Overview

Package mesh_install exposes functions for applying resources to a Kubernetes cluster. Its exposed functions receive a K8sClient for communicating with the cluster.

Types

type Installer

type Installer struct {
	*gmapi.CLI // Grey Matter CLI
	K8sClient  *client.Client

	// Container for THE mesh (on the way to an experimental 1:1 operator:mesh paradigm)
	// Contains the default after load
	Mesh *v1alpha1.Mesh

	// Container for all K8s and GM CUE cue.Values
	OperatorCUE *cuemodule.OperatorCUE

	// Root on disk of the operator CUE. Used for reloading the default configs on teardown
	CueRoot string

	// Operator config loadable from CUE
	Config cuemodule.Config

	// Select defaults that may be directly overridden from Go
	Defaults cuemodule.Defaults

	// Sync configuration with access to a callback for updating on git repo changes
	Sync *sync.Sync
	// contains filtered or unexported fields
}

Installer stores a map of version.Version and a distinct version.Sidecar for each mesh.

func New

func New(c *client.Client, operatorCUE *cuemodule.OperatorCUE, initialMesh *v1alpha1.Mesh, cueRoot string, gmcli *gmapi.CLI, cfssl *cfsslsrv.CFSSLServer, sync *sync.Sync) (*Installer, error)

New returns a new *Installer instance for installing Grey Matter components and dependencies.

func (*Installer) ApplyMesh

func (i *Installer) ApplyMesh(prev, mesh *v1alpha1.Mesh)

ApplyMesh installs and updates Grey Matter core components and dependencies for a single mesh.

func (*Installer) RemoveMesh

func (i *Installer) RemoveMesh(mesh *v1alpha1.Mesh)

RemoveMesh removes all references to a deleted Mesh custom resource. It does not uninstall core components and dependencies, since that is handled by the apiserver when the Mesh custom resource is deleted.

func (*Installer) Start

func (i *Installer) Start(ctx context.Context) error

Start initializes resources and configurations after controller-manager has launched. It implements the controller-runtime Runnable interface.
