Why I am getting error 'Server rejected the 1 private key' error on setting up ssh-slave Docker image
I am running both Jenkins master and slave as Docker containers by using jenkins/jenkins:lts and jenkins/ssh-slave image on Ubuntu. Following are the steps:
- Ran
ssh-keygeninside the jenkins-master container (docker exec -it container_id bash) to generate the ssh keys - Added the generated public key to authorized_keys file inside ssh-slave container using dockerfile
- Added private key inside Jenkins credentials as per this link
I have looked at many questions related to this issue on Stack Overflow but I am stuck with following error:
[02/08/19 20:31:06] [SSH] Opening SSH connection to ###.##.#.#:22.
[02/08/19 20:31:06] [SSH] SSH host key matches key in Known Hosts file. Connection will be allowed.
ERROR: Server rejected the 1 private key(s) for jenkins (credentialId:worker-ssh/method:publickey)

Authentication failed.

COPY /.ssh/id_rsa.pub /.ssh/authorized_keys
RUN chmod 744 /.ssh/authorized_keys

"I added my private key in the credentials to ssh into the slave" - you need to add your public key to the authorized_keys file on the slave, not your private key.

I have added my public key in authorized_key folder at slave and private key as a credential to ssh on Jenkins. I have updated my question with clear description.
