 1 | # external-dns-ui
 2 | 
 3 | External-dns-ui is a read-only web-based UI for external-dns (https://github.com/kubernetes-sigs/external-dns).
 4 | 
 5 | The purpose of the project is to provide a quick overview of the creation status of Ingress DNS records via a correctly configured external-dns.
 6 | 
 7 | ![screenshot](screenshots/external-dns-ui_1.jpg)
 8 | 
 9 | ⚠️⚠️⚠️ This project is in alpha stage, use at your own risk ⚠️⚠️⚠️
10 | 
11 | :heart: Inspired by and based on Gatekeeper Policy Manager https://github.com/sighupio/gatekeeper-policy-manager :heart:
12 | 
13 | ## Requirements
14 | 
15 | - Kubernetes cluster
16 | - Correctly configured deployment of `external-dns`
17 | 
18 | ## How to deploy external-dns-ui
19 | 
20 | Simply apply the Kubernetes manifests generated via `manifests/kustomization.yaml` into your Kubernetes cluster. For example:
21 | 
22 | ```bash
23 | kubectl apply -k manifests
24 | ```
25 | 
26 | ⚠️ Please ensure that the namespace specified inside `manifests/kustomization.yaml` is the namespace where your external-dns is running.
27 | 
28 | Once you've deployed external-dns-ui, if you haven't set up an ingress, you can access the web-UI using port-forward:
29 | 
30 | ```bash
31 | kubectl -n external-dns port-forward svc/external-dns-ui 8000:80
32 | ```
33 | 
34 | ## Configuration
35 | 
36 | You can configure external-dns-ui via the following environment variables:
37 | 
38 | | Env Var Name                       | Description                                                                                                       | Default                |
39 | | ---------------------------------- | ----------------------------------------------------------------------------------------------------------------- | ---------------------- |
40 | | `EDUI_NAMESPACE`                   | The name of the namespace where your external-dns deployment is running                                           | `external-dns`         |
41 | | `EDUI_PREFERRED_URL_SCHEME`        | URL scheme to be used while generating links.                                                                     | `http`                 |
42 | | `EDUI_LOG_LEVEL`                   | Log level (see [python logging docs](https://docs.python.org/2/library/logging.html#levels) for available levels) | `INFO`                 |
43 | 
44 | ## Development
45 | 
46 | External-dns-ui is written in Python using the Flask framework for the backend and Fromantic-UI for the frontend.
47 | 
48 | Script `test/setup_test_environment.sh` builds & pushes the image, and runs the app in a Minikube test environment.
