Installing Self Host NTFY On Linux Using Docker Container

The NTFY generally stands for “Notify”, a 100% free or opensource and created by Phillipp Heckel. REST-API-based publish-subscribe notification service (using simple HTTP PUT or POST requests) ; a utility that lets you send push notifications to your mobile phone or desktop via scripts from any computer.

It supports shell integration with popular Linux shells such as bash and zsh; It also offers features for process, emjoi, XMPP, Telegram, Instapush and Slack notification support.

Lets assumed that you have already installed and running Docker service in your system.

Install NTFY

● Host network
Executing the command line below will create a container for ntfy that uses host network:

docker run -d --name=ntfy --restart=always --network=host \ -v /opt/ntfy/cache:/var/cache/ntfy \ binwiederhier/ntfy serve --cache-file /var/cache/ntfy/cache.db

● User-defined bridge network
User-defined bridge network can be used for listening on different port using -p option

docker network create app-net docker run -d --name=ntfy --restart=always --network=app-net \ -p 8089:80 \ -v /opt/ntfy/cache:/var/cache/ntfy \ binwiederhier/ntfy serve --cache-file /var/cache/ntfy/cache.db

● Using docker-compose with non-root user and healthchecks enabled:

version: "2.3" 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: - 8089:80 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"]

Accessing And Testing NTFY

To access web UI, open a web browser and go to http://<HOST_IP_ADDRESS>:<PORT>

Once you have accessed the url and done the basic configuration based on the sample screenshot above, you may now publish topic or test message notification using sample scripts below (curl and php).

Example1: Command line (curl)

curl \ -d "HELLOWORLD PINOYLINUX.ORG" \ https://localhost:8089/RockITPinoyNotifications

Example2: PHP

file_get_contents('https://localhost:8089/RockITPinoyNotifications', false, stream_context_create([ 'http' => [ 'method' => 'POST', // PUT also works 'header' => 'Content-Type: text/plain\r\n' . 'content' => 'HELLOWORLD PINOYLINUX.ORG' ] ]));

Example3: RSYNC

rsync -rvapl --numeric-ids --progress [email protected]/home/admin/* . \ && zfs snapshot ... \ && curl -H prio:low -d "Server backup succeeded" ntfy.sh/adminfolderbackups \ || curl -H tags:warning -H prio:high -d "Server backup failed" ntfy.sh/adminfolderbackups
