Automated server reboot

[humptydumpty]

@potemkin_ai said in Automated server reboot:

I probably could, but what's the point?

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.

[potemkin_ai]

@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.

@potemkin_ai We can try it step by step:

docker inspect --format '{{ .Config.Env }}' mail | tr ' ' '\n' | grep CLOUDRON_RELAY_TOKEN
CLOUDRON_RELAY_TOKEN=71df0df31cb3512bfe8fad02561cda813c6db4f94d2cb7137bbc162e9c1775058887606e5c37b8013df08498e3c609f52f1147cbb5a9ad96b7f4c5e848a235c44569510c37ab25eaaa67d50641481843cad93c7221893a869e34411d3e8edf6f55e3b7d8fa3ab1ce7632e0fd3bf65a8050549fe4d43d50e3ddb1c2c6b0eaca0d
root@upgrade-test:~# echo "71df0df31cb3512bfe8fad02561cda813c6db4f94d2cb7137bbc162e9c1775058887606e5c37b8013df08498e3c609f52f1147cbb5a9ad96b7f4c5e848a235c44569510c37ab25eaaa67d50641481843cad93c7221893a869e34411d3e8edf6f55e3b7d8fa3ab1ce7632e0fd3bf65a8050549fe4d43d50e3ddb1c2c6b0eaca0d" | wc -c
257

So, mine is also 257 characters long.

# docker inspect --format '{{ .NetworkSettings.Networks.cloudron.IPAddress }}' mail
172.18.0.3

The final command:

# swaks -s 172.18.0.3 -p 2525 --au no-reply@cloudron.space --ap "71df0df31cb3512bfe8fad02561cda813c6db4f94d2cb7137bbc162e9c1775058887606e5c37b8013df08498e3c609f52f1147cbb5a9ad96b7f4c5e848a235c44569510c37ab25eaaa67d50641481843cad93c7221893a869e34411d3e8edf6f55e3b7d8fa3ab1ce7632e0fd3bf65a8050549fe4d43d50e3ddb1c2c6b0eaca0d" -f no-reply@cloudron.space -t 'test@cloudron.io' --h-Subject "Test mail"

Can you paste your entire sequence like above? Note that it has to be no-reply@yourdomain.com for both the --au argument and the -f argument.

[girish]

Also, maybe someone else can try the above too Just to be sure I am not missing something obvious.

[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:

@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.

@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!
