Running sonarqube as container with same network as host - docker

Question

I am trying to run a Sonarqube container that gets created as below Dockerfile:
FROM node:15-buster
################
# Install java #
################
RUN apt-get update && \
DEBIAN_FRONTEND=noninteractive \
apt-get -y install openjdk-11-jre-headless && \
apt-get clean && \
rm -rf /var/lib/apt/lists/*
############################
# Install SonarQube client #
############################
WORKDIR /root
RUN apt-get install -y curl grep sed unzip
RUN curl --insecure -o ./sonarscanner.zip -L https://binaries.sonarsource.com/Distribution/sonar-scanner-cli/sonar-scanner-cli-4.4.0.2170-linux.zip
RUN unzip -q sonarscanner.zip
RUN rm sonarscanner.zip
RUN mv sonar-scanner-4.4.0.2170-linux sonar-scanner
ENV SONAR_RUNNER_HOME=/root/sonar-scanner
ENV PATH $PATH:/root/sonar-scanner/bin
# Include Sonar configuration and project paths
COPY ./sonar/sonar-runner.properties ./sonar-scanner/conf/sonar-scanner.properties
# Ensure Sonar uses the provided Java for musl instead of a borked glibc one
RUN sed -i 's/use_embedded_jre=true/use_embedded_jre=false/g' /root/sonar-scanner/bin/sonar-scanner
My sonar link is not accessible , I did confirm on all the network checks like checking its reachability from my Jenkins host and its fine. Only it is the Sonarqube container from where the link is unreachable:
ERROR: SonarQube server [https://sonar.***.com] can not be reached
Below is my Jenkinsfile stage for Sonarqube:
stage('SonarQube') {
agent
{dockerfile { filename 'sonar/Dockerfile'
args '-u root:root'
}
}
steps {
withCredentials([string(credentialsId: 'trl-mtr-sonar-login', variable: 'SONAR_LOGIN')]) {
script {
sh 'sonar-scanner -Dsonar.login="$SONAR_LOGIN" -Dsonar.projectBaseDir=. || true'
}
}
}
}
Plugin 'withCredentials' is used in above snippet of code. I would want to add the network in container just like host.
As a result of browsing I found manual command to do the same and also the docker.image.inside plugin. I still can not consolidate all to be used in my pipeline for sonarqube :
# Start a container attached to a specific network
docker run --network [network] [container]
# Attach a running container to a network
docker network connect [network] [container]
I also created the stage as below but even it seems to be failing:
stage('SonarTests') {
steps{
docker.image('sonar/Dockerfile').inside('-v /var/run/docker.sock:/var/run/docker.sock --entrypoint="" --net bridge')
{
sh 'sonar-scanner -Dsonar.login="$SONAR_LOGIN" -Dsonar.projectBaseDir=. || true'
}
}
}
Could someone please assist here.
