How can I add a git submodule to git repo as a regular directory?

Let's see what it is

  • Create two git repo sub and test
  mkdir test sub
 cd test && git init && touch README && git add README && git commit -m "initialize the git repo" && cd ..
 cd sub && git init && touch README && git add README && git commit -m "initialize the sub git repo" && cd ..
  • Move sub repository to test
  mv sub test
 cd test 
 git add sub
 git commit -m "add sub directory"

I want to treat them as one git repository and delete them remotely, but now the files in the sub directory cannot be included?

How can I achieve this in a simple way, how to handle sub as a regular directory?

Use for this

I am trying to add jenkins data folder ( JENKINS_HOME ) to JENKINS_HOME images using Dockerfile for demonstration. ( ADD JEKINS_HOME /opt/jenkins )

 JENKINS_HOME Dockerfile

My jenkin has a scriptler plugin that contains a git repository for its purpose. Then it exists in my docker git repo image as below

  $ find jenkins-docker
 ./.git
 ./.git/ .. (skipped
 ./Dockerfile
 ./JENKINS_HOME
 ./JENKINS_HOME/scriptler
 ./JENKINS_HOME/scriptler/scripts
 ./JENKINS_HOME/scriptler/scripts/.git
 ./JENKINS_HOME/scriptler/scripts/.git / ... (skipped)
 ./JENKINS_HOME/scriptler/scripts/Sample.groovy
 ./JENKINS_HOME / ... (skipped)
 ./README

You can't seem to do that. The name .git hardcoded in the source code: https://github.com/git/git/blob/fe9122a35213827348c521a16ffd0cf2652c4ac5/dir.c#L1260

Perhaps one way is to create a script that renames .git to another and back before and after adding it to the repo, for example

In the working directory under scripts

 mv .git hidden-git

In dockerfile

 RUN mv $JENKINS_HOME/scriptler/scripts/hidden-git $JENKINS_HOME/scriptler/scripts/.git

Alternatively, it may be possible to pass the GIT_DIR environment GIT_DIR to the plugin so that it can use a different name.

 git add sub git commit -m "add sub directory"

They are not included, because test sees repo sub as a nested git repo, and writes only its gitlink or SHA1 , and not its url, as it would be if sub were added as a submodule.

First you need to click sub on the remote url, and then add it as a submodule for test to see the sub files.

  cd test git submodule add -- /url/to/sub

Or you will need to use a subtree

 cd test git subtree --prefix sub /url/to/sub master --squash
