# How to Contribute
|
||||
|
||||
CoreOS projects are [Apache 2.0 licensed](LICENSE) and accept contributions via
|
||||
GitHub pull requests. This document outlines some of the conventions on
|
||||
development workflow, commit message formatting, contact points and other
|
||||
resources to make it easier to get your contribution accepted.
|
||||
|
||||
# Certificate of Origin
|
||||
|
||||
By contributing to this project you agree to the Developer Certificate of
|
||||
Origin (DCO). This document was created by the Linux Kernel community and is a
|
||||
simple statement that you, as a contributor, have the legal right to make the
|
||||
contribution. See the [DCO](DCO) file for details.
|
||||
|
||||
# Email and Chat
|
||||
|
||||
The project currently uses the general CoreOS email list and IRC channel:
|
||||
- Email: [coreos-dev](https://groups.google.com/forum/#!forum/coreos-dev)
|
||||
- IRC: #[coreos](irc://irc.freenode.org:6667/#coreos) IRC channel on freenode.org
|
||||
|
||||
## Getting Started
|
||||
|
||||
- Fork the repository on GitHub
|
||||
- Read the [README](README.md) for build and test instructions
|
||||
- Play with the project, submit bugs, submit patches!
|
||||
|
||||
## Contribution Flow
|
||||
|
||||
This is a rough outline of what a contributor's workflow looks like:
|
||||
|
||||
- Create a topic branch from where you want to base your work (usually master).
|
||||
- Make commits of logical units.
|
||||
- Make sure your commit messages are in the proper format (see below).
|
||||
- Push your changes to a topic branch in your fork of the repository.
|
||||
- Make sure the tests pass, and add any new tests as appropriate.
|
||||
- Submit a pull request to the original repository.
|
||||
|
||||
Thanks for your contributions!
|
||||
|
||||
### Format of the Commit Message
|
||||
|
||||
We follow a rough convention for commit messages borrowed from AngularJS. This
|
||||
is an example of a commit:
|
||||
|
||||
```
|
||||
feat(scripts/test-cluster): add a cluster test command
|
||||
|
||||
this uses tmux to setup a test cluster that you can easily kill and
|
||||
start for debugging.
|
||||
```
|
||||
|
||||
The format can be described more formally as follows:
|
||||
|
||||
```
|
||||
<type>(<scope>): <subject>
|
||||
<BLANK LINE>
|
||||
<body>
|
||||
<BLANK LINE>
|
||||
<footer>
|
||||
```
|
||||
|
||||
The first line is the subject and should be no longer than 70 characters, the
|
||||
second line is always blank, and other lines should be wrapped at 80 characters.
|
||||
This allows the message to be easier to read on GitHub as well as in various
|
||||
git tools.
|
||||
|
||||
#### Subject Line
|
||||
|
||||
The subject line contains a succinct description of the change.
|
||||
|
||||
#### Allowed `<type>`s
|
||||
- *feat* (feature)
|
||||
- *fix* (bug fix)
|
||||
- *docs* (documentation)
|
||||
- *style* (formatting, missing semi colons, …)
|
||||
- *refactor*
|
||||
- *test* (when adding missing tests)
|
||||
- *chore* (maintain)
|
||||
|
||||
#### Allowed `<scope>`s
|
||||
|
||||
Scopes can anything specifying the place of the commit change in the code base -
|
||||
for example, "api", "store", etc.
|
||||
|
||||
|
||||
For more details on the commit format, see the [AngularJS commit style
|
||||
guide](https://docs.google.com/a/coreos.com/document/d/1QrDFcIiPjSLDn3EL15IJygNPiHORgU1_OOAqWjiDU5Y/edit#).

## OEM configuration
|
||||
|
||||
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. Customizing this section is only needed when generating a new OEM of CoreOS from the SDK. The fields include:
|
||||
|
||||
- **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...

# Using Cloud-Config
|
||||
# Customize CoreOS with 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.
|
||||
CoreOS allows you to configure machine parameters, launch systemd units on startup and more. 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.
|
||||
|
||||
## 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]: https://launchpad.net/cloud-init
|
||||
[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
|
||||
|
||||
#### fleet
|
||||
|
||||
The `coreos.fleet.*` parameters work very similarly to `coreos.etcd.*`, and allow for the configuration of fleet through environment variables. For example, the following cloud-config document...
|
||||
|
||||
```
|
||||
#cloud-config
|
||||
|
||||
coreos:
|
||||
fleet:
|
||||
public-ip: $public_ipv4
|
||||
metadata: region=us-west
|
||||
```
|
||||
|
||||
...will generate a systemd unit drop-in like this:
|
||||
|
||||
```
|
||||
[Service]
|
||||
Environment="FLEET_PUBLIC_IP=203.0.113.29"
|
||||
Environment="FLEET_METADATA=region=us-west"
|
||||
```
|
||||
|
||||
For more information on fleet configuration, see the [fleet documentation][fleet-config].
|
||||
|
||||
[fleet-config]: https://github.com/coreos/fleet/blob/master/Documentation/configuration.md
|
||||
|
||||
#### update
|
||||
|
||||
The `coreos.update.*` parameters manipulate settings related to how CoreOS instances are updated.
|
||||
|
||||
These fields will be written out to and replace `/etc/coreos/update.conf`. If only one of the parameters is given it will only overwrite the given field.
|
||||
The `reboot-strategy` parameter also affects the behaviour of [locksmith](https://github.com/coreos/locksmith).
|
||||
|
||||
- **reboot-strategy**: One of "reboot", "etcd-lock", "best-effort" or "off" for controlling when reboots are issued after an update is performed.
|
||||
- _reboot_: Reboot immediately after an update is applied.
|
||||
- _etcd-lock_: Reboot after first taking a distributed lock in etcd, this guarantees that only one host will reboot concurrently and that the cluster will remain available during the update.
|
||||
- _best-effort_ - If etcd is running, "etcd-lock", otherwise simply "reboot".
|
||||
- _off_ - Disable rebooting after updates are applied (not recommended).
|
||||
- **server**: is the omaha endpoint URL which will be queried for updates.
|
||||
- **group**: signifies the channel which should be used for automatic updates. This value defaults to the version of the image initially downloaded. (one of "master", "alpha", "beta", "stable")
|
||||
|
||||
*Note: cloudinit will only manipulate the locksmith unit file in the systemd runtime directory (`/run/systemd/system/locksmithd.service`). If any manual modifications are made to an overriding unit configuration file (e.g. `/etc/systemd/system/locksmithd.service`), cloudinit will no longer be able to control the locksmith service unit.*
|
||||
|
||||
##### Example
|
||||
|
||||
```
|
||||
#cloud-config
|
||||
coreos:
|
||||
update:
|
||||
reboot-strategy: etcd-lock
|
||||
```
|
||||
|
||||
#### 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 analogous to the `--runtime` argument to `systemctl 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.
|
||||
- **mask**: Whether to mask the unit file by symlinking it to `/dev/null` (analogous to `systemctl mask <name>`). Note that unlike `systemctl mask`, **this will destructively remove any existing unit file** located at `/etc/systemd/system/<unit>`, to ensure that the mask succeeds. Default value is false.
|
||||
|
||||
**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:
|
||||

|
||||
Restart=always
|
||||
ExecStart=/usr/bin/docker start -a redis_server
|
||||
ExecStop=/usr/bin/docker stop -t 2 redis_server
|
||||
```
|
||||
|
||||
Start the built-in `etcd` and `fleet` services:
|
||||
|
||||
```
|
||||
#cloud-config

||||
|
||||
coreos:

|
||||
- name: etcd.service
|
||||
command: start
|
||||
- name: fleet.service

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:

#### 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:
|
||||
###### With OpenSSL (note: this will only make md5crypt. While better than plantext it should not be considered fully secure)
|
||||
openssl passwd -1
|
||||
|
||||
```
|
||||
# On Debian/Ubuntu (via the package "whois")
|
||||
mkpasswd --method=SHA-512 --rounds=4096
|
||||
###### With Python (change password and salt values)
|
||||
python -c "import crypt, getpass, pwd; print crypt.crypt('password', '\$6\$SALT\$')"
|
||||
|

# 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"'
|
||||
```
|
||||
###### 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.

||||
#### 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://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:
|
||||
|
||||
```
|
||||
#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:
|
||||
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>`.
|
||||
|
||||
Explicitly not implemented is the **encoding** attribute.
|
||||
The **content** field must represent exactly what should be written to disk.
|
||||
## Custom cloud-config Parameters
|
||||
|
||||
### coreos.oem
|
||||
|
||||
These fields are borrowed from the [os-release spec][os-release] and repurposed
|
||||
as a way for cloud-init to know about the OEM partition on this machine.
|
||||
|
||||
- **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.
|
||||
|
||||
cloudinit must render these fields down to an /etc/oem-release file on disk in the following format:
|
||||
|
||||
```
|
||||
NAME=Rackspace
|
||||
ID=rackspace
|
||||
VERSION_ID=168.0.0
|
||||
PRETTY_NAME="Rackspace Cloud Servers"
|
||||
HOME_URL="http://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
|
||||
|
||||
### 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
|
||||
- **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
|
||||
|
||||
See docker example below.
|
||||
|
||||
## user-data Script
|
||||
|
||||
Simply set your user-data to a script where the first line is a shebang:
|
||||
|
||||
```
|
||||
#!/bin/bash
|
||||
|
||||
echo 'Hello, world!'
|
||||
```
|
||||
|
||||
## Examples
|
||||
|
||||
### Inject an SSH key, bootstrap etcd, and start fleet
|
||||
```
|
||||
#cloud-config
|
||||
|
||||
coreos:
|
||||
etcd:
|
||||
discovery_url: https://discovery.etcd.io/827c73219eeb2fa5530027c37bf18877

|
||||
|
||||
### Start a docker container on boot
|
||||
|
||||
```
|
||||
#cloud-config
|
||||
|
||||
coreos:
|
||||
units:

||||
WantedBy=local.target
|
||||
```
|
||||
|
||||
### Add a user
|
||||
|
||||
```
|
||||
#cloud-config
|
||||
|
||||
users:
|
||||
- name: elroy

||||
|
||||
### Inject configuration files
|
||||
|
||||
```
|

||||
metadata="region=us-west,type=ssd"
|
||||
```
|
||||
|
||||
### 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 \
|

#Debian Interfaces#
|
||||
**WARNING**: This option is EXPERIMENTAL and may change or be removed at any
|
||||
point.
|
||||
There is basic support for converting from a Debian network configuration to
|
||||
networkd unit files. The -convert-netconf=debian option is used to activate
|
||||
this feature.
|
||||
|
||||
#convert-netconf#

Default: ""

||||
Read the network config provided in cloud-drive and translate it from the
|

specified format into networkd unit files (requires the -from-configdrive
|
||||
flag). Currently only supports "debian" which provides support for a small
|
||||
subset of the [Debian network configuration]
|
||||
(https://wiki.debian.org/NetworkConfiguration). These options include:

||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|

separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.

2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,

|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the

|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

# 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
|
||||
```
