You can create several types of Helm OCI Repositories using the JFrog Platform WebUI:
To set up a Helm OCI repository via REST API, use the Create Repository REST API and add the parameter "packageType" : "helmoci" to the Repository Configuration JSON file.
Starting from Artifactory version 7.75.3, when creating a new Helm repository, a Helm OCI repository will be created by default that is compliant with OCI, and supports OCI REST APIs instead of Helm.
You can change this setting in two ways:
To use the legacy Helm implementation for one repository, click the Use Legacy Helm button on the repository creation menu.
To change the default behavior to Helm instead of Helm OCI, navigate to Administration > Artifactory > Packages > UI settings, and deselect the Helm repository UI : Show OCI Flow first checkbox.
