Jenkins on docker not finding xml pytest report - docker

Question

I have rootless docker host, jenkins on docker and a fastapi app inside a container as well.
Jenkins dockerfile:
FROM jenkins/jenkins:lts-jdk11
USER root
RUN apt-get update && \
apt-get -y install apt-transport-https \
ca-certificates \
curl \
gnupg2 \
software-properties-common && \
curl -fsSL https://download.docker.com/linux/$(. /etc/os-release; echo "$ID")/gpg > /tmp/dkey; apt-key add /tmp/dkey && \
add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/$(. /etc/os-release; echo "$ID") \
$(lsb_release -cs) \
stable" && \
apt-get update && \
apt-get -y install docker-ce docker-ce-cli containerd.io docker-compose-plugin
This is the docker run command:
docker run -d --name jenkins-docker --restart=on-failure -v jenkins_home:/var/jenkins_home -v /run/user/1000/docker.sock:/var/run/docker.sock -p 8080:8080 -p 5000:5000 jenkins-docker-image
Where -v /run/user/1000/docker.sock:/var/run/docker.sock is used so jenkins-docker can use the host's docker engine.
Then, for the tests I have a docker compose file:
services:
app:
volumes:
- /home/jap/.local/share/docker/volumes/jenkins_home/_data/workspace/vlep-pipeline_main/test-result:/usr/src
depends_on:
- testdb
...
testdb:
image: postgres:14-alpine
...
volumes:
test-result:
Here I am using the volume create on the host when I ran the jenkins-docker-image. After running jenkins 'test' stage I can see that a report.xml file was created inside the host and jenkins-docker volumes.
Inside jenkins-docker
root#89b37f219be1:/var/jenkins_home/workspace/vlep-pipeline_main/test-result# ls
report.xml
Inside host
jap#jap:~/.local/share/docker/volumes/jenkins_home/_data/workspace/vlep-pipeline_main/test-result $ ls
report.xml
I then have the following steps on my jenkinsfile:
steps {
sh 'docker compose -p testing -f docker/testing.yml up -d'
junit "/var/jenkins_home/workspace/vlep-pipeline_main/test-result/report.xml"
}
I also tried using the host path for the junit step, but either way I get on jenkins logs:
Recording test results
No test report files were found. Configuration error?
What am I doing wrong?
