fatal: [10.11.16.8]: FAILED! => {"msg": "Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this. Please add this host's fingerprint to your known_hosts file to manage this host."}

解决办法：
方式1、在hosts文件中用ssh秘钥
[user] 10.11.16.8 ansible_ssh_user=root ansible_ssh_port=32069 ansible_ssh_private_key_file=/root/.ssh/id_rsa
方式2、修改ansible配置文件，禁用ssh秘钥主机检查
vim /etc/ansible/ansible.cfg
# uncomment this to disable SSH key host checking host_key_checking = False
