我创建了两个Docker容器。一个Jenkins和一个运行Ubuntu Base的OpenSSH服务器的容器。我配置了Jenkins容器，购买了Jenkins镜像，并使用Dockerfile为openssh服务器创建了镜像。我生成了密钥文件并将公钥复制到openssh服务器的authorized_keys中。然后，当我尝试通过Jenkins容器使用ssh -i remote-key remote_user@remote-host登录openssh服务器时，它提示我给予密码。
下面是我的DockerFile和docker-compose DockerFile：

From ubuntu
Run apt-get update
Run apt-get install -y openssh-server
Run useradd -m -d /home/remote_user remote_user && \
    echo "remote_user:1234" |chpasswd  && \
    mkdir -p /home/remote_user/.ssh && \
    chmod 700 /home/remote_user/.ssh
Copy remote-key.pub /home/remote_user/.ssh/authorised_keys
Run chown remote_user:remote_user -R /home/remote_user/.ssh && \
    chmod 600 /home/remote_user/.ssh/authorised_keys
RUN service ssh start
EXPOSE 22
CMD ["/usr/sbin/sshd","-D"]`

docker-compose

version: '3'
services:
        jenkins:
                container_name: jenkins
                image: jenkins/jenkins
                ports:
                     -   "8080:8080"
                volumes:
                     -  "/home/sarthak/jenkins/jenkins1/jenkins1_home:/var/jenkins_home"
                networks:
                     -   net
        remote_host:
                container_name: remote-host
                image: remote-host
                build:
                        context: /home/sarthak/jenkins/jenkins1/
                networks:
                     -   net

通过密码登录是成功的，但我需要一个密码少登录。请帮帮忙
