable docker --now

docker pull portainer/portainer-ce:latest

docker run -d -p 9000:9000 --restart always \

-v /var/run/docker.sock:/var/run/docker.sock \

-v portainer_data:/data portainer/portainer-ce:latest

Save it as install_portainer.sh, make it executable with chmod +x install_portainer.sh, and run it on any new Ubuntu instance to automate deployment.

Step 10: Connect Portainer to Kubernetes or Swarm

After completing your Install Portainer on Ubuntu setup, you can connect it to Kubernetes or Docker Swarm.
Through the Portainer dashboard, you can visualize clusters, deploy stacks, manage pods, and apply configurations in real time.

This cross-environment functionality makes Portainer a unified platform for managing hybrid container ecosystems without installing multiple tools.

Step 11: Backup and Restore Portainer Data

Portainer stores its data inside the portainer_data volume.
To create a backup:

docker stop portainer

docker run --rm -v portainer_data:/data -v $(pwd):/backup busybox tar czf /backup/portainer_backup.tar.gz /data

To restore from backup:

docker run --rm -v portainer_data:/data -v $(pwd):/backup busybox tar xzf /backup/portainer_backup.tar.gz -C /

Keeping regular backups ensures you can recover configurations quickly after updates or migrations.

Step 12: Verify the Installation

Run the command:

docker ps

You should see Portainer running and mapped to port 9000.
Open your browser at http://your-server-ip:9000 and log in to confirm the dashboard is accessible and showing your containers correctly.

Additional Tips for Stable Performance

These best practices help maintain a clean and reliable container management environment:

1. Custom Port Mapping: Use -p 8080:9000 if port 9000 is already in use.
2. Persistent Storage: Always define named volumes for data retention.
3. Resource Management: Limit CPU and memory usage for each container.
4. Regular Updates: Pull new Portainer images monthly to ensure security.
