A plugin to run docker containers in sbt.
Add the sbt-docker-run plugin to your project/plugins.sbt file:
addSbtPlugin("ch.timo-schmid" % "sbt-docker-run" % "0.1.1")When the plugin is enabled, you can add docker containers to your build, very similar to docker-compose:
lazy val root = (project in file("."))
.settings(
dockerContainers := Seq(
// Define a container for mysql
DockerContainer(
id = "myapp_mysql",
name = "mysql",
version = "5.7",
ports = Seq(
3306 `:` 3306
),
environment = Map(
"MYSQL_ROOT_PASSWORD" -> "s3cr3t",
"MYSQL_DATABASE" -> s"db_myapp",
"MYSQL_USER" -> "db",
"MYSQL_PASSWORD" -> "123456"
),
volumes = Map(
file("./data/mysql") -> "/var/lib/mysql"
)
)
)
)Once you're done writing your container definitions, sbt-docker-run will automatically start docker containers when you call the run task in sbt (if you are in an sbt session, use reload to update all changes):
$ sbt ~run

Once the container is started, it will not be restarted again - sbt-docker-run checks the running container for different configuration variables using docker inspect:
$ sbt ~run
