Portainer
Overview
Portainer provides a web-based management interface for Docker on SilverLinux.
It is used to manage containers, networks, volumes, images and Docker stacks through a graphical interface instead of using the command line.
Service Information
URL
https://portainer.silveressence.net
Container Name

Docker Network

Purpose
Portainer is used for:
- Managing Docker containers
- Managing Docker networks
- Managing Docker volumes
- Viewing logs
- Deploying Docker stacks
- Monitoring running services
- Performing container maintenance
Data Storage
Docker Socket
/var/run/docker.sock
This allows Portainer to communicate with the Docker engine.
Portainer Data
Docker Volume:
portainer_portainer_data
Purpose:
- User accounts
- Configuration
- Stack definitions
- Environment settings
Security
Portainer has administrative access to Docker.
Because Portainer uses the Docker socket, users with Portainer administrator access effectively have administrative access to the server.
Only trusted administrators should have access.
Backup Requirements
The following volume should be included in backups:
portainer_portainer_data
Loss of this volume will result in:
- Loss of Portainer users
- Loss of stack definitions
- Loss of Portainer configuration
Docker containers and application data remain unaffected.
Network Configuration
Portainer is connected to the Docker proxy network.
Applications exposed through Nginx Proxy Manager can communicate with Portainer through this network.
Maintenance
View logs:
docker logs portainer
Restart:
docker restart portainer
Open shell:
docker exec -it portainer /bin/sh
