Maxime VISONNEAUandRobert Brennan 32c1150b28 config: new flags '--disallow-(config|annotation)-exemptions' (#636)
This change follows up #635 and lets end-users decide to disallow exemption rules defined as part of the config file or the controller annotations (whether none, any or both). The main use case here is to be able to prevent users with edit privileges over a controller to add a new exemption rule through an annotation which may obfuscate the actual policies we want to enforce.

# 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]
[homepage]: http://contributor-covenant.org

## Creating a new release
To create a new release, simply tag this repo with the new version.
### 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
For major and minor releases, don't forget to update the Helm chart at

# Check Settings
Each check can be assigned a `severity`. Only checks with a severity of `danger` or `warning` will be validated. The results of these validations are visible on the dashboard. In the case of the validating webhook, only failures with a severity of `danger` will result in a change being rejected.

If you'd like to create your own checks, you can use [JSON Schema](https://json-schema.org/). For example,

If you'd like to create your own checks, you can use [JSON Schema](https://json-schema.org/).
This is how built-in Polaris checks are defined as well - you can see all the built-in checks
in the [checks folder](https://github.com/FairwindsOps/polaris/tree/master/checks) for examples.
If you write a check that could be useful for others, feel free to open a PR to add it in!
## Basic Example
For example, to disallow images from quay.io:
```yaml
checks:
imageRegistry: warning
customChecks:
imageRegistry:
successMessage: Image comes from allowed registries
failureMessage: Image should not be from disallowed registry
category: Images
target: Container # target can be "Container" or "Pod"
category: Security
target: Container
schema:
'$schema': http://json-schema.org/draft-07/schema
type: object
@@ -21,6 +34,181 @@ customChecks:
pattern: ^quay.io
```
## Available Options
All custom checks should go under the `customChecks` field in your Polaris config, keyed by the
check ID. Note that you'll also have to set its severity in the `checks` section of your Polaris config.
* `successMessage` - the message to show when the check succeeds
* `failureMessage` - the message to show when the check fails
* `category` - one of `Security`, `Efficiency`, or `Reliability`
* `target` - specifies the type of resource to check. This can be:
* a group and kind, e.g. `apps/Deployment` or `networking.k8s.io/Ingress`
* `Controller`, to check _any_ resource that creates Pods (e.g. Deployments, CronJobs, StatefulSets), as well as naked Pods
* `PodSpec`, same as `Controller`, but the schema applies to the Pod spec rather than the top-level controller
* `Container` same as `Controller`, but the schema applies to all Container specs rather than the top-level controller
* `controllers` - if `target` is `Controller`, `Pod` or `Container`, you can use this to change which types of controllers are checked
* `controllers.include` - _only_ check these controllers
* `controllers.exclude` - check all controllers except these
* `containers` - if `target` is `Container`, you can use this to decide if `initContainers`, `containers`, or both should be checked
* `containers.exclude` - can be set to a list including `initContainer` or `container`
* `schema` - the JSON Schema to check against, as a YAML object
* `schemaString` - this JSON Schema to check against, as a YAML or JSON string. See [Templating](#templating) below
* Note: only _one_ of `schema` and `schemaString` can be specified.
* `additionalSchemas` - see [Multi-Resource Checks](#multi-resource-checks) below
* `additionalSchemaStrings` - see [Multi-Resource Checks](#multi-resource-checks) below
* Note: only _one_ of `additionalSchemas` and `additionalSchemaStrings` can be specified.
## Checking CPU and Memory
We extend JSON Schema with `resourceMinimum` and `resourceMaximum` fields to help compare memory and CPU resource
strings like `1000m` and `1G`. Here's an example check that memory and CPU falls within a certain range.
```yaml
customChecks:
resourceLimits:
containers:
exclude:
- initContainer
successMessage: Resource limits are within the required range
failureMessage: Resource limits should be within the required range
category: Resources
target: Container
schema:
'$schema': http://json-schema.org/draft-07/schema
type: object
required:
- resources
properties:

- cpu
properties:
memory:
type: string
resourceMinimum: 100M
resourceMaximum: 6G
cpu:
type: string
resourceMinimum: 100m
resourceMaximum: "2"
```
## Resource Presence
You can test for the presence of a resource in each Namespace. For example, to
ensure an AlertmanagerConfig is in every Namespace:
```yaml
successMessage: Namespace has monitoring configuration
failureMessage: Namespace should have monitoring configuration
category: Security
target: Namespace
schema: {}
additionalSchemas:
monitoring.coreos.com/AlertmanagerConfig: {}
```
## Templating
You can also utilize go templating in your JSON schema in order to match one field against another.
E.g. here is the built-in check to ensure that the `name` annotation matches the object's name:
```yaml
successMessage: Label app.kubernetes.io/name matches metadata.name
failureMessage: Label app.kubernetes.io/name must match metadata.name
target: Controller
schema:
'$schema': http://json-schema.org/draft-07/schema
type: object
properties:
metadata:
type: object
required: ["labels"]
properties:
labels:
type: object
required: ["app.kubernetes.io/name"]
properties:
app.kubernetes.io/name:
const: "{{ .metadata.name }}"
```
You can also use the full [Go template syntax](https://golang.org/pkg/text/template/), though
you may need to specify your schema as a string in order to use concepts like `range`. E.g.
this check ensures that at least one of the object's labels is present in `matchLabels`:
```yaml
schemaString: |
type: object
properties:
spec:
type: object
required: ["selector"]
properties:
selector:
type: object
required: ["matchLabels"]
properties:
matchLabels:
type: object
anyOf:
{{ range $key, $value := .metadata.labels }}
- properties:
"{{ $key }}":
type: string
const: {{ $value }}
required: ["{{ $key }}"]
{{ end }}
```
## Multi-Resource Checks
You can write checks that span multiple resources. This is helpful for ensuring e.g.
that every Deployment has a PDB or an HPA associated with it.
Here's the check to ensure that every Deployment has a PDB:
```yaml
successMessage: A PodDisruptionBudget is attached
failureMessage: Should have a PodDisruptionBudget
category: Reliability
target: Controller
controllers:
include:
- Deployment
schema:
'$schema': http://json-schema.org/draft-07/schema
type: object
properties:
metadata:
type: object
properties:
labels:

anyOf:
{{ range $key, $value := .metadata.labels }}
- properties:
"{{ $key }}":
type: string
const: {{ $value }}
required: ["{{ $key }}"]
{{ end }}
```

Schemas can also be specified as JSON strings instead of YAML, for easier copy/pasting:
