Trying to setup pm2 to restart the next.js node app on reboot of the server according to Windows: Auto start PM2 and node apps
on reboot and running pm2 ls I get :
anyone have any ideas?
C:\Users\snoruzi>pm2 ls
connect EPERM //./pipe/rpc.sock
[PM2] Spawning PM2 daemon with pm2_home=C:\Users\snoruzi\.pm2

}
The app is started by running yarn pm2
which runs the file pm2.json - which tells pm2 where the entry point of the node application is
{
"apps": [
{
"name": "centra-website",
"script": "node_modules/next/dist/bin/next",
"args": "start",
"cwd": "./",
"instances": "max",
"exec_mode": "cluster"
}
]
}
Service seems to be added fine and the pathing to executable looks correct
Try making sure that your command prompt is run as administrator. This fixed the issue for me.

I can't seem to be able to deploy a module that works on a stand alone deployment on a Kubernetes edge.
Is there anything special that needs to be done in the module?
Error thrown is as follows (thrown when trying to create hub client):
Error: connect ECONNREFUSED 127.0.0.1:35001
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1141:16) {

}
Can someone help me? Thanks!
So, I am not able to connect to MongoDB (Atlas). Feels like I may be going crazy here as logs are about as helpful as an anchor on a sinking boat. Here's what's going on. Thanks for the help.
Here's my server.js file:
'use strict';
const mongodb = require('mongodb');
const http = require('http');
const nconf = require('nconf');
let uri = 'mongodb://USERNAME:PASSWORD#cluster0-w4hci.mongodb.net/test?retryWrites=true&w=majority;';
Here's what console is saying
npm start
> test#1.0.0 start /home/XXXXXXX
> node server.js
mongodb://USERNAME:PASSWORD#cluster0-w4hci.mongodb.net/test?retryWrites=true&w=majority;
/home/XXXXXXX/node_modules/mongodb/lib/mongo_client.js:421
throw err
^
MongoError: failed to connect to server [cluster0-w4hci.mongodb.net:27017] on first connect [MongoError: getaddrinfo ENOTFOUND cluster0-w4hci.mongodb.net cluster0-w4hci.mongodb.net:27017]

Turns out my node.js driver was a different version than what I thought. Once I selected the correct version from Atlas, the URI worked and I am not connected!
I have a database setup on Mlab and I have aconnection string that does work remotely. If I run my node app on docker using my local mongo, everything works as expected, however if I change the configuration and connect to my Mlab mongo, I get the following error:

Apart from handling the error on Node side (which I'm not catching, but that's another problem), how can I connect to an external mongo server form my Docker container?
I've seen this and follow the steps described there but it didn't help me.
Any suggestions?
EDIT
This is a Node app. In my Dockerfile I have the following setting:
ENV DB_HOST=mongodb+srv://<user>:<password>#<mlab>/<db_name>?retryWrites=true
And in my Node app where I have setup the database I have this:
mongoose.connect(process.env.DB_HOST, {useNewUrlParser: true, useFindAndModify: false, useCreateIndex: true});
When I print the above env variable at run time, I get the correct string for the db (running locally everything works fine).
I don't understand why the error shows localhost. This is my first time using Docker. Do I need any additional configuration so my container can talk to an external service?
I deployed a NodeJS app to Heroku and provisioned an instance of MongoDB with MLab. Given that the password for the default database user is unclear (it never asks to set one up), I created a new user with admin privileges called mknerr. I set the MONGOLAB_URI variable like so:
heroku config:set MONGOLAB_URI=mongodb://mknerr:{password}#ds159631.mlab.com:59631/heroku_ws1jw516?authSource=heroku_ws1jw516&w=1
I tried to test the connection locally using mongo ds159631.mlab.com:59631/heroku_ws1jw516 -u mknerr -p {password} but I received the error "-bash: mongo: command not found" despite having already run npm mongodb. Rather than waste time trying to figure out where my mongo installation is, I switched to an instance of Cloud9 I know has mongo installed and ran the same command as above.
It appeared to confirm my credentials were accurate:
MongoDB shell version v3.6.5
connecting to: mongodb://ds159631.mlab.com:59631/heroku_ws1jw5l6
MongoDB server version: 3.6.6
Welcome to the MongoDB shell.
For interactive help, type "help".

However when I try to load my application, it throws a 503 error. After running heroku logs --tail I see:

Why is it failing to connect and throwing an authentication error despite my already having confirmed my credentials are accurate?
I have a Meteor Application. I am trying to deploy my application by the custom deployment procedure (on my local machine) by following this article:
https://guide.meteor.com/deployment.html#custom-deployment
But I am facing this error when I run the application via node:

Steps I performed:
First I came into the Meteor App directory and ran:
meteor build ../myapp-build --architecture os.linux.x86_64
Then I provided me the myapp.tar.gz and I extracted that.
Than I did:
- cd programs/server && npm install
- export MONGO_URL='mongodb://martini-henry:123456#192.168.100.2:9001/myappdb'
- export ROOT_URL='http://192.168.100.2:9000'
And at last when I ran:
- cd ../.. node main.js
I got that error above. What could be wrong here? Can anyone help me what I am doing wrong here?
