type Environment

type Environment map[string]string

Environment is a set of environment variables to be set in the step.

type Finalize

type Finalize struct {
	From string `yaml:"from,omitempty"`
	To   string `yaml:"to,omitempty"`
}

Finalize is a set of COPY instructions to finalize the build.

type Install

type Install []string

Install is a list of Alpine package names to install.

type Instruction

type Instruction string

Instruction is a single shell command.

func (Instruction) Script

func (ins Instruction) Script() string

Script formats Instruction for /bin/sh -c execution.

type Instructions

type Instructions []Instruction

Instructions is a list of shell commands.

type Pkg

type Pkg struct {
	Context      types.Variables `yaml:"-"`
	Name         string          `yaml:"name,omitempty"`
	Shell        Shell           `yaml:"shell,omitempty"`

	Variant      Variant         `yaml:"variant,omitempty"`
}

Pkg represents build instructions for a single package.

func NewPkg

func NewPkg(baseDir, fileName string, contents []byte, vars types.Variables) (*Pkg, error)

NewPkg loads Pkg structure from file.

func (*Pkg) Validate

func (p *Pkg) Validate() error

	Vars   types.Variables   `yaml:"vars,omitempty"`
	Labels map[string]string `yaml:"labels,omitempty"`
	Format string            `yaml:"format"`
}

Pkgfile describes structure of 'Pkgfile'.

func NewPkgfile

func NewPkgfile(contents []byte) (*Pkgfile, error)

NewPkgfile loads Pkgfile from `[]byte` contents.

type Shell

type Shell string

Shell is a path to the shell used to execute Instructions.

func (Shell) Get
