This repository contains the source for building various versions of the Scala application as a reproducible Docker image using source-to-image. The resulting image can be run using Docker.

Versions

Scala versions currently provided are:

• SBT 0.13

Java versions currently provided are:

• Java 1.8.0

CentOS versions currently supported are:

• CentOS 7

Installation

• CentOS based image

  To build a Scala image from scratch run:

  $ git clone https://github.com/ticketfly/sti-scala.git
  $ cd sti-scala/sbt-0.13-java-8
  $ make build
  

Usage

To build a simple Scala-sample-app application using standalone STI and then run the resulting image with Docker execute:

• For CentOS based image

  $ sti build https://github.com/ticketfly/sti-scala.git --context-dir=sbt-0.13-java-8/test/test-app/ ticketfly/scala-0.13-java-8-centos7 scala-test-app
  $ docker run -p 9000:9000 scala-test-app
  

Accessing the application:

$ curl 127.0.0.1:9000

Test

This repository also provides a S2I test framework, which launches tests to check functionality of a simple Scala application built on top of the sti-Scala image.

Users can choose between testing a Scala test application based on a RHEL or CentOS image.

• CentOS based image

  $ cd sti-scala/sbt-0.13-java-8
  $ make test
