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

[elitzer2]

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?

[elitzer2]

Ok I was able to run sbt docker:publishLocal and changed the docker-compose.yml to use the image with name of "lightbend/akka-docker" and it worked.

That's correct, it's expected to be built from source

changed the docker-compose.yml to use the image with name of "lightbend/akka-docker"

Oh, that should be consistent. Would you be interested in preparing a PR to make sure docker:publishLocal publishes with the name lightbend/akka-sample-cluster-docker-compose-scala?

[raboof]

(I suspect sbt takes the project name from the directory name and you put the project in a folder named akka-docker - so it might just be a matter of explicitly adding name := "akka-sample-cluster-docker-compose-scala" to the build.sbt)

I can try and take a look in the next week. I’m currently in the middle of finishing up my final project for grad school so don’t have much extra time.

Yup, that fixed it!

[elitzer2]

@raboof I also noticed some unused import warnings in ClusteringApp.scala. Want me to fix those?

[raboof]

@elitzer2 yes, I'd much appreciate it! (meanwhile closing this issue as #27 fixes it)

[alvico]

I've encountered the same issue, and I don't really know why, it just happened after I removed the images from my local docker repository.

[raboof]

@alvico we don't publish docker images for this example, you're supposed to sbt docker:publishLocal it yourself to your local docker repository.

Perhaps we should not use the lightbend/ organization to make the error message more clear?

[alvico]

thanks raboof, fixed the problem, had several imports messed up due intellij optimise imports... together with the cleaning of the local docker images causes quite a mess in my local project, managed to fix everything and now works faultless. You could close the issue, although I would agree on the suggestion of not using the lightbend organisation.
