akka / akka-sample-cluster-docker-compose-scala

akka-docker-cluster-example

An example akka-cluster project with docker support. See the blog post. Uses SBT Native Packager.

How to Run

In SBT, just run docker:publishLocal to create a local docker container.

To run the cluster, run docker-compose up. This will create 3 nodes, a seed and two regular members, called seed, c1, and c2 respectively.

While running, try opening a new terminal and (from the same directory) try things like docker-compose stop seed and watch the cluster nodes respond.

akka-sample-cluster-docker-compose-scala's Issues

pull access denied for lightbend/akka-sample-cluster-docker-compose-scala

Versions used

Using latest code on GitHub as of today 6/4/19 and running docker-compose up

Expected Behavior

The docker containers start up and run as described in README.

Actual Behavior

Error response from daemon: pull access denied for lightbend/akka-sample-cluster-docker-compose-scala, repository does not exist or may require 'docker login'

It seems like the image in the Dockerfile doesn't exist in the Docker Hub?

Link on Lightbend website is directed to the Java app

Hello,

The link to the akka cluster project in Scala is directing to the Java Project on https://developer.lightbend.com/start/?group=akka&project=akka-sample-cluster-docker-compose-scala
when clicking on "Create a project for me"

Best,

JNI Error, java.lang.UnsupportedClassVersionError, while running docker-compose up

Im using this version of java:

openjdk version "10.0.2" 2018-07-17
OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.4)
OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.4, mixed mode)

And when running docker-compose up all of the containers return the same error:

c2_1 | Error: A JNI error has occurred, please check your installation and try again
c2_1 | Exception in thread "main" java.lang.UnsupportedClassVersionError: com/example/ClusteringApp has been compiled by a more recent version of the Java Runtime (class file version 54.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Issue with sbt docker:publishLocal

Versions used

I ran the same sample on Pop_Os (Ubuntu) and the output is in the expected behavior. When I run the same in MacOs I get the issues. The app still comes up and is running.
