Pros & Cons
10 pros·6 cons across both
Docker
Pros
- Massive ecosystem with 13.1M+ public images on Docker Hub
- Standardized Dockerfile syntax and OCI image format for portability
- Native Kubernetes integration and Docker Compose orchestration
- Extensive tooling: Docker Buildx, Docker Scan, Docker Desktop for local development
- Industry standard with 82% enterprise container adoption
Cons
- Higher memory overhead (20-50MB per container) limits density on single host
- Slower startup times (500-2000ms) impact rapid scaling scenarios
- Requires Docker daemon running, single point of failure in older versions
LXC (Linux Containers)
Pros
- Minimal memory overhead (5-15MB per container) enables 10x+ container density
- Fast startup times (100-500ms) for rapid scaling
- Full OS-level control with direct cgroup and namespace manipulation
- Lightweight footprint suitable for edge computing and resource-constrained environments
- Native support for system containers (running full Linux distributions)
Cons
- Minimal ecosystem—no standard image format or public repository equivalent to Docker Hub
- Steep learning curve requiring deep Linux kernel knowledge for non-trivial deployments
- No standardized orchestration tooling; requires custom solutions or third-party integration
Frequently Asked Questions
5 questions
Not directly. LXC excels at system containers (full OS environments), while Docker optimizes for application containers (single services). LXC can run full Linux distributions; Docker typically packages one application per image. For microservices and CI/CD pipelines, Docker is the standard. For VM replacement or infrastructure automation, LXC is superior.
