我是码头工人的新手。我只是试着在我的本地机器(Ubuntu 16.04)上使用docker和Jenkins。
我用下面的管道脚本配置了一个新作业。
node {
stage('Build') {
docker.image('maven:3.3.3').inside {
sh 'mvn --version'
}
}
}
但是它失败了，错误如下:
在unix:///var/run/ Docker .sock试图连接到Docker守护进程套接字时被拒绝

使用下面的dockerfile
FROM jenkins/jenkins
USER root
# Install Docker
RUN apt-get update && \
apt-get -y install apt-transport-https \
ca-certificates \
curl \
gnupg2 \
software-properties-common && \
curl -fsSL https://download.docker.com/linux/$(. /etc/os-release; echo "$ID")/gpg > /tmp/dkey; apt-key add /tmp/dkey && \
add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/$(. /etc/os-release; echo "$ID") \
$(lsb_release -cs) \
stable" && \
apt-get update && \
apt-get -y install docker-ce
# Compose
RUN curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && chmod +x /usr/local/bin/docker-compose
RUN usermod -aG docker jenkins
RUN usermod -aG root jenkins
USER jenkins
其他回答
我的第一个解决方案是:
usermod -aG docker jenkins
usermod -aG root jenkins
chmod 664 /var/run/docker.sock
但没有一个对我有用，我试过了:
chmod 777 /var/run/docker.sock
这是可行的，但我不知道这是否正确。
在我的情况下，这将成功工作。 导航本地回购并输入此命令。
sudo chmod 666 /var/run/docker.sock

这对我很管用!
示例docker-compose:
version: "3"
services:
jenkins:
image: jenkinsci/blueocean
privileged: true
ports:
- "8080:8080"
volumes:
- $HOME/learning/jenkins/jenkins_home:/var/jenkins_home
environment:
- DOCKER_HOST=tcp://socat:2375
links:
- socat
socat:
image: bpack/socat
command: TCP4-LISTEN:2375,fork,reuseaddr UNIX-CONNECT:/var/run/docker.sock
volumes:
- /var/run/docker.sock:/var/run/docker.sock
expose:
- "2375"
使用下面的dockerfile
FROM jenkins/jenkins
USER root

apt-get -y install apt-transport-https \

apt-get -y install docker-ce
# Compose
RUN curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && chmod +x /usr/local/bin/docker-compose
RUN usermod -aG docker jenkins
RUN usermod -aG root jenkins
USER jenkins
我将jenkins用户添加到根组，并重新启动jenkins，它开始工作。
sudo usermod -a -G root jenkins
sudo service jenkins restart
