Kubernetes How-Tos
DigitalOcean Kubernetes (DOKS) is a managed Kubernetes service that lets you deploy Kubernetes clusters without the complexities of handling the control plane and containerized infrastructure. Clusters are compatible with standard Kubernetes toolchains and integrate natively with DigitalOcean Load Balancers and volumes.
Getting Started
Create a DigitalOcean Kubernetes cluster in the control panel to start running containerized applications in the cloud.
Monitor metrics like CPU usage, load averages, and bandwidth to support capacity planning and provide insight into cluster health. View visualizations on resource utilization for individual nodes, node pools, or clusters.
Enable autoscaling to automatically adjust the number of nodes in a cluster based on the cluster’s capacity to schedule pods. Combine with a Horizontal Pod Autoscaler (HPA) to make clusters highly responsive to resource demands.
Destroy a DigitalOcean Kubernetes cluster to permanently and irreversibly remove it from an account.
Data Storage
Create a PersistentVolumeClaim (PVC) to use DigitalOcean Volumes Block Storage for persistent data in Kubernetes clusters.
Delete a volume from a Kubernetes cluster using kubectl to permanently and irreversibly remove it from the cluster and DigitalOcean account.
Create volume snapshots to save the contents of the volume’s disk, then use the snapshot to restore or create new volumes with the same contents.
Load Balancing
Declare a DigitalOcean Load Balancer in the cluster manifest to distribute traffic across all worker nodes in the cluster.
Delete a load balancer from a Kubernetes cluster using kubectl to permanently and irreversibly remove it from the cluster and DigitalOcean account.
