fatal: [localhost] => Authentication or permission failure. In some cases, you may have been able to authenticate and did not have permissions on the remote directory. Consider changing the remote temp path in ansible.cfg to a path rooted in "/tmp". Failed command was: mkdir -p $HOME/.ansible/tmp/ansible-tmp-1403661775.03-87881370436819 && echo $HOME/.ansible/tmp/ansible-tmp-14036534175.03-87881370436819, exited with result 127
处理方法：
#yum -y install openssh-clients
Ansible正在容器中运行,试图连接到容器,因此您需要同时授权容器和root用户.容器必须是已知主机,并且必须授权root的公钥.例如：
RUN ssh-keyscan -t rsa 127.0.0.1 >>/root/.ssh/known_hosts
RUN cat /root/.ssh/id_rsa.pub >>/root/.ssh/authorized_keys
