# 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

Polaris is an open source policy engine for Kubernetes that validates and remediates resource configuration. It includes 30+ built in configuration policies, as well as the ability to build custom policies with JSON Schema. When run on the command line or as a mutating webhook, Polaris can automatically remediate issues based on policy criteria.
Fairwinds' Polaris keeps your clusters sailing smoothly. It runs a variety of checks to ensure that
Kubernetes pods and controllers are configured using best practices, helping you avoid
problems in the future. Polaris can be run in a few different modes:
Polaris can be run in three different modes:
* As a [dashboard](https://polaris.docs.fairwinds.com/dashboard) - Validate Kubernetes resources against policy-as-code.
* As an [admission controller](https://polaris.docs.fairwinds.com/admission-controller) - Automatically reject or modify workloads that don't adhere to your organization's policies.
* As a [command-line tool](https://polaris.docs.fairwinds.com/infrastructure-as-code) - Incorporate policy-as-code into the CI/CD process to test local YAML files.
* As a [dashboard](https://polaris.docs.fairwinds.com/dashboard), so you can audit what's running inside your cluster.
* As an [admission controller](https://polaris.docs.fairwinds.com/admission-controller), so you can automatically reject workloads that don't adhere to your organization's policies.
* As a [command-line tool](https://polaris.docs.fairwinds.com/infrastructure-as-code), so you can test local YAML files, e.g. as part of a CI/CD process.

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 installation command.
The following default checks currently have mutation support enabled:
* `hostPIDSet`
* `hostNetworkSet`
* `hostIPCSet`
* `priorityClassNotSet`
* `hostPortSet`
* `pullPolicyNotAlways`
* `deploymentMissingReplicas`
* `dangerousCapabilities`
* `cpuLimitsMissing`
* `memoryLimitsMissing`
* `livenessProbeMissing`
* `memoryRequestsMissing`
* `cpuRequestsMissing`
* `runAsPrivileged`
* `readinessProbeMissing`
* `privilegeEscalationAllowed`
* `notReadOnlyRootFilesystem`
* `insecureCapabilities`
* `runAsRootAllowed`
If you'd like to
enable other mutations, you can set the `webhook.mutations` flag.

## Background
### Liveness and Readiness Probes
Readiness and liveness probes can help maintain the health of applications running inside Kubernetes. By default, Kubernetes only knows whether or not a process is running, not if it's healthy. Properly configured readiness and liveness probes will also be able to ensure the health of an application.
Readiness probes are designed to ensure that an application has reached a "ready" state. In many cases there is a period of time between when a webserver process starts and when it is ready to receive traffic. A readiness probe can ensure the traffic is not sent to a pod until it is actually ready to receive traffic.
Liveness probes are designed to ensure that an application stays in a healthy state. When a liveness probe fails, the pod will be restarted.
### Image Pull Policy
Docker's `latest` tag is applied by default to images where a tag hasn't been specified. Not specifying a specific version of an image can lead to a wide variety of problems. The underlying image could include unexpected breaking changes that break your application whenever the latest image is pulled. Reusing the same tag for multiple versions of an image can lead to different nodes in the same cluster having different versions of an image, even if the tag is identical.
Related to that, relying on cached versions of a Docker image can become a security vulnerability. By default, an image will be pulled if it isn't already cached on the node attempting to run it. This can result in variations in images that are running per node, or potentially provide a way to gain access to an image without having direct access to the ImagePullSecret. With that in mind, it's often better to ensure the a pod has `pullPolicy: Always` specified, so images are always pulled directly from their source.
### Topology Spread Constraints
By default, the Kubernetes scheduler uses a bin-packing algorithm to fit as many pods as possible into a cluster. The scheduler prefers a more evenly distributed general node load to app replicas precisely spread across nodes. Therefore, by default, multi-replica is not guaranteed to be spread across multiple availability zones. Kubernetes provides topologySpreadConstraint configuration in order to better ensure pod spread across multiple AZs and/or Hosts.
Example of a topologySpreadConstraint spreading across zones:
```
apiVersion: apps/v1
kind: Deployment
metadata:
name: demo-basic-demo
spec:
selector:
matchLabels:
app.kubernetes.io/name: basic-demo
app.kubernetes.io/instance: demo
template:
metadata:
labels:
app.kubernetes.io/name: basic-demo
app.kubernetes.io/instance: demo
spec:
topologySpreadConstraints:

topologyKey: "topology.kubernetes.io/zone"
whenUnsatisfiable: ScheduleAnyway
```

`security.hostPortSet` | `warning` | Fails when `hostPort` attribute is configured.
## Background
Securing workloads in Kubernetes is an important part of overall cluster security. The overall goal should be to ensure that containers are running with as minimal privileges as possible. This includes avoiding privilege escalation, not running containers with a root user, not giving excessive access to the host network, and using read only file systems wherever possible.
A pod running with the `hostNetwork` attribute enabled will have access to the loopback device, services listening on localhost, and could be used to snoop on network activity of other pods on the same node. There are certain examples where setting `hostNetwork` to true is required, such as deploying a networking plugin like Flannel.
Setting the `hostPort` attribute on a container will ensure that it is accessible on that specific port on each node it is deployed to. Unfortunately when this is specified, it limits where a pod can actually be scheduled in a cluster.
Much of this configuration can be found in the `securityContext` attribute for both Kubernetes pods and containers. Where configuration is available at both a pod and container level, Polaris validates both.

# Infrastructure as Code
Polaris can be used on the command line to audit local Kubernetes manifests stored in YAML files.
This is particularly helpful for running Polaris against your infrastructure-as-code as part of a
CI/CD pipeline. Use the available [command line flags](#running-in-a-ci-pipeline)
to cause CI/CD to fail if your Polaris score drops below a certain threshold, or if any danger-level issues arise.
## Install the CLI
To run Polaris against your YAML manifests, e.g. as part of a Continuous Integration process,
you'll need to install the CLI.
Binary releases can be downloaded from the [releases page](https://github.com/fairwindsops/polaris/releases)
or can be installed with [Homebrew](https://brew.sh/):
```bash
brew tap FairwindsOps/tap
brew install FairwindsOps/tap/polaris
polaris version
```
## Running in a CI pipeline
You can tell the CLI to set an exit code if it detects certain issues with your
YAML files.
For example, to fail if polaris detects *any* danger-level issues, or if the score drops below 90%:
```bash
polaris audit --audit-path ./deploy/ \
--set-exit-code-on-danger \
--set-exit-code-below-score 90

This is indicative of the greater goal of Polaris, not just to encourage better
configuration through dashboard visibility, but to actually enforce it with this webhook.</p> <p>Note that Polaris will not alter your workloads, only block workloads that don't conform to the configured policies.</p> <h2 id="installation"><a href="#installation" class="header-anchor">#</a> Installation</h2> <p>A valid TLS certificate is required for the Polaris Validating Webhook.
