Types

type CLI

type CLI struct {
	*pkgkubectl.CLI
	Flags latest.KubectlFlags

	ForceDeploy bool
	// contains filtered or unexported fields
}

CLI holds parameters to run kubectl.

func (*CLI) Apply

func (c *CLI) Apply(ctx context.Context, out io.Writer, manifests ManifestList) error

Apply runs `kubectl apply` on a list of manifests.

func (*CLI) Delete

func (c *CLI) Delete(ctx context.Context, out io.Writer, manifests ManifestList) error

Delete runs `kubectl delete` on a list of manifests.

func (*CLI) ReadManifests

func (c *CLI) ReadManifests(ctx context.Context, manifests []string) (ManifestList, error)

ReadManifests reads a list of manifests in yaml format.

type FieldVisitor

type FieldVisitor interface {
	// Visit is called for each transformable key contained in the object and may apply transformations/aggregations on it.
	// It should return true to allow recursive traversal or false when the entry was transformed.
	Visit(object map[string]interface{}, key string, value interface{}) bool
}

FieldVisitor represents the aggregation/transformation that should be performed on each traversed field.

type ManifestList

type ManifestList [][]byte

ManifestList is a list of yaml manifests.

func (*ManifestList) Append

func (l *ManifestList) Append(buf []byte)

Append appends the yaml manifests defined in the given buffer. `buf` can contain concatenated manifests without `---` separators because `kubectl create --dry-run -oyaml` produces such output.

func (*ManifestList) CollectNamespaces

func (l *ManifestList) CollectNamespaces() ([]string, error)

CollectNamespaces returns all the namespaces in the manifests.

func (*ManifestList) Diff

func (l *ManifestList) Diff(latest ManifestList) ManifestList

Diff computes the list of manifests that have changed.

func (*ManifestList) GetImages

func (l *ManifestList) GetImages() ([]build.Artifact, error)

GetImages gathers a map of base image names to the image with its tag

func (*ManifestList) Reader

func (l *ManifestList) Reader() io.Reader

Reader returns a reader on the raw yaml descriptors.

func (*ManifestList) ReplaceImages

func (l *ManifestList) ReplaceImages(builds []build.Artifact) (ManifestList, error)

ReplaceImages replaces image names in a list of manifests.

func (*ManifestList) SetLabels

func (l *ManifestList) SetLabels(labels map[string]string) (ManifestList, error)

SetLabels add labels to a list of Kubernetes manifests.

func (*ManifestList) String

func (l *ManifestList) String() string

func (*ManifestList) Visit

func (l *ManifestList) Visit(visitor FieldVisitor) (ManifestList, error)

Visit recursively visits all transformable object fields within the manifests and lets the visitor apply transformations/aggregations on them.
