I am using a collaborative user, so it is not possible to change global folder. I have a git repository connected with several remotes. I need to access different remotes with different rsa key. Is it possible to insert the key path within native git, e.g. maybe inside .git/config, so I don't need to repeat entering the key path when i am doing clones,fetches,pushes,pulls?
Edit: I am aware of similar questions, for example Specific RSA keys per git repo, but it does not provide an exact answer to "per repo".
You need to replace the ssh url of your submodules by ssh url using ~/.ssh/config entry names (with ~ refering the $HOME of the global user)
Your ~/.ssh/config will include the path of the relevant private keys:
Host repo1
HostName git.myhost.lan
User git
IdentityFile /path/to/global/user/.ssh/repo1PrivateKey
And for the submodule repo1:
git config --file=.gitmodules submodule.repo1 .url repo1:user/repo1
# if needed to follow a branch (if not, skip it)
git config --file=.gitmodules submodule.repo1 .branch abranch
git submodule sync
git submodule update --init --recursive --remote
git add .
git commit -m "Change submodule repo1 url"
git push
Note: git config + git submodule sync can be replaced.
See "Git submodule url changed" and the new command (Git 2.25, Q1 2020)
git submodule set-url [--] <path> <newurl>
