  1. I am getting this error "PermissionError: [Errno 13] Permission denied: '/app/vol'". Can anyone help me?

  2. Gonna be first one disliked, but this video is waste if time. Instead of focusing on actual deployment, which you would expect googling the header topic, you get 'yet another' video on how to compose a set of containers with Django, DB and NGINX.
    Deployment? Oh, yes — SSH to your host, pull it all from there and run rebuild command. Yes, from the host as well.

    Where's actual deployment? Where are Github's CD jobs? Where's anything that would make this video actually match its title?

  3. thank You very much for the class but I ran into a problem when running docker-compose build and here is response i got

    Error while fetching server API version: (2, 'CreateFile', 'The system cannot find the file specified.')

    [9676] Failed to execute script docker-compose

  4. Great tutorial! However – anyone got any pointers on how to deploy this container set-up as https with Lets Encrypt?

  5. Thanks for taking out time to create this tutorial. This video sooo good that I had to purchase the advanced course.

  6. Hi, very nice tutorial indeed. I have question regarding applying SSL Certificate on Nginx and expose to port 443. Do you have any working example?

  7. Why do you recommend using alpine for python? I had so much trouble getting it set up and running correctly with the latest versions of Django and python (4.0.2 and 3.10.2, respectively) that I decided to build without it and it went so much more smoothly, albeit at a larger total size (1.3gb total)

  8. could you help to make an example how to add SSL certs to nginx django uwsgi deploy with docker. thankyou so much

  9. Hi Mark! Please let me know how to do port mapping in order to scale up this website. You just worked on admin url, anything other url doesn’t work. It say thay “Not found”.

  10. db_1 | 2022-01-20 10:09:47.641 UTC [67] DETAIL: Password does not match for user "approotuser".
    db_1 | Connection matched pg_hba.conf line 99: "host all all all md5"
    db_1 | 2022-01-20 10:09:48.645 UTC [68] FATAL: password authentication failed for user "approotuser"
    db_1 | 2022-01-20 10:09:48.645 UTC [68] DETAIL: Password does not match for user "

  11. Hello! You didn’t tell how to resolve the issue of Not found, that happened almost in the end of video. please let me know that how to do port mapping in docker-compose-deploy.yml, only admin endpoint is working. i want to extend this website by adding more different thing. please reply and help me with it

  12. Great video Mark, keep up the good work! I like the way you slowly explain what you do with no extra unnecessary "decorative" remarks. Hope to have a pint of beer with you sometime in London mate!

  13. For some reason, the wait_for_db command is stuck in a loop even after postgres is available

  14. I am so thankful for your video Mark. You are an excellent, EXCELLENT teacher. One of the best tutorials for CS on Youtube for any subject! Keep up the wonderful work and I will be praying for your channel to grow even more!

  15. Hey Mark, in my opinion one of the best tutorials on youtube. Thank u very much for your detailed explaination. This helped me a lot for our university project. kind greetings from germany

  16. Can you tell about how to handle the "502 Bad Gateway nginx" error. server runs on a digital ocean droplet. I tried to access the server via droplets public ip

  17. Thank you very much for this tutorial Mark. I suffered for more than 48 hours trying to solve the permission denied error. I had to add the line “`chown -R user:user /app“` to my Dockerfile to get rid of the error and finally fully deploy my app. I am trying to integrate SSL certificate i will report back on how it goes

  18. I had to set the owner of the /data to the UUID of the docker user during debugging manually to proceed. Did I skip a crucial step?

  19. Thanks for the excellent tutorial Mark. successfully tested the deployment on the production server locally but, have some problem in the development, particularly in the " MEDIA_ROOT='/vol/static/media' ", it gives me Permission denied error and was not mounted on the "/data/web", but when using " MEDIA_ROOT='vol/static/media/' ", there is no error and can saved the media in "app/app/vol/static/media" and was not mounted in "/data/web/". anyway, the production deployment was great locally, haven't tested it yet in the actual production server, thanks Mark. keep it up.

  20. This is exactly what I have been looking for. I took your "Rest API" course on Udemy and learned a lot. Thanks again.

  21. Thanks for this wonderful tutorial. I took your course on Django API using docker Udemy, lovely course, but it could use an update. Thanks once again

  22. Just something you didn't touch in this video. if I wanted to map the database info in case i had any problem with the container and all the info got lost I would add:
    volumes:

    – ./data/db:/var/lib/postgresql/data

  23. Yo Mark! I purchased your advanced Django course on Udemy a couple of years ago and it's the best damn course on the subject. Perhaps the only thing missing was how to deploy the project to AWS using Docker containers, so thanks for this video! Keep up the good work, my dude.
