Types ¶

type Context ¶

type Context struct {
	Chroot            string
	EnableTools       bool
	SnapshotPath      string
	SnapshotRoot      string
	SnapshotExclusive bool
	// contains filtered or unexported fields
}

Concrete merged set of configuration switches that act as an execution context when calling internal discovery methods

func FromEnv ¶

func FromEnv() *Context

FromEnv returns an Option that has been populated from the environs or default options values

func New ¶

func New(opts ...*option.Option) *Context

New returns a Context struct pointer that has had various options set on it

func (*Context) Do ¶

func (ctx *Context) Do(fn func() error) error

Do wraps a Setup/Teardown pair around the given function

func (*Context) Setup ¶

func (ctx *Context) Setup() error

Setup prepares the extra optional data a Context may use. `Context`s are ready to use once returned by `New`. Optional features, like snapshot unpacking, may require extra steps. Run `Setup` to perform them. You should call `Setup` just once. It is safe to call `Setup` if you don't make use of optional extra features - `Setup` will do nothing.

func (*Context) Teardown ¶

func (ctx *Context) Teardown() error

Teardown releases any resource acquired by Setup. You should always call `Teardown` if you called `Setup` to free any resources acquired by `Setup`. Check `Do` for more automated management.

func (*Context) Warn ¶

func (ctx *Context) Warn(msg string, args ...interface{})
