My own git server (on EC2) git clone via ssh (permission denied) why?

Question

I can connect from my pc to my EC2 git server using ssh ( i specified port 22 cause default port is onother):

$ ssh -p22 [email protected]

this works fine, but when I try to clone I have som problems(again i specified port 22 cause default port is onother):

sudo git clone ssh://[email protected]:22/home/dev/some/stuff.git

this is the output:

[email protected]: Permission denied (publickey).

why????

Answer 1

The reason is because you're using sudo. OpenSSH uses the public keys of the current user to log in, and when you use sudo, they're the public keys of root, not your normal user.

If you want to clone as root, you either need to set up keys for root or set a /root/.ssh/config file that uses the normal user's keys via the IdentityFile option. For example, if your normal user is example and you're using an Ed25519 key, the file might look like this:

Host xxxxxxxxxx.compute.amazonaws.com
    IdentityFile /home/example/.ssh/id_ed25519
