Main differences between Deployment and DaemonSet in Kubernetes:
-
Deployment manages the creation and updating of a set of Pods with the same configuration. It ensures scalability and application updates by creating the required number of replicas, which can run on any available nodes in the cluster.
-
DaemonSet guarantees that a copy of a Pod is running on each (or selected) node in the cluster. This is useful for tasks that must run on all nodes, such as system monitoring, logging, or network agents.
Example:
- Deployment: a web application with 3 replicas distributed across nodes.
- DaemonSet: a monitoring agent running on every node.
Thus, Deployment focuses on scalability and updates, while DaemonSet is for running Pods on all nodes for system tasks.
