How do I run ansible-playbook on a private IP? - ssh

Question

I have a task to install Docker on a private ip. There are two azure virtual machines, one with a public IP, the other with a private one. How to start a playbook from the first machine to the second?
The first virtual machine -https://i.stack.imgur.com/VLPyD.png
And the second one is - https://i.stack.imgur.com/zE5Lq.png
Tried through the command ansible 10.0.1.5 -m ping
But in the end there was such a problem
