使用 Docker Jenkins 容器管道构建 Docker 映像时未找到 Docker [英] Docker not found when building docker image using Docker Jenkins container pipeline

问题描述

我有一个 Jenkins 作为 Docker 容器运行，现在我想使用管道构建一个 Docker 映像，但 Jenkins 容器总是告诉 Docker not found.

I have a Jenkins running as a docker container, now I want to build a Docker image using pipeline, but Jenkins container always tells Docker not found.

[simple-tdd-pipeline] Running shell script
+ docker build -t simple-tdd .
/var/jenkins_home/workspace/simple-tdd-pipeline@tmp/durable-
ebc35179/script.sh: 2: /var/jenkins_home/workspace/simple-tdd-
pipeline@tmp/durable-ebc35179/script.sh: docker: not found

这是我运行 Jenkins 映像的方式:

Here is how I run my Jenkins image:

docker run --name myjenkins -p 8080:8080 -p 50000:50000 -v 
/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock 
jenkins

Jenkins 镜像的 DockerFile 是:https://github.com/jenkinsci/docker/blob/9f29488b77c2005bbbc5c936d47e697689f8ef6e/Dockerfile

And the DockerFile of Jenkins image is: https://github.com/jenkinsci/docker/blob/9f29488b77c2005bbbc5c936d47e697689f8ef6e/Dockerfile

推荐答案

你缺少 docker 客户端.在 Dockerfile 中这样安装它:

You're missing the docker client. Install it as this in Dockerfile:

RUN curl -fsSLO https://get.docker.com/builds/Linux/x86_64/docker-17.04.0-ce.tgz 
  && tar xzvf docker-17.04.0-ce.tgz 
  && mv docker/docker /usr/local/bin 
  && rm -r docker docker-17.04.0-ce.tgz
