Functions

func LoadMetadata

func LoadMetadata(dir string) (*types.ClusterMetadata, error)

LoadMetadata loads the cluster metadata from an asset directory.

Types

type Cluster

type Cluster struct {
	FileList []*asset.File
}

Cluster uses the terraform executable to launch a cluster with the given terraform tfvar and generated templates.

func (*Cluster) Dependencies

func (c *Cluster) Dependencies() []asset.Asset

Dependencies returns the direct dependency for launching the cluster.

func (*Cluster) Files

func (c *Cluster) Files() []*asset.File

Files returns the FileList generated by the asset.

func (*Cluster) Generate

func (c *Cluster) Generate(parents asset.Parents) (err error)

Generate launches the cluster and generates the terraform state file on disk.

func (*Cluster) Load

func (c *Cluster) Load(f asset.FileFetcher) (found bool, err error)

Load returns error if the tfstate file is already on-disk, because we want to prevent user from accidentally re-launching the cluster.

func (*Cluster) Name

func (c *Cluster) Name() string

Name returns the human-friendly name of the asset.

type Metadata

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

Metadata contains information needed to destroy clusters.

func (*Metadata) Dependencies

func (m *Metadata) Dependencies() []asset.Asset

Dependencies returns the direct dependencies for the metadata asset.

func (*Metadata) Files

func (m *Metadata) Files() []*asset.File

Files returns the FileList generated by the asset.

func (*Metadata) Generate

func (m *Metadata) Generate(parents asset.Parents) (err error)

Generate generates the metadata asset.

func (*Metadata) Load

func (m *Metadata) Load(f asset.FileFetcher) (found bool, err error)

Load is a no-op, because we never want to load broken metadata from the disk.

func (*Metadata) Name

func (m *Metadata) Name() string

Name returns the human-friendly name of the asset.

type TerraformVariables

type TerraformVariables struct {
	FileList []*asset.File
}

TerraformVariables depends on InstallConfig and Ignition to generate the terrafor.tfvars.

func (*TerraformVariables) Dependencies

func (t *TerraformVariables) Dependencies() []asset.Asset

Dependencies returns the dependency of the TerraformVariable

func (*TerraformVariables) Files

func (t *TerraformVariables) Files() []*asset.File

Files returns the files generated by the asset.

func (*TerraformVariables) Generate

func (t *TerraformVariables) Generate(parents asset.Parents) error

Generate generates the terraform.tfvars file.

func (*TerraformVariables) Load

func (t *TerraformVariables) Load(f asset.FileFetcher) (found bool, err error)

Load reads the terraform.tfvars from disk.

func (*TerraformVariables) Name

func (t *TerraformVariables) Name() string

Name returns the human-friendly name of the asset.
