dockerfile 创建 ssh 镜像

一、编辑Dockerfile

vim Dockerfile

# SSH
# Version 0.0.1

# IMAGES
FROM 192.168.0.216:5000/centos

# MAINTAINER
MAINTAINER hongxue hongxue@showjoy.com

# YUM
RUN yum -y update
RUN yum -y install vim net-tools openssh-server

# SSH
RUN ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key
RUN ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
RUN ssh-keygen -t ed25519 -f /etc/ssh/ssh_host_ED25519_key
RUN ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key

RUN mkdir /var/run/sshd
RUN sed -i 's/session    required     pam_loginuid.so/#session    required     pam_loginuid.so/g' /etc/pam.d/sshd
RUN echo "root:xxxxxxx" | chpasswd

# EXPOSE
EXPOSE 22

CMD ["/usr/sbin/sshd","-D"]

二、构建镜像

docker build -t container_ssh .

三、运行镜像生成容器

[root@docker Dockerfile]# docker images | grep container_ssh
container_ssh     latest     88f1388b6337     2 minutes ago     328.1 MB

[root@docker Dockerfile]# docker run -d -it -p 122:22 --name ssh container_ssh
3e5442e5b35fa72fadfc33fe52db03b645544f39b58cf164ed43f8bb799213b2

四、验证ssh登录是否成功
