openshift-ansible: Unable to restart service origin-master-api

I’m trying to install Openshift Origin using Openshift Ansible on my server but I encountered an error.

Unable to restart service origin-master-api: Job for origin-master-api.service failed because the control process exited with error code

Details as follows:

Ansible Version

Ansible 2.3.1.0

Server

Digital Ocean $10 server plan

My inventory.erb

[OSEv3:children]
masters
nodes

[OSEv3:vars]
ansible_ssh_user=root
deployment_type=origin
openshift_master_identity_providers=[{'name': 'htpasswd_auth', 'login': 'true', 'challenge': 'true', 'kind': 'HTPasswdPasswordIdentityProvider', 'filename':$
containerized=true
openshift_release=v1.5.0
openshift_image_tag=v1.5.0
openshift_public_hostname=console.dampi.ph

openshift_disable_check=memory_availability,disk_availability,docker_storage

openshift_master_overwrite_named_certificates=true
openshift_master_named_certificates=[{"certfile": "/etc/letsencrypt/live/console.dampi.ph/cert.pem", "keyfile": "/etc/letsencrypt/live/console.dampi.ph/priv$


[masters]

[nodes]
console.dampi.ph openshift_node_labels="{'region': 'infra', 'zone': 'default'}" openshift_schedulable=true

[etcd]
console.dampi.ph

This is the result when I run systemctl status origin-master-api.service
