Setup Addons
Add-On Components
Upon deploying a Kubernetes cluster, it becomes essential to install a series of add-on components (addons). These addons are often crucial for the regular operation of the cluster.
The addon-manager, commonly utilized to manage the add-ons in a cluster, operates within the Kubernetes cluster's Master node. It oversees all the extensions in the $ADDON_PATH (defaulting to /etc/kubernetes/addons/) directory to ensure they are functioning as intended.
Some of the common components include:
For additional extensions, refer to Installing Addons and Legacy Addons.
Power-Up Your Kubernetes: Essential Add-Ons for Peak Performance
Once you've got your Kubernetes cluster up and running, think of it like a smartphone without apps—it's functional, but you're not getting the most out of it. That's where add-ons come in—they're like the apps that power-up your cluster's capabilities.
Picture a digital maestro—addon-manager—nestled within the Master node of your Kubernetes command center. This wizard is keeping an eagle eye on the $ADDON_PATH (which, by default, is the /etc/kubernetes/addons/ directory), ensuring every component is humming along just right.
Ready for the tour? Here's the all-star lineup of add-ons that can turn your cluster into a powerhouse:
Command Central, addon-manager: Keeps your add-ons tightly regulated.
Traffic Cop, cluster-loadbalancing: Directs digital traffic efficiently.
Mission Control, dashboard: A clear visual on your cluster activities.
The Muscle, device-plugins/nvidia-gpu: Amping up your computing power.
The Balancer, dns-horizontal-autoscaler: Keeps network naming at peak performance.
The Communicator, dns: For seamless service-name resolutions.
The Analyzer, fluentd-elasticsearch: Dives deep into data logs.
Stealth Mode, ip-masq-agent: Keeps IP addresses under wraps.
The Envoy, istio: Smart networking for your services.
The Enforcer, kube-proxy: Manages network rules and connections.
The Scout, metrics-server: Keeps an eye on resource usage.
The Watchdog, node-problem-detector: On the lookout for pesky issues.
The Statistician, prometheus: Monitors and alerts like a pro.
The Organizer, storage-class: Manages your storage needs efficiently.
For those hungry for even more power-ups, gear up with additional extensions detailed in Installing Addons and for a nostalgic twist, visit Legacy Addons. Your Kubernetes cluster is set for the big leagues now!
