I am new to Kubernetes, While I am creating a Jenkins pod in GKE, /var/jenkins_home/init.groovy.d files are not loading(Only tcp-slave-agent-port.groovy file is loaded). I have created my jenkins image (for populating plugins and uploading groovy script) from the official image. And if I am running the deployment without volume attachment, everything will works fine. Anyone can help me please?

My Docker file:

FROM jenkins
MAINTAINER Bujail
# Install plugins
COPY plugins.txt /usr/share/jenkins/plugins
RUN /usr/local/bin/install-plugins.sh $(cat /usr/share/jenkins/plugins | tr '\n' ' ')
# Setup Security with User
COPY security.groovy /var/jenkins_home/init.groovy.d/security.groovy
# Disabling setup wizard
ENV JAVA_OPTS="-Djenkins.install.runSetupWizard=false -Djenkins.CLI.disabled=true"

Groovy Script:

#!groovy
import jenkins.model.*
import hudson.security.*
import jenkins.security.s2m.AdminWhitelistRule

def instance = Jenkins.getInstance()

println "--> creating local user 'admin'"

def hudsonRealm = new HudsonPrivateSecurityRealm(false)
hudsonRealm.createAccount('admin','admin@123')
instance.setSecurityRealm(hudsonRealm)

def strategy = new
hudson.security.FullControlOnceLoggedInAuthorizationStrategy()
strategy.setAllowAnonymousRead(false)
instance.setAuthorizationStrategy(strategy)

println "--> Enable Agent → Master Access Control"
Jenkins.instance.getInjector().getInstance(AdminWhitelistRule.class)
.setMasterKillSwitch(false);
instance.save()

And Jenkins will load without security enabled. If I try to enable security manually, I won't persistent.
