Your identification has been saved in /home/centos/.ssh/id_rsa.
Your public key has been saved in /home/centos/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:HCHKTPqm18uju3Gmejxp9XEAip11VvO0E7ezGxE26Lo ansible-nitin
The key's randomart image is:
+---[RSA 2048]----+

ansible.builtin.user:
name: "centos"
groups: docker
