Automating VM creation: Difference between revisions

The below virtual machine (VM) setup files are intended to be used to quickly create VMs and clusters of VMs. The files come in two forms, [https://wiki.openstack.org/wiki/Heat Heat] templates, and [https://cloudinit.readthedocs.io/en/latest/ CloudInit] files; both use the [https://en.wikipedia.org/wiki/YAML YAML] file format. CloudInit files are used to initialize a particular VM and run within that VM. They can be used to update the operating system, install and configuring applications, create files, run commands, and create users and groups. Heat templates are even more powerful. They can create multiple VMs at once, configure security groups to access VMs from the outside world, create and configure networks, create and attach volumes to VMs, and pass information about other resources to CloudInit (e.g. floating IPs). They can also be used in conjunction with CloudInit files.
