Connecting via ssh when building app with Jenkins – Docker

Tell me please.

I’m using Jenkins to build a project that runs in a docker container and I’ve run into a problem.

When executing this piece of code:

stage('deploy front') {
    when { equals expected: 'do', actual: buildFront }
    agent {docker{image 'ebiwd/alpine-ssh'}}

    steps{
        sh 'chmod 400 .iac/privatekey'
        sh "ssh -i   .iac/privatekey [email protected]"
    }
}

I get an error:

+ ssh -i .iac/privatekey [email protected]

Pseudo-terminal will not be allocated because stdin is not a terminal.

Warning: Permanently added ‘134.209.181.163’ (ECDSA) to the list of
known hosts.

bind: No such file or directory

unix_listener: cannot bind to path:
/root/.ssh/sockets/[email protected]

Moreover, if you execute the following script with your hands in the container, then everything works

ssh -i   .iac/privatekey [email protected]

container with Jenkins started with docker-compose.yaml

version: '3.1'
services:
  jenkins:
    image: jenkins/jenkins:2.277.1-lts
    container_name: jenkins
    hostname: jenkins
    restart: always
    user: root
    privileged: true

    ports:
      - 172.17.0.1:8070:8080
      - 50000:50000
    volumes:
      - /opt/docker/jenkins/home:/var/jenkins_home
      - /etc/timezone:/etc/timezone
      - /usr/bin/docker:/usr/bin/docker
      - /etc/localtime:/etc/localtime
      - /var/run/docker.sock:/var/run/docker.sock

What could be the problem?

    The problem was at this place:

    agent {docker{image 'ebiwd/alpine-ssh'}}

    When i change it to prev version, like:

    agent {docker{image 'ebiwd/alpine-ssh:3.13'}}

    Everything started working

    I have the same error in my Gitlab pipelines:

    bind: No such file or directory
unix_listener: cannot bind to path: /root/.ssh/sockets/[email protected]
lost connection

    I think that the error is related to this changeset.

    In particular, the ssh config file requires the path "~/.ssh/sockets" to be present. Since we are not using the script /usr/local/bin/add-ssh-key (custom script created for that image) this path is missing.

    I’ve opened an issue in the image project: Error using the image in CI/CD pipelines #10.
