What should I use for self healing containerized apps?

For self-healing containerized apps, the best choice depends on how much orchestration you need:
Best general choice: Kubernetes
Use Kubernetes if you want your containers to automatically:
- restart when they fail
- reschedule on another node if a machine dies
- scale up/down
- recover from unhealthy states
Key features for self-healing:
- liveness probes: restart unhealthy containers
- readiness probes: remove unready containers from traffic
- replica controllers / Deployments: keep the desired number of pods running
- automatic rescheduling: move workloads if a node fails
Simpler alternatives
- Docker Compose: okay for local dev or very small setups, but limited self-healing
- Docker Swarm: simpler than Kubernetes, has restart policies and basic rescheduling, but less powerful and less commonly used
- Nomad: good lighter-weight orchestration option, with self-healing capabilities
- Amazon ECS / Azure Container Apps / Google Cloud Run: managed options with built-in recovery and scaling, less operational burden
Recommendation
- Production, portability, and robust self-healing: Kubernetes
- Small/simple deployment: managed container platform like Cloud Run or ECS/Fargate
- Local/dev only: Docker Compose
If you want, I can also compare Kubernetes vs ECS vs Nomad specifically for self-healing behavior.
