I'm installing OpenShift for the first time on internal servers that were
provisioned and then configured by me. I had to host the repos internally
on our Artifactory server as the internal cluster has no direct internet
access. I followed all of the steps here:
https://docs.openshift.org/latest/install_config/install/prerequisites.html
and here:
https://docs.openshift.org/latest/install_config/install/advanced_install.html.
I'm installing it using openshift-ansible at
commit ac4ef6bb65c24890592b6b35b11be82f4ddc6deb. These systems are RHEL7.
My configuration file looks like below with minor edits to remove internal
information:
# Create an OSOv3 group that contains the master, nodes, etcd, and lb
groups.
# The lb group lets Ansible configure HAProxy as the load balancing
solution.
# Comment lb out if your load balancer is pre-configured.
[OSOv3:children]
masters
nodes
etcd
lb
# Set variables common for all OSOv3 hosts
[OSOv3:vars]
ansible_ssh_user=username
ansible_sudo=true
deployment_type=origin
# Uncomment the following to enable htpasswd authentication; defaults to
# DenyAllPasswordIdentityProvider.
openshift_master_identity_providers=[{'name': 'htpasswd_auth', 'login':
'true', 'challenge': 'true', 'kind': 'HTPasswdPasswordIdentityProvider',
'filename': '/etc/origin/master/htpasswd'}]
# Native high availability cluster method with optional load balancer.
# If no lb group is defined installer assumes that a load balancer has
# been preconfigured. For installation the value of
# openshift_master_cluster_hostname must resolve to the load balancer
# or to one or all of the masters defined in the inventory if no load
# balancer is present.
openshift_master_cluster_method=native
openshift_master_cluster_hostname=oshiftmst01.example.com
openshift_master_cluster_public_hostname=oshiftmst01.example.com
# host group for masters
[masters]
oshiftmst01.example.com
oshiftmst02.example.com
oshiftmst03.example.com
# host group for etcd
[etcd]
oshiftmst01.example.com
oshiftmst02.example.com
oshiftmst03.example.com
# Specify load balancer host
[lb]
oshiftinf01.example.com
# host group for nodes, includes region info
[nodes]
oshiftmst0[1:3].example.com openshift_node_labels="{'region': 'infra',
'zone': 'default'}"

Everything is installed correctly on the mst01 host and it starts
correctly. When I get to the mst02 host, it fails like this:
TASK [openshift_master : Start and enable master api]
**************************
fatal: [oshiftmst02.example.com]: FAILED! => {"changed": false, "failed":
true, "msg": "Job for origin-master-api.service failed because a timeout
was exceeded. See \"systemctl status origin-master-api.service\" and
\"journalctl -xe\" for details.\n"}
When I try to manually start it, I get this:
[username@oshiftmst02 ~]$ sudo systemctl start origin-master-api.service
Job for origin-master-api.service failed because a timeout was exceeded.
See "systemctl status origin-master-api.service" and "journalctl -xe" for
details.
When I look closer:

I thought that maybe the access wasn't open between masters, but curl works:
[username@oshiftmst02 ~]$ curl --insecure
https://oshiftmst01.example.com:8443
{
"paths": [
"/api",
"/api/v1",
"/apis",
"/controllers",
"/healthz",
"/healthz/ping",
"/healthz/ready",
"/metrics",
"/oapi",
"/oapi/v1",
"/swaggerapi/"
]
}
I'm assuming that I'm just not understanding the system well enough. Any
help would be appreciated.
