Azure Cloud Shell - Sandbox sudo password

Question

Azure Cloud Shell - Sandbox sudo password

V, Desika (Cognizant) 101

Hi Team,

I'm trying to create a Linux VM using Azure CLI commands in sandbox. VM has been created. To run the command 'sudo apt-get update', I need to get the password so that I can proceed further on my learning. But I'm not sure about the password. Please help as I'm new to this concept.

@V, Desika (Cognizant) , Apologies for the delay from over the weekend.

As I understand you have provisioned the VM with password authentication and not SSH key via Cloud Shell>CLI. Could you please let us know which specific Learn module you are leveraging?
https://learn.microsoft.com/training/browse/?products=azure&terms=virtual%20machine

If there are any incomplete/clarity missing in the Learn module on this, we will work on it and get it fixed. Kindly let us know, I’ll follow up with you further.

Edit for clarity:
I understand you’re using Azure CLI; added following, as FYI, as you’re looking to understand about locating the password.
Typically, you would need to use the root/password that was set while creating the Azure VM.

In case you have forgotten the password, you can reset credentials via “Reset password” via Azure Portal.

Just checkout create an administrative/sudo user, which outlines steps on updating a user's SSH key or password via Azure VMAccess Extension.

Happy Learning!

Hi @Anonymous ,

Thanks much for the reply and the guidance, I'll go through the links that you've provided.

FYI, I'm currently learning from the below module,

https://learn.microsoft.com/en-us/training/modules/describe-azure-compute-networking-services/

Here, we have the Exercise to create a new VM using CLI, I followed the instruction as below to create Linux VM,

az vm create \
--resource-group [sandbox resource group name] \
--name my-vm \
--image UbuntuLTS \
--admin-username azureuser \
--generate-ssh-keys

Later when I try to update (as per the instruction) it asked me for the password. I've created the VM using Azure portal (in other exercise), where I've provided the password and the VM is created, and I knew the password.

In this case, how should I create a VM in CLI with password authentication.

also please clarify the below,

1) I understood that we can create the VM in different ways (Azure portal, the Azure CLI, Azure PowerShell, or an Azure Resource Manager (ARM) template). I've successfully created the VM from Azure Portal and I beleive this password can't be used while creating a VM in CLI. Because here the VM is created through CLI from a sandbox. So, I guess the VM will be deleted once the sandbox has timed out.

Let me know if my understanding is right, Thanks in Advance!

@V, Desika (Cognizant) ,

Thanks for the follow-up.

As described in the module, it aims to help you get hands on creating Azure VM via Azure CLI, so I would suggest you continue with Azure CLI for VM creation. (and not via Azure portal)

I went through all the units 1 -14 of the module:
Exercise - Create an Azure Virtual Machin >> Task 1: Create a Linux virtual machine and install Nginx >> 1 (az vm create) and 2 steps (az vm extension set)

The bash script runs apt-get update and never prompted for a password.
Because if you look at the az vm create it uses generate-ssh-keys and not password.

-so, typically, it should not prompt for password. You don't have run the command manually.
By running the script, the command automatically runs 'sudo apt-get update' with the saved SSH key files.

If this is not the case, or you're receiving a prompt for password, please share a screenshot for a closer look.

"Yes, If the sandbox times out while you're in the middle of the lesson, you will lose all work up to that point.
In this case, you will have to reactivate the environment and go back to the beginning of the module to start over."

Screenshots from Unit 3 and 9 of the module ( from my repro)

@V, Desika (Cognizant) , Just following up, when you get a chance, please let us know if you were able to complete the Unit 3’, Task 1 -step 2 (invoking az vm extension set cmdlet), we want to ensure you’re not blocked for completing the remaining units or modules.

Please let us know if you have any further questions, we would be more than happy to assist you.

I am also having the same issue on this module. Not sure why I am being asked for a password when we never gave on when creating the VM.

Hello everyone, I hope you are well!!!

I tell you that I was suffering with the same problem. Don't worry, it's something very simple, when we execute the last command where the script comes, the exercise actually ends there, the next thing they tell us is a summary of what the script does (but you don't have to do what it says, it's just an explanation of what the script does), since the sudo apt-get update does not have to be executed, the script already does it on its own.

I hope to make myself understood and help you with your doubt .

In my case, the last code that had to be executed is the one in the screenshot and after that code, the exercise ends with that.

Adding the answer provided @TP on this thread: Sudo password for azure sandbox

You need to ssh to the vm you created before you can use sudo. Please see instructions below to complete the exercise.

Please activate new sandbox and create the VM as instructed in the exercise. After Task 1 finishes, make a note of the publicIpAddress that was assigned to the VM (e.g. 20.245.72.52). Start Task 2, and then when it errors out, follow steps below:

Connect to the newly-created VM using ssh (in cloud shell). You will need to substitute the publicIpAddress you noted above for <VM public ip address> below:

ssh azureuser@<VM public ip address>

Enter yes when you are prompted.

Copy and right-click -- paste the following three commands below in the cloud shell window. Wait for each to complete before pasting in the next command.

sudo apt-get update

sudo apt-get install -y nginx

echo "<html><body><h2>Welcome to Azure! My name is $(hostname).</h2></body></html>" | sudo tee -a /var/www/html/index.html

Performing the steps above should only add a couple of minutes to the process. Continue on in the module.

I have the same issue, when I am using ssh and the user with the public IP it says the access is denied.

To benefit the community, find the right answer, posting our discussion from comments.

You don’t have to manually run the command sudo apt-get update, the bash script takes care of invoking this automatically with elevated permissions.
(Unit 3, Task 1 -step 2- invoking az vm extension set cmdlet)

Yes, “if the sandbox times out while you're in the middle of the lesson, you will lose all work up to that point. You will have to reactivate the environment and go back to the beginning of the module to start over."

Thanks for your patience and co-operation, @V, Desika (Cognizant)

Ibrahim-1981, Just to confirm, are you running the command manually? As mentioned in the document steps, you don't have to run the command manually, the script would take care of running the cmdlet automatically.

I just wrote the "ssh azureuser@my VM public ip address" command and it worked for me. Thanks!
