compiled to [Go
structs](https://github.com/istio/api/blob/master/operator/v1alpha1/operator.pb.go).
`IstioOperatorSpec` has pass-through fields to the Helm values.yaml API, but these are additionally validated through
a [schema](../operator/pkg/apis/istio/v1alpha1/values_types.proto).

This document is an overview of how the operator works from a user perspective. For more details about the design and
architecture and a code overview, see [ARCHITECTURE.md](../architecture/environments/operator.md).

## Introduction

The operator uses the [IstioOperator API](https://github.com/istio/api/blob/master/operator/v1alpha1/operator.proto), which has
three main components:

	"istio.io/istio/operator/pkg/util/clog"
	"istio.io/istio/operator/pkg/util/progress"
	"istio.io/istio/operator/pkg/verifier"
	pkgversion "istio.io/istio/operator/pkg/version"
	operatorVer "istio.io/istio/operator/version"
	"istio.io/istio/pkg/config/constants"
	"istio.io/istio/pkg/config/labels"
	"istio.io/istio/pkg/kube"
)

type InstallArgs struct {

					}
				}
				operator, matchType, value := toLowerString(condt[0]), toLowerString(condt[1]), toString(condt[2])
				if !strings.HasPrefix(matchType, "$") {
					return parsedPolicy, fmt.Errorf("Invalid according to Policy: Policy Condition failed: [%s, %s, %s]", operator, matchType, value)
				}

      override fun encodedValue(url: HttpUrl): String = url.encodedUsername

      override operator fun set(
        builder: HttpUrl.Builder,
        value: String,
      ) {
        builder.username(value)
      }

      override operator fun get(url: HttpUrl): String = url.username
    },

    PASSWORD {

    for (i in 0 until namesAndValues.size) {
      result += namesAndValues[i].length.toLong()
    }

    return result
  }
