在Docker的必备配置SELinux上，Openshift安装失败（找不到semanage＆restorecon命令）

Question

规格：

• Openshift 3.11
• Ansible 2.6.19
• RHEL 7.6

Ansible无法运行prereqs安装，如下所示

ansible-playbook -i /etc/ansible/hosts /usr/share/ansible/openshift-ansible/playbooks/prerequisites.yml -vvv 

错误：

    "cmd": "semanage fcontext -a -e /var/lib/docker/overlay2 \"/var/lib/docker/overlay2\"\n restorecon -R -v \"/var/lib/docker/overlay2\"",

}

我遵循了以下网站的一些建议，但均因上述相同错误而失败

• [FAILED]在执行剧本时添加--become-method = sudo --become-user = root https://docs.ansible.com/ansible/2.4/become.html
