我在GitHub上传了一个Django项目，我需要将它与jenkins链接。我在Ubuntu 20.04机器上安装了Jenkins和Docker服务。
我用我的repo配置了Jenkins服务器，并安装了所有建议的plggins+docker管道插件。
之后，我创建了一个Jenkinsfile，它使用docker代理在python docker容器中运行stage，但我得到了"詹金斯没有"码头工人"的标签；在控制台输出中。我试图在项目设置中添加标签docker，但仍然出现相同的错误！
这是我的詹金斯档案：
pipeline {
agent any
stages {
stage("install pip dependencies") {
agent {
docker {
label "docker"
image "python:3.7"
}
}
steps {
withEnv(["HOME=${env.WORKSPACE}"]) {
sh "pip install virtualenv"
sh "virtualenv venv"
sh "pip install -r requirements.txt "
}
}
}
}}
我错过了什么？
谢谢！
该消息意味着您唯一可用的节点，恰好是您的Jenkins控制器，没有您在此块中的代理上所需的标签docker：
agent {
docker {
label 'docker'
image 'python:3.7'
}
}
将标签docker添加到控制器，然后重新启动Jenkins(需要识别标签更改，尽管这让我很惊讶。这可能是标记控制器本身的一个特点，因为如果可能的话，应该避免将作业安排在那里运行(解决了这个问题。

您的管道将如下所示：
pipeline {
agent {
label 'docker'
}
stages {
stage('install pip dependencies') {
steps {
withEnv(["HOME=${env.WORKSPACE}"]) {
sh'''
pip install virtualenv
virtualenv venv
pip install -r requirements.txt
'''
}
}
}
}
}
但是，在您需要遵循以下步骤使jenkins将docker容器作为奴隶运行之前：
- 在主机上安装docker
- 将jenkins添加到docker组：
sudo usermod -aG docker jenkins - 将文件
/lib/systemd/system/docker.service中的ExecStart=/usr/bin/dockerd行修改为以下ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock -H fd:// -s overlay2 --containerd=/run/containerd/containerd.sock - 运行
sudo systemctl daemon-reload和sudo systemctl restart docker - 在Jenkins中配置docker部分：
manage Jenkins -> manage nodes and clouds -> configure clouds -> add a new cloud -> docker在docker URL字段中键入tcp://127.0.0.1:2375 (or 4243)或unix:///var/run/docker.sock。配置代理，设置任何标签并在管道中使用
您可能需要关闭selinux。
