If you're not using a platform with cloud-init support (i.e., you're building a VM manually, not provisioning it through a cloud provider), you'll need to refer to [trick #1][atomic-trick1] and [#2][atomic-trick2] for a means to override the automated setup, apply a manual password to the CentOS account, and enable SSH password logins.
### Change to latest docker
Run the following on each node to replace the default docker 1.12 with docker 1.13 (_which we need for swarm mode_):

### Enable docker experimental features
In order to be able to watch the logs of any service from any manager node, we need to enable "experimental features" in docker. (It's no longer experimental in mainstream, but under the current Atomic).

{
"log-driver": "journald",

"log-driver": "journald",
"signature-verification": false,
"experimental": true

```
### Upgrade Atomic
Finally, apply any Atomic host updates, and reboot, by running: ```atomic host upgrade && systemctl reboot```.
### Permit connectivity between VMs
By default, Atomic only permits incoming SSH. We'll want to allow all traffic between our nodes, so add something like this to /etc/sysconfig/iptables:
