# Installing ntfy
The `ntfy` CLI allows you to [publish messages](publish.md), [subscribe to topics](subscribe/cli.md) as well as to
self-host your own ntfy server. It's all pretty straight forward. Just install the binary, package or Docker image,
configure it and run it. Just like any other software. No fuzz.
!!! info
The following steps are only required if you want to **self-host your own ntfy server or you want to use the ntfy CLI**.
If you just want to [send messages using ntfy.sh](publish.md), you don't need to install anything. You can just use
`curl`.
## General steps
The ntfy server comes as a statically linked binary and is shipped as tarball, deb/rpm packages and as a Docker image.
We support amd64, armv7 and arm64.
1. Install ntfy using one of the methods described below
2. Then (optionally) edit `/etc/ntfy/server.yml` for the server (Linux only, see [configuration](config.md) or [sample server.yml](https://github.com/binwiederhier/ntfy/blob/main/server/server.yml))
3. Or (optionally) create/edit `~/.config/ntfy/client.yml` (for the non-root user) or `/etc/ntfy/client.yml` (for the root user), see [sample client.yml](https://github.com/binwiederhier/ntfy/blob/main/client/client.yml))
To run the ntfy server, then just run `ntfy serve` (or `systemctl start ntfy` when using the deb/rpm).
To send messages, use `ntfy publish`. To subscribe to topics, use `ntfy subscribe` (see [subscribing via CLI](subscribe/cli.md)
for details).
## Linux binaries
Please check out the [releases page](https://github.com/binwiederhier/ntfy/releases) for binaries and
deb/rpm packages.

```
## Arch Linux
ntfy can be installed using an [AUR package](https://aur.archlinux.org/packages/ntfysh-bin/). You can use an [AUR helper](https://wiki.archlinux.org/title/AUR_helpers) like `paru`, `yay` or others to download, build and install ntfy and keep it up to date.
```
paru -S ntfysh-bin
```
Alternatively, run the following commands to install ntfy manually:
```
curl https://aur.archlinux.org/cgit/aur.git/snapshot/ntfysh-bin.tar.gz | tar xzv
cd ntfysh-bin
makepkg -si
```
## NixOS / Nix
ntfy is packaged in nixpkgs as `ntfy-sh`. It can be installed by adding the package name to the configuration file and calling `nixos-rebuild`. Alternatively, the following command can be used to install ntfy in the current user environment:
```
nix-env -iA ntfy-sh
```
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/v2.2.0/ntfy_2.2.0_macOS_all.tar.gz),
extract it and place it somewhere in your `PATH` (e.g. `/usr/local/bin/ntfy`).
If run as `root`, ntfy will look for its config at `/etc/ntfy/client.yml`. For all other users, it'll look for it at
`~/Library/Application Support/ntfy/client.yml` (sample included in the tarball).
```bash
curl -L https://github.com/binwiederhier/ntfy/releases/download/v2.2.0/ntfy_2.2.0_macOS_all.tar.gz > ntfy_2.2.0_macOS_all.tar.gz
tar zxvf ntfy_2.2.0_macOS_all.tar.gz
sudo cp -a ntfy_2.2.0_macOS_all/ntfy /usr/local/bin/ntfy
mkdir ~/Library/Application\ Support/ntfy
cp ntfy_2.2.0_macOS_all/client/client.yml ~/Library/Application\ Support/ntfy/client.yml
ntfy --help
```
!!! info
There is a [GitHub issue](https://github.com/binwiederhier/ntfy/issues/286) about making ntfy installable via
[Homebrew](https://brew.sh/). I'll eventually get to that, but I'd also love if somebody else stepped up to do it.
Also, you can build and run the ntfy server on macOS as well, though I don't officially support that.
Check out the [build instructions](develop.md) for details.
## Windows
The [ntfy CLI](subscribe/cli.md) (`ntfy publish` and `ntfy subscribe` only) is supported on Windows as well.
To install, please [download the latest ZIP](https://github.com/binwiederhier/ntfy/releases/download/v2.2.0/ntfy_2.2.0_windows_x86_64.zip),
extract it and place the `ntfy.exe` binary somewhere in your `%Path%`.
The default path for the client config file is at `%AppData%\ntfy\client.yml` (not created automatically, sample in the ZIP file).
Also available in [Scoop's](https://scoop.sh) Main repository:
`scoop install ntfy`
!!! info
There is currently no installer for Windows, and the binary is not signed. If this is desired, please create a
[GitHub issue](https://github.com/binwiederhier/ntfy/issues) to let me know.
## Docker
The [ntfy image](https://hub.docker.com/r/binwiederhier/ntfy) is available for amd64, armv6, armv7 and arm64. It should
be pretty straight forward to use.
The server exposes its web UI and the API on port 80, so you need to expose that in Docker. To use the persistent
[message cache](config.md#message-cache), you also need to map a volume to `/var/cache/ntfy`. To change other settings,
you should map `/etc/ntfy`, so you can edit `/etc/ntfy/server.yml`.
!!! info
Note that the Docker image **does not contain a `/etc/ntfy/server.yml` file**. If you'd like to use a config file,
please manually create one outside the image and map it as a volume, e.g. via `-v /etc/ntfy:/etc/ntfy`. You may
use the [`server.yml` file on GitHub](https://github.com/binwiederhier/ntfy/blob/main/server/server.yml) as a template.
Basic usage (no cache or additional config):
```
docker run -p 80:80 -it binwiederhier/ntfy serve
```
With persistent cache (configured as command line arguments):
```bash
docker run \
-v /var/cache/ntfy:/var/cache/ntfy \
-p 80:80 \
-it \
binwiederhier/ntfy \
serve \
--cache-file /var/cache/ntfy/cache.db
```
With other config options, timezone, and non-root user (configured via `/etc/ntfy/server.yml`, see [configuration](config.md) for details):
```bash
docker run \
-v /etc/ntfy:/etc/ntfy \
-e TZ=UTC \
-p 80:80 \
-u UID:GID \
-it \
binwiederhier/ntfy \
serve
```
Using docker-compose with non-root user and healthchecks enabled:
```yaml
version: "2.1"
services:
ntfy:
image: binwiederhier/ntfy
container_name: ntfy
command:
- serve
environment:
- TZ=UTC # optional: set desired timezone
user: UID:GID # optional: replace with your own user/group or uid/gid
volumes:
- /var/cache/ntfy:/var/cache/ntfy
- /etc/ntfy:/etc/ntfy
ports:
- 80:80
healthcheck: # optional: remember to adapt the host:port to your environment
test: ["CMD-SHELL", "wget -q --tries=1 http://localhost:80/v1/health -O - | grep -Eo '\"healthy\"\\s*:\\s*true' || exit 1"]
interval: 60s
timeout: 10s
retries: 3
start_period: 40s
restart: unless-stopped
```
If using a non-root user when running the docker version, be sure to chown the server.yml, user.db, and cache.db files and attachments directory to the same uid/gid.
Alternatively, you may wish to build a customized Docker image that can be run with fewer command-line arguments and without delivering the configuration file separately.
```
FROM binwiederhier/ntfy
COPY server.yml /etc/ntfy/server.yml
ENTRYPOINT ["ntfy", "serve"]
```
This image can be pushed to a container registry and shipped independently. All that's needed when running it is mapping ntfy's port to a host port.
## Kubernetes
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 persistent cache, and a standalone
unmanned pod.
=== "deployment"

Configuration is relatively straightforward. As an example, a minimal configuration is provided.
=== "resource definition"
```yaml
apiVersion: v1
kind: ConfigMap
metadata:

# Template: https://github.com/binwiederhier/ntfy/blob/main/server/server.yml
base-url: https://ntfy.sh
```
=== "from-file"
```bash
kubectl create configmap ntfy --from-file=server.yml
```
## Kustomize
ntfy can be deployed in a Kubernetes cluster with [Kustomize](https://github.com/kubernetes-sigs/kustomize), a tool used
to customize Kubernetes objects using a `kustomization.yaml` file.
1. Create new folder - `ntfy`
2. Add all files listed below
1. `kustomization.yaml` - stores all configmaps and resources used in a deployment
2. `ntfy-deployment.yaml` - define deployment type and its parameters
3. `ntfy-pvc.yaml` - describes how [persistent volumes](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) will be created
4. `ntfy-svc.yaml` - expose application to the internal kubernetes network
5. `ntfy-ingress.yaml` - expose service to outside the network using [ingress controller](https://kubernetes.io/docs/concepts/services-networking/ingress-controllers/)
6. `server.yaml` - simple server configuration
3. Replace **TESTNAMESPACE** within `kustomization.yaml` with designated namespace
4. Replace **ntfy.test** within `ntfy-ingress.yaml` with desired DNS name
5. Apply configuration to cluster set in current context:
```bash
kubectl apply -k /ntfy
```
=== "kustomization.yaml"
```yaml
apiVersion: kustomize.config.k8s.io/v1beta1
