Types

type ApplyOpts

type ApplyOpts struct {
	Force       bool
	AutoApprove bool
}

ApplyOpts allow to specify additional parameter for apply operations

type DiffOpts

type DiffOpts struct {
	Summarize bool
}

DiffOpts allow to specify additional parameters for diff operations

type Differ

type Differ func(yaml string) (*string, error)

type ErrorMissingConfig

type ErrorMissingConfig struct {
	Verb string
}

func (ErrorMissingConfig) Error

func (e ErrorMissingConfig) Error() string

type ErrorNotFound

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

func (ErrorNotFound) Error

func (e ErrorNotFound) Error() string

type ErrorPrimitiveReached

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

ErrorPrimitiveReached occurs when walkJSON reaches the end of nested dicts without finding a valid Kubernetes manifest

func (ErrorPrimitiveReached) Error

func (e ErrorPrimitiveReached) Error() string

type FilteredErr

type FilteredErr []*regexp.Regexp

FilteredErr is a filtered Stderr. If one of the regular expressions match, the current input is discarded.

func (FilteredErr) Write

func (r FilteredErr) Write(p []byte) (n int, err error)

type Kubectl

type Kubectl struct {
	APIServer string
	// contains filtered or unexported fields
}

Kubectl uses the `kubectl` command to operate on a Kubernetes cluster

func (Kubectl) Apply

func (k Kubectl) Apply(yaml, namespace string, opts ApplyOpts) error

Apply applies the given yaml to the cluster

func (Kubectl) Diff

func (k Kubectl) Diff(yaml string) (*string, error)

Diff takes a desired state as yaml and returns the differences to the system in common diff format

func (Kubectl) Get

func (k Kubectl) Get(namespace, kind, name string) (map[string]interface{}, error)

Get retrieves an Kubernetes object from the API

func (Kubectl) SubsetDiff

func (k Kubectl) SubsetDiff(y string) (*string, error)

func (Kubectl) Version

func (k Kubectl) Version() (client, server semver.Version, err error)

Version returns the version of kubectl and the Kubernetes api server

type Kubernetes

type Kubernetes struct {
	Spec v1alpha1.Spec
	// contains filtered or unexported fields
}

Kubernetes bridges tanka to the Kubernetse orchestrator.

func New

func New(s v1alpha1.Spec) *Kubernetes

New creates a new Kubernetes

func (*Kubernetes) Apply

func (k *Kubernetes) Apply(state []Manifest, opts ApplyOpts) error

Apply receives a state object generated using `Reconcile()` and may apply it to the target system

func (*Kubernetes) Diff

func (k *Kubernetes) Diff(state []Manifest, opts DiffOpts) (*string, error)

Diff takes the desired state and returns the differences from the cluster

func (*Kubernetes) Fmt

func (k *Kubernetes) Fmt(state []Manifest) (string, error)

Fmt receives the state and reformats it to YAML Documents

func (*Kubernetes) Reconcile

func (k *Kubernetes) Reconcile(raw map[string]interface{}, objectspecs ...*regexp.Regexp) (state []Manifest, err error)

Reconcile receives the raw evaluated jsonnet as a marshaled json dict and shall return it reconciled as a state object of the target system

type Manifest

type Manifest map[string]interface{}

Manifest describes a single Kubernetes manifest

func (Manifest) Kind

func (m Manifest) Kind() string

func (Manifest) Name

func (m Manifest) Name() string

func (Manifest) Namespace

func (m Manifest) Namespace() string
