Dockerhub supports OCI artifacts, and in some cases, stores Helm charts wrapped as OCI. You can create a remote docker repository with the upstream URL of “https://registry-1.docker.io/ ” and use that repository with your helm v 3.8.0 + commands to pull images from the OCI registry.
To install a Helm chart from DockerHub:
In this example, you will pull a Helm Chart called bitnamicharts/redis from DockerHub.
1. Create a docker remote repository in Artifactory, say oci-test-docker-remote, with the URL “https://registry-1.docker.io/ ”.

2.Log in to your Helm OCI client using helm registry login command:
Make sure to replace the placeholder in bold with your own JFrog host domain.
helm registry login <YOUR_JFROG_DOMAIN>
For example:
$ helm registry login acme.jfrog.io
Username: admin
Password:
Login Succeeded
3. Now pull a Helm chart image using the Artifactory remote repository or the respective virtual repository URL (here ‘oci-test-docker’ is my virtual docker repository)
Make sure to replace the placeholders in bold with your own JFrog domain, repository name, and chart name. Specifying the version is optional.
helm pull oci://<YOUR_JFROG_DOMAIN>/<REPOSITORY_NAME>/<CHART_NAME> --version=<VERSION>
For example:
$ helm pull oci://acme.jfrog.io/helm-oci-remote/bitnamicharts/redis Pulled: acme.jfrog.io/helm-oci-remote/bitnamicharts/redis:18.3.3 Digest: sha256:b3b87725110b01f901c50cd638d082f51e8a1b7bd519fd9d34721c78659c7192
4. You can find that the OCI image is cached in the Artifactory remote repository cache.
5. You can install it using Helm directly from Artifactory using the following command:
Make sure to replace the placeholders in bold with your deployment name, domain name, and OCI image path. Specifying the version is optional.
helm install <DEPLOYMENT_NAME> oci://<ARTIFACTORY_HOST>/<REPOSITORY_KEY>/<CHART_NAME> --version=<VERSION>For example:
$ helm install redis-local oci://acme.jfrog.io/helm-oci-remote/bitnamicharts/redis Pulled: acme.jfrog.io/helm-oci-remote/bitnamicharts/redis:18.3.3 Digest: sha256:b3b87725110b01f901c50cd638d082f51e8a1b7bd519fd9d34721c78659c7192 NAME: redis-local LAST DEPLOYED: Fri Aug 4 16:53:17 2023 NAMESPACE: default STATUS: deployed REVISION: 1 TEST SUITE: None NOTES: CHART NAME: redis CHART VERSION: 18.3.3 APP VERSION: 7.0.12 ** Please be patient while the chart is being deployed **
