502 Bad Gateway Django - django

I have a simple application that allows you to upload images onto the server, and it is set up on my production server which consist of django + uwsgi + ngnix .
I have a problem when trying to upload an image. I get the following error:
error
502 Bad Gateway
nginx/1.2.1
function:
def upload(request):
form = ImageForm()
context = {'form':form,}
context.update(csrf(request))
if request.POST:
form = ImageForm(request.POST, request.FILES)
if form_is.valid():
image = request.FILES.get('image')
CarPhoto.objects.create(user=request.user,cars=1,description='dwq',image=image)
return HttpResponseRedirect(reverse('transformer:kevin'))
return render_to_response('image.html',context,context_instance=RequestContext(request))

It sounds like your uWSGI instance has died or is failing in such a way that it does not know how to answer.
Start by watching the nginx logs in addition to the uWSGI logs and see how far it gets.
Perhaps the file you are uploading is so large it is choking some front streaming portion.
Edit your post to indicate the output of the two log files and we will see.


if third party app included in your project then it should be installed on your server also like south is third party app.
Consider south is included in your settings.py file then south should be installed on your server also.
If that module consider south here, is already installed on server then try to upgrade it. Because it is possible that you are using upgraded version of module on local machine and older version is installed in the server.

ELB processes are not healthy on all instances

I am trying to deploy a Python Dash app to EC2 and have been trying to figure out this error for the past two days (ELB processes are not healthy on all instances;
ELB health is failing or not available for all instances). I'm able to log into the app using the amazon url but it seems like it is not calling the api properly. I suspect the instance is not connected to the internet.
I have tried spinning up new instances multiple times but am still getting the same result.

intermittent 502 Bad Gateway nginx/1.18.0 (Ubuntu)

My django app has ben running for about 3 months now.
I intermittently get a 502 Bad Gateway error message on any page,
I will even get this error the Django admin page, so I don't think its my code. Most of the time the page loads fine, or if I just reload it will load.
can someone help me understand where I'm making a mistake

502 Bad Gateway nginx/1.20.0 Error when Deploying Django app using AWS Elastic Beanstalk

I was following closely following AWS's documentation on how to deploy Django apps using Elastic Beanstalk until I received a 502 Bad Gateway nginx/1.20.0 Error when opening my app. From there, I followed a couple of solutions offered by users that suffered similar problems. Specifically, I added a Procfile and went about editing how my django.config file was set up. However, the error still remains and I would like some guidance on how to tackle this problem. Below are the relevant logs and files:

From the looks of it, the deployment seems successful. However, based on a handful of other posts like this, the nginx logs seem to show there may have been something wrong with getting gunicorn to work as the web server gateway interface. Any advice on how to solve this problem?

my deployment is still not good for production as I still have to provision manually from aws console the postgres database and change the SG inbound rules for the database.
so far this is what I came up with.
this is my diango.config file inside .ebextensions/ :
option_settings:
aws:elasticbeanstalk:application:environment:
DJANGO_SETTINGS_MODULE: "projectname.settings"
PYTHONPATH: "/var/app/current:$PYTHONPATH"
AWS_STORAGE_BUCKET_NAME: "nameofbucket"
AWS_S3_REGION_NAME: "yourregion"
RDS_USERNAME: "dbusername"
RDS_PASSWORD: "dbpassword"
RDS_PORT: 5432
aws:elasticbeanstalk:container:python:
WSGIPath: "projectname.wsgi:application"
NumProcesses: 3
NumThreads: 20
aws:elasticbeanstalk:environment:process:default:
HealthCheckPath: "/about"
MatcherHTTPCode: "200-499"
aws:elasticbeanstalk:environment:proxy:staticfiles:
/static: static
/media: media
container_commands:
01_makemigrations:
command: "source /var/app/venv/*/bin/activate && python3 manage.py makemigrations --noinput"
leader_only: true
02_migrate:
command: "source /var/app/venv/*/bin/activate && python3 manage.py migrate --noinput"
leader_only: true
03_createsu:
command: "source /var/app/venv/*/bin/activate && python3 manage.py createsu"
04_collectstatic:
command: "source /var/app/venv/*/bin/activate && python3 manage.py collectstatic --noinput"
leader_only: true
this will create an enviroment that has not a database, I then provision from the console a postgres database.
I then run from terminal a script to set enviromental variable inside elastic beanstalk:
#!/bin/bash
eb setenv \
AWS_ACCESS_KEY_ID='' \
AWS_SECRET_ACCESS_KEY='' \
RDS_DB_NAME='' \
RDS_HOSTNAME=''
inside my setting.py file I pass something like this:
from decouple import config
DEFAULT_AUTO_FIELD = "django.db.models.BigAutoField"
STATIC_URL = "/static/"
STATIC_ROOT = BASE_DIR / "static"
MEDIA_URL = "/media/"
MEDIA_ROOT = BASE_DIR / "media"
try:
from .local_settings import *
AWS_ACCESS_KEY_ID = config("AWS_ACCESS_KEY_ID")
AWS_SECRET_ACCESS_KEY = config("AWS_SECRET_ACCESS_KEY")
AWS_STORAGE_BUCKET_NAME = config("AWS_STORAGE_BUCKET_NAME")
AWS_S3_REGION_NAME = config("AWS_S3_REGION_NAME")
except ImportError:
print("no local file found")
## Django storages - use this for production
STATICFILES_STORAGE = "storages.backends.s3boto3.S3Boto3Storage"
DEFAULT_FILE_STORAGE = "storages.backends.s3boto3.S3Boto3Storage"
print("no local file found you are in production")
# Database
# https://docs.djangoproject.com/en/3.2/ref/settings/#databases
DATABASES = {
"default": {
"ENGINE": "django.db.backends.postgresql_psycopg2",
"NAME": os.environ["RDS_DB_NAME"],
"USER": os.environ["RDS_USERNAME"],
"PASSWORD": os.environ["RDS_PASSWORD"],
"HOST": os.environ["RDS_HOSTNAME"],
"PORT": os.environ["RDS_PORT"],
}
}
AWS_ACCESS_KEY_ID = config("AWS_ACCESS_KEY_ID")
AWS_SECRET_ACCESS_KEY = config("AWS_SECRET_ACCESS_KEY")
AWS_STORAGE_BUCKET_NAME = config("AWS_STORAGE_BUCKET_NAME")
AWS_S3_REGION_NAME = config("AWS_S3_REGION_NAME")
this makes my project up and running on Elastic Beanstalk. as I said it is still not fully automatic as the part where I provision the database inside the config file does not work. Hope it is useful.

It seems like port 80 is important for AWS Elastic Beanstalk running a Docker environment with nginx. Make sure you EXPOSE 80 and EXPOSE 8000 in your Dockerfile. I was using docker-compose too, so I had to add ports: - 80:8000 to my docker-compose.yml.

AWS elasticbeanstalk with django isn't Working

]
I've never used an AWS Beanstalk before, and I get this error, and when I actually get to the address, the "502 badgateway" error is executed how can I solve this problem?(I'm using django)
Edit
I also downloaded the log and those are the errors

Why is my Springboot deployment to EBS not working?

I am trying to deploy a small SpringBoot application to EBS. I think I have done everything right, including setting up an RDS database, but the deployment fails and I get an error with health degraded as : Following services are not running: application-web-1.
My variables are setup as follows
GRADLE_HOME
/usr/local/gradle
JAVA_HOME
/usr/lib/jvm/java
M2
/usr/local/apache-maven/bin
M2_HOME
/usr/local/apache-maven
SERVER_PORT
5000
SPRING_DATASOURCE_PASSWORD
***
SPRING_DATASOURCE_URL
jdbc:mysql://***.us-east-2.rds.amazonaws.com/ebdb
SPRING_DATASOURCE_USERNAME
***
SPRING_JPA_DATABASE_PLATFORM
org.hibernate.dialect.MySQL5Dialect
SPRING_JPA_HIBERNATE_DDL_AUTO
***
SPRING_PROFILES_ACTIVE

Any advice on how to debug?

Hey I'm not sure if this will work for you, but this is how I solved the
Following services are not running: application-web-1.
issue. I ssh'd onto my elastic beanstalk instance and cd'd to the /var/log directory. I noticed that there was a
web-1.error.log
log showing. I vi'd that log file and there was the exception that was causing the deployment to fail. A txt file that was nested inside a folder within my resources folder was not visible and the following exception was being thrown.
Caused by: java.io.FileNotFoundException: URL [jar:file:/var/app/current/application.jar!/BOOT-INF/classes!/vegetables/vegetables.txt] cannot be resolved to absolute file path because it does not reside in the file system: jar:file:/var/app/current/application.jar!/BOOT-INF/classes!/vegetables/vegetables.txt
This occurred because I was using PathMatchingResourcePatternResolver to get the resources, then traversing the resources by filename, and directly trying to access the file by using resource.getFile(). Instead of getting the data by the file. I used
byte[] dataArr = FileCopyUtils.copyToByteArray(resource.getInputStream());
and that allowed me to use the data in the byte array the same way I used it by accessing the file directly. I hope this helps.
