I created three virtual machines ，A, B, C.
The three virtual machine networks are connected to each other ,can ping pong

In A , I created a GitLab private server by docker.
I can pull and push in IDEA

But In B, I want to git clone from A's gitlab server, and the SSH key is generated， I have put the public key on the gitlab server.

And I configured user Name and user.email.

CodePudding user response：

First, if you use an SSH key, you should use an SSH URL

git clone [email protected]:<user>/java_project.git

Second, this assumes:

• GitLab is on 192.168.56.100 the A machine
• GitLab manages (hosts) the java_project.git created under the GitLab user account
• GitLab user account SSH setting has the public key from the key pair created on B (which is hopefully what you mean by "I have put the public key on the gitlab server", because adding the public key directly on the A ~git/.ssh/authorized_keys would not work)

You can test from B your SSH connection to GitLab A server with:

ssh -Tv [email protected]
