This way, anything written to that directory will be persisted on the host machine. The simplest way of doing this is by mounting the host's local directory as one of the directories within the container's file system. The primary use case for mounting host file systems in containers is persisting data. First, it is essential to know that all files created or modified inside the container are not visible to the outside world. Mounting host file systems in containers is a common anti-pattern that leads to many failures. The readiness probe is employed to determine whether the application is ready to receive traffic. The liveness probe lets us test whether the application is alive.

The startup probe ensures the pod is initiated and created successfully. To do this, there are startup, liveness, and readiness probes that will help you know the status of your app and the services running inside them. To confirm whether everything is working fine, it is important to know the status of the pods and the overall health of the Kubernetes cluster. While deploying services to Kubernetes, health checks are very important to help you keep services running as expected. The more complicated your deployment, the more likely you will make one of these mistakes. With declarative configuration, Kubernetes handles the underlying complexity of containers and cluster operations, making it simple to build clusters with high availability, scalability, and security. Kubernetes uses a declarative configuration model that makes it easy to design resilient systems to both anticipated and unanticipated changes. Moreover, a node needs to be connected with other nodes to transmit data between them. Nodes can be physical or virtual machines, but they all need access to the Docker engine and kubelet service to work with the Kubernetes cluster. It also manages the workloads, schedules containers on nodes, and assigns appropriate resources to containers. The master is in charge of the cluster state and nodes’ activities. The architecture of Kubernetes consists of a master, and multiple nodes or worker nodes. It manages the containers in a cluster with a set of APIs and command line tooling to automate containerized applications' deployment, scaling, and management. Kubernetes is a container orchestration platform.
