Functions

func GetSetID

func GetSetID(bundleID, labelPrefix, labelSuffix string) string

GetSetID constructs a identifier from the provided args, bundleID "fleet-agent" is special

func Template

func Template(bundleID string, manifest *manifest.Manifest, options fleet.BundleDeploymentOptions) ([]runtime.Object, error)

Template runs helm template and returns the resources as a list of objects, without applying them.

Types

type DeployedBundle

type DeployedBundle struct {
	// BundleID is the bundle.Name
	BundleID string
	// ReleaseName is actually in the form "namespace/release name"
	ReleaseName string
	// KeepResources indicate if resources should be kept when deleting a GitRepo or Bundle
	KeepResources bool
}

type Helm

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

func NewHelm

func NewHelm(namespace, defaultNamespace, labelPrefix, labelSuffix string, getter genericclioptions.RESTClientGetter,
	serviceAccountCache corecontrollers.ServiceAccountCache, configmapCache corecontrollers.ConfigMapCache, secretCache corecontrollers.SecretCache) (*Helm, error)

func (*Helm) Delete

func (h *Helm) Delete(bundleID, releaseName string) error

Delete the release for the given bundleID. releaseName is a key in the format "namespace/name". If releaseName is empty, search for a matching release.

func (*Helm) Deploy

func (h *Helm) Deploy(bundleID string, manifest *manifest.Manifest, options fleet.BundleDeploymentOptions) (*Resources, error)

func (*Helm) EnsureInstalled

func (h *Helm) EnsureInstalled(bundleID, resourcesID string) (bool, error)

func (*Helm) ListDeployments

func (h *Helm) ListDeployments() ([]DeployedBundle, error)

ListDeployments returns a list of bundles by listing all helm releases via helm's storage driver (secrets)

func (*Helm) RemoveExternalChanges

func (h *Helm) RemoveExternalChanges(bd *fleet.BundleDeployment) error

RemoveExternalChanges does a helm rollback to remove changes made outside of fleet. It removes the helm history entry if the rollback fails.

func (*Helm) Resources

func (h *Helm) Resources(bundleID, resourcesID string) (*Resources, error)

Resources returns the resources from the helm release history

func (*Helm) ResourcesFromPreviousReleaseVersion

func (h *Helm) ResourcesFromPreviousReleaseVersion(bundleID, resourcesID string) (*Resources, error)

type Resources

type Resources struct {
	ID               string           `json:"id,omitempty"`
	DefaultNamespace string           `json:"defaultNamespace,omitempty"`
	Objects          []runtime.Object `json:"objects,omitempty"`
