DNS config seem to affect subsequent tasks
or so it seems, as these rules for EPEL have been used in other projects and well tested. I think that's the second time I hit this. I don't have time yet to investigate but wanted to keep track of the problem.
TASK [base : configure DNS resolution] *****************************************
changed: [gnocchi.osci.io]
TASK [base : install Epel] *****************************************************
fatal: [gnocchi.osci.io]: FAILED! => {"changed": false, "failed": true, "msg": "Failure talking to yum: Cannot find a valid baseurl for repo: base/7/x86_64"}
