Appendix B. Installation Failure

The static inventory is used with the uninstall playbook to identify OpenShift nodes. Modify the inventory below to match the deployed environment or use the Ansible playbook located at openshift-ansible-contrib/reference-architecture/aws-ansible/playbooks/create-inventory-file.yaml to create an inventory.

Automated inventory creation

# cd /home/USER/git/openshift-ansible-contrib/reference-architecture/aws-ansible
# ansible-playbook -i inventory/aws/hosts -e 'region=us-east-1 stack_name=openshift-infra github_client_secret=c3cd9271ffb9f7258e135fcf3ea3a358cffa46b1 github_organization=["openshift"] console_port=443 wildcard_zone=apps.sysdeseng.com public_hosted_zone=sysdeseng.com playbooks/create-inventory-file.yaml

The uninstall playbook removes OpenShift related packages, ETCD, and removes any certificates that were created during the failed install.

ansible-playbook -i /home/user/inventory /usr/share/ansible/openshift-ansible/playbooks/adhoc/uninstall.yml

The playbook below is the same playbook that is ran once the deployment of AWS resources is completed. Replace the rhsm_user and rhsm_password, stack_name, set the wildcard_zone and public_hosted_zone relevant to the information in Route53 and optionally modify the AWS region in the event us-east-1 was not used..

ansible-playbook -i inventory/aws/hosts -e 'region=us-east-1 stack_name=openshift-infra
keypair=OSE-key public_hosted_zone=sysdeseng.com wildcard_zone=apps.sysdeseng.com
console_port=443 deployment_type=openshift-enterprise rhsm_user=RHSM_USER
rhsm_password=RHSM_PASSWORD rhsm_pool="Red Hat OpenShift Container Platform, Standard, 2-Core"
containerized=False github_client_id=e76865557b0417387b35 github_client_secret=c3cd9271ffb9f7258e135fcf3ea3a358cffa46b1
github_organization=["openshift"]' playbooks/openshift-install.yaml

Also, the ose-on-aws.py can be executed again but this must be done with caution. If any of the variables in ose-on-aws.py are changed the cloudformation may update causing the AWS components to change.

./ose-on-aws.py --rhsm-user=RHSM_USER --rhsm-password=RHSM_PASSWORD --public-hosted-zone=sysdeseng.com
