Q&A

• What are Kubernetes volumes and namespaces?

  Volumes represent locations where containers can access and store information, backed by various storage backends. Namespaces function as a grouping mechanism, providing isolation for services, pods, replication controllers, and volumes. They allow cooperation within a namespace and isolation from other parts of the cluster.

• Who are Sippy and Goldy?

  Sippy and Goldy became best friends on the ship. Goldy gave Sippy a present, making Sippy sad for an unknown reason.

• What do Kubernetes services enable?

  Kubernetes services facilitate communication among pods and replication controllers. They enable service discovery and provide stable access to applications.

• How does Kubernetes manage multiple containers inside a pod?

  Kubernetes allows running multiple containers in a pod. Replication controllers manage pod replication and scaling. Kubernetes handles pod lifecycle, rolling deployments, and monitoring.

• What are the key focuses of Kubernetes?

  Kubernetes, led by Google, focuses on building a robust platform for running thousands of containers in production. It uses labels to identify and query resources, and pods represent a runnable unit of work.

• Why is a PHP app moved into a container?

  The PHP app environment, including the web server, file system, and PHP engine, is moved into a container for better management. However, managing isolated containers poses challenges such as connecting to the external world, shared file systems, networking, and scheduling. A new solution involving a ship made of connected rafts offers a way to tackle these challenges.

• What is Kubernetes?

  Kubernetes is an open source orchestration system for docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads. It uses concepts of labels and pods to group containers into logical units for easy management and discovery.
