Generic containers not starting

[darrenbeck-te]

Expected Behavior

In a gradle-kotlin project with version 4.4.5 of the io.micronaut.test-resources plugin, add a generic container definition to the application.properties config (wiremock in this case):

test-resources.containers.wiremock.image-name=wiremock/wiremock:3.1.0-1-alpine
test-resources.containers.wiremock.hostnames[0]=wiremock.host
test-resources.containers.wiremock.exposed-ports[0].wiremock.port=8080

Start the application with ./gradlew run and the defined wiremock container will start.

I can get the JDBC module working without issue, databases are started and the properties are resolved for the defined datasources, but generic containers don't seem to start.

I have tried to bind the resolved properties (wiremock.port and host in this case) to a component but that just causes startup to fail as they cannot be resolved.

I suspect I'm missing something here, but I can't work out what.

Actual Behaviour

The container does not start.

Enabling debug logging on the server shows the following output:

It seems to work as intended from my side. Properties are resolved lazily, so you need something which consumes the properties that you have defined. I added the following controller to your sources, and as soon as I hit the / endpoint then the container is resolved:

package com.example;

import io.micronaut.http.annotation.Controller;
import io.micronaut.context.annotation.Value;
import io.micronaut.http.annotation.Get;


@Controller("/")
class Foo(@Value("\${wiremock.port}") val port: Int) {
      @Get
      fun home() = "Port $port"
}
