Buildah.
#3 Kubernetes - A Container Orchestration Platform for Advanced Container Workflows
For more complex container operations, Kubernetes, sometimes known as K8s,
is a well-liked open-source container orchestration technology that may
substitute Docker Desktop. While Kubernetes offers a complete solution for
managing and orchestrating containers at scale, Docker Desktop focuses on
offering a user-friendly interface for container development.
Features of Kubernetes:
Container networking: Creating
complicated network topologies for containerized applications is simple
because to Kubernetes' advanced networking paradigm, which enables
communication between containers within a cluster...
Storage management: Kubernetes
has container storage management capabilities such as support for multiple
storage backends, volume provisioning, and data persistence..
Service discovery and DNS: By
enabling containers to find and interact with one another using DNS names,
Kubernetes' built-in service discovery and DNS functionalities make it
