jenkins 節點配置使用小記

jenkins節點容器有兩種，一種是ssh-slave，master使用ssh命令連線節點，另一種是jnlp-slave，節點通過url連線master，以下使用的的是ssl-slave

• jnlp-slave 使用相關

• ssh-slave 使用相關
  https://github.com/jenkinsci/docker-ssh-sl...
• 拉取 ssh-slave 倉庫程式碼
  https://github.com/jenkinsci/docker-ssh-sl...
• 二開 Dockerfile 檔案

- 構建映象 docker-compose up -d --build，查詢容器的IP
- 系統管理->節點管理，新增節點，host為slave容器的IP
