一 全局配置项设置
- 需要添加全局变量项,例如名称docker,路径/usr/local
- 添加一个jenkinsfile文件,用于运行docker命令
pipeline {
agent any
tools{
gradle "gradle"
}
stages {
stage('init') {
steps {
script{
def dockerPath = tool 'docker' //全局配置里的docker
env.PATH = "${dockerPath}/bin:${env.PATH}" //添加了系统环境变量上
}
}
}
stage('Build') {
steps {
script{
sh "docker --version"
}
}
}
}
}
注意:我们需要把docker的路径添加到env环境变量里才可以使用docker命令,这个我试了很多次。
二 添加jenkins用户到docker组
上面的操作完成之后,你的docker --version
是可以打印了,但还不能执行docker命令,还需要你把jenkins用户添加到docker
用户组里。
没有添加用户组会有这个错误提示
docker run --rm -v /Users/Shared/Jenkins/Home/workspace/helloJava:/src --user root --privileged=true alpine:3.6 sh -c 'cp /src/src/main/docker/Dockerfile /src/build/libs'
docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.39/containers/create: dial unix /var/run/docker.sock: connect: permission denied.
当前用户添加到docker组
sudo gpasswd -a ${USER} docker
#或者将当前用户直接加到文件中
sudo echo "docker:x:994:${USER}" >> /etc/group
#查看docker用户组成员
cat /etc/group |grep docker
#重新启动docker服务
sudo systemctl restart docker
# 赋予权限
sudo chmod a+rw /var/run/docker.sock
修改jenkins用户的拥有者
sudo launchctl unload /Library/LaunchDaemons/org.jenkins-ci.plist
sudo vim /Library/LaunchDaemons/org.jenkins-ci.plist
sudo chown -R lind.zhang:docker /Users/Shared/Jenkins/
sudo chown -R lind.zhang:docker /var/log/jenkins/
启动jenkins
sudo launchctl load /Library/LaunchDaemons/org.jenkins-ci.plist
大功告成
