Kubernetes Labels and Annotations in Zeet Deployment
Service Containers & Job Containers
Containers are a standardized and portable way to package software applications and their dependencies. This ensures consistent performance across different computing environments. With Zeet, deploy containers in your cluster, scale them with replicas for high compute power and availability, and take advantage of various cluster types.
When you deploy a container with Zeet, it comes pre-configured with a set of labels and annotations. These preset values facilitate users in identifying and managing Kubernetes objects associated the deployment.
