篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了外部Jenkins调用容器中Slave配置实践相关的知识，希望对你有一定的参考价值。

1.Jenkins配置

实现动态生成的Slave节点并调用，解决构建项目出现slave节点任务堵塞或者是slave宕机问题。容器平台采用openshift。

参考配置文档：https://blog.csdn.net/felix_yujing/article/details/78725142

1.1 jenkins jnlp配置

1.2.Kubernetes配置

名称：默认使用Kubernetes即可

Kubernetes地址：填写paas平台地址

Kubernetes证书：填写paas平台中名称空间中的jenkins的secret中的token，选择ca.crt内容。

Kubernetes命名空间：填写jenkins的项目空间。

凭据：通证书一样的获取方式，只不过获取的不再试ca.crt内容，而是token。复制创建jenkins的凭据，凭据选择secret text格式。

2.Jenkins Slave配置

2.1 Dockerfile

镜像仓库：https://hub.docker.com/search/?q=openshift%20jenkins%20slave%20&type=image

FROM registry.it.com/openshift/jenkins-jnlp-slave:latest
USER root
 
RUN rm -fr /usr/share/jenkins/slave.jar
RUN rm -fr /usr/local/bin/jenkins-slave
 
COPY agent.jar /usr/share/jenkins/agent.jar
COPY jenkins-slave /usr/local/bin/jenkins-slave
 
RUN chmod 777 /usr/share/jenkins/agent.jar
RUN chmod 777 /usr/local/bin/jenkins-slave

2.2 JenkinsSlave脚本

#!/bin/bash
 
#env | grep "JENKINS" >>env.txt
#env | grep "JENKINS"
 
echo "[DEBUG] ----nohup java -jar /usr/share/jenkins/agent.jar -jnlpUrl ${JENKINS_URL}/computer/${JENKINS_AGENT_NAME}/slave-agent.jnlp -secret ${JENKINS_SECRET} -workDir /home/jenkins/agent >slave.log & -----"
 
 
java -jar /usr/share/jenkins/agent.jar -jnlpUrl ${JENKINS_URL}/computer/${JENKINS_AGENT_NAME}/slave-agent.jnlp -secret ${JENKINS_SECRET} -workDir "/home/jenkins/agent"
