# Introduction
|
|
|
|
We start building our cloud with virtual machines. You could use bare-metal machines as well, the configuration would be the same. Given that most readers (myself included) will be using virtual infrastructure, from now on I'll be referring strictly to VMs.
|
|
|
|
## Ingredients
|
|
|
|
3 x Virtual Machines, each with:
|
|
* CentOS/Fedora Atomic
|
|
* At least 1GB RAM
|
|
* At least 20GB disk space (but it'll be tight)
|
|
* Connectivity to each other within the same subnet, and on a low-latency link (i.e., no WAN links)
|
|
|
|
## Preparation
|
|
|
|
### Install latest docker
|
|
```
|
|
systemctl disable docker --now
|
|
systemctl enable docker-latest --now
|
|
sed -i '/DOCKERBINARY/s/^#//g' /etc/sysconfig/docker
|
|
```
