Installing Portainer to the Raspberry Pi?

Portainer is an open-source container management tool that allows you to easily manage Docker containers and services. With its simple and intuitive web-based user interface, Portainer makes Docker container deployment accessible for beginners while still providing advanced features for power users.

Installing Portainer to the Raspberry Pi?

In this comprehensive guide, we will cover installing Portainer to a Raspberry Pi. Using Portainer on the Raspberry Pi enables you to take advantage of lightweight Docker containers to run a variety of apps and services on your Pi. We will cover the entire installation process step-by-step, as well as optimizing Portainer for the Raspberry Pi hardware.

Hardware Requirements

Installing Portainer to your Raspberry Pi requires the following:

  • Raspberry Pi board. Any modern Raspberry Pi board should work, but we recommend Raspberry Pi 4 for the best performance.
  • MicroSD card with Raspberry Pi OS installed. We recommend at least a 16GB card.
  • Power supply for your Pi.
  • Network connection via Ethernet or WiFi.

The Raspberry Pi hardware should be fully setup with Raspberry Pi OS before proceeding with the Portainer install.

Installing Docker on Raspberry Pi

Since Portainer relies on Docker, we first need to install the Docker engine on the Raspberry Pi.

Run the following commands on your Pi to install Docker:

curl -sSL | sh

sudo usermod -aG docker pi

Once Docker is installed, reboot your Raspberry Pi. This ensures the correct permissions are set for managing Docker as a non-root user:

sudo reboot

After your Pi reboots, verify the Docker installation was successful:

docker version

You should see output with the Docker version and relevant component versions, indicating Docker is installed properly.

Deploying Portainer to Raspberry Pi

With Docker set up on the Raspberry Pi, we can proceed to deploying a Portainer container.

Run the following command to deploy a Portainer instance to your Pi:

docker volume create portainer_data

docker run -d -p 8000:8000 -p 9000:9000 –name=portainer –restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:latest

This runs Portainer in detached mode in a Docker container, exposing port 9000 and 8000 while persisting Portainer data to a Docker volume.

Give the container about 30 seconds to fully start, then navigate to http://<raspberry_pi_ip>:9000 on any device within your network. You will be greeted by the Portainer login page.

Logging into Portainer

On the first login, Portainer will have you create the admin account and an initial user. Once credentials are created you will be logged into the main Portainer dashboard.

From here you can start managing Docker on your Raspberry Pi via the intuitive Portainer interface. But first we will review some key areas of the interface and optimize Portainer for usage on the Raspberry Pi.

Key Portainer Interface Areas

The Portainer interface consists of the following key areas:

1. App Templates

Browse and deploy preconfigured Docker apps. Templates include popular apps like Bitwarden, Pi-hole, and many more. Easily customize them as needed.

2. Stacks

Group Docker resources defined in a Compose file into a stack. Manage, edit, and upgrade entire app suites with stacks.

3. Containers

Browse running and stopped containers. Access logs, metrics, exec shell, and manage container lifecycles.

4. Images

View Docker images available locally and from registries. Manage tags, pull new images, and scan images.

5. Volumes

Manage Docker volumes to understand storage usage. Useful for persisting container data volumes.

6. Networks

View existing virtual networks available for services and containers. Restrict access between containers on custom networks.

7. Endpoints

Integrate remote Docker environments into Portainer for unified management capabilities with multiple hosts.

With an overview of the interface in hand, let’s optimize Portainer for usage on the Raspberry Pi.

Optimizing Portainer for the Raspberry Pi

The key aspects we will tune for optimizing Portainer on the Raspberry Pi include:

  • Disabling endpoint telemetry
  • Configuring the agent to reduce overhead
  • Reviewing container deployment best practices

Disabling Telemetry Reporting

By default Portainer sends telemetry data to external servers owned by Portainer. This helps Portainer monitor usage metrics and statistics.

However on the Raspberry Pi we want to eliminate any unnecessary network overhead. Luckily, disabling telemetry reporting is straightforward:

  1. Navigate to Settings
  2. Scroll to the bottom and disable Share endpoint statistics
  3. Click Update settings to save the changes

This will prevent any endpoint statistics or telemetry reports from being sent externally from your Raspberry Pi device.

Configuring the Portainer Agent

Portainer uses an agent that runs on the Docker host to collect metrics and respond to Portainer requests from the UI.

The agent is deployed by default when Portainer starts. However, we will customize the agent configuration as one method to reduce resource consumption on the Raspberry Pi.

Access the Agents page from the Settings section. Edit the Agent deployment configuration.

Here we will make the following adjustments:

  • Set CPU limit to 500m
  • Set Memory limit to 128MB
  • Disable Collect container stats
  • Disable Collect disk usage stats

Save the changes. The Portainer instance will automatically redeploy the agent with this updated configuration tuned for reduced overhead on the Pi hardware.

Statistics around container CPU and memory usage will be less detailed as a result but this is an acceptable trade-off on Raspberry Pi builds.

Following Deployment Best Practices

When deploying containers via Portainer be mindful of the limited hardware capacity on a Raspberry Pi.

In particular, pay attention to:

Container CPU and memory allocation

Scale back limits well below max capacity to leave Pi resources available for other tasks.

Persist data outside containers

Minimize write cycles and overhead on the SD card by persisting all data to external volumes.

Use Pi-optimized container images

Choose Docker images built specifically for ARM devices when possible.

Following these deployment best practices will keep your Portainer environment running optimally on the Raspberry Pi for container management.

  5. What’s the best way to persist my Portainer Docker volume?
    For robustness, you should mount the Portainer data volume to an external drive instead of relying on the SD card. This also improves write performance.

  6. Can Portainer be used to manage remote Docker hosts?
    Yes! One of Portainer’s strengths is the ability to add remote Docker endpoints and seamlessly manage containers across multiple hosts – whether that’s a cluster of Raspberry Pis or enterprise Linux servers.

  7. Is there a desktop app for managing Portainer?
    At the moment there is no downloadable Portainer desktop application. The web UI is accessible from any desktop web browser though and supports the same features.

  8. How do I back up my Portainer instance and volumes?
    Regular backups of the Portainer data volume and Docker images are recommended. You can run a separate backup container to coordinate this process automatically.

  9. Can I restrict access to Portainer’s management capabilities?
    Absolutely – you can implement users with restricted roles that only have view or read-only access. This allows you delegate container access levels.

  10. Is Portainer free for commercial use?
