Ansible is better than Bash if your goals include:

* Automating repetitive tasks across many servers.

* Ensuring idempotent configurations (e.g., setting up web servers, installing packages consistently).

* Managing infrastructure as code for better version control and collaboration.

* Orchestrating complex workflows that involve multiple steps or dependencies.

However, Ansible is not a container orchestrator.

Kubernetes (K8s) provides capabilities that Ansible or Docker-Compose cannot match. While Docker-Compose only supports a basic subset, Kubernetes offers:

* Advanced orchestration features, such as rolling updates, health checks, scaling, and self-healing.

* Automatic maintenance of the desired state for running workloads.

* Restarting failed containers, rescheduling pods, and replacing unhealthy nodes.

* Horizontal pod auto-scaling based on metrics (e.g., CPU, memory, or custom metrics).

* Continuous monitoring and reconciliation of the actual state with the desired state.

* Immediate application of changes to bring resources to the desired configuration.

* Service discovery via DNS and automatic load balancing across pods.

* Native support for Persistent Volumes (PVs) and Persistent Volume Claims (PVCs) for storage management.

* Abstraction of storage providers, supporting local, cloud, and network storage.

If you need these features but are concerned about the complexity of Kubernetes, consider using a managed Kubernetes service like GKE or EKS to simplify deployment and management. Alternatively, and this is my prefered option, combining Terraform with a Container-as-a-Service (CaaS) platform allows the provider to handle most of the operational complexity for you.
