func (c *Config) SetHomeDir(home string)

SetHomeDir is a test function that allows tests to use an alternate Porter home directory.

func (*Config) SetPorterPath

func (c *Config) SetPorterPath(path string)

SetPorterPath is a test function that allows tests to use an alternate Porter binary location.

type Data

type Data struct {

	// Available values are: docker, kubernetes.
	RuntimeDriver string `mapstructure:"runtime-driver"`

	// upon which it is running so that it can do things like build and run containers.
	// It's a security risk.
	AllowDockerHostAccess bool `mapstructure:"allow-docker-host-access"`

	// DefaultStoragePlugin is the storage plugin to use when no named storage is specified.
	DefaultStoragePlugin string `mapstructure:"default-storage-plugin"`

	// DefaultStorage to use when a named storage is not specified by a flag.
	DefaultStorage string `mapstructure:"default-storage"`

	// ExperimentalFlags is a list of enabled experimental.FeatureFlags.
	// Use Config.IsFeatureEnabled instead of parsing directly.
	ExperimentalFlags []string `mapstructure:"experimental"`

	// StoragePlugins defined in the configuration file.
	StoragePlugins []StoragePlugin `mapstructure:"storage"`

	// DefaultSecretsPlugin is the plugin to use when no plugin is specified.
	DefaultSecretsPlugin string `mapstructure:"default-secrets-plugin"`

	// DefaultSecrets to use when one is not specified by a flag.
	DefaultSecrets string `mapstructure:"default-secrets"`

	// Namespace is the default namespace for commands that do not override it with a flag.
