Automated server reboot

[fbartels]

@girish I can confirm that the following works for me:

swaks -s `docker inspect --format '{{ .NetworkSettings.Networks.cloudron.IPAddress }}' mail` -p 2525 --au no-reply@9wd.eu --ap `docker inspect --format '{{ .Config.Env }}' mail | tr ' ' '\n' | grep CLOUDRON_RELAY_TOKEN | sed 's/^.*=//'` -f no-reply@9wd.eu -t 'test@9wd.eu' --h-Subject "Test mail"

[potemkin_ai]

@fbartels @girish something is wrong here..

Note that it has to be no-reply@yourdomain.com for both the --au argument and the -f argument.

--au no-reply@9wd.eu ... -f no-reply@9wd.eu

those two contradicts to each other...

@fbartels does this command actually deliver an e-mail to test@9wd.eu?

[potemkin_ai]

@girish sure, here it is:

root@anabelle:~# docker inspect --format '{{ .Config.Env }}' mail | tr ' ' '\n' | grep CLOUDRON_RELAY_TOKEN

@potemkin_ai the no-reply@cloudron.space in the swaks command is not correct. you have to replace this with no-reply@yourdashboarddomain.com (in 2 places in the command line)

@potemkin_ai said in Automated server reboot:

@fbartels does this command actually deliver an e-mail to test@9wd.eu?

Yes, just like Girish said, you only need to make sure that your from (the -f parameter) and the login user (the -au parameter) match your main cloudron domain. The -t is the parameter for the recipient, this can be on the cloudron system or another mailbox.

[potemkin_ai]

@fbartels @girish , got it working now - thank you very much!!

Can you share your full script? Thanks!

[potemkin_ai]

@necrevistonnezr sure, scripted and published:

• https://github.com/Potemkin-Co/quickies/blob/main/reboot_ubuntu_if_required.sh - do the server reboot, if it was requested by anything earlier, calls mail script before the reboot
• https://github.com/Potemkin-Co/quickies/blob/main/send_mail_with_cloudron.sh sends an e-mail

Be sure to change your e-mail and path to the mail script at the first script.

[necrevistonnezr]

@potemkin_ai Thanks!

[IniBudi]

@potemkin_ai is the script still relevant on the latest version of Cloudron?

[d19dotca]

@girish , maybe this is a good feature for 9.1?

[potemkin_ai]

@inibudi , it is; but I've optimized it down to a single crontab entry:

crontab -l
48 2 * * * /bin/sh -c '[ -f /var/run/reboot-required ] && sudo shutdown -r now'
