Thanks, was waiting for this video. I attended the live, but still wanted to have this reference in case I forgot anything.

So I'm going through this with my own project and I'm getting the following error when trying to do my first "migrate"
django.db.utils.OperationalError: connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory
Is the server running locally and accepting connections on that socket?

[@yooujiin]

At the end, I get this error when creating superuser "[15/May/2023:19:49:40] Superuser created successfully.

si was was running a django app using rds, ec2, load balancers etc.. but it was just too expensive... How is deploying to lightsail cost? wat monthly cost are we looking at?

[@LondonAppDeveloper]

You can get all the pricing here: aws.amazon.com/lightsail/pricing/
Too be honest, the price might be similar to using EC2 / Load Balancer / RDS directly. The benefit of lightsail is that the pricing is more predictable.
If you want something really cheap then best bet is to run everything on a single VPS (database, app, etc...). For this, my personal preference is katapult.io. You could also check out fly.io/docs/about/pricing/

[@rishabhdugar2]

I am facing an issue, it states:
exec /scripts/run.sh: no such file or directory
Please help me understand the issue and the way to resolve it

[@LondonAppDeveloper]

Is the run.sh file spelled correctly and in the right location?

[@alan-overthenet]

Thanks very much for this. Sorry I missed it live.

[@LondonAppDeveloper]

No worries. We're doing another on March 15th. if you can come.

[@태기_개인]

You are amazing!!

[@LondonAppDeveloper]

Thank you! So are you.

[@adammisiak4082]

Thanks for the video!
What is the average cost of this kind of setup?

[@LondonAppDeveloper]

I think roughly $30 a month.

[@of7104]

Why do I keep getting this error;
[26/Jul/2024:21:50:59] django.core.exceptions.DisallowedHost: Invalid HTTP_HOST header: '172.26.31.219'. You may need to add '172.26.31.219' to ALLOWED_HOSTS.

[@of7104]

To clarify the request are coming in every 5 seconds, so I'm wondering if some sort of internal health check?

[@of7104]

In case anyone ends up wondering - solved this with; ALLOWED_HOSTS = []
ALLOWED_HOSTS.extend(
filter(None, os.environ.get('ALLOWED_HOSTS', '').split(','))
)
ALLOWED_HOSTS.append(gethostbyname(gethostname())). Do please let me know if this isn't best practice

[@LondonAppDeveloper]

As some have pointed out, to resolve this you’ll need to add the IP address of the running host to the ALLOWED_HOSTS in settings.py.
There's an example in our API deployment course: github.com/LondonAppDeveloper/devops-recipe-app-api/blob/main/app/app/settings.py#L38
Essentially:
```
from socket import gethostname, gethostbyname
…
ALLOWED_HOSTS = []
ALLOWED_HOSTS.append(gethostbyname(gethostname()))
```

@@LondonAppDeveloper that’s great thank you. First website now deployed and working well - thanks for the video!
