Managing Workloads

The workload is an application running on Kubernetes Engine. You can create a namespace and then add or remove workloads. Workloads are created and managed item by item, such as deployments, pods, stateful sets, daemon sets, jobs, and cron jobs.

Managing Deployment

Deployment is a resource that provides updates for pods and replica sets. You can create a deployment in a workload, check its details, or delete it.

Creating Deployment

To create a deployment, follow these steps.

1. Click on the menu for all services > Container > Kubernetes Engine. It moves to the Service Home page of Kubernetes Engine.
2. On the Service Home page, click Deployment under the Workload menu. It moves to the List Deployment page.
