Doc Type: Bug Fix
Doc Text:
In multi-master environments if ansible_host and openshift_hostname values differ and ansible sorts one of the lists differently from the other then the CA Host may be the first master but it was still signing the initial certificates with the hostnames of the first master. By ensuring that we use the hostnames of the CA Host when creating the certificate authority we ensure that the certificates are signed with the correct hostnames even if the two lists are sorted differently.

Proposed fix here https://github.com/openshift/openshift-ansible/pull/3885

Comment 11 Scott Dodson 2017-05-02 15:52:36 UTC
Example where ansible_host sorts differently from openshift_hostname, in this case oo_first_master will be master1 but openshift_ca will be master2 :

master1  ansible_host= openshift_ip= openshift_public_ip= openshift_hostname= openshift_public_hostname=
master2  ansible_host= openshift_ip= openshift_public_ip= openshift_hostname= openshift_public_hostname=
master3  ansible_host= openshift_ip= openshift_public_ip= openshift_hostname= openshift_public_hostname=

Comment 13 Gaoyun Pei 2017-05-08 10:27:39 UTC
Verify this bug with openshift-ansible-3.4.82-1.git.0.c78ff1c.el7, after installation, all masters' certs were signed with correct ip address.
