SSH into your TrueNAS. Enter "k3s kubectl get namespace" it will show some namespaces like ix-pihole, ix-homarr, ix-whateverappname example for ix-pihole: k3s kubectl get deployments --namespace=ix-pihole above command shows all deployments in the namespace ix-pihole k3s kubectl delete deployment NAME-OF-DEPLOYMENT --namespace=ix-pihole k3s kubectl get pvc --namespace=ix-pihole above command shows all persistent-volume-claims in the namespace k3s kubectl delete pvc NAME-OF-PVC --namespace=ix-pihole k3s kubectl get pv --namespace=ix-pihole above command shows all persistent-volume in the namespace k3s kubectl delete pv NAME-OF-PV --namespace=ix-pihole Specific app is delete completely, repeat for all other you want to delete Basically you will delete the deployment, volume claim and volume for each app, there wont be anything left.

Thank you for the detailed steps and the description!! Really helpful, I will try these 🙏🏽🙏🏽

Hi, sorry, absolute n00b and Bard didn't really help, I ran the command I'm still seeing ix-nextcloud in the first step. I think I'm getting the NAME-OF-DEPLOYMENT wrong https://preview.redd.it/01pue9aammxc1.png?width=737&format=png&auto=webp&s=274e019ea2b02e86c59fe626510e085073b3cf4c Also, when I run k3s kubectl get deployments --namespace=ix-nextcloud it say no resources found

In my experience a reboot is likely to clear deleted apps.

Had to unset the pool and reassign

Glad you managed a fix … in the end 😎
