100 days of cloud Azure - day 13

MrSampath · December 18, 2025, 5:49am

I am unable to complete Day 13: SSH into an Azure Virtual Machine. Can you please guide me with the steps required to complete it. I tried multiple times trying to copy the SSH public key to the “authorized file” but I am facing a permission issue.

MrSampath · December 18, 2025, 7:12am

I think I am able to SSH now. But still this task failed. Please confirm.

Hi @MrSampath

Please refer to the solution here:

## Task: SSH into an Azure Virtual Machine
The Nautilus DevOps team is working on setting up secure SSH access for their virtual machines in Azure. One of the requirements is to add the SSH public key of the root user from the Azure client host (landing host) to the `datacenter-vm` Azure VM's `authorized_keys` file. This ensures secure and password-less SSH access to the VM.

#### Task Details:
- **VM Details:**
  - The VM is named `datacenter-vm` and is running in the `West US` region. The default SSH user is `azureuser` — use this user to connect to the VM.
  - You need to add the root user's SSH public key from the Azure client host to the `authorized_keys` file of the VM's root user.
  - The SSH public key of the root user on the Azure client host is located at `/root/.ssh/id_rsa.pub`.
- **Public Key Addition:**
  - Copy the public key located at `/root/.ssh/id_rsa.pub` on the Azure client host to the `authorized_keys` file of the root user on `datacenter-vm`.
  - Ensure that the proper permissions for the `.ssh` folder and `authorized_keys` file are set on the VM.
- **Verification:**
  - After adding the public key, make sure that you are able to SSH into the `datacenter-vm` VM as the `root` user from the Azure client host without needing a password.

#### Important Notes:
- Ensure that the VM is up and running before attempting to SSH.
- You may need to adjust the firewall or security group rules for the VM to allow SSH access.

Thanks @MrSampath

I’ll check it and get back.

@MrSampath

It is valid issue, I’ve forwared to the team to check and update it.

I have also facing the same issue, I have completed the task and able to ssh with root user without password. But task given error on submission.

rob_kodekloud · December 24, 2025, 10:47pm

This one’s actually quite quick and easy:

Get a resource group for the azure-client’s account: az group list
Now use this command to get a public IP for our vm (say, xfusion-vm): az vm list-ip-addresses -g kml_rg_main-FROM-1 -n xfusion-vm
Get the public key for our azure-client: cat ~/.ssh/id_rsa.pub
ssh as azureuser to vm: ssh -i ~/.ssh/id_rsa azureuser@PUBLIC-IP
Become root: sudo -i
The /root/.ssh/authorized_keys` file has previous content – remove that and paste in the public key from the azure-client terminal from (3).
exit the vm.
test the vm by doing ssh -i ~/.ssh/id_rsa root@PUBLIC-IP.

That will pass the grader.

Thanks @rob_kodekloud

@Parveenrohilla

Please try again using Rob’s solution. I’m able to pass the task with it.

MrSampath · January 22, 2026, 12:30pm

Hi @raymond.baoly @rob_kodekloud

I tried the day 13 problem again today. Although I completed the task, still it shows that “task didnot completed successfully”. Attached is the screenshot.

raymond.baoly · January 23, 2026, 8:07am

Hi @MrSampath

I couldn’t replicate the issue. Please share your exact steps so I can see what went wrong.

MrSampath · January 24, 2026, 12:07pm

Hi @raymond.baoly

I followed the steps mentioned by rob_kodekloud (Dec '25 post).
If you see in the screenshot, I am able to login to the VM using the ssh -i ~/.ssh/id_rsa root@PUBLIC-IP code.(step8)

Because of which I have logged into VM and the cursor is at root@nautilus-vm.

raymond.baoly · January 27, 2026, 9:14am

Hi @MrSampath

I’m not sure what issue you’re facing, I’m still able to pass the task on my side.

Hi, rob_kodekloud!

Really enjoying the 100 days of Cloud Azure.

I’m currently stuck on day 13. I tried your method and raymond.baoly’s, but I’m still getting the permission denied error.

Here’s a screenshot. Can you please show me what I’m doing wrong?

Thank you!

rob_kodekloud · April 27, 2026, 7:07pm

Where are you trying to log in from? That looks like that might be cloudshell terminal; you will want to run ssh from the azure-client lab terminal. If you do that, the key pair already in the lab terminal will work to do this lab.

Jeremyz · April 28, 2026, 1:04am

I’ll try that. Thank you!

Jeremyz · April 29, 2026, 8:46pm

I finally passed! Thank you, sir!
