I missed that introduction so much in many of the previous tutorials i watched. Simple ,clear and very useful in order to understand the whole thing.

[@QualtarVideo]

Tony, I've been trying to get something like this working for about 2 week though it feels like a century. I must have seen 30 'How to' videos. Your video is the only one that actually works. I'm so happy I found your tutorials.

[@ahmedosman1020]

This is by far the best video out there to show how to deploy a Flask app!
Tony you are the GOAT man
Respect

[@user-cc2yd2cc3c]

Thank you！
There are no tutorial videos like yours in Japan.
I was in trouble.
However, I was able to solve some problems by watching your video.
thank you!

[@msatashi_daily]

hai, Tony thanks for your videos. but I want to ask how to change the website after deployment? I've struggling with it.

[@techatival]

Nice, thank you!

[@vman049]

Thanks for making the tutorial. Could you please share the link to part 1?

[@WaldoTheWombat]

does anyone know how to deploy a flask app that uses web sockets? because I just finished deploying my app watching a deployment tutorial by Tech with Tim, but it seems that the sockets don't work there:
'Cannot obtain socket from WSGI environment.'

[@olaoka-ih9ej]

I am using a centOS system and it gives me a permissions error when I want to run the peak service I checked if my user has the necessary permissions and the group it belongs to and it keeps giving me the same permission denied error

[@marcelltoth9737]

Thanks!

[@slurpeesauce1750]

THANK Y(OU
HOURS AND HOURS I NEEDED THIS

[@elliotsilveira30]

If I am setting this up all on a local device how can I get flask to host my public ip and not my local ip???

[@thepramodgeorge]

How do you do your video backgrounds? I can't figure it out! 😅

[@zhulipa]

Thank you

[@taneliharkonen2463]

What do I do in the /etc/nginx/nginx.conf? How do I make nginx read those sites-available config files?

[@xleage]

[@freepluralism6652]

Is it needed or asviable to remove root permission granted to the created User once the Website is published?

[@WillYouVid]

This is nice and teaching me a lot, thx! Your content is awesome, complete and straight to the point. But at the last minute I had an OCD attack triggered by the chmod 775, the sysadmin in me would have chown the sock file to the www-data user. Would it really have been safer to do so or is it just a stupid quirk of mine?

[@donaldduck1073]

if a tutorial contains only positive responses, like this one then you can assume that the author deletes critical hints. Like this one that has 2 errors in it. My comment got deleted.

[@fernandocoot9359]

the peak.sock file has to be in the directory app?

[@RabeloHigor]

How can I update the app after deployment? I have modified the Python code, but I am unsure of the steps required to make the updated version go live.
Thank you for this video. It is really amazing, bro!

[@fullstackoverflow-ct3bz]

I have set guncorn with certificate and key to make it https. but after running gunicron the API cannot be accessed. is there any reference for gunicorn https?

i follow ur tutorial now 2 times but every time after i setup nginx as proxy i only get the welcome site from nginx but not my flask app do u have a idea why this is?

The same problem! Did you solve it?

[@verainsardana]

8:45 can someone explain why are we binding gunicorn to socket instead of address?

[@verainsardana]

I found the reason, it is because socket is much faster and more secure. Hope this helps

[@sneaksneak6522]

Thank you for updating us. Would you be able to clarify, is the socket made implicitly when creating the service file? @@verainsardana

[@verainsardana]

@@sneaksneak6522 the socket is created when the service is in running state

[@wertuxhd6201]

After permissions given, I still get 502 Gateway error.

[@TonyTeachesTech]

Try this th-cam.com/video/hYVriHb43wU/w-d-xo.html

[@cartulinito]

@@TonyTeachesTech That is for PHP

[@cartulinito]

Add these 2 lines under "location" , right below "proxy_pass..." in your /etc/nginx/sites-available/file
.conf:
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
That did it for me.
Don't forget to stop nginx before, and after you edit the file, remove the symbolic link under /etc/nginx/sites-enabled/ and create it again from /etc/nginx/sites-available/yourfile.conf

Check if you already have gunicorn running
> ps aux | grep gunicorn
Then kill the old process

I wish someone would have told me when I was learning Flask to learn Django instead.

[@shizhouliu8912]

Why do you think Django is better then Flask based on your experience?

[@GiantsOnTheHorizon]

@@shizhouliu8912 You always hear that Flask is "easier to get started with." This may be true if you're doing a one page website. However, Django isn't all that much harder and it has built-in security, a built-in admin interface, etc. In Flask I kept having to tack new things on that were already incorporated into Django. This quickly begins to get messy and time consuming.

[@shizhouliu9212]

@@GiantsOnTheHorizon Good to know. Thanks

[@WillYouVid]

@@GiantsOnTheHorizon it´s a matter of phylosophy, Django is heavier, Flask is more modular, it´s like saying oh wow, I wish I knew about Debian instead of using Arch, Debian has it all and with Arch I have to add all of the kernel modules one by one. None is better than the other IMHO, what´s important is to know that both exist and what each can give you.
Django is modular too depending on what you mean by it. I hope what I said makes sense to you.

[@GiantsOnTheHorizon]

@@WillYouVid Sure. I guess my main point was that it takes longer to have to figure out which modules to add on vs having the batteries included. Especially if you’re just starting out.
