[SOLVED] Docker Binding parse exception with testcontainers

Docker Binding parse exception with testcontainers

I would like to run some integrational tests which would include setting up a complete environment with org.testcontainers Docker Compose Module. I am new to Windows and Docker testing, same with the testcontainers.

Using versions:

Docker desktop community: 2.5.0.0
org.testcontainers:testcontainers:1.15.0
org.springframework.boot 2.3.4.

My code looks like the following:

@ClassRule
public static DockerComposeContainer environment = new DockerComposeContainer(
                    new File("C:\\dev\\myproject\\myapp\\docker-compose\\docker-compose.env.yml"),
                    new File("C:\\dev\\myproject\\myapp\\docker-compose\\docker-compose.yml"))
                    .withExposedService("myservice_1", 9999)
                    .withLocalCompose(true);

My compose files looks something likes this.

services:
  myservice:
    image: myapp/myservice:latest
    hostname: myservice
    volumes:
    - ../volumeDir:/app/volumeDir
    - ../config:/app/config
    expose:
    - 9999
    ports:
    - 9999:9999
    command: -Dspring.liquibase.enabled=true
    networks:
    - internet

It looks like some Binding error, the most significant part of the stacktrace:

>     java.lang.RuntimeException: java.lang.RuntimeException: org.testcontainers.shaded.com.fasterxml.jackson.databind.exc.ValueInstantiationException:

I have tried to change the path to absolute without any difference. Do you have any ideas what can make this bind unparseable?

Solution

This error is due to a current issue with Testcontainers and the recent Docker for Windows version. They are already aware of it and a fix seems close to being merged.

UPDATE: Version 1.15.1 is now available that fixes this bug.
