Hi all, need your help. I'm trying to deploy Openstack "Queens" via kolla on a multinode system (1 controller/kolla host + 1 compute). I tried with both binary and source packages and I'm using "ubuntu" as base_distro. The first attempt of deployment systematically fails here: TASK [mariadb : Running MariaDB bootstrap container] ******************************************************************************************************************************************************************************************************** fatal: [xx.yy.zz.136]: FAILED! => {"changed": true, "msg": "Container exited with non-zero return code 1"} Looking at the bootstrap_mariadb container logs I can see: ---------- Neither host 'xxyyzz' nor 'localhost' could be looked up with '/usr/sbin/resolveip' Please configure the 'hostname' command to return a correct hostname. ---------- Any idea ? Thanks a lot /Giuseppe
