-# Deprecated Cloud-Config Features

-## Retrieving SSH Authorized Keys
-
-### From a GitHub User
-
-Using the `coreos-ssh-import-github` field, we can import public SSH keys from a GitHub user to use as authorized keys to a server.
-
-```yaml
-#cloud-config
-
-users:
-  - name: elroy
-    coreos-ssh-import-github: elroy
-```
-
-### From an HTTP Endpoint
-
-We can also pull public SSH keys from any HTTP endpoint which matches [GitHub's API response format](https://developer.github.com/v3/users/keys/#list-public-keys-for-a-user).
-For example, if you have an installation of GitHub Enterprise, you can provide a complete URL with an authentication token:
-
-```yaml
-#cloud-config
-
-users:
-  - name: elroy
-    coreos-ssh-import-url: https://github-enterprise.example.com/api/v3/users/elroy/keys?access_token=<TOKEN>
-```
-
-You can also specify any URL whose response matches the JSON format for public keys:
-
-```yaml
-#cloud-config
-
-users:
-  - name: elroy
-    coreos-ssh-import-url: https://example.com/public-keys

-# Cloud-Config Locations
-
-On every boot, coreos-cloudinit looks for a config file to configure your host. Here is a list of locations which are used by the Cloud-Config utility, depending on your CoreOS platform:
-
-Location | Description
---- | --- | ---
-|`/media/configvirtfs/openstack/latest/user_data`|`/media/configvirtfs` mount point with [config-2](/os/docs/latest/config-drive.html#contents-and-format) label. It should contain a `openstack/latest/user_data` relative path. Usually used by cloud providers or in VM installations.|
-|`/media/configdrive/openstack/latest/user_data`|FAT or ISO9660 filesystem with [config-2](/os/docs/latest/config-drive.html#qemu-virtfs) label and `/media/configdrive/` mount point. It should also contain a `openstack/latest/user_data` relative path. Usually used in installations which are configured by USB Flash sticks or CDROM media.|
-|Kernel command line: `cloud-config-url=http://example.com/user_data`.| You can find this string using this command `cat /proc/cmdline`. Usually used in [PXE](/os/docs/latest/booting-with-pxe.html) or [iPXE](/os/docs/latest/booting-with-ipxe.html) boots.|
-|`/var/lib/coreos-install/user_data`| When you install CoreOS manually using the [coreos-install](/os/docs/latest/installing-to-disk.html) tool. Usually used in bare metal installations.|
-|`/usr/share/oem/cloud-config.yml`| Path for OEM images.|
-|`/var/lib/coreos-vagrant/vagrantfile-user-data`| Vagrant OEM scripts automatically store Cloud-Config into this path. |
-|`/var/lib/waagent/CustomData`| Azure platform uses OEM path for first Cloud-Config initialization and then `/var/lib/waagent/CustomData` to apply your settings.|
-|`http://169.254.169.254/metadata/v1/user-data` `http://169.254.169.254/2009-04-04/user-data` `https://metadata.packet.net/userdata`|DigitalOcean, EC2 and Packet cloud providers correspondingly use these URLs to download Cloud-Config.|
-|`/usr/share/oem/bin/vmtoolsd --cmd "info-get guestinfo.coreos.config.data"`|Cloud-Config provided by [VMware Guestinfo][VMware Guestinfo]|
-|`/usr/share/oem/bin/vmtoolsd --cmd "info-get guestinfo.coreos.config.url"`|Cloud-Config URL provided by [VMware Guestinfo][VMware Guestinfo]|

-sudo coreos-cloudinit --from-file=/home/core/cloud-config.yaml

-## Cloud-Config VMWare Guestinfo Variables
-
-coreos-cloudinit accepts configuration from the VMware RPC API's *guestinfo*
-facility. This datasource can be enabled with the `--from-vmware-guestinfo`
-flag to coreos-cloudinit.
-
-The following guestinfo variables are recognized and processed by cloudinit
-when passed from the hypervisor to the virtual machine at boot time. Note that
-property names are prefixed with `guestinfo.` in the VMX, e.g., `guestinfo.hostname`.
-
-|            guestinfo variable             |              type               |

-| `interface.<n>.mac`                   | `MAC address`                   |

-Note: "n", "m", "l", and "x" are 0-indexed, incrementing integers. The
-identifier for an `interface` does not correspond to anything outside of this
-configuration; it serves only to distinguish between multiple `interface`s.

-The guide to [booting on VMWare][bootvmware] is the starting point for more
-information about configuring and running CoreOS on VMWare.
