Jenkins Git plugin cannot obtain ~/.ssh/config file-CodePudding

I'm using Exec into pod and try same

as you can see ssh command obtains config and it is trying to clone repo using 443 port(not 22 as jenkins). Then I put private key in .ssh folder and clone works perfectly. That means there isn't network issue.

Trying to clone in "Pipeline script" with git command in sh

        stage('Source Code Checkout') {
            steps {
                container('backend') {
                    script{
                       sh "git clone [email protected]:org/repo.git"

result

Trying to clone via GitSCM plugin in "Pipeline script"

        stage('Source Code Checkout') {
            steps {
                container('backend') {
                    git branch: 'main',
                        credentialsId: 'git_user_ssh',
                        url: '[email protected]:org/repo.git'

result

jfyi

Could someone please explain to me the cause of problem? Or how to specify port while cloning repo through Jenkins. Thanks in advance.

Jenkins home as was requested

                container('backend') {
                    script{
                        sh "cd $JENKINS_HOME || true"
                        sh """cd ~
                            pwd
                            ls -la
                        """

If you use a non-standard port, specify it in the URL

  git clone --help
  ...
  ssh://[user@]host.xz[:port]/path/to/repo.git/

I detected that next warning appears sometime

warning: JENKINS-30600: special launcher org.csanchez.jenkins.plugins.kubernetes.pipeline.ContainerExecDecorator$1@49c426f3; decorates RemoteLauncher[hudson.remoting.Channel@456b185:JNLP4-connect connection from 172.26.80.22/172.26.80.22:57964] will be ignored (a typical symptom is the Git executable not being run inside a designated container

So I decided to rebuild base jenkins/inbound-agent image with the following

FROM jenkins/inbound-agent:4.13-2-jdk11
ARG JENKINS_HOME=/home/jenkins
ENV JENKINS_HOME=$JENKINS_HOME
USER jenkins
RUN mkdir $JENKINS_HOME/.ssh && ssh-keyscan ssh.github.com > $JENKINS_HOME/.ssh/known_hosts
RUN echo "Host github.com\n    Hostname ssh.github.com\n   Port 443\n   User git" > $JENKINS_HOME/.ssh/config

and.. git checkout is working for now. I don't understand how jnlp container influences on checkout inside another container based on my "mycustomimage" image.
