如何使用CLI使Jenkins主节点脱机？ [英] How to take Jenkins master node offline using CLI?

问题描述

当我同步我们的开发数据库时，我已经手动将主节点（而且只有）节点离线，以避免一系列错误的测试失败。我有一个脚本，做完整的数据库导入，并希望自动化的节点维护。

I have been manually taking the master (and only) node offline whenever I sync our development database to avoid a bunch of false test failures. I have a script that does the full DB import and would like to automate the node maintenance as well.

如何标记主节点暂时离线使用命令行接口JAR？

How can I mark the master node temporarily offline using the command-line interface JAR?

• 我写了一个简单的Bash脚本来执行Jenkins任务。



• 我可以使用该脚本进行身份验证。

• I wrote a simple Bash script to execute Jenkins tasks.

• I can authenticate using that script.

$ jenkins who-am-i
Authenticated as: david
Authorities:
  david
  authenticated

code> offline-node 或 online-node 来识别主节点。帮助说明我可以省略master的节点名，但这不起作用。

However, I cannot get offline-node or online-node to recognize the master node. The help states that I can omit the node name for "master", but that doesn't work.

$ jenkins offline-node
Argument "NAME" is required
java -jar jenkins-cli.jar online-node NAME
Stop using a node for performing builds temporarily, until the next "online-node" command.
 NAME                : Slave name, or empty string for master

一个奴隶，但我需要把主人的执行者离线。

It seems to be looking specifically for a slave, but I need to take the master's executor offline.

$ jenkins offline-node master
No such slave "master" exists. Did you mean "null"?

推荐答案

如果你只有一个构建执行器在主机和没有独立的构建节点，使用这个命令代替：

If you only have one build executor on the master and no standalone build nodes, use this command instead:

java -jar jenkins-cli.jar quiet-down

这将停止任何新构建的执行。您可以使用

This will stop any new builds from executing. You can use

java -jar jenkins-cli.jar cancel-quiet-down

使Jenkins重新上线;此时它将运行在离线时排队的任何版本。

to put Jenkins back on line; at this point it will run any builds that were queued up while it was offline.
