This project tries to make a sbt plugin for the awesome jib project from google.
Add the following lines in project/plugins.sbt:
addSbtPlugin("de.gccc.sbt" % "sbt-jib" % "<sbt-jib-version>")
libraryDependencies += "com.google.cloud.tools" % "jib-core" % "<jib-core-version>"You can find the latest jib-core version in their release list.

There are a couple of ways to supply credentials to the image pull and push operations done by jib. The following sources are tested in order:
- Environment variables:
JIB_BASE_IMAGE_USERNAME+JIB_BASE_IMAGE_PASSWORDfor pulling the base image,JIB_TARGET_IMAGE_USERNAME+JIB_TARGET_IMAGE_PASSWORDfor pushing the target image - SBT credentials: The plugin looks for a
credentialsentry that matches the host of the image registry - The
$HOME/.docker/config.jsonfor credentials and credential helpers - A set of well known credential helpers
- The credential helpers supplied by
jibBaseImageCredentialHelperorjibTargetImageCredentialHelper
This snippet shows how to inject a Java Agent (Kanela) into a container via jibExtraMappings.
build.sbt
//...project stuff...
javaAgents += "io.kamon" % "kanela-agent" % "1.0.5" % "dist;runtime;compile"
//...project stuff...
jibBaseImage := "openjdk:11-jre"
jibName := "my-service"
jibRegistry := "some-ecr-repository"
jibUseCurrentTimestamp := true
jibCustomRepositoryPath := Some(jibName.value)
jibJvmFlags := List("-javaagent:/root/lib/kanela-agent.jar")
jibExtraMappings := {
//javaAgents, Modules and ResolvedAgent come from the sbt-javaagent plugin
val resolved = javaAgents.value.map { agent =>
update.value.matching(Modules.exactFilter(agent.module)).headOption map {
jar => ResolvedAgent(agent, jar)
}
}
for {
resolvedAgent <- resolved.flatten
} yield {
resolvedAgent.artifact -> s"/root/lib/${resolvedAgent.agent.name}.jar"
}
}
jibTargetImageCredentialHelper := Some("ecr-login")
jibBaseImageCredentialHelper := Some("ecr-login")
