\n \n<\/th>\n Pod<\/th>\n Container<\/th>\n<\/tr>\n<\/thead>\n \n Definition<\/td>\n The smallest deployable unit in Kubernetes that can contain one or more containers.<\/td>\n A lightweight, standalone executable package that includes app code and dependencies.<\/td>\n<\/tr>\n \n Who manages it?<\/td>\n Managed by Kubernetes (AKS) as a Kubernetes object.<\/td>\n Managed by a container runtime (e.g., Docker, containerd).<\/td>\n<\/tr>\n \n Composition<\/td>\n Can include multiple containers, shared storage volumes, and shared network namespace.<\/td>\n Single process\/environment with its own filesystem and libraries.<\/td>\n<\/tr>\n \n IP Address & Network<\/td>\n Each pod gets its own IP; containers in the same pod share that IP and network namespace.<\/td>\n Containers inside the same pod do not have separate IPs; they use the pod’s IP.<\/td>\n<\/tr>\n \n Lifecycle<\/td>\n Created, scheduled, scaled, and deleted by Kubernetes (often via Deployments).<\/td>\n Started and stopped by the container runtime as part of a pod.<\/td>\n<\/tr>\n \n Scaling<\/td>\n Scaling is done at pod level (more pod replicas).<\/td>\n Containers inside a pod scale together as the pod is replicated.<\/td>\n<\/tr>\n \n Use Case<\/td>\n Represents a logical application unit (e.g., app container + sidecar\/logging container).<\/td>\n Represents a single app component or service (e.g., web server, worker).<\/td>\n<\/tr>\n \n Configuration<\/td>\n Defined in Kubernetes manifests (YAML) as a Pod spec.<\/td>\n Defined as a container image (Dockerfile) and referenced inside pod specs.<\/td>\n<\/tr>\n \n Sharing Resources<\/td>\n Containers in a pod share storage volumes and localhost network.<\/td>\n Each container has its own process space and filesystem (from its image).<\/td>\n<\/tr>\n \n Direct Deployment in Kubernetes<\/td>\n Yes, pods are deployed directly or via higher-level objects (Deployment, ReplicaSet).<\/td>\n No, containers are not deployed directly; they always run inside pods.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n <\/h3>\n
