#What is kubernetes cluster orchestration portable

The Kubernetes API lets users define the desired end state of their applications via logical constructs like deployments, replicasets, config-maps, services etc. It can also allocate storage and persistent volumes to running containers, provides a way to inject global config variables, implements auto-scaling, and maintains the desired state for applications. Kubernetes manages workload distribution for containerized applications across a cluster of hosts and will dynamically roll out the container networking, routing and ingress needed for applications running in containers. It’s a system that automates the deployment and management of containerized applications on a given cloud platform or on-premises infrastructure. Kubernetes helps orchestrate containerized applications to run on a cluster of hosts. A platform that can orchestrate, manage and define dependencies and configs for containerized applications becomes necessary for production systems.

How can containers share common config data?Ī microservices application may be spread across multiple services backed by multiple containers, increasing complexity.

How do you migrate containers from one host to another for host maintenance?.

How can you isolate two containers on the same host such that they cannot talk to each other?.

How do you determine AND scale the number of containers when application workloads increase?.How do you expose containers running on host to external/ingress traffic?.What happens if a running container has a problem or dies?.However, an application running in a container still needs management.

They also help simplify application operations by being portable across multiple hosts and cloud platforms. Containers accelerate development pipelines by removing the need to build, test and validate application code across multiple operating systems.
