## Making changes

## Step 1. Make changes in charts and values.yaml in `manifests` directory

Be sure to provide sufficient documentation and example usage in values.yaml.
If the chart has a `values.schema.json`, that should be updated as well.

## Step 2. Update the istioctl/Operator values

If you are modifying the `gateway` chart, you can stop here.

lint-sass:
	@${FINDFILES} -name '*.scss' -print0 | ${XARGS} sass-lint -c common/config/sass-lint.yml --verbose

lint-typescript:
	@${FINDFILES} -name '*.ts' -print0 | ${XARGS} tslint -c common/config/tslint.json

lint-licenses:
	@if test -d licenses; then license-lint --config common/config/license-lint.yml; fi

```console
$ gcloud logging read "resource.type=k8s_node AND jsonPayload.SYSLOG_IDENTIFIER=kubelet AND jsonPayload.MESSAGE:cmdAdd" --limit 10 --format json
```

## Other Reference

The framework for this implementation of the CNI plugin is based on the
[containernetworking sample plugin](https://github.com/containernetworking/plugins/tree/main/plugins/sample)

We can exploit this to make a more efficient protocol, which is critical to achieve our resource footprint goals.

For example, configuring Istio mTLS in Envoy takes roughly 50 lines of JSON (it is in Protobuf, of course, but still relevant).
Because Ztunnel can have Istio semantics baked in, we do not need to encode all this information on the wire.

#### Calico

For Calico, you must also modify the settings to allow source spoofing:

- if deployed by operator,  `kubectl patch felixconfigurations default --type='json' -p='[{"op": "add", "path": "/spec/workloadSourceSpoofing", "value": "Any"}]'`

// Package-wide variables from generator "generated".
option go_package = "k8s.io/apimachinery/pkg/api/resource";

// Quantity is a fixed-point representation of a number.
// It provides convenient marshaling/unmarshaling in JSON and YAML,
// in addition to String() and AsInt64() accessors.
//
// The serialization format is:
//
// ```
// <quantity>        ::= <signedNumber><suffix>
//

  // defaultMode is optional: mode bits used to set permissions on created files by default.
  // Must be an octal value between 0000 and 0777 or a decimal value between 0 and 511.
  // YAML accepts both octal and decimal values, JSON requires decimal values for mode bits.
  // Defaults to 0644.
  // Directories within the path are not affected by this setting.
  // This might be in conflict with other options that affect the file
