Setting environment variable in virtual machine scale set (Linux VM)

Question

_{Wednesday, June 5, 2019 9:23 AM}

Hello all,

I am trying to set environment variables in all scale-set instances. To do this, I added a custom_script_for_linux_extension. The script contained the following information:

#!/bin/bash

export user=test
export password=test123
export secrettoken=67890-9877ghkl

exit

The script deployed successfully but i could not see environment variables. The instances have linux vm (ubuntu).

I even tried the following information but unfortunately the deployment failed saying it cannot access .profile or .bashrc

#!/bin/bash

if [ -z "$user" ]
then
    echo "Setting user information"
    echo "export user=test">>~/.profile
    echo "export password=test123">>~/.profile
    echo "export secrettoken=67890-9877ghkl">>~/.profile
    echo "export user=test">>~/.bashrc
    echo "export password=test123">>~/.bashrc
    echo "export secrettoken=67890-9877ghkl">>~/.bashrc
    . ~/.bashrc
    . ~/.profile

else
      echo "user information is already present"
fi
exit

I am trying to get environment variables in my java problem. How do i set environment variables in azure vmss so that all the current and autoscaled instances have environment variables?

I would suggest looking into using a Custom image instead of Custom Script Extension to set the variables. 

/en-us/azure/virtual-machine-scale-sets/tutorial-use-custom-image-powershell

This will allow any new instances that get added to your scale set to use that preconfigured image where all the environment variables will already be set.
