8. Select the image repository and enter the authentication information, then click the Connection Test button.
9. Enter the remaining information and click the Next button.

   Item	Description
   Image Repository Information	Select the image repository and enter the authentication information. Administrator privileges are required for the image repository. The user who will use the Helm Chart to perform Helm Install will be granted Read privileges for the image repository. The entered authentication information will be used to grant privileges to the image repository.
   Add Used Images	Add the image paths from the selected image repository. Select images from the list: Organization, Repository, and Tag can be selected and added. User input: The docker repository and docker tag of the image can be entered directly and added. Multiple inputs are possible.
   Use Register’s Authentication Information	This option is available when the selected image repository is a tool that cannot grant privileges (e.g., SCR). If not checked, when a user performs Helm Install, the user will be granted Pull privileges for the used image. If the tool cannot grant privileges, no privileges will be granted. If checked, the Helm Chart user will use the registrant’s authentication information instead of their own privileges when performing Helm Install. Be cautious when checking this option: The registrant’s authentication information may be exposed to the Helm Chart user, so use this option only when necessary. This option must be selected for image repositories that only provide image pull functionality. A separate image repository for pull purposes only must be entered. (If checked, one image repository cannot be used for both pull and push at the same time.) The registrant’s authentication information is used in Project > Image Repository > Pull-only Image and Helm Release’s Image Pull Secret. This information cannot be changed by the Helm Chart user, and changes to the registrant’s authentication information in the Helm Chart will be applied universally.
   Select Docker Base Image	Select the image to be used as the Docker base image. This option is only available if Support CI/CD was selected in the previous step. The selected image will be used as the base image for Docker build.
