I want to scale my application using cluster package of meteor . I have used these two commands in the terminal.
CLUSTER_DISCOVERY_URL=mongodb://mongo-url CLUSTER_SERVICE=web
CLUSTER_ENDPOINT_URL=http://ipaddresss:port meteor
The CLUSTER_DISCOVERY_URL is the URL to a MongoDB database. The cluster package uses the MongoDB database to communicate between the Meteor applications. This database can be the Meteor application database (where all your other collections are stored) or a different one.
The CLUSTER_SERVICE variables stores a name for your application which is used internally by the package.
The CLUSTER_ENDPOINT_URL is the URL to your application.
After running these commands my application has not started on my local machine and it does not show any error in the console.
How can I solve this?

According to the Next.js docs, using Create Next App has the benefit of Offline Support:
Create Next App will automatically detect if you're offline and bootstrap your project using your local package cache.
If I turn off wifi and try npx create-next-app or pnpm create next-app, I'll get errors even if I've previously ran the commands while connected to wifi (thus presumably creating a local package cache).
How is this supposed to be used?
I have an R script that I need to run once every week. I need it to be done using Azure. One option is to use Azure Data Factory and set up a pipline what will run this R script on a VM (Windows).
The problem I'm facing is that I will have to update every now and then both the R script and the R packages the R script is using.
When setting up this pipeline I will have to generalize the VM (correct me if I'm wrong) and doing so I can no longer log into this VM. And if I can't log into this VM I cannot update the R packages.
What options do I have here?
There is an alternate solution where you can use Azure Batch Service and Azure Data Factory to execute R scripts in your pipeline.
For more information, you can refer this blog: How to execute R Scripts using Azure Batch Services and Azure Data Factory? | by Aditya Kaushal | Medium
Alternatively, to run R scripts in your VM, you can use below options:
Custom Script Extension
Run Command
Hybrid Runbook Worker
Serial console

When developing with Meteor locally, one execute meteor reset locally to refresh the database.
Can one run this command on a production level app deployed on Bluemix without digging into the Mongo console?
The meteor reset command actually deletes the local mongo database files in .meteor/local. Since the database isn't stored in the application container when running in Cloud Foundry, there isn't an equivalent operation as a one liner.
Seems like your only option is to retrieve the connection credentials from your application cf env appname and then stop the application, connect with the mongo command line, and use one of the methods described in this answer to clean your data out.
I develop Meteor application on my local computer, and deploy it to meteor.com. I want to have an opportunity to use remote production MongoDB database for local development.
So, I get url to my DB with meteor mongo --url myapp.meteor.com, then I add it to my MONGO_URL environment variable:
export MONGO_URL=mongodb://client-5345a08c:5f63edff-8cec-a818-7f35-c05021bb6d91#production-db-d1.meteor.io:27017/34377_ru
The inconvinience is that this url is invalid in one minute, so I need to generate another one and modify my MONGO_URL every time I want to start my application. I suspect some permanent url to my MongoDB is out there. I ran meteor mongo myapp.meteor.com and noticed greeting:
MongoDB shell version: 2.4.9
connecting to: production-db-d1.meteor.io:27017/34377_ru
I tried to use this url:
export MONGO_URL=mongodb://production-db-d1.meteor.io:27017/34377_ru
and even
export MONGO_URL=mongodb://myneteorcomusername:mymeteorcompassproduction-db-d1.meteor.io:27017/34377_ru
but I had no luck.
Are there ways to simplify my workflow and make meteor use my remote database by default?
I guess for scaling purposes, there is no dedicated mongo ever for each subdomain. I could be wrong so better ask this question over at the Meteor Talk Google group.
I want to use Meteor packages (like minimongo) outside the main Meteor app. Furthermore, I would like to connect to the MongoDB database of running Meteor app. So that I can have a background worker and similar things which should read/write to the app database. I would like to use minimongo to be really compatible with Meteor (like having same IDs). And I would like to be able to connect to app database also in development.
