What You Will Learn
Beginner
- The key differences between K8s and Docker Compose
- When to use each
- When to upgrade from Compose to K8s
| Aspect | Docker Compose | Kubernetes |
|---|---|---|
| Hosts | Single machine | Multiple machines (cluster) |
| Self-healing | No | Yes - auto-restart |
| Auto-scaling | No | Yes - HPA, VPA |
| Rolling updates | Manual | Automatic |
| Load balancing | Basic | Built-in |
| Learning curve | Low | High |
| Best for | Dev, small apps | Production, scale |
The upgrade path
Start with Docker Compose for development. When you need: multi-host, auto-scaling, self-healing, or production-grade reliability - upgrade to Kubernetes.When to Stay with Docker Compose
- Development environment
- Small projects (1-5 containers)
- Single-server deployment
- Quick prototyping
- Team is small and not ready for K8s complexity
When to Move to Kubernetes
- Production deployment with high availability
- Multiple services that need to scale independently
- Need zero-downtime deployments
- Running on multiple servers/cloud providers
- Team has DevOps expertise
Practical Exercise
Review your current Docker Compose setup
Identify: do you need multi-host? auto-scaling? self-healing?
If yes to any - it is time for Kubernetes
If no - Docker Compose is sufficient
Key Takeaways
- Docker Compose: single host, dev, simple. Kubernetes: multi-host, production, scale.
- K8s adds: self-healing, auto-scaling, rolling updates, load balancing.
- Start with Compose. Upgrade to K8s when you need production reliability.
- K8s has a steeper learning curve - invest time to learn it.
- Most companies use both: Compose for dev, K8s for production.
