Container Deployment

Run your own container workloads directly on the edge with Portainer, a web-based container management interface built into every mrxnode device. This guide walks you through deploying and managing containers on your device.

Overview

Each mrxnode device includes Portainer CE, a web-based container management interface. You can deploy and manage Docker containers directly on your edge device, alongside the Mirox-Agent workloads.

Accessing Portainer

Portainer is available on your mrxnode's IP address:

Login with the appuser credentials (see mrxnode Overview for password information).

Deploying Containers

Using the Web Interface

1. Open Portainer in your browser
2. Navigate to Containers in the left sidebar
3. Click Add container
4. Configure your container:
   • Name: Give your container a descriptive name
   • Image: Enter the Docker image (e.g., nginx:latest, redis:alpine)
   • Ports: Map container ports to host ports
   • Volumes: Mount persistent storage (see below)
5. Click Deploy the container

Pulling Images

Portainer can pull images from:

• Docker Hub (public images)
• Private registries (configure credentials in Portainer settings)

Persistent Storage

Containers are ephemeral by default - their data is lost when they stop or restart. To persist data across reboots and system updates, use Docker volumes.

Creating a Volume

1. Go to Volumes in the left sidebar
2. Click Add volume
3. Enter a name for your volume
4. Click Create the volume

Mounting Volumes to Containers

When creating or editing a container:

1. Scroll to the Volumes section
2. Click map additional volume
3. Select your volume and specify the container path (e.g., /data)
4. Deploy or update the container

Best Practices

• Resource limits: Set memory and CPU limits to prevent containers from consuming all device resources
• Auto-restart: Enable restart policies for containers that should run continuously
• Logging: Configure log rotation to prevent disk space issues
• Security: Only deploy trusted container images
