Let me begin by saying there seems to be confusion regarding which branch in
the openshift-ansible github project you should be using for deploying
components of OpenShift Origin. The official documentation for installing the
cluster says to use the master branch, however I've found that the master
branch never works and you must use the specific release branch for it to be
successful.
With that said, it looks like the ansible scripts to deploy metrics are no
longer in the release branch (I'm trying release-3.6 at the moment), and only
in the master branch. When I try running the playbook from the master branch on
a brand new 3.6.0 cluster, I get the following output from ansible:
TASK [openshift_master : Ensure that Heapster has nodes to run on]
******************************************************************************************************
fatal: [openshift-master]: FAILED! => {"failed": true, "msg": "Unexpected
templating type error occurred on ({{
__schedulable_nodes_matching_selector['results']['results'][0]['items'] |
default([]) | length != 0 }}): object of type 'builtin_function_or_method' has
no len()"}
to retry, use: --limit
@/openshift-ansible/playbooks/openshift-metrics/config.retry
Any ideas?
