使用自定义代理映像配置Kubernetes插件Jenkins

Question

我正在尝试使用自定义图像在Jenkins中配置kubernetes插件，但是当我启动管道时出现此错误：

Started by user unknown or anonymous
Running in Durability level: MAX_SURVIVABILITY
[Pipeline] Start of Pipeline
[Pipeline] podTemplate
[Pipeline] {
[Pipeline] node
Still waiting to schedule task
‘testjenkinsslaveagent-54-blfkj-1zp9j-lbn6q’ is offline

其中testjenkinsslaveagent是我的管道名称。 Kubernetes插件配置为以下： 管道si定义如下：

podTemplate(containers: [
        containerTemplate(name: 'jnlp', image: 'registry.gitlab.com/xxxx/dockerimages:latest', ttyEnabled: true, command: '/bin/sh'),
],volumes: [hostPathVolume(hostPath: '/var/run/docker.sock', mountPath: '/var/run/docker.sock')]) {

    node(POD_LABEL) {
        stage('Run') {
            container('my-slave') {
                sh 'echo hello world'
                sh 'ifconfig'
                sh 'sudo docker images ls'
            }
        }

    }
}

Jenkins版本为2.176.3，所有插件均已更新。

因为我需要在代理中使用docker，所以我像这样修改了一个现有的Dockerimage（它在本地有效）：

ARG version=4.0.1-1
FROM jenkins/slave:$version

ARG version
MAINTAINER Oleg Nenashev <o.v.nenashev@gmail.com>
LABEL Description="This is a base image, which allows connecting Jenkins agents via JNLP protocols" Vendor="Jenkins project" Version="$version"

ARG user=jenkins

USER root

COPY jenkins-agent /usr/local/bin/jenkins-agent
RUN chmod +x /usr/local/bin/jenkins-agent &&\
    ln -s /usr/local/bin/jenkins-agent /usr/local/bin/jenkins-slave


# Install docker routine
RUN echo 'Installing docker routine ...'
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
RUN usermod -a -G docker jenkins
RUN mkdir -p /home/jenkins/.ssh && \
    chown -R 1000:1000 /home/jenkins/.ssh

USER ${user}

ENTRYPOINT ["jenkins-agent"]

问题是我的自定义代理docker映像被忽略，而Kubertete的插件默认映像是即时的。关于如何正确设置这些的任何想法或任何工作教程？ 谢谢

您需要更新 jenkinsfile 中的 POD_LABEL： 节点（POD_LABEL）{ 这应该使用您的 pod 标签名称更新为 节点（jnlp-slave）{
