# Contributing guidelines
|
||||
|
||||
## How to become a contributor and submit your own code
|
||||
|
||||
### Contributor License Agreements
|
||||
|
||||
We'd love to accept your patches! Before we can take them, we have to jump a couple of legal hurdles.
|
||||
|
||||
Please fill out either the individual or corporate Contributor License Agreement (CLA).
|
||||
|
||||
* If you are an individual writing original source code and you're sure you own the intellectual property, then you'll need to sign an [individual CLA](https://identity.linuxfoundation.org/node/285/node/285/individual-signup).
|
||||
* If you work for a company that wants to allow you to contribute your work, then you'll need to sign a [corporate CLA](https://identity.linuxfoundation.org/node/285/organization-signup).
|
||||
|
||||
Follow either of the two links above to access the appropriate CLA and instructions for how to sign and return it. Once we receive it, we'll be able to accept your pull requests.
|
||||
|
||||
### Contributing A Patch
|
||||
|
||||
1. Submit an issue describing your proposed change to the repo in question.
|
||||
1. The [repo owners](OWNERS) will respond to your issue promptly.
|
||||
1. If your proposed change is accepted, and you haven't already done so, sign a Contributor License Agreement (see details above).
|
||||
1. Fork the desired repo, develop and test your code changes.
|
||||
1. Submit a pull request.
|
||||
|
||||
### Adding dependencies
|
||||
|
||||
If your patch depends on new packages, add that package with [`godep`](https://github.com/tools/godep). Follow the [instructions to add a dependency](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/development.md#godep-and-dependency-management).

||||
form, that is based on (or derived from) the Work and for which the
|
||||

|
||||
of this License, Derivative Works shall not include works that remain

||||
copyright license to reproduce, prepare Derivative Works of,

||||
(except as stated in this section) patent license to make, have made,

|
||||
by such Contributor that are necessarily infringed by their

|
||||
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
|
||||

|
||||
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.

||||
|
||||

# Custom Metrics Adpater Server Boilerplate
|
||||
|
||||
## Purpose
|
||||
|
||||
This repository contains boilerplate code for setting up an implementation
|
||||
of the custom metrics API (https://github.com/kubernetes/metrics).
|
||||
|
||||
It includes the necessary boilerplate for setting up an implementation
|
||||
(generic API server setup, registration of resources, etc), plus a sample
|
||||
implementation backed by fake data.
|
||||
|
||||
## How to use this repository
|
||||
|
||||
In order to use this repository, you should vendor this repository at
|
||||
`github.com/directxman12/custom-metrics-boilerplate`, and implement the
|
||||
`"github.com/directxman12/custom-metrics-boilerplate/pkg/provider".CustomMetricsProvider`
|
||||
interface. You can then pass this to the main setup functions.
|
||||
|
||||
The `pkg/cmd` package contains the building blocks of the actual API
|
||||
server setup. You'll most likely want to wrap the existing options and
|
||||
flags setup to add your own flags for configuring your provider.
|
||||
|
||||
A sample implementation of this can be found in the file `sample-main.go`
|
||||
and `pkg/sample-cmd` directory. You'll want to have the equivalent files
|
||||
in your project.
|
||||
|
||||
### A note on Dependencies
|
||||
|
||||
You'll need to `glide install` dependencies before you can use this
|
||||
project.
|
||||
|
||||
## Compatibility

## Kubernetes Community Code of Conduct
|
||||
|
||||
### Contributor Code of Conduct
|
||||
|
||||
As contributors and maintainers of this project, and in the interest of fostering
|
||||
an open and welcoming community, we pledge to respect all people who contribute
|
||||
through reporting issues, posting feature requests, updating documentation,
|
||||
submitting pull requests or patches, and other activities.
|
||||
|
||||
We are committed to making participation in this project a harassment-free experience for
|
||||
everyone, regardless of level of experience, gender, gender identity and expression,
|
||||
sexual orientation, disability, personal appearance, body size, race, ethnicity, age,
|
||||
religion, or nationality.
|
||||
|
||||
Examples of unacceptable behavior by participants include:
|
||||
|
||||
* The use of sexualized language or imagery
|
||||
* Personal attacks
|
||||
* Trolling or insulting/derogatory comments
|
||||
* Public or private harassment
|
||||
* Publishing other's private information, such as physical or electronic addresses,
|
||||
without explicit permission
|
||||
* Other unethical or unprofessional conduct.
|
||||
|
||||
Project maintainers have the right and responsibility to remove, edit, or reject
|
||||
comments, commits, code, wiki edits, issues, and other contributions that are not
|
||||
aligned to this Code of Conduct. By adopting this Code of Conduct, project maintainers
|
||||
commit themselves to fairly and consistently applying these principles to every aspect
|
||||
of managing this project. Project maintainers who do not follow or enforce the Code of
|
||||
Conduct may be permanently removed from the project team.
|
||||
|
||||
This code of conduct applies both within project spaces and in public spaces
|
||||
when an individual is representing the project or its community.
|
||||
|
||||
Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting a Kubernetes maintainer, Sarah Novotny <sarahnovotny@google.com>, and/or Dan Kohn <dan@linuxfoundation.org>.
|
||||
|
||||
This Code of Conduct is adapted from the Contributor Covenant
|
||||
(http://contributor-covenant.org), version 1.2.0, available at
|
||||
http://contributor-covenant.org/version/1/2/0/
|
||||
|
||||
### Kubernetes Events Code of Conduct
|
||||
|
||||
Kubernetes events are working conferences intended for professional networking and collaboration in the
|
||||
Kubernetes community. Attendees are expected to behave according to professional standards and in accordance
|
||||
with their employer's policies on appropriate workplace behavior.
|
||||
|
||||
While at Kubernetes events or related social networking opportunities, attendees should not engage in
|
||||
discriminatory or offensive speech or actions regarding gender, sexuality, race, or religion. Speakers should
|
||||
be especially aware of these concerns.
|
||||
|
||||
The Kubernetes team does not condone any statements by speakers contrary to these standards. The Kubernetes
|
||||
team reserves the right to deny entrance and/or eject from an event (without refund) any individual found to
|
||||
be engaging in discriminatory or offensive speech or actions.
|
||||
|
||||
Please bring any concerns to to the immediate attention of Kubernetes event staff
