Container Orchestration
Tools and concepts for managing containers at scale.
The terms of container orchestration, led by Docker and Kubernetes: containers, pods, services, deployments and Helm, plus the Kubernetes objects and components that keep workloads running such as nodes, namespaces, ingress, config, storage and autoscaling.
Use it when
- You need a precise definition of a Kubernetes or Docker term.
- You are reading a manifest or an incident report and need the vocabulary.
Watch out for
- Kubernetes terms mean specific API objects; do not use them interchangeably (a Deployment manages ReplicaSets, which manage Pods).
- Object names and defaults vary slightly between Kubernetes versions and distributions.
The data
19 rows
| Term | Description |
|---|---|
| Docker | Platform for building and running containerized applications. |
| Kubernetes | Open-source container orchestration platform. |
| Container | Lightweight isolated runtime environment. |
| Pod | Smallest deployable unit in Kubernetes holding one or more containers. |
| Service | Kubernetes abstraction exposing a set of pods as a network service. |
| Deployment | Kubernetes controller managing pod replicas and updates. |
| Helm | Package manager for Kubernetes applications. |
| Node | A machine, virtual or physical, that runs pods and is managed by the control plane. |
| Namespace | A logical partition of a cluster used to separate teams, environments and resource quotas. |
| ReplicaSet | Ensures a specified number of identical pods are running; usually managed by a Deployment. |
| StatefulSet | Manages pods that need stable identity and storage, such as databases. |
| DaemonSet | Runs one copy of a pod on every node, used for log collectors and agents. |
| Ingress | Routes external HTTP and HTTPS traffic to services inside the cluster. |
| ConfigMap | Holds non-secret configuration that pods consume as environment variables or files. |
| Secret | Holds sensitive values such as tokens and keys; base64-encoded by default and needs encryption at rest for real protection. |
| Kubelet | The agent on each node that ensures the containers described by pod specs are running. |
| etcd | The consistent key-value store that holds all cluster state for the control plane. |
| Horizontal Pod Autoscaler | Adjusts the number of pod replicas based on observed metrics such as CPU use. |
| Persistent Volume | A piece of cluster storage that outlives individual pods, claimed through a PersistentVolumeClaim. |
