I tried to use docker-storage-setup on a disk that was larger than 2TB: ``` # lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 558.4G 0 disk ├─sda1...

Deploy etcd nodes on OpenStack Controller nodes

Due to storage latency requirements for etcd, we found in 3.4 testing that putting etcd inside a VM backed by rotational disks (via ceph) was unstable. We moved etcd to...

DNS server on bastion host should serve wildcard for apps

The Heat templates deploy a DNS server. Can this server also (optionally) serve out the wildcard entry required for openshift routes?

For large scale deployments, we are recommending dedicated nodes be used for etcd. The heat templates currently do not support dedicated etcd nodes. Please add support for that. @lebauce has...

We use pre-built VM images that have storage already configured and images pre-pulled. Running docker-storage-setup again causes the installation to fail. Can you create a new knob docker_storage_setup: False to...

We have an appliance that requires ulimits and modprobe(blacklist) tuning. e.g. ```​/etc/security/limits.d/custom-limits.conf``` or ```/etc/modprobe.d/blacklist-custom-module.conf``` It might be possible to (ugly) implement this with the script.sh feature in tuned. Unless you...
