Note to self: PlayFramework disable IPv6

5 Apr
2017

To make sure that your Play! Application binds on an IPv4 Socket in your Docker-Container, add the following to your build.sbt file

javaOptions in Universal ++= Seq( // docker .... "-Djava.net.preferIPv4Stack=true" ) javaOptions in run += "-Djava.net.preferIPv4Stack=true" // dev mode

when running locally, you can also start sbt and tell it to prefer the IPv4 Stack.

sbt -J-Djava.net.preferIPv4Stack=true
