 # 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]|
 [VMware Guestinfo]: vmware-guestinfo.md
 You can also run the `coreos-cloudinit` tool manually and provide a path to your custom Cloud-Config file:
 ```sh
 sudo coreos-cloudinit --from-file=/home/core/cloud-config.yaml
 ```
 This command will apply your custom cloud-config.

+CoreOS allows you to declaratively customize various OS-level items, such as network configuration, user accounts, and systemd units. This document describes the full list of items we can configure. The `coreos-cloudinit` program uses these files as it configures the OS after startup or during runtime. Your cloud-config is processed during each boot.
 Your cloud-config is processed during each boot. Invalid cloud-config won't be processed but will be logged in the journal. You can validate your cloud-config with the [CoreOS validator]({{site.url}}/validate) or by running `coreos-cloudinit -validate`.
 In addition to `coreos-cloudinit -validate` command and https://coreos.com/validate/ online service you can debug `coreos-cloudinit` system output through the `journalctl` tool:
 ```sh
 journalctl _EXE=/usr/bin/coreos-cloudinit

 #### etcd2
 The `coreos.etcd2.*` parameters will be translated to a partial systemd unit acting as an etcd configuration file.
 If the platform environment supports the templating feature of coreos-cloudinit it is possible to automate etcd configuration with the `$private_ipv4` and `$public_ipv4` fields. When generating a [discovery token](https://discovery.etcd.io/new?size=3), set the `size` parameter, since etcd uses this to determine if all members have joined the cluster. After the cluster is bootstrapped, it can grow or shrink from this configured size.
 For example, the following cloud-config document...
 ```yaml
 #cloud-config
 coreos:
  etcd2:
    # generate a new token for each unique cluster from https://discovery.etcd.io/new?size=3
    discovery: "https://discovery.etcd.io/<token>"

    # listen on both the official ports and the legacy ports
    # legacy ports can be omitted if your application doesn't depend on them
    listen-client-urls: "http://0.0.0.0:2379,http://0.0.0.0:4001"
    listen-peer-urls: "http://$private_ipv4:2380,http://$private_ipv4:7001"
 ```
 ...will generate a systemd unit drop-in for etcd2.service with the following contents:

 - **encoding**: Optional. The encoding of the data in content. If not specified this defaults to the yaml document encoding (usually utf-8). Supported encoding types are:
    - **b64, base64**: Base64 encoded content
    - **gz, gzip**: gzip encoded content, for use with the !!binary tag
    - **gz+b64, gz+base64, gzip+b64, gzip+base64**: Base64 encoded gzip content
 Explicitly not implemented is the **encoding** attribute.
 The **content** field must represent exactly what should be written to disk.

 # VMWare Guestinfo Interface
 ## 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               |
 |:--------------------------------------|:--------------------------------|
 | `hostname`                            | `hostname`                      |
 | `interface.<n>.name`                  | `string`                        |
 | `interface.<n>.mac`                   | `MAC address`                   |
 | `interface.<n>.dhcp`                  | `{"yes", "no"}`                 |
 | `interface.<n>.role`                  | `{"public", "private"}`         |
 | `interface.<n>.ip.<m>.address`        | `CIDR IP address`               |
 | `interface.<n>.route.<l>.gateway`     | `IP address`                    |
 | `interface.<n>.route.<l>.destination` | `CIDR IP address`               |
 | `dns.server.<x>`                      | `IP address`                    |
 | `coreos.config.data`                  | `string`                        |
 | `coreos.config.data.encoding`         | `{"", "base64", "gzip+base64"}` |
 | `coreos.config.url`                   | `URL`                           |
 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.

 cepgo
 =====
 Cepko implements easy-to-use communication with CloudSigma's VMs through a
 virtual serial port without bothering with formatting the messages properly nor
 parsing the output with the specific and sometimes confusing shell tools for
 that purpose.
 Having the server definition accessible by the VM can be useful in various
 ways. For example it is possible to easily determine from within the VM, which
 network interfaces are connected to public and which to private network.
 Another use is to pass some data to initial VM setup scripts, like setting the
 hostname to the VM name or passing ssh public keys through server meta.
 Example usage:
    package main
    import (
            "fmt"
            "github.com/cloudsigma/cepgo"
    )
    func main() {
            c := cepgo.NewCepgo()
            result, err := c.Meta()
            if err != nil {
                    panic(err)
            }
            fmt.Printf("%#v", result)
    }
 Output:
    map[string]interface {}{
        "optimize_for":"custom",
        "ssh_public_key":"ssh-rsa AAA...",
        "description":"[...]",
    }

 go.dbus
 -------
 go.dbus is a simple library that implements native Go client bindings for the
 D-Bus message bus system.
 ### Features
 * Complete native implementation of the D-Bus message protocol
 * Go-like API (channels for signals / asynchronous method calls, Goroutine-safe connections)
 * Subpackages that help with the introspection / property interfaces
 ### Installation
 This packages requires Go 1.1. If you installed it and set up your GOPATH, just run:
 ```
 go get github.com/guelfey/go.dbus
 ```
 If you want to use the subpackages, you can install them the same way.
 ### Usage
 The complete package documentation and some simple examples are available at
 [godoc.org](http://godoc.org/github.com/guelfey/go.dbus). Also, the
 [_examples](https://github.com/guelfey/go.dbus/tree/master/_examples) directory
 gives a short overview over the basic usage. 
 Please note that the API is considered unstable for now and may change without
 further notice.
 ### License
 go.dbus is available under the Simplified BSD License; see LICENSE for the full

 /*
 Package dbus implements bindings to the D-Bus message bus system.
 To use the message bus API, you first need to connect to a bus (usually the
 session or system bus). The acquired connection then can be used to call methods
 on remote objects and emit or receive signals. Using the Export method, you can
 arrange D-Bus methods calls to be directly translated to method calls on a Go
 value.
 Conversion Rules
 For outgoing messages, Go types are automatically converted to the
 corresponding D-Bus types. The following types are directly encoded as their
 respective D-Bus equivalents:
     Go type     | D-Bus type
     ------------+-----------
     byte        | BYTE
     bool        | BOOLEAN
     int16       | INT16
     uint16      | UINT16
     int32       | INT32
     uint32      | UINT32
     int64       | INT64
     uint64      | UINT64
     float64     | DOUBLE
     string      | STRING
     ObjectPath  | OBJECT_PATH
     Signature   | SIGNATURE
     Variant     | VARIANT
     UnixFDIndex | UNIX_FD
 Slices and arrays encode as ARRAYs of their element type.
 Maps encode as DICTs, provided that their key type can be used as a key for
 a DICT.
 Structs other than Variant and Signature encode as a STRUCT containing their
 exported fields. Fields whose tags contain `dbus:"-"` and unexported fields will
 be skipped.
 Pointers encode as the value they're pointed to.
 Trying to encode any other type or a slice, map or struct containing an
 unsupported type will result in an InvalidTypeError.
 For incoming messages, the inverse of these rules are used, with the exception
 of STRUCTs. Incoming STRUCTS are represented as a slice of empty interfaces
 containing the struct fields in the correct order. The Store function can be
 used to convert such values to Go structs.
 Unix FD passing
 Handling Unix file descriptors deserves special mention. To use them, you should
 first check that they are supported on a connection by calling SupportsUnixFDs.
 If it returns true, all method of Connection will translate messages containing
 UnixFD's to messages that are accompanied by the given file descriptors with the
 UnixFD values being substituted by the correct indices. Similarily, the indices
 of incoming messages are automatically resolved. It shouldn't be necessary to use
 UnixFDIndex.

 GoSerial
 ========
 A simple go package to allow you to read and write from the
 serial port as a stream of bytes.
 Details
 -------
 It aims to have the same API on all platforms, including windows.  As
 an added bonus, the windows package does not use cgo, so you can cross
 compile for windows from another platform.  Unfortunately goinstall
 does not currently let you cross compile so you will have to do it
 manually:
    GOOS=windows make clean install
 Currently there is very little in the way of configurability.  You can
 set the baud rate.  Then you can Read(), Write(), or Close() the
 connection.  Read() will block until at least one byte is returned.
 Write is the same.  There is currently no exposed way to set the
 timeouts, though patches are welcome.
 Currently all ports are opened with 8 data bits, 1 stop bit, no
 parity, no hardware flow control, and no software flow control.  This
 works fine for many real devices and many faux serial devices
 including usb-to-serial converters and bluetooth serial ports.
 You may Read() and Write() simulantiously on the same connection (from
 different goroutines).
 Usage
 -----
 ```go
 package main
 import (
        "github.com/tarm/goserial"
        "log"
 )
 func main() {
        c := &serial.Config{Name: "COM45", Baud: 115200}
        s, err := serial.OpenPort(c)
        if err != nil {
                log.Fatal(err)
        }
        n, err := s.Write([]byte("test"))
        if err != nil {
                log.Fatal(err)
        }
        buf := make([]byte, 128)
        n, err = s.Read(buf)
        if err != nil {
                log.Fatal(err)
        }
        log.Print("%q", buf[:n])
 }
 ```
 Possible Future Work
 -------------------- 
 - better tests (loopback etc)
