delete-app

彻底删除应用——不仅清除 Kubernetes 资源，还将一并移除关联的 NAS 数据库。在删除应用时，务必同时检查 K8s 与 NAS。

description: Delete an application completely — Kubernetes resources AND any associated NAS database. Always check both K8s and NAS when deleting an app.

Delete Application (Full Cleanup)

The orchestrator handles user confirmation via submit_plan before dispatching this task. Proceed directly with deletion.

When deleting an application, ALWAYS check and clean up BOTH locations:

  1. •Kubernetes — namespace, deployments, services, ingress, secrets
  2. •NAS (192.168.1.2) — associated PostgreSQL database container + data directory

NEVER

  • •Do NOT delete namespaces: default, kube-system, kube-public, ingress-nginx, cert-manager, a2a, ask.
  • •Do NOT call ask_human — it is deprecated. The user already confirmed.

Steps

Step 1: Identify and delete Kubernetes resources

bash
# List everything in the namespace
kubectl get all,ingress,secret,configmap,pvc -n <namespace>

# Delete the entire namespace (removes all resources at once)
kubectl delete namespace <namespace>

# Verify deletion
kubectl get ns <namespace>

If the app is in a shared namespace, delete only its specific resources:

bash
kubectl delete deployment,service,ingress,secret,configmap -l app=<name> -n <namespace>

Step 2: Check NAS for associated database

ALWAYS do this — even if not explicitly asked. Applications often have a PostgreSQL database on the NAS.

bash
# List all postgres containers, look for ones matching the app name
ssh nblotti@192.168.1.2 'docker ps -a --filter ancestor=postgres --format "table {{.Names}}\t{{.Status}}\t{{.Ports}}"'

Common naming patterns: <app>-postgres, <app>-db, <app>-pg

Step 3: Delete NAS database (if found)

bash
# Get the data directory from the container
ssh nblotti@192.168.1.2 'docker inspect <container-name> --format "{{range .Mounts}}{{.Source}} -> {{.Destination}}{{println}}{{end}}"'

# Remove the container
ssh nblotti@192.168.1.2 'docker rm -f <container-name>'

# Delete the data directory (use Docker for privileged file ops)
ssh nblotti@192.168.1.2 'docker run --rm -v /volume1:/volume1 alpine rm -rf /volume1/<data-dir>'

# Verify
ssh nblotti@192.168.1.2 'docker ps -a --filter name=<container-name>'
ssh nblotti@192.168.1.2 'ls /volume1/<data-dir> 2>&1 || echo "Directory deleted"'

Step 4: Report summary

Report what was deleted:

  • •K8s namespace/resources removed: yes/no
  • •NAS database container removed: yes/no (name, port)
  • •NAS data directory removed: yes/no (path)
