创建可以ssh登录的docker

1.在宿主机上安装docker
yum install docker-io -y

---

2.创建run.sh

#！/bin/bash/usr/sbin/sshd -D

3.生成密钥对
ssh-keygen -trsa
cat ~./ssh/id_rsa.pub > authorized_keys

4.创建Dockerfile

FROM ubuntu:14.04#安装sshdRUN apt-get updateRUN apt-get install -y openssh-server#设置不用密码的登录方式RUN sed -ri 's/session    required     pam_loginuid.so/#session    required     pam_loginuid.so/g' /etc/pam.d/sshd#设置root密码RUN echo 'root:root' |chpasswd#把文件放到镜像里ADD authorized_keys /root/.ssh/authorized_keysADD run.sh /run.shRUN chmod 755 /run.sh#允许以root的身份ssh登录RUN sed -i 's/PermitRootLogin without-password/PermitRootLogin yes/g' /etc/ssh/sshd_config#暴露ssh的端口EXPOSE 22CMD ["/run.sh"]

4.创建镜像
docker build -t sshd：ubuntu .

5.运行容器
docker run -d -p 10022:22 sshd:ubuntu
