# /etc/ansible/hosts... openshift_enable_service_catalog=falsetemplate_service_broker_install=falseansible_service_broker_install=false...
关闭etcd目录的selinux检查
关闭任务Check selinux label of '{{ etcd_data_dir }}'与Make sure the '{{ etcd_data_dir }}' has the proper label
# roles/etcd/tasks/backup/backup.yml...
- name: Detecting Atomic Host Operating System stat:
path: /run/ostree-booted
