Waiting for virtual machine to reach status 'provisioning'.................vm state 'provisioning' reached after 2.87 minutes.

DNS Name: azurelocalinstance.cloudapp.net

SSH Port: 22
Environment: _default

Waiting for sshd on 13.76.143.3:22done

Connecting to 13.76.143.3
Password: 
Failed to authenticate myuser - trying password auth
Enter your password:
ERROR: Net::SSH::AuthenticationFailed: Authentication failed for user myuser@13.76.143.3@13.76.143.3

Error the problem i faced was while trying to bootstrap the ssh authentication fails even though the rsa file is specified

the rsa key is genereated by the following code

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

any help is appreciated in advance

You need to configure the SSH key on the Azure side too. Simply providing a private key does nothing if the server is not configured to accept it. Knife automatically falls back to password authentication if the key fails (to mimic the behavior of OpenSSH).
