README

kilo-wg-gen-web

kilo-wg-gen-web enables using Wg Gen Web as a UI to define and manage peers for Kilo.

Build Status Go Report Card

Getting Started

To run kilo-wg-gen-web, first install Kilo. Next, edit the included manifest and set the NODE variable to the name of one of the nodes in the Kilo mesh, i.e. the node that clients should use to connect to the mesh. Finally, deploy the included manifest, which contains the configuration for both Wg Gen Web as well as kilo-wg-gen-web:

kubectl apply -f https://raw.githubusercontent.com/squat/kilo-wg-gen-web/master/manifests/kilo-wg-gen-web.yaml

OIDC + RBAC

Anyone with access to the Wg Gen Web UI will have access to create, read, update, and delete Kilo Peers, which means they can grant access to the VPN to other users. OIDC and RBAC can be used in order to restrict access to only users who are authenticated and authorized to perform certain actions on Peer resources. To get started, first ensure that the Kubernetes API server is configured to validate OIDC tokens. Afterwards, edit the included OIDC + RBAC manifest, which configures an OAuth2 proxy and an RBAC proxy in front of the Wg Gen Web UI to set the NODE variable as well as add the necessary OIDC configuration and credentials to the kilo-wg-gen-web Secret. Next, deploy Wg Gen Web with OIDC and RBAC:

kubectl apply -f https://raw.githubusercontent.com/squat/kilo-wg-gen-web/master/manifests/kilo-wg-gen-web-oidc-rbac.yaml

Finally, grant access to certain privileges in Wg Gen Web by creating Kubernetes ClusterRoles and ClusterRoleBindings. For example, the following command could be used to grant access to view the Wg Gen Web UI to the user example@example.com:

cat <<EOF | kubectl apply -f -
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: view-peers
rules:
- apiGroups:
  - kilo.squat.ai
  resources:
  - peers
  verbs:
  - get
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: example-view
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: view-peers
subjects:
- apiGroup: rbac.authorization.k8s.io
  kind: User
  name: example@example.com
EOF

Access to create Peers via the UI could be granted to the user example@example.com with the following command:

cat <<EOF | kubectl apply -f -
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: edit-peers
rules:
- apiGroups:
  - kilo.squat.ai
  resources:
  - peers
  verbs:
  - update
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: example-view
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: edit-peers
subjects:
- apiGroup: rbac.authorization.k8s.io
  kind: User
  name: example@example.com
EOF
