ubuntu - 你如何从另一个 docker container-ubuntu 启动 docker

Question

我有一个在 ubuntu docker-container 中运行的 Jenkins。为了通过构建进行 dockerized，我还需要在此容器中运行 docker我的问题是我不明白如何启动守护进程 docker:

Dockerfile:

FROM ubuntu

# this is a non-interactive automated build - avoid some warning 

messages
ENV DEBIAN_FRONTEND noninteractive

# update dpkg repositories
RUN apt-get update 

# install wget
RUN apt-get install -y wget
RUN apt-get update -qq && apt-get install -qqy \
apt-transport-https \
ca-certificates \
curl \
tar \
lxc \
iptables

# Install Docker from Docker Inc. repositories.
RUN apt-get update && apt-get install -y docker.io

#install jenkins

...

 COPY jenkins.sh /usr/local/bin/jenkins.sh
 ENTRYPOINT ["/bin/tini", "--", "/usr/local/bin/jenkins.sh"]

我发现，它不是:

   RUN apt-get update && apt-get install -y docker.io    

但是

   RUN curl -sSL https://get.docker.com/ | sh

不需要jenkinsSlave
