I&#39;ve used both recently (2017-2018), and they are both super stable with Celery 4.  So your choice can be based on the details of your hosting setup.

* If you must use Celery version 2 or version 3, go with RabbitMQ. Otherwise...
* If you are using Redis for any other reason, go with Redis
* If you are hosting at AWS, go with Redis so that you can use a managed Redis as service
* If you hate complicated installs, go with Redis
* If you already have RabbitMQ installed, stay with RabbitMQ

In the past, I would have recommended RabbitMQ because it was more stable and easier to setup with Celery than Redis, but I don&#39;t believe that&#39;s true any more.

&lt;hr&gt;
**Update 2019**

AWS now has a managed service that is equivalent to RabbitMQ called Amazon MQ, which could reduce the headache of running this as a service in production.  Please comment below if you have any experience with this and celery.

I have the following docker images.

    $ docker images
    REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
    hello-world         latest              48b5124b2768        2 months ago        1.84 kB
    docker/whalesay     latest              6b362a9f73eb        22 months ago       247 MB

Is there a way I can see the Dockerfile of each docker image on my local system?

The answer at https://stackoverflow.com/q/37058364/1175080 does not help me because it does not exactly show the Dockerfile but the commands run to create the image. I want the Dockerfile itself.

How can I see Dockerfile for each docker image?

I have an ASP.NET Web Api solution which doesn&#39;t contain a Startup.cs class. I presume this is because the solution wasn&#39;t created as an MVC solution.

All the code for the startup is defined in the Global.asax.cs file as you can see below

    public class Global : HttpApplication
    {
        void Application_Start(object sender, EventArgs e)
        {
            // Code that runs on application startup
            AreaRegistration.RegisterAllAreas();
            GlobalConfiguration.Configure(WebApiConfig.Register);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
        }
    }

However, now I want to have support for OAuth and all the documentation that I&#39;ve found is based on a Startup.cs with the following class

    public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            ConfigureAuth(app);
        }
    }

Is it possible to just add this new class in my solution and the solution will continue working?

Will this have any conflicts with the Global.asax.cs class?

**EDIT**: After I added the Startup.cs class, I can&#39;t hit the break point I added into it... 

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using Microsoft.Owin;
    using Owin;
    
    [assembly: OwinStartup(typeof(MyGame.Startup))]
    
    namespace MyGame
    {
        public partial class Startup
        {
            public void Configuration(IAppBuilder app)
            {
                ConfigureAuth(app);
            }
        }
    }

Any idea what&#39;s going on?

My rough understanding is that Redis is better if you need the in-memory key-value store feature, however I am not sure how that has anything to do with distributing tasks?

Does that mean we should use Redis as a message broker IF we are already using it for something else?

Celery: When should you choose Redis as a message broker over RabbitMQ?

Actually, what I do is: 

 - Delete the migration file.
 - Delete the row from the table of django_migrations on the database.
 - Delete the changes applied by the migration that I want to delete or unapplied.

I want to know if there&#39;s another way to do this.

Is there a way to undo a migration on Django and uncheck it from the list of showmigrations?

I am using a **LocalExecutor** and my dag has **3 tasks** where task(C) is dependant on task(A). Task(B) and task(A) can run in parallel something like below

A--&gt;C

B

**So task(A) has failed** and but **task(B) ran fine**. Task(C) is yet to run as task(A) has failed.

My question is **how do i re run Task(A) alone so Task(C) runs** once Task(A) completes and Airflow UI marks them as success.

I am trying to make a very simple `Subquery` that uses `OuterRef` (not for practical purposes, but just to get it working), but I keep running into the same error.

`posts/models.py` code


    from django.db import models

    class Tag(models.Model):
        name = models.CharField(max_length=120)
        def __str__(self):
            return self.name

    class Post(models.Model):
        title = models.CharField(max_length=120)
        tags = models.ManyToManyField(Tag)
        def __str__(self):
            return self.title

`manage.py shell` code

    &gt;&gt;&gt; from django.db.models import OuterRef, Subquery
    &gt;&gt;&gt; from posts.models import Tag, Post
    &gt;&gt;&gt; tag1 = Tag.objects.create(name=&#39;tag1&#39;)
    &gt;&gt;&gt; post1 = Post.objects.create(title=&#39;post1&#39;)
    &gt;&gt;&gt; post1.tags.add(tag1)
    &gt;&gt;&gt; Tag.objects.filter(post=post1.pk)
    &lt;QuerySet [&lt;Tag: tag1&gt;]&gt;
    &gt;&gt;&gt; tags_list = Tag.objects.filter(post=OuterRef(&#39;pk&#39;))
    &gt;&gt;&gt; Post.objects.annotate(count=Subquery(tags_list.count()))

The last two lines should give me number of tags for each Post object. And here I keep getting the same error:

    ValueError: This queryset contains a reference to an outer query and may only be used in a subquery.

I&#39;m using the regular `redis` package in order to connect my Python code to my Redis server.

As part of my code I check if a string object is existed in my Redis server keys.

    string = &#39;abcde&#39;
    if string in redis.keys():
      do something..

For some reasons, redis.keys() returns a list with bytes objects, such as `[b&#39;abcde&#39;]`, while my string is, of course, a `str` object.

I already tried to set `charset`, `encoding` and `decode_responses` in my redis generator, but it did not help.

My goal is to insert the data as string ahead, and not iterate over the keys list and change each element to str() while checking it.

Thanks ahead

This was probably asked already, but so far I can&#39;t find any detailed explanation at all, and the existing documentation seems as if it was written for some kind on psychic who supposed to know everything.

As per this [manual][1], I added the container

    docker run -d --hostname my-rabbit --name some-rabbit rabbitmq:latest

Then I checked it to receive the container ip

    docker inspect some-rabbit
Checked ports with

    docker ps

And tried to connect in the browser with this formula

    https://{container-ip}:{port}

It did&#39;t work.

Am I&#39;m doing something wrong, or maybe I am supposed to add something additional, like a container for apache or other stuff?

**EDIT**

As I understand, after creating some-rabbit container, now I need to run Dockerfile to create image? (This whole thing is confusing to me). How am I supposed to do that? I mean, I saw command `docker build -f /path/to/a/Dockerfile` but if for example I placed the Dockerfile in second path `D:\Docker\rabbitmq`, how I supposed to get there? (the path doesn&#39;t seems to be recognized)

How to open rabbitmq in browser using docker container?

Given [ReadOnlyMemory&lt;T&gt; Struct][1] I want to convert the stream into a string

I have the following code:

    var body = ea.Body; //ea.Body is of Type ReadOnlyMemory&lt;byte&gt;
    var message = Encoding.UTF8.GetString(body);
    Console.WriteLine(&quot; [x] Received {0}&quot;, message);

And it gives the following error. I am using the latest C# with .NET CORE 3.1

[![enter image description here][2]][2]

Which is funny because I am literally copy pasting the Hello World example [of a major product called RabbitMQ][3] and it doesn&#39;t compile.

C# Convert ReadOnlyMemory&lt;byte&gt; to byte[]

I have RabbitMQ and Celery running locally on my Mac (OS/X 10.13.4), the following code works locally when I run add.delay(x,y):

    #!/usr/bin/env python
    from celery import Celery
    from celery.utils.log import get_task_logger

    logger = get_task_logger(__name__)

    app = Celery(&#39;tasks&#39;, \
            broker=&#39;pyamqp://appuser:xx@c2/appvhost&#39;, \
            backend=&#39;db+mysql://appuser:xx@c2/pigpen&#39;)

    @app.task(bind=True)
    def dump_context(self, x, y):
        print(&#39;Executing task id {0.id}, args: {0.args!r} kwargs {0.kwargs!r}&#39;.format(self.request))

    @app.task
    def add(x, y):
        logger.info(&#39;Adding {0} + {1}&#39;.format(x, y))
        return x + y

However when I try to run the Celery worker on an ODROID-C2 running Kali 2018.2 (w. current updates, I get the following error when running `celery -A tasks worker --loglevel=info`:

From the Kali ODROID I am able to connect to the RabbitMQ instance on the host named c2 using a Python Pika script and mysql from that device works to the c2 machine as well. I have found similar errors, none of those solutions have worked for me.

Celery version installed on the ODROID-C2 via pip is:

    celery --version
    4.1.0 (latentcall)


Celery AttributeError: async error

I was wondering what the correct approach to deploying a containerized Django app using gunicorn &amp; celery was. 

Specifically, each of these processes has a built-in way of scaling vertically, using `workers` for gunicorn and `concurrency` for celery. And then there is the Kubernetes approach to scaling using `replicas`

There is also this notion of setting workers equal to some function of the CPUs. Gunicorn recommends 
&gt;2-4 workers per core

However, I am confused what this translates to on K8s where CPU is a divisible shared resource - unless I use resoureceQuotas.

I want to understand what the Best Practice is. There are three options I can think of:

- Have single workers for gunicorn and a concurrency of 1 for celery, and scale them using the replicas? (horizontal scaling)
- Have gunicorn &amp; celery run in a single replica deployment with internal scaling (vertical scaling). This would mean setting fairly high values of workers &amp; concurrency respectively. 
- A mixed approach between 1 and 2, where we run gunicorn and celery with a small value for workers &amp; concurrency, (say 2), and then use K8s Deployment replicas to scale horizontally.

There are some questions on SO around this, but none offer an in-depth/thoughtful answer. Would appreciate if someone can share their experience.

Note: We use the default worker_class `sync` for Gunicorn

Docker/Kubernetes + Gunicorn/Celery - Multiple Workers vs Replicas?

What is the meaning of `bind=True` in below **celery** code? When to use it and when not?

```
@app.task(bind=True)
def send_twitter_status(self, oauth, tweet):
    try:
        twitter = Twitter(oauth)
        twitter.update_status(tweet)
    except (Twitter.FailWhaleError, Twitter.LoginError) as exc:
        raise self.retry(exc=exc)
```
