Docker-compose and jenkinsfile with RoR - ruby-on-rails

Question

I'm trying to mount a jenkins pipeline, with jenkinsfile and docker-compose.
My docker-compose run fine. But the next steps (test stage in Jenkinsfile) don't run.
How to tell jenkins "ok fine the docker container is fine, you can do the next thing" but prevent the docker container to stop (this is why I put rails s at the end of the command"
Here the docker-compose.yml :
version: '3'
services:
db-test:
image: postgres
environment:
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=secret
- POSTGRES_DB=server_dev
volumes:
- ./tmp/db:/var/lib/postgresql/data
ports:
- "${POSTGRES_PORT}:5432"
web-test:
image: starefossen/ruby-node
command: bash -c "cd /app && bundle install && rake db:migrate && rails s"
volumes:
- /home/xero/jenkins/jenkins_home/workspace/project-open-source:/app # Workspace
- /home/cache/bundle:/usr/local/bundle # Cache gemfiles
- /home/cache/node_modules:/app/node_modules # Cache yarn files
- /home/xero/.ssh:/root/.ssh # SSH keys (for git)
ports:
- "3000:3000"
depends_on:
- db-test
And the Jenkinsfile :
pipeline {
agent any
options {
timeout(time: 1, unit: 'DAYS')
disableConcurrentBuilds()
}
stages {
stage("Init") {
agent any
steps { initialize() }
}
stage("Test") {
agent any
steps { test() }
}
}
}
def initialize() {
sh 'docker-compose -f docker-compose-jenkins.yml up --build --abort-on-container-exit'
}
def test() {
sh 'docker exec -ti web-test sh -c "cd app/ && bundle exec rspec -f documentation"'
}

Here my solution. I used retry and sleep, to wait that the dockers containers starts.
#!groovy
def message = "";
def author = "";
def getLastCommitMessage = {
message = sh(returnStdout: true, script: 'git log -1 --pretty=%B').trim()
}
def getGitAuthor = {
def commit = sh(returnStdout: true, script: 'git rev-parse HEAD')
author = sh(returnStdout: true, script: "git --no-pager show -s --format='%an' ${commit}").trim()
}
pipeline {
agent any
options {
timeout(time: 1, unit: 'DAYS')
disableConcurrentBuilds()
}
stages {
stage("Init RoR and DB") {
agent any
steps { initialize() }
}
stage("Tests") {
agent any
steps { test() }
post {
success {

}

post {

rocketSend channel: 'myproject-ci', emoji: ':x:', message: "Build failed - Commit : '${message}' by ${author}", rawMessage: true

}
}
def initialize() {
sh 'docker-compose -f docker-compose-jenkins.yml up --build --detach'
}
def test() {
try {
retry(3){
sleep 25
HEALTH = sh (
script: 'docker inspect -f \'{{json .State.Health.Status}}\' vpx-web-test',
returnStdout: true

echo "${HEALTH}"
if(HEALTH == "starting"){
return true

}
catch (exc) {

}
finally{
sh 'docker-compose -f docker-compose-jenkins.yml down'
}
