These are typically managed by controllers like Deployments.</p> <p>However, other workloads only need to run once and finish, such as scripts, data processing tasks, or backups. Kubernetes provides Jobs and CronJobs to handle these types of workloads.</p> <h1 id="table-of-contents">Table of Contents</h1> <nav id="TableOfContents"> <ol> <li><a href="#job">Job</a></li> <li><a href="#cron">Cron</a></li> <li><a href="#init-container">Init Container</a></li> </ol> </nav> <h3 id="job">Job</h3> <p>A Job is a Kubernetes resource used to run a task until completion.</p> https://marktaguiad.dev/post/k8s-notes-part8/ Sun, 08 Mar 2026 00:00:00 +0000marktaguiad@marktaguiad.dev (Mark Taguiad) https://marktaguiad.dev/post/k8s-notes-part8/ <p><img class="theme-image" src="https://marktaguiad.dev/images/devops/k8s-notes/k8s-notes-daemonset-001.png" data-light="/images/devops/k8s-notes/k8s-notes-daemonset-001.png" data-dark="/images/devops/k8s-notes/k8s-notes-daemonset-dark-001.png" alt="Architecture Diagram" > Kubernetes has multiple controllers to manage workloads. So far, we’ve learned about Deployments and StatefulSets, which help run Pods that scale and keep state. However, some workloads must run on every node in a cluster — this is where DaemonSets come in.</p> <h1 id="table-of-contents">Table of Contents</h1> <nav id="TableOfContents"> <ol> <li><a href="#why-daemonsets">Why Daemonsets?</a></li> <li><a href="#example-of-daemonsets-systems">Example of Daemonsets Systems</a></li> <li><a href="#create-daemonsets">Create Daemonsets</a></li> <li><a href="#service">Service</a></li> <li><a href="#volume">Volume</a></li> <li><a href="#excluding-certain-nodes">Excluding Certain Nodes</a> <ol> <li><a href="#node-taints">Node Taints</a></li> <li><a href="#node-affinity--labels">Node Affinity &amp; Labels</a></li> <li><a href="#anti-affinity">Anti-affinity</a></li> <li><a href="#node-selector">Node Selector</a></li> </ol> </li> </ol> </nav> <h3 id="why-daemonsets">Why Daemonsets?</h3> <p>Most Kubernetes workloads (like Deployments) allow Pods to run anywhere in the cluster.
