# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
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, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at opensource@fairwinds.com. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at [http://contributor-covenant.org/version/1/4][version]

This means that any checks with a severity of `warning` will still pass webhook validation,
and the only evidence of that warning will either be in the Polaris dashboard or the
Polaris webhook logs. This will change in a future version of Kubernetes.
## Mutating Webhook
By default, the Admission Controller is just pass/fail, but
Polaris can also operate as a mutating webhook for many of the issues it checks for.
This means Polaris will remediate the issue it finds, rather than rejecting
the deployment.
To enable the mutating webhook, add `--set webhook.mutate=true` to your
Helm instlallation command.
By default, the only mutation enabled is `pullPolicyNotAlways`. If you'd like to
enable other mutations, you can set the `webhook.mutations` flag.

## Creating a new release
To create a new release, simply tag this repo with the new version.
For major and minor releases, don't forget to update the Helm chart at
https://github.com/FairwindsOps/charts
### Patch releases
Patch releases only need to change this repo. The Helm chart and deploy scripts
will automatically pull in the latest changes.
If the release involves changes to anything in the `deploy/` folder (e.g. new RBAC permissions),
it needs to be a minor or major release in order to prevent breaking the Helm chart.
1. Create a PR for this repo
1. Bump the version number in:
1. main.go
2. README.md
2. Update CHANGELOG.md
3. Merge your PR
2. Tag the latest branch for this repo
1. Pull the latest commit for the `master` branch (which you just merged in your PR)
2. Run `git tag $VERSION && git push --tags`
3. Make sure CircleCI runs successfully for the new tag - this will push images to quay.io and create a release in GitHub
1. If CircleCI fails, check with Codeowners ASAP
### Minor/Major releases
Minor and major releases need to change both this repository and the
[Helm chart repo](https://github.com/FairwindsOps/charts/).
The steps are:
1. Modify the [Helm chart](https://github.com/FairwindsOps/charts/stable/polaris)
1. Clone the helm charts repo
1. `git clone https://github.com/FairwindsOps/charts`
2. `git checkout -b yourname/update-polaris`
1. Bump the version number in `stable/polaris/Chart.yaml`
2. Make any necessary changes to the chart to support the new version of Polaris (e.g. new RBAC permissions)
3. **Don't merge yet!**
2. Create a PR for this repo
1. Create a new branch named `yourname/update-version`
2. Bump the version number in:
1. main.go
2. README.md
3. Regenerate the deployment files. Assuming you've cloned the charts repo to `~/git/charts`:
1. `CHARTS_DIR=~/git/charts ./scripts/generate-deployment-files.sh`
4. Update CHANGELOG.md
5. Merge your PR
3. Tag the latest branch for this repo
1. Pull the latest for the `master` branch
2. Run `git tag $VERSION && git push --tags`
3. Make sure CircleCI runs successfully for the new tag - this will push images to quay.io and create a release in GitHub
1. If CircleCI fails, check with Codeowners ASAP
4. Create and merge a PR for your changes to the Helm chart

## Checking Infrastructure as Code files
You can audit Kubernetes YAML files by running:
```bash
polaris audit --audit-path ./deploy/ --format=pretty
```
This will print out any issues Polaris finds in your manifests.
Polaris can only check raw YAML manifests. If you'd like to check a Helm template,
you can run `helm template` to generate a manifest that Polaris can check.
## Fixing Issues
Polaris can automatically fix many of the issues it finds. For example, you can run
```bash
polaris fix --files-path ./deploy/ --checks=all
```
to fix any issues inside the `deploy` directory. Polaris may leave
comments next to some changes (e.g. liveness and readiness probes) prompting
the user to set them to something more appropriate given the context of their
application.
Note that not all issues can be automatically fixed.
Currently only raw YAML manifests can be mutated. Helm charts etc.
still need to be changed manually.
