How do I resolve Testcontainers’ Ryuk connection error in Jenkins CI/CD on Windows for Spring Boot?

I am trying to run all my JUnit and integration tests in a Jenkins CI/CD pipeline for a Spring Boot application. I have set up Jenkins with a Groovy script, a Dockerfile, and a docker-compose.yml file.

Below is my groovy file:

GROOVYCopied
import hudson.plugins.git.UserRemoteConfig
import hudson.plugins.git.BranchSpec
import hudson.plugins.git.GitSCM
import jenkins.model.*
import org.jenkinsci.plugins.workflow.cps.CpsScmFlowDefinition

def instance = Jenkins.getInstance()

def jobName = "flightsearchapi"
def job = instance.getItem(jobName)

if (job != null) {
    job.delete()
}

def pipelineJob = instance.createProject(org.jenkinsci.plugins.workflow.job.WorkflowJob, jobName)
def definition = new CpsScmFlowDefinition(
        new GitSCM(
                [
                        new UserRemoteConfig("https://github.com/Rapter1990/flightsearchapi.git", null, null, null)
                ],
                [new BranchSpec("*/development/issue-2/implement-jenkins-for-ci-cd")],
                false, Collections.emptyList(),
                null, null, Collections.emptyList()
        ),
        "Jenkinsfile"
)
definition.setLightweight(true)
pipelineJob.setDefinition(definition)
pipelineJob.save()

println("Pipeline job '${jobName}' has been successfully created!")

Below is the Dockerfile:

Below is the docker-compose.yml file:

When I run docker-compose up -d and execute the pipeline, I get the following error:

This works on Linux but fails on Windows. What steps can I take to fix this issue?

Comments and answers suggest solutions such as overriding the Docker host address using the environment variable TESTCONTAINERS_HOST_OVERRIDE or modifying the Docker socket volume mount. Any insights or further suggestions to address this connection issue would be helpful.
