Hi Hamano-san Thank you for your prompt response and valuable advice.

Are you using the test-chart-0.1.0.tgz located at the URL at the end of the document as your Helm chart? I am not using the test-chart-0.1.0.tgz located at the URL at the end of the document. Instead, I am using my original Helm chart.

try modifying sample_cnf_df_simple.yaml as follows. Thank you very much for your advice. I will give it a try.

I am currently working on deploying a Cloud-Native Network Function (CNF) using Tacker. For this deployment, I am utilizing Helm charts as the method of deployment. Following the guidelines provided in the official Tacker documentation (https://docs.openstack.org/tacker/latest/user/v2/cnf/deployment_using_helm/i...), I encountered an error during the instantiation process. Despite following the steps closely, the deployment did not proceed as expected. I have attached the error logs to this email for your reference. Could you please provide assistance in troubleshooting this issue? Any insights or suggestions would be greatly appreciated. Thank you for your support. Best regards, Yohei Kumamoto
