** 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 '^(${VARS})' >> /etc/environment"
* config on web
Setup up the agent1 on jenkins.
Go to your Jenkins dashboard;
Go to Manage Jenkins option in main menu;
Go to Manage Nodes and clouds item;
固定 --
ssh 端口 222
然后启动节点
如果遇到报错【The SSH key for this host is not currently trusted. Connections
will be denied until this new key is authorised.】
直接节点配置里面点trust key
agent01
Trust SSH Host Key
:~/tmp$ 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
