Portainer: Container and Kubernetes management interface
Web-based management platform for multi-orchestrator container environments.
Learn more about portainer
Portainer is a container management platform delivered as a single containerized service that runs on Linux or Windows. It communicates with container orchestration APIs to provide unified resource management across multiple deployment targets. The application exposes both a web interface and REST API for managing containerized workloads and their associated infrastructure. It supports multiple orchestration backends including Docker Engine, Docker Swarm, Kubernetes clusters, and Azure Container Instances.
Single container deployment
Portainer runs as a single container instance that can be deployed to any cluster without additional dependencies or complex setup procedures.
Multi-orchestrator support
Manages resources across Docker, Swarm, Kubernetes, and ACI environments through a unified interface rather than requiring separate tools for each platform.
Dual interface model
Offers both a web GUI and comprehensive REST API for resource management, allowing both interactive administration and programmatic integration.
