Managing Workloads

The workload is an application that runs on Kubernetes Engine. After creating a namespace, you can add or delete workloads. Workloads are created and then managed for each item such as Deployment, Pod, StatefulSet, DaemonSet, Job, and CronJob.

Managing Deployments

A Deployment is a resource that provides updates for Pods and ReplicaSets (ReplicaSet). You can create a deployment in the workload, view its details, or delete it.

Create Deployment

To create a deployment, follow the steps below.

1. Click the All Services > Container > Kubernetes Engine menu. 1. Go to the Service Home page of Kubernetes Engine.
2. On the Service Home page, click Deployment under the Workload menu. 2. Go to the Deployment List page.
3. Deployment List page, after selecting the cluster and namespace from the list in the upper left, click Create Object.
4. In the Object Creation Popup, enter the object information and click the Create button.
