Installation from a Remote Registry

Now that our chart is stored in the Harbor OCI registry, we can install it directly from there. This is useful for sharing charts across teams or deploying them in different environments without needing to package them locally each time.

To install the chart from the OCI registry, we can use the following command:

# Remove any previous installation
# to start fresh
helm uninstall my-todo-chart -n todo-chart --ignore-not-found
kubectl -n todo-chart delete pvc --all --ignore-not-found
kubectl delete namespace todo-chart --ignore-not-found

# Install the chart from the OCI registry
helm install todo-chart oci://$MASTER_PUBLIC_IP:30003/todo-app/todo-chart \
    --version 0.1.0 \
    -n todo-chart \
    --create-namespace \
    -f $HOME/todo-chart-custom/values.yaml

We can verify that the installation was successful by checking the pods:

kubectl get pods -n todo-chart

We can run the tests to ensure everything is working correctly:

helm test todo-chart -n todo-chart
