NixOS also supports [declarative setup of the ntfy server](https://search.nixos.org/options?channel=unstable&show=services.ntfy-sh.enable&from=0&size=50&sort=relevance&type=packages&query=ntfy).
## macOS
The [ntfy CLI](subscribe/cli.md) (`ntfy publish` and `ntfy subscribe` only) is supported on macOS as well.
To install, please [download the tarball](https://github.com/binwiederhier/ntfy/releases/download/v1.28.0/ntfy_1.28.0_macOS_all.tar.gz),

The setup for Kubernetes is very similar to that for Docker, and requires a fairly minimal deployment or pod definition to function. There
are a few options to mix and match, including a deployment without a cache file, a stateful set with a persistant cache, and a standalone

Kustomize-based deployment with persistent storage and Traefik ingress
===
Kustomize allows for deploying templated configurations in easy way
### Kustomization
Create new folder, name it nfty and create kustomization.yaml within along all resources listed below.
Ingress is optional - you can skip this one if planning to expose service using different service type (hash it out from kustomization file)
```yaml
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
- ntfy-deployment.yaml # main deployment
- ntfy-svc.yaml # service connecting two pods together
- ntfy-pvc.yaml # pvc uset to store cache and attachment
- ntfy-ingress.yaml # ingress traefik
configMapGenerator: # will parse config from raw config to configmap,it allows for dynamic reload of application if additional app is deployed ie https://github.com/stakater/Reloader
- name: server-config
files:
- server.yml
namespace: TESTNAMESPACE # select namaespace for whole application
----
apiVersion: kustomize.config.k8s.io/v1beta1 #local resources
kind: Kustomization
resources:
- git@github.com:gituser/kustomize.git/kustomize/main/ #WIP when complete config will be stored in repo
namespace: TESTNAMESPACE # select namaespace for whole application
```
### ntfy-deployment.yaml
```yaml
apiVersion: apps/v1
kind: Deployment

```
### ntfy-pvc.yaml
Stores all in cache folder for event of the pod re-deployment
```yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: ntfy-pvc
spec:
accessModes:
- ReadWriteOnce
storageClassName: local-path # adjust storage if needed
resources:
requests:
storage: 1Gi
```
### ntfy-svc.yaml
Exposes pod to internal network of the cluster
```yaml
apiVersion: v1
kind: Service
metadata:
name: ntfy-svc
spec:
type: ClusterIP
selector:
app: ntfy-pod
ports:
- name: http-ntfy-out
protocol: TCP
port: 80
targetPort: http-ntfy
```
### ntfy-ingress.yaml
If cluster uses Ingress controller you have to deploy ingress to access application externally. It will not have TLS/SSL enabled so you have to deploy cert-manager and generate CA cert along certificate for service
```yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: ntfy-ingress
spec:
rules:
- host: ntfy.test #select own
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: ntfy-svc
port:
number: 80
```
### server.yml
```yaml
cache-file: "/var/cache/ntfy/cache.db"
attachment-cache-dir: "/var/cache/ntfy/attachments"
```
### Deploying from kustomization
Go one level up from folder where all resources were created and apply configuration
```bash
kubectl apply -k /nfty
```
