This is a small project that demonstrates an issue with Argo CD updating Helm chart dependencies if there is any Helm OCI repository configured in the system.
|
Note
|
Helm OCI repository doesn’t even have to be used. It just needs to be added to Argo CD repository list. |
| Folder | Description |
|---|---|
|
Contains main Helm chart for the application to be installed. For simplicity, it just renders single ConfigMap.
This Helm chart depends on another chart in the |
|
Library chart that is used by main application Helm chart. |
1) Add any Helm OCI repository. It’s not going to be used by our application, it just needs to be added to Argo CD:
argocd repo add myregistry.azurecr.io/helm --type helm --name test-helm-oci-repo --enable-oci --username <username> --password <password>
2) Create new Application pointing to Helm chart in application-chart folder of this GitHub repo.
This Helm chart has dependency on another chart in library-chart folder.
argocd app create sample-app --dest-namespace argocd --dest-server https://kubernetes.default.svc --repo https://github.com/lsolovey/argocd-helm-oci.git --path application-chart --sync-policy auto
Resulting error:
time="2021-03-24T15:19:21-04:00" level=fatal msg="rpc error: code = InvalidArgument desc = application spec is invalid: InvalidSpecError: Unable to generate manifests in application-chart: rpc error: code = Unknown desc = `helm repo add --username ****** --password ****** test-helm-oci-repo myregistry.azurecr.io/helm` failed exit status 1: Error: could not find protocol handler for:"
|
Note
|
Argo CD is trying to perform helm repo add … for the Helm OCI repo.
|
3) Remove Helm OCI repository from step 1:
argocd repo rm myregistry.azurecr.io/helm
4) Try creating the same Application again:
argocd app create sample-app --dest-namespace argocd --dest-server https://kubernetes.default.svc --repo https://github.com/lsolovey/argocd-helm-oci.git --path application-chart --sync-policy auto
Application is created successfully:
application 'sample-app' created
