Very awesome tutorial!! I have checked over many online docs or videos regarding dockerizing the flask & nginx application. Yours is by far the most easy-to-follow and clearly structured one. Thanks!
on par with the legend Corey Schafer here. Really helped me nail the overall idea and implementation of docker-compose. Will be donating to you once I get a job lol
Hey man, thanks for the great tutorial. It helped at lot! For the next video, could you please explain how to add a Redis container to act as a queue for the requests coming into the web app?
This is GREAT. You have explained what a developer would actually do step by step to get an app to containerization and production. I can now containerize my applications logically and simply in a very structured manner. THANK YOU! I will now watch the rest of your videos. Really appreciate your work here. Please keep sharing.
this is not an appropriate video for learning towardsdatascience.com/how-to-deploy-ml-models-using-flask-gunicorn-nginx-docker-9b32055b3d0 try this link
thanks for this Tutorial it has helped me a lot. What would I need to change if I wanted to run the Nginx container and flask container on separate machines? I assume modifying the nginx.conf file to point at the ip of the flask machine, would uwsgi_pass still be uswgi_pass flask:8080 though?
Thanks Julian, I watch once and then another time your videos, it help me so much with because they are very informative and fundamentals, I tried to run this example and I found an issue with uwsgi installation in python3.8, after read many blogs finally found a workaround, we can install the module pyuwsgi, please continue with your videos
Wasted four hours of my life on this: and worst part is he does not have a github (what kind of developer does not have a github?) Followed video and tutorial to a T flask | Traceback (most recent call last): flask | File "run.py", line 1, in flask | from app import app flask | ImportError: cannot import name 'app' from 'app' (unknown location)
For me that was an issue: --- no python application found, check your startup logs for errors --- Solution: instead of -> "wsgi-file = main.py" used this -> "module = main:app" in the "ini" file.
Hi Julian, thanks a lot for sharing this insightful vid. Could you also please show how this could be done with an additional database service and a front end service? Say a Postgresdb folder and a react folder with typescript code in it? Thanks !
I don't know the answer mate but I just want to tell you that he had stop uploading new videos and he's not going to answer your question. You can see his last upload was 3yrs back. May be he just quitted the TH-cam because of poor response or maybe something else. But his videos are really helpful.
@@assaultx5677 well thank you, I solved the issue (with lot of effort), however the good practice the way that is presented in the video (using separate images and containers)
17:50 "Building an image" was actually correct. You first build an image and then create and run a container based on that image. Great tutorial. Thank you Julian
Nice tutorial but the music is not necessary and really takes away from the entire video since you constantly hear a little "plink" all the way through.
i had the same problem, i solved that problem without copy the env folder. Just install everything globally on the container, linux can install uwsgi, but windows
Hi Julian, Great Tutorial. Do i really need to add the nginx part if deploying to a Synology NAS which already has nginx web server and reverse proxy set up on? Thanks Tim
sigh, good tutorial, very good presentation and tone but, like a lot of enthusiasts another assumption that Linux is the default coding environment, it isn't. Nowhere did you mention that UWSGI is not installable on windows. Remember that LOTS of government and business environments DO NOT use Linux on the desktop, they might use Linux servers but not desktops.
Wow. So thorough and easy to follow. Thank you!!! Questions: (1) How do we differentiate apps? Am I correct in assuming when each app has its own container, all except ports (and of course our python program itself) can be the same file names, as long as our primary change is to name the root folder "FLASKAPP" something different for each container? (2) What if we have different domain names pointing to each different app, how do we direct those domain names to the correct app? Does all this work on a Windows server? I assume so, because I have nginx running on my Windows 2019 server. (3) If I already have Postgres running on the same server and my ONE python app running fine using that Postgres server, do you recommend tying Postgres into the docker containers somehow? I assume my Postgres server doesn't have to be containerized? THANK YOU!
hey thanks for the tutorial. i was running into issues with my project and looked at a couple of step by step instructions and yours really stands out as the best.
I am wondering about the volumes which are presents in both services; flask and nginx. In 16:51 we see both services have a "volumes" property. Later when you removed the comments at 16:55 the 'volumes' properties were also disappeared.
If it's an error when you run "docker build", try adding "RUN apk add python3-dev build-base linux-headers pcre-dev" to the Dockerfile before "RUN pip install uwsgi"
I totally enjoyed your tutorial. Question: I run docker on a Raspberry pi and like to test remote using the pi's ip instead of the localhost can that be done?
While doing docker-compose up, I landed into an issue:- "invalid chmod value: true" for `chmod-socket=true` in app.ini file Probable fix: chmod-socket = 666 (664 can also work for www-data) uid= www-data gid= www-data, updating the above value in app.ini file fixed my issue
Are you using windows? Because you cannot install uWSGI on it (except with cygwin). What i did was skipping the pip install part of the video and only installed flask. Then in my flask docker file i changed the install dependencies to: RUN pip install uwsgi -r requirements.txt and It's working fine for me. Also, your localhost will not be where you just usually find it. You have to go to 192.168.99.100 as it is stated here: stackoverflow.com/questions/42866013/docker-toolbox-localhost-not-working
Hi , can you help me please? i have this error when i execute docker-compose up : realpath() of app.ini failed: No such file or directory [core/utils.c line 3654] thanks !
1) Update the views.py with the code: from app import app import os @app.route("/") def index(): # Use os.getenv("key") to get environment variables app_name = os.getenv("APP_NAME") if app_name: return f"Hello from {app_name} running in a Docker container behind Nginx!" return "Hello from Flask"
Excellent video!! I'm trying to add pulling code from GitHub in the compose file. Thank you so much for getting me started. I was able to build my fully working flask app using mysql as the back end in less than 2 minutes. So that is db, app and nginx in less than 2 minutes! Thank you!
Oh damn the sound his keyboard makes is really satisfying... can anybody figure out what or what kind of keyboard he uses (eg. mechanical, non-mechanical)?
Can you show us totorial how to setup WSL and VS Code because i cant set the PATHs etc I can only setup the WSL terminal but how i can use my WSL python in vscode or i need to install it on windows too
nothing to say, except mind-blowing content and teaching style. I try to find this for weeks, at last, got it. keep it up, man.

got yourself a new sub. Absolutely stunning delivery!
Excelente Julian... Muchas gracias me ayudaste bastante...
Thank You for making this video
This is such a great video.
Would you also be able to explain how a container would be able to write into a database server.
You help me well! Thank you for the guide!
Awesome!!! its so great, this one works for me ... thanks so much
Seriously good video. Thanks!
Thanks for the video. Small clarification: one does not build "containers"; one builds "images" which can be ran as containers. #languageIsKey
Exactly, containers built with
docker run or create.
Such an amazing video! just spent 3 hrs banging my head against the wall with apache and I love this process!
You could link a local volume instead so you don’t have to rebuild the container on every change, simply refresh
Hey man, thanks for the great tutorial. It helped at lot! For the next video, could you please explain how to add a Redis container to act as a queue for the requests coming into the web app?
I good improvement is to use docker volumes during development. So you don't have to build new containers every time
This is GREAT. You have explained what a developer would actually do step by step to get an app to containerization and production. I can now containerize my applications logically and simply in a very structured manner. THANK YOU! I will now watch the rest of your videos. Really appreciate your work here. Please keep sharing.

Extremely helpful! Would you be interested in making a video on implementing TLS with this kind of architecture?
Yeah, question. Say flask app is hosted in cloud somewhere. Say it's containerized with docker. How do you update app when it's live in production?

17:50 "Building an image" was actually correct. You first build an image and then create and run a container based on that image.
Great tutorial. Thank you Julian
Nice tutorial but the music is not necessary and really takes away from the entire video since you constantly hear a little "plink" all the way through.
Amazing tutorial. To the point, without making it sound too complicated.
This is what you do to get new subscribers. Wish everyone would keep this level of quality of videos. Really like your content
Hi, nice tutorials. Can you a Flask-SQLAlchemy tutorial.
Nice Video!!! I wish my ears could tune off the beeping sound.
--- no python application found, check your startup logs for errors please help
Do anyone have the problem that uwsgi error with python3.11?
i using windows to do and i cant install uwsgi, any tips?
i had the same problem, i solved that problem without copy the env folder. Just install everything globally on the container, linux can install uwsgi, but windows
Brilliant series of videos. I certainly wish I’d found them earlier! Thanks very much.
man thanks for this
Rest in Peace Julian
Is that true.
@@assaultx5677 I believe so. Forgot how I found out.
It is awful. I really thought that he is died... I checked him LinkedIn, it looks like that he is alive. This is cruel joke...
I cant for the life of me instal uwsgi on windows D: pip just wont work
How would deploy this docker container
Hi Julian, Great Tutorial. Do i really need to add the nginx part if deploying to a Synology NAS which already has nginx web server and reverse proxy set up on? Thanks Tim
I really like how you kept it basic, and EXPLAINED the basics. Well done!
Thank you so much Julian. It's extremely helpful for me to understand the overall concept. Keep rocking bro :-)

Julian come back! You had very good content!
Soon!
@@juliannash3590 Please! You're a great TH-camr.
i have a question, why i am always getting error when install uwsgi with pip in my virtual environment? is it because I use windows?
If it's an error when you run "docker build", try adding "RUN apk add python3-dev build-base linux-headers pcre-dev" to the Dockerfile before "RUN pip install uwsgi"
So what happened to Databases?
I totally enjoyed your tutorial.
Question: I run docker on a Raspberry pi and like to test remote using the pi's ip instead of the localhost can that be done?
You can use a ssh tunnel.
The video is cool. I tried to connect my docker to my local mysql server, but am getting connection refuse. Any suggestion, please
how about static files?
Where did Julian go?
Thank you Julian!
How are you using that Hyper? Is it on top of Powershell but with Unix commands? I don't quite get it.
Windows Subsystem for Linux
Thanks a lot
While doing docker-compose up, I landed into an issue:- "invalid chmod value: true" for `chmod-socket=true` in app.ini file
Probable fix:
chmod-socket = 666 (664 can also work for www-data)
uid= www-data

How did you installed the flask uWSGI? My try ended with Atribute Error: module 'os' has no attribute 'uname'. And we're using exactly the same OS.
Are you using windows? Because you cannot install uWSGI on it (except with cygwin). What i did was skipping the pip install part of the video and only installed flask. Then in my flask docker file i changed the install dependencies to: RUN pip install uwsgi -r requirements.txt and It's working fine for me.
Also, your localhost will not be where you just usually find it. You have to go to 192.168.99.100

Actually we can do updating the codes without rebuilding it. Just need to mount the dev folder with port binding in compose XML.
great intro. thks
Great tutorial. Please remove the annoying background music. It really makes it hard to hear especially at higher playback speed.
Please more vids
Thanks for the tutorial Julian, this will help a big problem I work on. Shame about the music though, very distracting. Thanks!!
Super helpful guide. But is there a way to implement hot-reloading to avoid restarting the container when making an update in the flask app
Hi , can you help me please? i have this error when i execute docker-compose up : realpath() of app.ini failed: No such file or directory [core/utils.c line 3654]
thanks !
Two changes you could do:
1) Update the views.py with the code: from app import app
import os
@app.route("/")
def index():
# Use os.getenv("key") to get environment variables
app_name = os.getenv("APP_NAME")
if app_name:
return f"Hello from {app_name} running in a Docker container behind Nginx!"
return "Hello from Flask"
2) Stop all the previous containers and restart - docker container prune
So every time I make changes I build it? Why don't you mount volume?
Thank you for the tutorial! Is it possible to run both Nginx and uWSGI in the same container?
Excellent video!! I'm trying to add pulling code from GitHub in the compose file. Thank you so much for getting me started. I was able to build my fully working flask app using mysql as the back end in less than 2 minutes. So that is db, app and nginx in less than 2 minutes! Thank you!

great video.can you make a video for debugging flask inside the container with VSCode
This was a very useful video. It got me up and running in docker and docker-compose. Thank you for sharing Julian.
Outstanding video ! Thank you! Looking forward for new videos.
Good job

I cannot get the nginx server to serve the pages. Anyone else get stuck on this? I just get the default nginx page.
I subscribed because you are criminally under-subbed. Excellent tutorial.
uWSGI does get installed on the windows machine. How did you solve that?
Can you show us totorial how to setup WSL and VS Code because i cant set the PATHs etc I can only setup the WSL terminal but how i can use my WSL python in vscode or i need to install it on windows too
@Julian, Very awesome tutorials and hope you will start continue with the new content.
