reactive-docker

A fully reactive client for the docker remote API.

• fully async and non-blocking design
• full typesafety
• async streaming capabilities using enumerators (e.g. attaching to docker events stream)
• supports latest docker remote API v1.10

pending features:

• docker build (implemented but not tested yet)
• simplify API usage by providing additional convenience methods e.g. docker.run or docker.pull
• publish sbt artifacts

Installation

As reactive-docker still is in a very early stage of development no artifacts have been published yet. To use it you simply need to:

• git clone
• sbt publishLocal
• include into your SBT project "com.kolor" %% "reactive-docker" % "0.1-SNAPSHOT"

Sample Usage

import com.kolor.docker.api._
import com.kolor.docker.api.json.Formats._
import scala.concurrent.ExecutionContext.Implicits.global


implicit val docker = Docker("localhost")

val maybeImages = docker.images()
val maybeContainers = docker.containers()

for {
	images <- maybeImages
	containers <- maybeContainers
} yield {
	images.map(i => println(s"Image: $i"))
	containers.map(c => println(s"Container: $c"))
}

create a new container from busybox image and start it:

import com.kolor.docker.api._
import com.kolor.docker.api.json.Formats._
import scala.concurrent.duration.Duration
import scala.concurrent.Await
import play.api.libs.iteratee._
import scala.concurrent.ExecutionContext.Implicits.global


implicit val docker = Docker("localhost")
val timeout = Duration.create(30, SECONDS)

val cmd = Seq("/bin/sh", "-c", "while true; do echo hello world; sleep 1; done")
val containerName = "reactive-docker"
val imageTag = RepositoryTag.create("busybox", Some("latest"))
val cfg = ContainerConfig("busybox", cmd)


// create image, returns a list of docker messages when finished
val messages = Await.result(docker.imageCreate(imageTag), timeout)

messages.map(m => println(s"imageCreate: $m"))

// create container
val containerId = Await.result(docker.containerCreate("busybox", cfg, Some(containerName)), timeout)._1

// run container
Await.result(docker.containerStart(containerId), timeout)
println(s"container $containerId is running")
