SSH to AzureVM(packer node) using SSH keys instead of ssh_username and ssh_password

[Rajendra Kumar]

Hi All,

Currently while baking azure vm using packer we give "ssh_username and ssh_password" in config.json, due to security concerns we want to use ssh keys to SSH into the azure packer node instead of  "ssh_username and ssh_password" . 

I could not find any packer variable where can I specify the SSH keys, and could not find any example config.json on the internet.

can somebody please help how can I achieve this, if possible please mention the steps and post the sample config.json.

Thanks in advance!

Hello,

Maybe in there -> https://www.packer.io/docs/templates/communicator.html#ssh_private_key_file ?

Thanks Lovi !!

So "ssh_private_key_file" is where we give the private key to authenticate, how can we mention the public key which gets attached to AzurevM(packer node) ? 

Like in AWS we can attach a pem file while launching the machine and in config.json we can send the private key to authenticate.

Packer variable for AWS ec2 builder 

"ssh_private_key_file" : "<private_key_file>",
"ssh_keypair_name" : "<key-pair-name-while-luanching-ec2-machine>",

Do we have something similar to aws ec2 builder ?

You can simply skip ssh key file. If you skip this attribute, packer will create temporary key pair and use that for creating the image.
