FROM ubuntu:14.04
## 更新和安裝
RUN apt-get update -qq
RUN apt-get upgrade -y
RUN apt-get install -y git nodejs npm vim nano
# git-it預設使用node來執行
RUN ln -s /usr/bin/nodejs /usr/bin/node
RUN npm install -g git-it
# ssh設定
RUN apt-get install -y openssh-server
RUN mkdir /var/run/sshd
RUN echo 'root:password' | chpasswd
RUN sed -i 's/PermitRootLogin without-password/PermitRootLogin yes/' /etc/ssh/sshd_config
RUN sed 's@session\s*required\s*pam_loginuid.so@session optional pam_loginuid.so@g' -i /etc/pam.d/sshd
EXPOSE 22
CMD ["/usr/sbin/sshd", "-D"]

docker build -t my-git-it .
docker run -d -P --name yaya my-git-it
docker port yaya 22會回傳可以ssh的port

ssh root@localhost -p xxxxx
git-it

version: '2'
services:
  client:
    build: ./
    ports:
      - "22"

docker-compose up -d
docker-compose scale client=3
docker-compose ps

強制登入後改密碼

在 Dockerfile 加上
RUN chage -d 0 root
