Appendix E. Installation failure on Ansible step "Add masters to requisite groups"
An issue can occur if another stack uses the
EC2 tag of
openshift_role but does not have an
KubernetesCluster. One possible work-around is to limit the regions that will be queried by the dynamic inventory script.
Modify regions = all to reflect a specific region.
# vi openshift-ansible-contrib/reference-architecture/aws-ansible/inventory/aws/hosts/ec2.ini regions = us-east-1
Another option would be to temporarily stop the other instances until the installation is completed.
