So far I could work around by not setting "openshift_release: v3.7" in provisioning_vars.yml, if this looks good to you, it could be fix by modify the document.

# cat provisioning_vars.yml.example
...
# openshift_release must be specified.  Use whatever version of openshift
# that is supported by openshift-ansible that you wish.
#openshift_release: # v3.7

...

# cat /usr/share/ansible/openshift-ansible/playbooks/aws/README.md
...
# Minimum mandatory provisioning variables.  See provisioning_vars.yml.example.
# for more information.
openshift_deployment_type: # 'origin' or 'openshift-enterprise'
openshift_release: # example: v3.7
openshift_pkg_version: # example: -3.7.0
openshift_aws_ssh_key_name: # example: myuser_key
openshift_aws_base_ami: # example: ami-12345678
openshift_aws_iam_cert_path: # example: '/path/to/wildcard.<clusterid>.example.com.crt'
openshift_aws_iam_key_path: # example: '/path/to/wildcard.<clusterid>.example.com.key'

Wenkai,

Thanks for looking at this openshift_version issue.  Could you also try using 'openshift_version: 3.7'?  I think that the 'v' in 'v3.7' is causing the issue.

I generally specify 'openshift_pkg_version=-3.7.0' in my inventory file and this solves the version.

Thanks.

Kenny,

I try to use "openshift_version: 3.7" in provisioning_vars.yml, it still failed.

I'm wonder if "openshift_release: v3.7" necessary in provisioning_vars.yml? Cause "openshift_release: v3.7" could setting in inventory.yml which works very well.

# cat provisioning_vars.yml
...
# openshift_release must be specified.  Use whatever version of openshift
# that is supported by openshift-ansible that you wish.
#openshift_release: # v3.7
openshift_release: 3.7
...

# ansible-playbook -i inventory.yml /usr/share/ansible/openshift-ansible/playbooks/aws/openshift-cluster/build_ami.yml -e @provisioning_vars.yml -vvv

Kenny, Russ, and Mike to brainstorm and come up with a solution for avoiding use of extra vars. Since CI/CD/Ops teams are not blocked by this we're pushing this out to 3.10 but if we can fix it before 3.9 that's fine too.
