ntfy.sh : self-hostable notifications

[timconsidine]

https://ntfy.sh

ntfy (pronounce: notify) is a simple HTTP-based pub-sub notification service. It allows you to send notifications to your phone or desktop via scripts from any computer, entirely without signup, cost or setup. It's also open source if you want to run your own.

Really simple notifications for scripts, server status etc.

curl -d "Backup successful 😀" ntfy.sh/mytopic

If self-hosted, obviously change the ntfy.sh to your own domain.

[fbartels]

Notify.sh is indeed quite a cool project and has also seen good growth over the last few months.

Depending on the use case I prefer to rely on third parties for checks/notifications. What good is a chat or email notification if my mail or chat server are down as well

Slightly more complicated curl, but this posts a message into a telegram message:

curl https://api.telegram.org/bot$telegramApi/sendMessage -d chat_id=$telegramChat -d text="Backup successful 😀"

[timconsidine]

@fbartels neat !
thank you - didn't know Telegram had this 'direct post'

[robi]

@timconsidine Yeah, if you install our Server Monitor App, it also has that feature to send alerts via TG, Discord, etc..

[robi]

@fbartels if you have multiple cloudrons you could have each monitor each other.

alternatively you could reverse monitor a single one by having something elsewhere consume liveness messages/notifications so you know when they stop.

Easier to just use one of the free monitoring services to check your services externally.

our Server Monitor App

Which app is that exactly?

@robi said in ntfy.sh : self-hostable notifications:

each monitor each other.

yeah, if you want to be serious about monitoring then it should run with a different provider and in a different region than the rest of your stack. Or even better pay someone else to host a geo distributed monitoring for you.

For my own use case Uptime Kuma is quite sufficient and can also send notification via Telegram.

[timconsidine]

I have made a first bash at packaging ntfy.sh for cloudron.

Some issues remain but seems useable.
Will be testing further.

Available at https://git.cloudron.io/timconsidine/ntfy-for-cloudron

[timconsidine]

Use case example :
To get a daily report on status of a VPS (non-cloudron), a bash script is run by cron :

#!/bin/bash
echo 'MyDocker' > /root/ntfy-msg.txt
date >> /root/ntfy-msg.txt
if [ -f /var/run/reboot-required ]; then
 cat /var/run/reboot-required >> /root/ntfy-msg.txt
fi
df -h / >> /root/ntfy-msg.txt
docker container ls --format 'table {{.Status}}\t{{.Names}}' >> /root/ntfy-msg.txt
curl ntfy.sh/xxxxxxx -T /root/ntfy-msg.txt

which gives this :

@timconsidine you are on a roll, I will look into both your packages this week. Thanks!

[girish]

@timconsidine do you think you can add a LICENSE file to both your repos? We just use MIT license for our other packages, but any open source license will do.

[timconsidine]

@girish yep sure thing, will do.

[LoudLemur]

@timconsidine Thank you for your packaging efforts. You must be becoming better and better at it. I hope you become so good at it soon that it becomes a cinch for you to do most things!

[timconsidine]

@LoudLemur you're too kind. I'm an amateur, just doing the easy stuff, but learning. More productive than sudoku to ward off dementia

[timconsidine]

@girish added LICENCE
I thought best to copy over the licences from the original author repo.
Wouldn't want to say anything different and offend them.
If that's not best approach, do say.

Came searching for ntfy.sh and was not disappointed! I've been keeping track of this project's progress with their updates on r/selfhosted and it looks like they just released the first version of the iOS app!

Is this image being kept up to date with releases? I think the server.yml file can be adjusted to automatically grab the CLOUDRON_APP_ORIGIN env variable so the user doesn't have to update it after install. Would love to see this published since it seems like it's already pretty close to the finish line. Let me know if I can help with getting this across!

[timconsidine]

@thetomester13 : I haven't kept it up to date, but I will do so in my repo.

Good news on the iOS app - will check it out

EDIT : Just checked my self-package repo and I see that it just runs apt install ntfy into the base container.
So for fresh installs you get the latest deployed apt package.

For updates of previously deployed instances, I am not sure. Will try and learn.

[timconsidine]

@thetomester13 good point on the base_url

Feel free to do a proper packaging.
Mine was a bit of a hack for my own purposes.

Would be great to see a proper version in the App Store.
It's so just darned useful.
I get morning reports from a variety of servers and machines. and also enquiries to things like Hetzner Storage Box, Scaleway and Wasabi so I can monitor status in 5 mins over a coffee.

[ericdrgn]

Would be excited to see this in the cloudron store proper myself! Thanks for all the work on it @timconsidine, good enough for now

For anyone wondering it makes a great notification backend (on Android at least as that was all I tested) in coordination with self hosted matrix/element. The Android app has an option to use it as the backend, it doesn't change anything functionally about notifications but it does keep from using FCM which is the best part imo.
