LXC Builder

The tool models Linux Container (LXC) configurations by collecting parameters such as distro, arch, memory_mb, cpus, storage_gb, and network_type, then generating deterministic config blocks suitable for host deployment. It conceptualizes each container as a defined unit with resource envelopes and networking primitives to support predictable provisioning.
The tool enforces a structured input model and provides both required (distro, arch, memory_mb, cpus, storage_gb, network_type) and optional/advanced features (profiles, binds, storage_backend). It validates inputs, checks compatibility with common LXC versions, and outputs deterministic configuration blocks suitable for host execution or automation templates.
Inputs include distro (string, e.g., ubuntu-22.04), arch (e.g., amd64, arm64), memory_mb (integer), cpus (integer), storage_gb (integer), and network_type (bridge, macvlan); optional advanced fields include profile and mounts. Outputs are LXC config fragments or templates in text form, intended for direct use on hosts or in CI pipelines. The core logic normalizes units (MB/GB), enforces resource ceilings, and resolves defaults for missing optional fields. It ensures consistency across multiple containers in a set and maintains a stable ordering of directives for reproducibility. Invalid distro or arch yields structured errors with allowed values; missing required inputs trigger field-level errors; unrealistic resource requests (e.g., memory above host capacity) return warnings and fail the generation. External data sources (distro lists) are treated as optional; unavailability uses safe defaults. Aligns with standard Linux container practices; uses SI units; assumes enterprise IT environments with common LXC tooling; no locale-specific formatting is required. Assumes a host with LXC installed and network access to configure bridges; excludes live migrations, runtime orchestration, and detailed security policy definitions; not a full container management platform.
