Cause analysis:

The identity verification failed when using SSH connection. After a lot of verification, it is found that this is the ID generated in openssh format_ A small Oolong of the RSA key. A line of “—- begin opensh private key —–” will be added before the key generated by openssh, but jgit cannot recognize this, so the verification will fail

Solution:

1. Upgrade version

Jgit solves this problem after version 5.2, so as long as the integrated jgit version in spring cloud config is greater than 5.2, such as after 3.1.0

2. Change the SSH key generation method

Delete the. SSH directory under the previously generated user directory and rerun the following command to specify the key in PEM format

ssh-keygen -m pem -t rsa -C "[email protected]"

Will ID_ The public key of rsa.pub is reconfigured to gitee, and an operation is performed through git, such as git push to update the local known_ hosts

Refer to this issue: 2.1.0.rc3 can not use local SSH settings #1251
