# Application Deployment

Before creating a new workload, you need to create and register imagePullSecrets. Please refer to [this link.](https://cocktailcloud.gitbook.io/cocktail-cloud-online-en/configmap-secret#id-2.5-creating-imagepullsecrets)

## 1. Workload Group Creation

Create a workload group on the Workload tab of the Service Map.

1\) Click on \[Application] - \[Service Map] tab, select the service map where you want to create the workload, and navigate to the Workload.

2\) Click the expand menu (three dots) next to the workload group name.

3\) Choose the desired direction for adding a group from the additional items (e.g., Add Group to the Right).

To delete a workload group, there should be no workloads within that group. If there were existing workloads in the group, they must be deleted first.

To delete a workload group, click the "expand menu (three dots)" displayed to the right of the workload group name. You will see "Delete Group" is activated and displayed in the popup. Select this option.
