Deis Builder

Builder creates Docker images to be run elsewhere on the Deis platform. Builder itself also runs in a Docker container.

This Docker image is based on the official alpine:3.1 image.

Please add any issues you find with this software to the Deis Project.

Usage

Please consult the Makefile for current instructions on how to build, test, push, install, and start deis/builder.

Environment Variables

• DEBUG enables verbose output if set
• ETCD_PORT sets the TCP port on which to connect to the local etcd daemon (default: 4001)
• ETCD_PATH sets the etcd directory where the builder announces its configuration (default: /deis/builder)
• ETCD_TTL sets the time-to-live before etcd purges a configuration value, in seconds (default: 10)
• PORT sets the TCP port on which the builder listens (default: 2222)

Overview

Package pkg provides common libraries for the Deis builder.

The Deis builder is responsible for building slugs and docker images for use in the Deis on the Deis PaaS platform.

Index

• Constants
• func KillOnExit(c cookoo.Context, p *cookoo.Params) (interface{}, cookoo.Interrupt)
• func RunBuilder(sshHostIP string, sshHostPort int, gitHomeDir string, ...) int
• type BuildHook
• type BuildHookResponse
• type Config
• type ConfigHook
• type ControllerErrorResponse
• type ProcessType

Constants

const (
	StatusOk = iota
	StatusLocalError
)

Return codes that will be sent to the shell.

Functions

func KillOnExit

func KillOnExit(c cookoo.Context, p *cookoo.Params) (interface{}, cookoo.Interrupt)

KillOnExit kills PIDs when the program exits.

Otherwise, this blocks until an os.Interrupt or os.Kill is received.

Params:

This treats Params as a map of process names (unimportant) to PIDs. It then

attempts to kill all of the pids that it receives.

func RunBuilder

func RunBuilder(sshHostIP string, sshHostPort int, gitHomeDir string, sshServerCircuit *sshd.Circuit, pushLock sshd.RepositoryLock) int

RunBuilder starts the Builder service.

The Builder service is responsible for setting up the local container environment and then listening for new builds. The main listening service is SSH. Builder listens for new Git commands and then sends those on to Git.

Run returns on of the Status* status code constants.

}

Config represents a Deis application's configuration.

type ConfigHook

type ConfigHook struct {
	ReceiveUser string `json:"receive_user"`
	ReceiveRepo string `json:"receive_repo"`
}

ConfigHook represents a repository from which to extract the configuration and user to use.

type ControllerErrorResponse

type ControllerErrorResponse struct {
	ErrorMsg string `json:"detail"`
}

ControllerErrorResponse represents a controller's error response object.

type ProcessType

type ProcessType map[string]string

ProcessType represents the key/value mappings of a process type to a process inside a Heroku Procfile.
