Very big thumbs up for using gunicorn and not default flask server as others. Nice!

[@prettyprinted]

Definitely the more appropriate option. Thanks for watching!

[@sinancetinkaya]

thumbs up for centering a text in CSS :)

[@prettyprinted]

haha yeah I figured I shouldn't be so lazy to center my basic header text.

[@skyricho]

Awesome tutorial. Exactly what I was looking for!

[@EddiKh]

Is there a tutorial on security configurations and firewall? and great video! exactly what I was looking for

[@dmbrv]

Awesome video. I didn't know that Caddy will automatically get a sign certificate from Let's Encrypt

[@prettyprinted]

Yeah Caddy makes things really simple. Thanks for watching.

[@tadashi-kun4820]

It worked like a charm. Runs perfectly fine. Thank you very much!

[@benjohnson5897]

Thanks! Very useful, but it reminded me why i simply code and deploy on Replit. I dont have enough patience for all this stuff! 😂

[@jazz8932]

after installing caddy and going to the IP address I see no response?

[@mahboob82]

Well organised contents! Thanks for making it easy for us.

Can you please add the notes to your github repository for the video? Unfortunately TH-cam shortened the URL in your two lines making it difficult to copy and paste. I had to click on the two URL to determine what it should have been to continue.

Here you go: github.com/PrettyPrinted/youtube_video_code/tree/master/2023/07/17/How%20to%20Deploy%20a%20Flask%20App%20to%20a%20Linux%20Server%20with%20a%20Domain%20Name

[@honzabe]

@@prettyprinted I might be missing something but I do not see the notes the OP requested in the document you linked. I also think they could be useful - TH-cam shortened URLs in your notes here so the commands copied from TH-cam do not work unless you reconstruct how they looked like before the shortening. Some people might get confused by it (ehm, "some people", like me).

Hello, i have an oracle free tier instance running ubuntu with some websites (php) hosted (with their own domains) by cloudpanel. If i do exactly like you did. My other websites will stop working?

[@TaylorNelson1]

Wow so easy. Is gunicorn good enough, by itself, that I do not need to use other hacks via apache and wsgi?

[@asmasaduf6257]

when i did gunicorn app:app Iget this error "from gunicorn import util
File "E:\sid\TF-Image-Classifier-API\venv\Lib\site-packages\gunicorn\util.py", line 8, in
import fcntl
ModuleNotFoundError: No module named 'fcntl'"

[@jakobseitz1176]

note: the curl commands didnt work for me, but caddy still worked fine. But I also used a v-server from netcup

[@iconjack]

the curl commands in the description got mangled by youtube-you'll have to type them in from the terminal on the screen

[@rish9422]

would be this possible on Azure?

[@eboyd53]

Thanks for the video and instructions. BTW, you could use ``pkill gunicorn`` to kill the application if the pkill command exists.

[@prettyprinted]

Thanks, I should have checked if pkill was there. Thanks for watching!

[@dgoek]

Thank you so much this is very useful; I working on my website this contain a payment with paypal and this is working on visual studio code, however when I upload to lightsail server this is not working, I receive an error regarding authetication, however I thinks this is related with networking, maybe I am missing some configuration, any idea ?

[@y2ksw1]

Is there any reason you are using caddy instead of nginx?

[@prettyprinted]

I think it's a lot easier to work with. I also like the auto SSL.

[@infossil]

thank you, worked perfect

[@VictorsTravelvLog]

exactly what i needed!

[@WaldoTheWombat]

How Anthony, will this work with a Flask app that uses web sockets?

[@marcosoliveira8731]

Huuuuge thanks man!

[@shaunsharon6849]

What about in Windows?

[@tasmaniandaemon]

why not nginx

[@curtking70]

Thanks!

[@prettyprinted]

You're welcome! Thanks for the super thanks!

[@Kennethlumor]

Sir thank you for this tutorial. Please I request from you to make a video on how to connect Google auth to flask app. Because as am talking to you right now Google has taken or remove allow third party integration. That is very hard for me to do now. So please and please I'm begging you in the name of God to make a video on that.

[@prettyprinted]

I'll look into Google auth. Thanks for watching!

[@HamzahAl-Hamadani]

i love you

[@anony88]

Why does my comments keep getting removed on youtube.. 😑

[@redsword7192]

hehe

[@kenisi_thedevilonhigh]

yep, the video creator rabbit holed over monetary capital above $0/second. I don't buy it
