Question

How can I use ldapvi in my Nubus/OpenDesk Environment?

Advance notice

Please keep in mind, that the prefix (ums-) possibly needs to be adjusted depending on the environment

Answer

ldapvi is not installed by default on the LDAP server pods. A simple approach is to use a temporary debug container.

$ kubectl apply -n ${NAMESPACE?} -f - <<EOF
apiVersion: v1
kind: Pod
metadata:
  name: ldap-debug
spec:
  restartPolicy: Never
  containers:
  - name: debug
    image: alpine
    command: ["sh","-c","sleep infinity"]
    envFrom:
    - configMapRef:
        name: ums-ldap-server-primary
    - secretRef:
        name: ums-ldap-server-admin
EOF

Next, the corresponding debug pod needs to be prepared, ldapvi and an editor of your choice installed:

$ kubectl exec -n ${NAMESPACE?} ldap-debug -i -t -- sh
 apk add ldapvi vim
 […]
 export EDITOR=vim
 export VISUAL=vim

Afterwards, the debug pod is ready to use and you can access ldapvi as follows within the debug-pod:

$ ldapvi --host ums-ldap-server-primary -D "$ADMIN_DN" -w "$password" -b "$LDAP_BASEDN"

Cleanup

After finishing the manual adjustments, you can simply remove the debug pod with the following command:

$ kubectl delete pod -n ${NAMESPACE?} ldap-debug
