cloud-init user-data script is not working on centos 7

[bobbybhaskar]

Hello everyone,

In cloud-init I took one of the centos VM, while I am creating the VM there is an option called "custom data" in that given one of the sample scripts for testing, I attach the script.

just follow this link "

([(https://docs.microsoft.com/en-us/azure/virtual-machines/linux/tutorial-automate-vm-deployment)])

OS:

[root@centos-7-cloud-init cloud.cfg.d]# cloud-init --version /bin/cloud-init 19.4

script:

cloud-config

• owner: azureuser:azureuser path: /home/azureuser/myapp/index.js content: | var express = require('express') var app = express() var os = require('os'); app.get('/', function (req, res) { res.send('Hello World from host ' + os.hostname() + '!') }) app.listen(3000, function () { console.log('Hello world app listening on port 3000!') }) runcmd:
• service nginx restart
• cd "/home/azureuser/myapp"
• npm init
• npm install express -y
• nodejs index.js

After deployment of centos VM the "user-data script" is not working, these are logs

I have doubt that when I tested on the ubuntu machine is working fine, but I tried a number of times on centos vms still it is not working, is script issue or centos os is not compatible for cloud-init?

Here I attached cloud-init logs cloud-init.log

Thanks,

Bobby.

Hi @bobbybhaskar ,

That script in the quickstart is intended for an UbuntuLTS image.

Azure Supports cloud-init for a number of CentOs images. See the list here to ensure your using the correct version for your script. This doc here has good examples for a Centos image.
