Automated server reboot

You can use swaks like this:
First get the IP of the mail container:
# docker inspect --format '{{ .NetworkSettings.Networks.cloudron.IPAddress }}' mail 172.18.0.2Then, you need the "token" which is the auth to send mails:
# docker inspect --format '{{ .Config.Env }}' mail | tr ' ' '\n' | grep CLOUDRON_RELAY_TOKEN | sed 's/^.*=//' 9e000daa7ba34f29ed975d54b880f30794c2cebcd795f124Now, you can send using swaks (replace IP and token below):
# swaks -s 172.18.0.2 -p 2525 --au no-reply@cloudron.space --ap 9e000daa7ba34f29ed975d54b880f30794c2cebcd795f1241 -f 'no-reply@cloudron.space' -t 'test@cloudron.io' --h-Subject "Test mail" -

I love automation and one-liners, so I guess it could be all combined into one command:

@potemkin_ai maybe we can take a closer look for the next release. So far the automatic reboot wasn't a pressing issue, so if you need this anytime soon, I guess a simple bashscript doing all this for you will be best. Would be nice if you could share it here, since I currently wouldn't even know how to figure out if any of the packages would have failed to notify.
Also we do not have any generic email route to just send out custom text to the admins via the mail configuration since there was no use-case for this either.
Further with Ubuntu 20 and ongoing I think there is also a possibility to avoid reboots altogether for kernel updates, so maybe this would be a better solution in the long run anyways?
@nebulon did you mean manual configuration for that service?

@potemkin_ai yes I was referring to this, but I haven't really had a deeper look into that topic yet and to which extent this is free or a paid addon in ubuntu.
@nebulon got it, makes sense, but from what I see it requires extra configuration anyway and most probably won't be available out of the box, so an automatic reboot would be of great help; especially for the next two years while 18.04LTS is supported

@girish thank you.
I re-did all the steps manually as per your original message and got the same error.
The only major difference between your and my setup - it's token length - it's 257 characters long in my case.
Any clue?

My primary concern remains token, because mine is muuuuch longer than yours (hope it sounds right in the context of token comparison....), and authentication is failing right after mail service gets it.
Any way to troubleshoot that?

@potemkin_ai Can't you use something like "Uptime Kuma" to monitor site status instead?
It has "Notifications via Webhook, Telegram, Discord and email (SMTP)" so it should work for your use-case.

@humptydumpty I probably could, but what's the point?
There is a working solution from Cloudron, we just need to figure out where exactly it's failing. -

It's two birds with one stone. You end up having app/site monitoring too but I'm not against your method. I'm just suggesting alternatives for consideration.

@humptydumpty thank you, but my server is already monitored - both from inside (with the monitoring agent) and from the outside (via http ping), so my only task now, it’s to ensure I can drop an e-mail notification to myself, so that if my monitoring shows that the server is not available, I can see an e-mail next to the monitoring saying, that the server was going to reboot itself, which will help me to understand and fix that in no time, instead of guessing what could went wrong.
