Classification: Ingress Hardening & Attack Surface Reduction
Status: Implemented & Verified
Executive Summary
This report documents the architectural lifecycle of container management on Bastion: from initially deploying a web-based GUI (Portainer) to overcome early CLI friction, to identifying the inherent security risks of host-socket mounting, and finally decommissioning the interface in favor of key-authenticated, terminal-native tooling (lazydocker).
Phase 1: Initial Deployment & Context
Why Portainer Was Introduced
When initially transitioning to Docker and container orchestration, early CLI management presented significant friction. Debugging multi-container networks, diagnosing container start failures, and managing persistent volume paths purely through raw shell commands often led to silent errors and operational overhead.
