Types

type ExistingResources 

type ExistingResources struct {
	BackendPools       []n.ApplicationGatewayBackendAddressPool
	Certificates       []n.ApplicationGatewaySslCertificate
	RoutingRules       []n.ApplicationGatewayRequestRoutingRule
	Listeners          []n.ApplicationGatewayHTTPListener
	URLPathMaps        []n.ApplicationGatewayURLPathMap
	HTTPSettings       []n.ApplicationGatewayBackendHTTPSettings
	Ports              []n.ApplicationGatewayFrontendPort
	Probes             []n.ApplicationGatewayProbe
	Redirects          []n.ApplicationGatewayRedirectConfiguration
	ProhibitedTargets  []*ptv1.AzureIngressProhibitedTarget
	DefaultBackendPool *n.ApplicationGatewayBackendAddressPool
	// contains filtered or unexported fields
}

ExistingResources is used in brownfield deployments and holds a copy of the existing App Gateway config, based on which AGIC will determine what should be retained and what config should be discarded or overwritten.

func NewExistingResources 

func NewExistingResources(appGw n.ApplicationGateway, prohibitedTargets []*ptv1.AzureIngressProhibitedTarget, defaultPool *n.ApplicationGatewayBackendAddressPool) ExistingResources

NewExistingResources creates a new ExistingResources struct.

func (ExistingResources) GetBlacklistedHTTPSettings 

func (er ExistingResources) GetBlacklistedHTTPSettings() ([]n.ApplicationGatewayBackendHTTPSettings, []n.ApplicationGatewayBackendHTTPSettings)

GetBlacklistedHTTPSettings filters the given list of routing pathMaps to the list pathMaps that AGIC is allowed to manage. HTTP Setting is blacklisted when it is associated with a Routing Rule that is blacklisted.

func (ExistingResources) GetBlacklistedListeners 

func (er ExistingResources) GetBlacklistedListeners() ([]n.ApplicationGatewayHTTPListener, []n.ApplicationGatewayHTTPListener)

GetBlacklistedListeners filters the given list of health probes to the list Probes that AGIC is allowed to manage.

func (ExistingResources) GetBlacklistedPathMaps 

func (er ExistingResources) GetBlacklistedPathMaps() ([]n.ApplicationGatewayURLPathMap, []n.ApplicationGatewayURLPathMap)

GetBlacklistedPathMaps filters the given list of routing pathMaps to the list pathMaps that AGIC is allowed to manage.

func (ExistingResources) GetBlacklistedPools 

func (er ExistingResources) GetBlacklistedPools() ([]n.ApplicationGatewayBackendAddressPool, []n.ApplicationGatewayBackendAddressPool)

GetBlacklistedPools removes the managed pools from the given list of pools; resulting in a list of pools not managed by AGIC.

func (ExistingResources) GetBlacklistedProbes 

func (er ExistingResources) GetBlacklistedProbes() ([]n.ApplicationGatewayProbe, []n.ApplicationGatewayProbe)

GetBlacklistedProbes filters the given list of health probes to the list Probes that AGIC is allowed to manage.

func (ExistingResources) GetBlacklistedRedirects 

func (er ExistingResources) GetBlacklistedRedirects() ([]n.ApplicationGatewayRedirectConfiguration, []n.ApplicationGatewayRedirectConfiguration)

GetBlacklistedRedirects removes the managed redirects from the given list of redirects; resulting in a list of redirects not managed by AGIC.

func (ExistingResources) GetBlacklistedRoutingRules 

func (er ExistingResources) GetBlacklistedRoutingRules() ([]n.ApplicationGatewayRequestRoutingRule, []n.ApplicationGatewayRequestRoutingRule)

GetBlacklistedRoutingRules filters the given list of routing rules to the list rules that AGIC is allowed to manage.

type Logger 

type Logger interface {
	// Info is the a function allowing us to log messages.
	Info(args ...interface{})
}

Logger is an abstraction over a logging facility.

type Target 

type Target struct {
	Hostname string     `json:"Hostname,omitempty"`
	Path     TargetPath `json:"Path,omitempty"`
}

Target uniquely identifies a subset of App Gateway configuration, which AGIC will manage or be prohibited from managing.

func (Target) IsBlacklisted 

func (t Target) IsBlacklisted(blacklist TargetBlacklist) bool

IsBlacklisted figures out whether a given Target objects in a list of blacklisted targets.

type TargetBlacklist
