** 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

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 '^(${VARS})' >> /etc/environment"
* config on web
Setup up the agent1 on jenkins.
1. Go to your Jenkins dashboard;
2. Go to Manage Jenkins option in main menu;
3.Go to Manage Nodes and clouds item;
4.Go to New Node option in side menu;
5.Fill the Node/agent name and select the type; (e.g. Name: agent1, Type: Permanent Agent)
6.Now fill the fields:
Remote root directory; (e.g.: /home/jenkins )
label; (e.g.: agent1 )
usage; (e.g.: only build jobs with label expression…)
Launch method; (e.g.: Launch agents by SSH )
Host; (e.g.: localhost or your IP address )
Credentials; (e.g.: jenkins )
Host Key verification Strategy; (e.g.: Manually trusted key verification … )
自己要注意的细节 因为母机的22不能再用了
固定 --
ssh 端口 222
Now press the button Launch agent and wait some seconds, then you should receive
the message: Agent successfully connected and online on the last log line.
Agent successfully connected
然后启动节点
如果遇到报错【The SSH key for this host is not currently trusted. Connections
will be denied until this new key is authorised.】
直接节点配置里面点trust key
agent1
Trust SSH Host Key
:~/tmp$ 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
