+# Using 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. 
+
+## Configuration File
+
+The file used by this system initialization program is called a "cloud-config" file. It is inspired by the [cloud-init][cloud-init] project's [cloud-config][cloud-config] file. which is "the defacto multi-distribution package that handles early initialization of a cloud instance" ([cloud-init docs][cloud-init-docs]). Because the cloud-init project includes tools which aren't used by CoreOS, only the relevant subset of its configuration items will be implemented in our cloud-config file. In addition to those, we added a few CoreOS-specific items, such as etcd configuration, OEM definition, and systemd units.
+
+We've designed our implementation to allow the same cloud-config file to work across all of our supported platforms.

+[cloud-init-docs]: http://cloudinit.readthedocs.org/en/latest/index.html
+[cloud-config]: http://cloudinit.readthedocs.org/en/latest/topics/format.html#cloud-config-data
+
+### File Format
+
+The cloud-config file uses the [YAML][yaml] file format, which uses whitespace and new-lines to delimit lists, associative arrays, and values.
+
+A cloud-config file should contain an associative array which has zero or more of the following keys:
+
+- `coreos`
+- `ssh_authorized_keys`
+- `hostname`
+- `users`
+- `write_files`
+- `manage_etc_hosts`
+
+The expected values for these keys are defined in the rest of this document.
+
+[yaml]: https://en.wikipedia.org/wiki/YAML
+
+### Providing Cloud-Config with Config-Drive
+
+CoreOS tries to conform to each platform's native method to provide user data. Each cloud provider tends to be unique, but this complexity has been abstracted by CoreOS. You can view each platform's instructions on their documentation pages. The most universal way to provide cloud-config is [via config-drive](https://github.com/coreos/coreos-cloudinit/blob/master/Documentation/config-drive.md), which attaches a read-only device to the machine, that contains your cloud-config file.
+
+## Configuration Parameters
+
+### coreos
+
+#### etcd
+
+The `coreos.etcd.*` parameters will be translated to a partial systemd unit acting as an etcd configuration file.
+We can use the templating feature of coreos-cloudinit to automate etcd configuration with the `$private_ipv4` and `$public_ipv4` fields. For example, the following cloud-config document...
+
+```
+#cloud-config
+
+coreos:
+    etcd:
+        name: node001
+	# generate a new token for each unique cluster from https://discovery.etcd.io/new
+        discovery: https://discovery.etcd.io/<token>
+	# multi-region and multi-cloud deployments need to use $public_ipv4
+        addr: $public_ipv4:4001
+        peer-addr: $private_ipv4:7001
+```
+
+...will generate a systemd unit drop-in like this:
+
+```
+[Service]
+Environment="ETCD_NAME=node001"
+Environment="ETCD_DISCOVERY=https://discovery.etcd.io/<token>"
+Environment="ETCD_ADDR=203.0.113.29:4001"
+Environment="ETCD_PEER_ADDR=192.0.2.13:7001"
+```
+
+For more information about the available configuration parameters, see the [etcd documentation][etcd-config].
+Note that hyphens in the coreos.etcd.* keys are mapped to underscores.
+
+[etcd-config]: https://github.com/coreos/etcd/blob/master/Documentation/configuration.md
+
+#### oem
+
+The `coreos.oem.*` parameters follow the [os-release spec][os-release], but have been repurposed as a way for coreos-cloudinit to know about the OEM partition on this machine:
+
+- **id**: Lowercase string identifying the OEM
+- **name**: Human-friendly string representing the OEM
+- **version-id**: Lowercase string identifying the version of the OEM
+- **home-url**: Link to the homepage of the provider or OEM
+- **bug-report-url**: Link to a place to file bug reports about this OEM
+
+coreos-cloudinit renders these fields to `/etc/oem-release`.
+If no **id** field is provided, coreos-cloudinit will ignore this section.
+
+For example, the following cloud-config document...
+
+```
+#cloud-config
+coreos:
+  oem:
+    id: rackspace
+    name: Rackspace Cloud Servers
+    version-id: 168.0.0
+    home-url: https://www.rackspace.com/cloud/servers/
+    bug-report-url: https://github.com/coreos/coreos-overlay
+```
+
+...would be rendered to the following `/etc/oem-release`:
+
+```
+ID=rackspace
+NAME="Rackspace Cloud Servers"
+VERSION_ID=168.0.0
+HOME_URL="https://www.rackspace.com/cloud/servers/"
+BUG_REPORT_URL="https://github.com/coreos/coreos-overlay"
+```
+
+[os-release]: http://www.freedesktop.org/software/systemd/man/os-release.html
+
+#### units
+
+The `coreos.units.*` parameters define a list of arbitrary systemd units to start. Each item is an object with the following fields:
+
+- **name**: String representing unit's name. Required.
+- **runtime**: Boolean indicating whether or not to persist the unit across reboots. This is analagous to the `--runtime` argument to `systemd enable`. Default value is false.
+- **enable**: Boolean indicating whether or not to handle the [Install] section of the unit file. This is similar to running `systemctl enable <name>`. Default value is false.
+- **content**: Plaintext string representing entire unit file. If no value is provided, the unit is assumed to exist already.
+- **command**: Command to execute on unit: start, stop, reload, restart, try-restart, reload-or-restart, reload-or-try-restart. Default value is restart.
+
+**NOTE:** The command field is ignored for all network, netdev, and link units. The systemd-networkd.service unit will be restarted in their place.
+
+##### Examples
+
+Write a unit to disk, automatically starting it.
+
+```
+#cloud-config
+
+coreos:
+    units:
+      - name: docker-redis.service
+        content: |
+          [Unit]
+          Description=Redis container
+          Author=Me
+          After=docker.service
+
+          [Service]
+          Restart=always
+          ExecStart=/usr/bin/docker start -a redis_server
+          ExecStop=/usr/bin/docker stop -t 2 redis_server
+          
+          [Install]
+          WantedBy=local.target
+```
+
+Start the builtin `etcd` and `fleet` services:
+
+```
+# cloud-config
+
+coreos:
+    units:
+      - name: etcd.service
+        command: start
+      - name: fleet.service
+        command: start
+```
+
+### ssh_authorized_keys
+
+The `ssh_authorized_keys` parameter adds public SSH keys which will be authorized for the `core` user.
+
+The keys will be named "coreos-cloudinit" by default.
+Override this by using the `--ssh-key-name` flag when calling `coreos-cloudinit`.
+
+```
+#cloud-config
+
+ssh_authorized_keys:
+  - ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC0g+ZTxC7weoIJLUafOgrm+h...
+```
+
+### hostname
+
+The `hostname` parameter defines the system's hostname.
+This is the local part of a fully-qualified domain name (i.e. `foo` in `foo.example.com`).
+
+```
+#cloud-config
+
+hostname: coreos1
+```
+
+### users
+
+The `users` parameter adds or modifies the specified list of users. Each user is an object which consists of the following fields. Each field is optional and of type string unless otherwise noted.
+All but the `passwd` and `ssh-authorized-keys` fields will be ignored if the user already exists.
+
+- **name**: Required. Login name of user
+- **gecos**: GECOS comment of user
+- **passwd**: Hash of the password to use for this user
+- **homedir**: User's home directory. Defaults to /home/<name>
+- **no-create-home**: Boolean. Skip home directory creation.
+- **primary-group**: Default group for the user. Defaults to a new group created named after the user.
+- **groups**: Add user to these additional groups
+- **no-user-group**: Boolean. Skip default group creation.
+- **ssh-authorized-keys**: List of public SSH keys to authorize for this user
+- **coreos-ssh-import-github**: Authorize SSH keys from Github user
+- **coreos-ssh-import-url**: Authorize SSH keys imported from a url endpoint.
+- **system**: Create the user as a system user. No home directory will be created.
+- **no-log-init**: Boolean. Skip initialization of lastlog and faillog databases.
+
+The following fields are not yet implemented:
+
+- **inactive**: Deactivate the user upon creation
+- **lock-passwd**: Boolean. Disable password login for user
+- **sudo**: Entry to add to /etc/sudoers for user. By default, no sudo access is authorized.
+- **selinux-user**: Corresponding SELinux user
+- **ssh-import-id**: Import SSH keys by ID from Launchpad.
+
+```
+#cloud-config
+
+users:
+  - name: elroy
+    passwd: $6$5s2u6/jR$un0AvWnqilcgaNB3Mkxd5yYv6mTlWfOoCYHZmfi3LDKVltj.E8XNKEcwWm...
+    groups:
+      - sudo
+      - docker
+    ssh-authorized-keys:
+      - ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC0g+ZTxC7weoIJLUafOgrm+h...
+```
+
+#### Generating a password hash
+
+If you choose to use a password instead of an SSH key, generating a safe hash is extremely important to the security of your system. Simplified hashes like md5crypt are trivial to crack on modern GPU hardware. Here are a few ways to generate secure hashes:
+
+```
+# On Debian/Ubuntu (via the package "whois")
+mkpasswd --method=SHA-512 --rounds=4096
+
+# OpenSSL (note: this will only make md5crypt.  While better than plantext it should not be considered fully secure)
+openssl passwd -1
+
+# Python (change password and salt values)
+python -c "import crypt, getpass, pwd; print crypt.crypt('password', '\$6\$SALT\$')"
+
+# Perl (change password and salt values)
+perl -e 'print crypt("password","\$6\$SALT\$") . "\n"'
+```
+
+Using a higher number of rounds will help create more secure passwords, but given enough time, password hashes can be reversed.  On most RPM based distributions there is a tool called mkpasswd available in the `expect` package, but this does not handle "rounds" nor advanced hashing algorithms. 
+
+#### 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.
+
+```
+#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:
+
+```
+#cloud-config
+
+users:
+  - name: elroy
+    coreos-ssh-import-url: https://token:<OAUTH-TOKEN>@github-enterprise.example.com/users/elroy/keys
+```
+
+You can also specify any URL whose response matches the JSON format for public keys:
+
+```
+#cloud-config
+
+users:
+  - name: elroy
+    coreos-ssh-import-url: https://example.com/public-keys
+```
+
+### write_files
+
+The `write-file` parameter defines a list of files to create on the local filesystem. Each file is represented as an associative array which has the following keys:
+
+- **path**: Absolute location on disk where contents should be written
+- **content**: Data to write at the provided `path`
+- **permissions**: String representing file permissions in octal notation (i.e. '0644')
+- **owner**: User and group that should own the file written to disk. This is equivalent to the `<user>:<group>` argument to `chown <user>:<group> <path>`.
+
+Explicitly not implemented is the **encoding** attribute.
+The **content** field must represent exactly what should be written to disk.
+
+### manage_etc_hosts
+
+The `manage_etc_hosts` parameter configures the contents of the `/etc/hosts` file, which is used for local name resolution.
+Currently, the only supported value is "localhost" which will cause your system's hostname
+to resolve to "127.0.0.1".  This is helpful when the host does not have DNS
+infrastructure in place to resolve its own hostname, for example, when using Vagrant.
+
+```
+#cloud-config
+
+manage_etc_hosts: localhost
+```

+# Distribution via Config Drive
+
+CoreOS supports providing configuration data via [config drive][config-drive]
+disk images. Currently only providing a single script or cloud config file is
+supported.
+
+[config-drive]: http://docs.openstack.org/user-guide/content/enable_config_drive.html#config_drive_contents
+
+## Contents and Format
+
+The image should be a single FAT or ISO9660 file system with the label
+`config-2` and the configuration data should be located at
+`openstack/latest/user_data`.
+
+For example, to wrap up a config named `user_data` in a config drive image:
+
+    mkdir -p /tmp/new-drive/openstack/latest
+    cp user_data /tmp/new-drive/openstack/latest/user_data
+    mkisofs -R -V config-2 -o configdrive.iso /tmp/new-drive
+    rm -r /tmp/new-drive
+
+## QEMU virtfs
+
+One exception to the above, when using QEMU it is possible to skip creating an
+image and use a plain directory containing the same contents:
+
+    qemu-system-x86_64 \
+        -fsdev local,id=conf,security_model=none,readonly,path=/tmp/new-drive \
+        -device virtio-9p-pci,fsdev=conf,mount_tag=config-2 \
+        [usual qemu options here...]

Michael Marineau	78d8be8427	fix(units): Relax ordering requirements for now. The current cloudinit implementation blocks when starting units which causes it to deadlock the boot process if a system cloud config starts a user cloud config because the user configs want to run after system is done. Until cloudinit switches to non-blocking calls user configs will go back to just depending on coreos-setup-environment.service.	2014-04-14 21:39:40 -04:00
