Types

type FilesBuilder

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

FilesBuilder is a database of files to be created in nodes. It also implements cke.Commander.

func NewFilesBuilder

func NewFilesBuilder(nodes []*cke.Node) *FilesBuilder

NewFilesBuilder creates a new FilesBuilder.

func (*FilesBuilder) AddFile

func (c *FilesBuilder) AddFile(ctx context.Context, name string, f func(context.Context, *cke.Node) ([]byte, error)) error

AddFile adds a file to the builder. The contents of the file will be generated by f.

func (*FilesBuilder) AddKeyPair

func (c *FilesBuilder) AddKeyPair(ctx context.Context, name string,
	f func(context.Context, *cke.Node) (cert, key []byte, err error)) error

AddKeyPair adds a certificate and private key pair to the builder. The certificate data and private key data will be generated by f.

func (*FilesBuilder) Command

func (c *FilesBuilder) Command() cke.Command

Command implements cke.Commander

func (*FilesBuilder) Run

func (c *FilesBuilder) Run(ctx context.Context, inf cke.Infrastructure) error

Run implements cke.Commander.

type RunOption

type RunOption func(c *runContainerCommand)

RunOption is a functional option for RunContainerCommand

func WithExtra

func WithExtra(params cke.ServiceParams) RunOption

WithExtra returns RunOption to set extra ServiceParams.

func WithOpts

func WithOpts(opts []string) RunOption

WithOpts returns RunOption to set container engine options.

func WithOptsMap

func WithOptsMap(optsMap map[string][]string) RunOption

WithOptsMap returns RunOption to set container engine options for each node.

func WithParams

func WithParams(params cke.ServiceParams) RunOption

WithParams returns RunOption to set ServiceParams.

func WithParamsMap

func WithParamsMap(paramsMap map[string]cke.ServiceParams) RunOption

WithParamsMap returns RunOption to set ServiceParams for each node.

func WithRestart

func WithRestart() RunOption

WithRestart returns RunOption to restart a container.
