Configuring agents with Docker
info
Jenkins 2.289.3 LTS
** Generating an SSH key pair
ssh-keygen -t dsa -f ~/.ssh/jenkins_agent_key
*** Create a Jenkins SSH credential
1. Go to your Jenkins dashboard;
2.Go to Manage Jenkins option in main menu and click on credentials button;
3.select the drop option Add Credentials from the global item;
4.Fill the form:
Kind: SSH Username with private key;
id: jenkins
description: The jenkins ssh key
username: jenkins
Private Key: select Enter directly and press the Add button to insert your
private key from ~/.ssh/jenkins_agent_key
Passphrase: fill your passphrase used to generate the SSH key pair and then
press OK
** Creating your Docker agent
run the command to start your first agent:
docker run -d --rm --name=agent1 -p 22:22 \
-e "JENKINS_AGENT_SSH_PUBKEY=[your-public-key]" \
jenkins/ssh-agent:alpine
实际替换上你的pub key
docker run -d --rm --name=agent1 -p 222:22 \
-e "JENKINS_AGENT_SSH_PUBKEY=ssh-rsa

" \
jenkins/ssh-agent:alpine
Now run the following command to update the container environment:
$ VARS1="HOME=|USER=|MAIL=|LC_ALL=|LS_COLORS=|LANG="
$ VARS2="HOSTNAME=|PWD=|TERM=|SHLVL=|LANGUAGE=|_="
$ VARS="${VARS1}|${VARS2}"
$ docker exec agent1 sh -c "env | egrep -v '^(${VARS})' >> /etc/environment"
* config on web
Setup up the agent1 on jenkins.
1. Go to your Jenkins dashboard;
2. Go to Manage Jenkins option in main menu;
3.Go to Manage Nodes and clouds item;
4.Go to New Node option in side menu;
5.Fill the Node/agent name and select the type; (e.g. Name: agent1, Type: Permanent Agent)
6.Now fill the fields:
Remote root directory; (e.g.: /home/jenkins )
label; (e.g.: agent1 )
usage; (e.g.: only build jobs with label expression…)
Launch method; (e.g.: Launch agents by SSH )
Host; (e.g.: localhost or your IP address 一般是ip 不可能是自己机器 )
Credentials; (e.g.: jenkins )
Host Key verification Strategy; (e.g.: Manually trusted key verification … )
自己要注意的细节 因为母机的22不能再用了
固定 --
ssh 端口 222
Now press the button Launch agent and wait some seconds, then you should receive
the message: Agent successfully connected and online on the last log line.
Agent successfully connected
然后启动节点
如果遇到报错【The SSH key for this host is not currently trusted. Connections
will be denied until this new key is authorised.】
直接节点配置里面点trust key
agent1
Trust SSH Host Key
:~/tmp$ ssh -i id_rsa -p 222 [email protected]
我测试是可以login的呀
trouble shooting
java.io.IOException: Java not found on hudson.slaves.SlaveComputer@d48b725. Install Java 8 or Java 11 on the Agent. alpine 安装java apk add openjdk8 java目录 /opt/java/openjdk/bin/java 要安装这个插件 SSH Agent SSH build Agents 这两个搞得有点久 /home/jenkins 工作目录改成这个 /tmp好了 ? 不是的 Node and Label parameter nodelabelparameter Job Restrictions 插件 不然 I can't find “Restrict where this project can be run” in the configure page 就是手工添加的了 有如当年在xk 选择git 版本一样 参数化构建过程 -->添加参数 ->Node --> https://plugins.jenkins.io/nodelabelparameter/ docker pull jenkins/ssh-slave 把php 搞到 agent agent1 还要上 apk add git phing 和 相关dns root运行哦
测试一下 Delegating the first job to agent1
Go to your jenkins dashboard; Select New Item on side menu; Enter a name. (e.g.: First Job to Agent1) Select the Freestyle project and press OK; #我暂时没这个选项 why Check the option: Restrict where this project can be run; Fill the field: label with the agent1 label; (e.g.: agent1)
agent jar形式运行
系统配置： 新建节点： 如果报“从节点端口被禁用”点击“配置连接”或 系统管理->全局安全配置 然后根据页面提示到slave节点进行如下操作： 下载agent： wget https://jenkins.chexiangsit.com/jnlpJars/agent.jar 运行agent： nohup java -jar agent.jar -jnlpUrl http://10.32.221.8:8080/computer/node1/slave-agent.jnlp -secret 8410d288284123c57bff988f693f64dc0d388e5fcefcebef8675196f288c947e -workDir "/opt/jenkins" &
