Simple ambassador container

The Simple Ambassador Container (let's just call it the ambassador) is a reusable container which can be added to your stack to represent a remote service. Using an ambassador your application can discover remote services using docker's standard links features.

Usage

Example usage:

REDIS_REMOTE_IP=1.2.3.4

shykes

type Driver interface {
        Create(id, parent string) error
        Remove(id string) error

        Get(id string) (dir string, err error)

        Diff(id string) (archive.Archive, error)
        DiffSize(id string) (bytes int64, err error)
        Changes(id string) ([]Change, error)

shykes

interface GraphBackend {
  Init(home string) error
  Nuke() error
  Create(img *Image, layer Archive) error
  Delete(img *Image) error
  Mount (img *Image, dest string) error
  UnmountAll (img *Image) error
  DiffList(*Image, dest string) ([]Change, error)
  DiffLayer(*Image, dest string) (Archive, error)
}

Links - Spec

Links are a way of expressing a relationship between one container and another. When you link a container, you create a parent/child relationship between the two. As a side effect links also allow you to name containers and reference them by name. Containers can be references by more than one name.

Initially links will be expressed by injecting the child's data into the parent's environment accessible via namespaced variables:

####Examples

• REDIS_ENV_{key}={value}
• REDIS_PORT={value}

func TestTree(t *testing.T) {
  tree := NewTree("/path/to/db")

  // List all root containers
  names, _ := tree.List("/")
  for _, name := range names {
    fullPath := path.Join("/", name)
    id, _ := tree.Get(fullPath)
    fmt.Printf("%s is a link to %s\n", fullPath, id)
