# Customize with Cloud-Config
|

# Customize CoreOS with Cloud-Config
|
||||
|
||||
CoreOS allows you to configure networking, create users, launch systemd units on startup and more. We've designed our implementation to allow the same cloud-config file to work across all of our supported platforms.
|
||||
|
||||
Only a subset of [cloud-config functionality][cloud-config] is implemented. A set of custom parameters were added to the cloud-config format that are specific to CoreOS. An example file containing all available options can be found at the bottom of this page.

## CoreOS Parameters
|
||||
## Supported cloud-config Parameters
|
||||
|
||||
### coreos.etcd
|
||||
### ssh_authorized_keys
|
||||
|
||||
The `coreos.etcd.*` options are 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...
|
||||
Provided public SSH keys will be authorized for the `core` user.
|
||||
|
||||
```
|
||||
#cloud-config
|
||||
The keys will be named "coreos-cloudinit" by default.
|
||||
Override this with the `--ssh-key-name` flag when calling `coreos-cloudinit`.
|
||||
|
||||
coreos:
|
||||
etcd:
|
||||
name: node001
|
||||
discovery: https://discovery.etcd.io/3445fa65423d8b04df07f59fb40218f8
|
||||
addr: $public_ipv4:4001
|
||||
peer-addr: $private_ipv4:7001
|
||||
```
|
||||
### hostname
|
||||
|
||||
...will generate a systemd unit drop-in like this:
|
||||
The provided value will be used to set the system's hostname.
|
||||
This is the local part of a fully-qualified domain name (i.e. `foo` in `foo.example.com`).
|
||||
|
||||
```
|
||||
[Service]
|
||||
Environment="ETCD_NAME=node001"
|
||||
Environment="ETCD_DISCOVERY=https://discovery.etcd.io/3445fa65423d8b04df07f59fb40218f8"
|

Environment="ETCD_ADDR=203.0.113.29:4001"
|
||||
Environment="ETCD_PEER_ADDR=192.0.2.13:7001"
|
||||
```
|
||||
### users
|
||||
|
||||
For more information about the available configuration options, see the [etcd documentation][etcd-config].
|
||||
Note that hyphens in the coreos.etcd.* keys are mapped to underscores.
|
||||
Add or modify users with the `users` directive by providing a list of user objects, each consisting 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.
|
||||
|
||||
[etcd-config]: https://github.com/coreos/etcd/blob/master/Documentation/configuration.md
|
||||
- **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 createion.
|
||||
- **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
|
||||
- **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.
|
||||
|
||||
##### Generating a password hash
|
||||
|
||||
Generating a safe hash is important to the security of your system. Currently with updated tools like [oclhashcat](http://hashcat.net/oclhashcat/) simplified hashes like md5crypt are trivial to crack on modern GPU hardware. You can generate a "safer" hash (read: not safe, never publish your hashes publicly) via:
|
||||
|
||||
###### On Debian/Ubuntu (via the package "whois")
|
||||
mkpasswd --method=SHA-512 --rounds=4096
|
||||
|
||||
###### With OpenSSL (note: this will only make md5crypt. While better than plantext it should not be considered fully secure)
|
||||
openssl passwd -1
|
||||
|
||||
###### With Python (change password and salt values)
|
||||
python -c "import crypt, getpass, pwd; print crypt.crypt('password', '\$6\$SALT\$')"
|
||||
|
||||
###### With 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.
|
||||
|
||||
### write_files
|
||||
|
||||
Inject an arbitrary set of files to the local filesystem.
|
||||
Provide a list of objects with the following attributes:
|
||||
|
||||
- **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>`.
|
||||
|
||||
## Custom cloud-config Parameters
|
||||
|
||||
### coreos.oem
|
||||
|
||||
These fields are borrowed from the [os-release spec][os-release] and repurposed
|
||||
as a way for coreos-cloudinit to know about the OEM partition on this machine:
|
||||
as a way for cloud-init 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
|
||||
- **id**: A lower case string identifying the oem.
|
||||
- **version-id**: A lower case string identifying the version of the OEM. Example: `168.0.0`
|
||||
- **name**: A name without the version that is suitable for presentation to the user.
|
||||
- **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 partition.
|
||||
|
||||
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...
|
||||
cloudinit must render these fields down to an /etc/oem-release file on disk in the following format:
|
||||
|
||||
```
|
||||
#cloud-config
|
||||
coreos:
|
||||
oem:
|
||||
id: rackspace
|
||||
name: Rackspace Cloud Servers
|
||||
version-id: 168.0.0

|
||||
bug-report-url: https://github.com/coreos/coreos-overlay
|
||||
```
|
||||
|
||||
...would be rendered to the following `/etc/oem-release`:

|
||||
|
||||
### coreos.etcd.discovery_url
|
||||
|
||||
The value of `coreos.etcd.discovery_url` will be used to discover the instance's etcd peers using the [etcd discovery protocol][disco-proto]. Usage of the [public discovery service][disco-service] is encouraged.
|
||||
|
||||
[disco-proto]: https://github.com/coreos/etcd/blob/master/Documentation/discovery-protocol.md
|
||||
[disco-service]: http://discovery.etcd.io
|
||||
|
||||
### coreos.units
|
||||
|
||||
Arbitrary systemd units may be provided in the `coreos.units` attribute.
|
||||
`coreos.units` is a list of objects 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.
|
||||
- **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.
|
||||
- **name**: string representing unit's name
|
||||
- **runtime**: boolean indicating whether or not to persist the unit across reboots. This is analagous to the `--runtime` flag to `systemd enable`.
|
||||
- **content**: plaintext string representing entire unit file
|
||||
|
||||
**NOTE:** The command field is ignored for all network, netdev, and link units. The systemd-networkd.service unit will be restarted in their place.
|
||||
See docker example below.
|
||||
|
||||
##### Examples
|
||||
## user-data Script
|
||||
|
||||
Write a unit to disk, automatically starting it.
|
||||
Simply set your user-data to a script where the first line is a shebang:

#### 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:
|
||||
### Inject configuration files
|
||||
|
||||
```
|
||||
# On Debian/Ubuntu (via the package "whois")
|
||||
mkpasswd --method=SHA-512 --rounds=4096
|
||||
#cloud-config
|
||||
|
||||
# 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"'
|
||||
write_files:
|
||||
- path: /etc/hosts
|
||||
contents: |
|
||||
127.0.0.1 localhost
|
||||
192.0.2.211 buildbox
|
||||
- path: /etc/resolv.conf
|
||||
contents: |
|
||||
nameserver 192.0.2.13
|
||||
nameserver 192.0.2.14
|
||||
```
|
||||
|
||||
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.
|
||||
|
||||
### write_files
|
||||
|
||||
Inject an arbitrary set of files to the local filesystem.
|
||||
Provide a list of objects with the following attributes:
|
||||
|
||||
- **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>`.

# coreos-cloudinit
|
||||
|
||||
coreos-cloudinit enables a user to customize CoreOS machines by providing either a cloud-config document or an executable script through user-data.
|
||||
coreos-cloudinit allows a user to customize CoreOS machines by providing either an executable script or a cloud-config document as instance user-data. See below to learn how to use these features.
|
||||
|
||||
## Configuration with cloud-config
|
||||
## Supported Cloud-Config Features
|
||||
|
||||
A subset of the [official cloud-config spec][official-cloud-config] is implemented by coreos-cloudinit.
|
||||
Additionally, several [CoreOS-specific options][custom-cloud-config] have been implemented to support interacting with unit files, bootstrapping etcd clusters, and more.
|
||||
All supported cloud-config parameters are [documented here][all-cloud-config].
|
||||
Only a subset of [cloud-config functionality][cloud-config] is implemented. A set of custom parameters were added to the cloud-config format that are specific to CoreOS, which are [documented here](https://github.com/coreos/coreos-cloudinit/tree/master/Documentation/cloud-config.md).
|
||||
|
||||
[official-cloud-config]: http://cloudinit.readthedocs.org/en/latest/topics/format.html#cloud-config-data
|
||||
[custom-cloud-config]: https://github.com/coreos/coreos-cloudinit/blob/master/Documentation/cloud-config.md#coreos-parameters
|
||||
[all-cloud-config]: https://github.com/coreos/coreos-cloudinit/tree/master/Documentation/cloud-config.md
|
||||
|
||||
The following is an example cloud-config document:
|
||||
|
||||
```
|
||||
#cloud-config
|
||||
|
||||
coreos:
|
||||
units:
|
||||
- name: etcd.service
|
||||
command: start
|
||||
|
||||
users:
|
||||
- name: core
|
||||
passwd: $1$allJZawX$00S5T756I5PGdQga5qhqv1
|
||||
|
||||
write_files:
|
||||
- path: /etc/resolv.conf
|
||||
content: |
|
||||
nameserver 192.0.2.2
|
||||
nameserver 192.0.2.3
|
||||
```
|
||||
|
||||
## Executing a Script
|
||||
|
||||
coreos-cloudinit supports executing user-data as a script instead of parsing it as a cloud-config document.
|
||||
Make sure the first line of your user-data is a shebang and coreos-cloudinit will attempt to execute it:
|
||||
|
||||
```
|
||||
#!/bin/bash
|
||||
|
||||
echo 'Hello, world!'
|
||||
```
|
||||
|
||||
## user-data Field Substitution
|
||||
|
||||
coreos-cloudinit will replace the following set of tokens in your user-data with system-generated values.
|
||||
|
||||
| Token | Description |
|
||||
| ------------- | ----------- |
|
||||
| $public_ipv4 | Public IPv4 address of machine |
|
||||
| $private_ipv4 | Private IPv4 address of machine |
|
||||
|
||||
These values are determined by CoreOS based on the given provider on which your machine is running.
|
||||
Read more about provider-specific functionality in the [CoreOS OEM documentation][oem-doc].
|
||||
|
||||
[oem-doc]: https://coreos.com/docs/sdk-distributors/distributors/notes-for-distributors/
|
||||
|
||||
For example, submitting the following user-data...
|
||||
|
||||
```
|
||||
#cloud-config
|
||||
coreos:
|
||||
etcd:
|
||||
addr: $public_ipv4:4001
|
||||
peer-addr: $private_ipv4:7001
|
||||
```
|
||||
|
||||
...will result in this cloud-config document being executed:
|
||||
|
||||
```
|
||||
#cloud-config
|
||||
coreos:
|
||||
etcd:
|
||||
addr: 203.0.113.29:4001
|
||||
peer-addr: 192.0.2.13:7001
|
||||
```
