Portainer
A web UI for managing Docker and Kubernetes environments, containers, stacks, and images. Standout trait is broad multi-environment/agent support, offset by the security tradeoff of needing privileged Docker socket or K8s API access.

⚙ Full Stack
Go backend embedding a BoltDB key-value store for its own config, Vue.js frontend, and an agent binary deployed per managed cluster/host that talks back to the central Portainer server.
📈 Scaling Analysis
The central Portainer server is effectively a single stateful instance (BoltDB, no clustering for HA in the open-source edition), so it scales in terms of how many remote environments/agents it can manage, not by running multiple replicas of itself.
🚀 Running on Nexlayer
Single portainer pod with a PVC for the BoltDB data file; because it needs Docker-socket or K8s-API-level access to manage workloads, it requires elevated RBAC/ServiceAccount permissions that should be scoped as tightly as Nexlayer's namespace policy allows.
