這是我第一次使用Docker。我安裝了它並且守護程序服務正在運行，正如所說的那樣。所以，我有一個簡單的網絡應用程序，用Play Framework和Scala語言構建。在我運行「sbt docker：publishLocal」之後，我得到了「構建的圖像play-scala-book：1.0-SNAPSHOT」成功。我導出「DOCKER_HOST = tcp：//192.168.0.8：2375」。我built.sbt是>>如何dockerize我的play scala應用程序？
// import NativePackagerKeys._
// setting a maintainer which is used for all packaging types
maintainer := "Felipe Oliveira Gutierrez"
// exposing the play ports
dockerExposedPorts in Docker := Seq(9000, 9443)
name := """play-scala-book"""
version := "1.0-SNAPSHOT"
lazy val root = (project in file(".")).enablePlugins(PlayScala)
scalaVersion := "2.11.7"
libraryDependencies ++= Seq(
jdbc,
cache,
ws,
evolutions,
"com.typesafe.play" %% "anorm" % "2.4.0",
"commons-codec" % "commons-codec" % "1.6",
specs2 % Test
)
resolvers += "scalaz-bintray" at "http://dl.bintray.com/scalaz/releases"
// enablePlugins(JavaAppPackaging)
但是當我運行 「泊塢窗運行-p 9000：9000播放斯卡拉書：1.0快照」 我得到這個錯誤>>

在我的conf/application.conf我有這個>

你想解決德數據庫錯誤或應用祕密錯誤？ – Hugo
我認爲這是使我能夠dockerize「的主要錯誤」無法啓動服務器。@ 708n7c3af：數據庫'默認'需要進化！「。但是我的圖書館已經有了進化。我只想dockerize我的應用 –
也許它找不到你的application.conf文件？嘗試在你的application.conf中配置一個好的應用程序祕密。如果這不能解決應用程序祕密問題，並且Michael Vaughan的答案也不起作用，那麼您可能需要檢查您的應用程序是否可以找到application.conf。 – Hugo
