☸️ Kubernetes Flashcards
☸️ What is Kubernetes?
Kubernetes is an open-source container orchestration platform for automating deployment, scaling, and operations of applications.
📦 What is a Pod?
A Pod is the smallest deployable unit in Kubernetes that can host one or more containers.
📡 What is a Service?
A Service exposes a set of Pods as a network service, enabling communication between components.
🔁 What is a ReplicaSet?
A ReplicaSet ensures a specified number of Pod replicas are running at any time.
⚙️ What is a Deployment?
A Deployment provides declarative updates for Pods and ReplicaSets, supporting rollout and rollback of app versions.
🌐 What is Ingress?
Ingress manages external access to services in a cluster, typically HTTP/HTTPS traffic, using routing rules.
🔐 What is a Secret?
A Secret is an object used to store sensitive data such as passwords, tokens, and keys.
💾 What is a ConfigMap?
A ConfigMap is used to store non-confidential configuration data in key-value pairs, injected into Pods.
🔄 What is a DaemonSet?
A DaemonSet ensures a copy of a Pod runs on all (or some) nodes in the cluster, often used for log collection or monitoring agents.
📅 What is a CronJob?
A CronJob runs scheduled jobs at specific times, like backups or periodic cleanup tasks.
💻 What is kubelet?
Kubelet is the primary node agent that runs on each node and ensures containers are running in Pods.
🛠️ What is Helm?
Helm is a package manager for Kubernetes, helping define, install, and upgrade complex applications using charts.
