Types

type Config

type Config struct {
	Namespace       string      `yaml:",omitempty"`
	TillerNamespace string      `yaml:",omitempty"`
	Local           bool        `yaml:",omitempty"`
	Context         string      `yaml:",omitempty"`
	KubeConfig      interface{} `yaml:",omitempty"` // it's just a kubeconfig, we don't need to parse it
}

Config represents K8s/Helm plugin configuration

type Plugin

type Plugin struct {
	// contains filtered or unexported fields
}

Plugin uses Helm for deployment of apps on kubernetes

func NewPlugin

func NewPlugin(cfg config.Helm) *Plugin

NewPlugin creates a new helm plugin

func (*Plugin) Cleanup

func (plugin *Plugin) Cleanup() error

Cleanup implements cleanup phase for the Helm plugin. It closes all created and cached Tiller tunnels.

func (*Plugin) Create

func (plugin *Plugin) Create(cluster *lang.Cluster, deployName string, params util.NestedParameterMap, eventLog *event.Log) error

Create implements creation of a new component instance in the cloud by deploying a Helm chart

func (*Plugin) Destroy

func (plugin *Plugin) Destroy(cluster *lang.Cluster, deployName string, params util.NestedParameterMap, eventLog *event.Log) error

Destroy implements destruction of an existing component instance in the cloud by running "helm delete" on the corresponding helm chart

func (*Plugin) Endpoints

func (plugin *Plugin) Endpoints(cluster *lang.Cluster, deployName string, params util.NestedParameterMap, eventLog *event.Log) (map[string]string, error)

Endpoints returns map from port type to url for all services of the current chart TODO: reduce cyclomatic complexity

func (*Plugin) GetSupportedCodeTypes

func (plugin *Plugin) GetSupportedCodeTypes() []string

GetSupportedCodeTypes returns all code types for which this plugin is registered to

func (*Plugin) Process

func (plugin *Plugin) Process(policy *lang.Policy, resolution *resolve.PolicyResolution, externalData *external.Data, eventLog *event.Log) error

Process is a action which gets called only once. It manages all Istio rules across all clusters, making sure they are up to date by creating/deleting/updating rules if/as needed TODO: reduce cyclomatic complexity

func (*Plugin) Update

func (plugin *Plugin) Update(cluster *lang.Cluster, deployName string, params util.NestedParameterMap, eventLog *event.Log) error

Update implements update of an existing component instance in the cloud by updating parameters of a helm chart
