Deploy your Flask app on Google Cloud Platform 

Thanks! Please checkout my blog I would love feedback!

@@lesliewubbel9157 I liked your website. A recommendation would be to get the current user’s device theme and set the background color based on that

Glad it helped!

No problem

No problem, I have been there done that before with the same issue its the concept is not explained in depth its important. On deployment is always issue too

Thank!

Thanks man

Thanks man I appreciate the support

Thanks

That is my wife lmao

Option 1. You have to ssh into the cloud run service container there should be some information in the google cloud dashboard heres a link I hope that helps. Then you edit the .env file but would have to restart the application for it to pick the .env file changes cloud.google.com/compute/docs/ssh-in-browser Option 2. is redeployment which is the more realistic thing DevOps does when we have to connect entire other software to your platform or new databases you will need to redeploy and do the whole build process again anyways. This is the unfortunate reality of the DevOps, they do build custom tools you build off the self to manage and automate .env files but this really out of scope for this video locally you can just edit the .env file and see the changes update locally to test stuff out first however I know you are talking about the deployment specifically here

Sure np, in terminal that is default behavior and in vscode I use github copilot. Als the code is from the blog post linked in the description

Yes it's from google's docs this a default dockerfile used to make deployments its in the blog post the hyperlink should be there if its not just tell me and I will update it

Could dump the logs here or in a paste bin? Others are getting thus error I havnt experience it but it would be a great help

It is indeed, I answered my own question so it's all good haha

yes!

Thanks!

Let me get back to you tomorrow

@@lesliewubbel9157 thank you for the update

​@@martinmalic5411 Hi martin sorry for that late response I have been super busy lately I am getting my MBA right now its best to just set up a zoom call? lesliemwubbel.com/11-consulting/ 1. Best guess without seeing your code is that the template files were not copied from your local machine to the cloud instance when you deploy I would double check the the dockerignore file to see if html files are being ignore on deployment SSH into the Cloud instance to 2. Then I would check your endpoint @app.route('/upload', methods=['POST']) if your @app.route is not set to @app.route('/' ) that is your homepage on URL So I need to see code? is the template render function being called on the endpoint? Try to use paste bin? to share code with me Images of folder structure helps too Lot of different things could trigger this? - Check Server Logs - Verify Dependencies - File Permissions - Web Server Configuration - Application Errors - Network Configuration -Resource Limits

@@lesliewubbel9157 hi Leslie thanks for getting back. I've managed to get my app working by uploading it to pythonanywhere instead!

@@lesliewubbel9157 Leslie, many thanks for your response and congrats on your MBA. At the moment I have managed to host the web-app on pythonanywhere which seems to do the job just fine for my needs. Let's not waste your time at the moment, I appreciate you taking the time however. Perhaps in the future. Martin (I think I responded already, but I don't see it so here's another try)

Sure I can make a video on that

@@lesliewubbel9157 thank you so much

Truthfully I don't know, I have not been in that situation, but I would look into microservices, docker, and proxy engine nginx.org/en/ to handle high server loads it should work but there are ways to load balance. I would google load balancing

Can you double check the docker file? the last line should be CMD exec gunicorn --bind :$PORT --workers 1 --threads 8 --timeout 0 app:app also check check the yaml file was that create it should match runtime: python39 entrypoint: gunicorn -b :$PORT app:app if not I will have go through it again and make sure its all correct on my tutorial

@@lesliewubbel9157 Actually, I think I got it to work already. For some reason my docker does not recognize the environment variable (PORT) and also some of my api key (being used in the backend file that I had). So I went ahead and manually add the key (secret key) on the google cloud directly, and it works. Thanks for such a swift response. Appreciated!

@andrewchou1720 was it .environment variable I think it's missing from my blog post if that is true

I got the same issue. "...The user-provided container failed to start and listen on the port defined provided by the PORT=8080 environment variable." I have confirm: app.yaml -> entrypoint: gunicorn -b :$PORT app:app Dockerfile -> CMD exec gunicorn --bind :$PORT --workers 1 --threads 8 --timeout 0 app:app I tried changing .env to PORT=5000, but it still saying, PORT=8080 on gcloud deploy...

@PaulThach1 did you get to work? I can come Back and take look

It could be a number of reasons you could check the logs first as a clue

It shouldn't be too different just managing DNS and domain name becomes a waste of time that is why I perfer using Netlify or vercel

What is your frontend?

just react front end , wanted to learn more on how to do both front end and backend into gcp

@@jz319 I think I can figure it out for react front-end, how about a video?

That willl be great !! THANK YOU !!

Yes this happens sometimes Restarted the VScode?

Try plug in called Google Cloud Code see if that helps

did you resolve it?

@@lesliewubbel9157 no but I found a solution other than Google cloud. If I come to need Google cloud again I Will certainly do that. Thanks a lot

@@lesliewubbel9157 I had this same issue and restarting VS Code fixed the issue

could you print out your requirements.txt for me here?

@@lesliewubbel9157 i did reply but that comment is disapearing idk how!!

@vaishnavikulkarni663 you have to refresh youtube I think youtube algo is checking comments I had the same issue

Huh sorry I don't understand. Do you want a tutorial purely on flask? Correct? Then a in depth tutorial on deployment logic like ports? Dockerfile?

Yea I think he means a flask tutorial for building real life apps. I also feel a flask playlist would be really helpful, most flask tutorial on YT are old, a modern series of flask tutorial vids in 2024 would be nice. Then ofcourse, how to deploy the flask app over the cloud so that end users are able to use them.@@lesliewubbel9157

Check the logs? In Google cloud dashboard?

What does the network tab say on the browser?
