Automated Microservice Deployment Pipeline with Version Tracking

Create a Bash script that automates the deployment of microservices across Kubernetes clusters, including semantic versioning, Git tag generation, and rollback capabilities. The script must dynamically parse service configurations from a YAML manifest, validate container images, perform zero-downtime deployments, and log all deployment events with precise timestamps and deployment metadata. Include robust error handling that can detect and automatically roll back failed deployments.
