Creating a Flask Web Server in EC2 on the AWS Free Tier from scratch!

I show how to deploy a Python Flask app on an EC2 instance in the AWS free tier. I walk through each step that is needed to configure security group rules and prepare the Ubuntu OS with gunicorn and nginx to successful host your website.
To see the commands I ran in this video, go to this link: / step-by-step-visual-gu...

Only halfway through and this has already been one of the most helpful programming tutorials I've ever watched. Wow, good job skipping over all the useless crap, like telling me how to sign up for an AWS account for 5 minutes, while expanding on the stuff that's actually important to know, like what a worker is (never knew that). Thank you!

[@mithson]

[@gilbertoyarritu1326]

@@TheTORTA31 There could be many things affecting wether it works or not. For starters are you trying it in a network that may block some connections. I first tried it in my college network and it didn't work. Also make you sure yo have all the right permissions

[@xuechuanmi5345]

Hey there, Hope you are having a wonderful life! Your video and blog are super helpful! I have one question: why is port 8000 working from outside? I didn't see you set it open in the aws console. Without nginx, will the server be accessible to public browsers? I understand the reverse-proxy but, how is 8000 open to the outside? sorrt for the naive question, been a noob in this area XD thanks!

you really did well. But i have a question that is when you bind nginx with this app only, what if i have multiple scripts and want to run those within the same server?

You're a freaking wizard bro let's be friends 😂😂😂 I got ideas dawg 😂

[@njbshah]

kindly make a tutorial on doing exactly same but on Windows EC2 instance

[@HenkLeerssen]

Concise.. only one thing. The "systemctl" command is not available with your tutorial (I use Frankfurt AWS node).. you can work your way around things with "service" command... but that does not restart things automatically after a reboot...

[@DrexSux]

I love the video, thank you so much! I am having trouble with the src/link tags on HTML though; it seems any ref or href won't link (might be due to relative pathing) so I'm unable to display any JS or CSS or static images. Does anyone have any insight on why this might be/the correct syntax? Thank you in advance!

[@aguilarstephenjoaquing.1831]

thank you for helping me, but i've just changed my source code, then i restarted gunicorn and nginx, why still i get the previous one when i curl it in localhost:8000 gunicorn, but if i curl in localhost:5000 when im running it on dev server, i get the changed one.

How does the service work, if it needs flask. I see that you provide path for gunicorn launch command from the created venv, but how does service know to use the actual venv?

Where are logs written to when running flask like this?

Technically don't need nginx, can just start flask/gunicorn on port 80? (For demo)

how to push new code to flask app in order to reflect it on our web app as I tried updating the code of hello world using git push and also tried restarting nginx server still its showing old app on server

for that you need to restart you gunicorn service use this command to restart your gunicorn service: sudo systemctl restart gunicorn

[@beongky]

Thanks for the useful tutorial. Just one question here... After restarting the instance, it doesn't work anymore, should we have to start manually any of these services?

[@VincentStevenson]

Yes - depending on how you’ve configured the OS, the services need to be restated. Linux does have ways of making services run automatically when the system boots.

My father and I are having trouble connecting to our EC2 instance via SSH, and also are attempting to connect to it to send files via SCP. Seems like passing our keys in with the SSH command doesn't work, despite running the same command the Amazon supplies us with (the SSH command). We're also trying to set up Remote SSH to our EC2 instance using VSCode's extension for Remote SSH by Microsoft. Any tips you can give us? Much appreciated!

[@VincentStevenson]

I would double check the security group to make sure ssh traffic is allowed from anywhere on port 22 for the instance.

[@Alpheamus]

@@VincentStevenson We had an unfortunate problem where, once we had gotten fed up with the pem/ppk key files not working, we opened it to be access via password and user, and we believe someone used a web spider, discovered us, and hacked our instance because it slowed down tremendously and continuously crashed when we attempted to do anything. We started a new one following your tutorial once again and managed to get our pem/ppk key files to work properly. To anyone in the future, definitely don't open the servers for use with user/pass, and download VSCode Remote SSH extension and connect it to the instance. It makes working on it so much simpler. Thanks for your tutorial, Vincent. Looking forward to more.
