Hi team!
I have an unused cluster I try to delete but I get an error:
Can anyone assist ? Thank you
Hey @CBaptiste !
Indeed, we cannot delete your cluster because it’s linked to a resource not managed by Terraform.
The VPC listed seems to be used by an elasticache.
Can you delete / remove linkage between your cluster and this elasticache in the AWS console?
You can have a look into those threads with users facing the same issue:
Let me know if it helps.
Cheers
Thank you @bchastanier, little issue:
I followed the guide Romain shared: this one
I listed all ressources on the resource page linked to cluster: f5f39aa3-27b6-400f-a646-72ef2f5bea4a
And I try to delete the VPC from the list:
But I get this error:
This ressources are not listed by the ressource manager. Should I delete them ? Those are Network interfaces, not sure what is this impact of deleting those
Also I have 2 clusters - I hope I won’t be impacting my production one 
Update: I cannot detach the network interfaces
Just to be sure, can you list resources linked to those ENI (doing the Resource Group) with those ENI Ids just to be sure it’s linked / used by resources to be deleted?
What is the name of the attribute in the Resource Group Manager I need to use to list those ENI ID ?
Oups sorry: Elastic network interfaces
This was solved by deleting manually all dependency - thank you for the support @bchastanier
sorry for being late on closing this
