如何在Jenkins可锁定资源插件中获取锁定资源的名称
如何在Jenkins可锁定资源插件中获取锁定资源的名称
提问于 2020-04-09 14:19:14
我正在使用Jenkins Lockable Resources插件来决定在我的声明性管道中使用哪个服务器来进行各种构建操作。我已经设置了我的Lockable Resources，如下表所示：
Resource Name Labels
Win_Res_1 Windows
Win_Res_2 Windows
Win_Res_3 Windows
Lx_Res_1 Linux
Lx_Res_2 Linux
Lx_Res_3 Linux我想锁定一个label，然后获取相应的锁定resource的名称。
我正在编写以下代码，但无法获得所需的r值
int num_resources = 1;
def label = "Windows"; /* I have hardcoded it here for simplicity. In actual code, I will get ${lable} from my code and its value can be either Windows or Linux. */
lock(label: "${label}", quantity: num_resources)
{
def r = org.jenkins.plugins.lockableresources.LockableResourcesManager; /* I know this is incomplete but unable to get correct function call */
println (" Locked resource r is : ${r} \n");
/* r should be name of resource for example Win_Res_1. */
}此处提供了Lockable Resources Plugin的文档：https://jenkins.io/doc/pipeline/steps/lockable-resources/和https://plugins.jenkins.io/lockable-resources/

您可以使用lock工作流步骤的variable参数获取锁定资源的名称。此选项定义将存储锁定资源名称的环境变量的名称。考虑下面的例子。
pipeline {
agent any
stages {
stage("Lock resource") {
steps {
script {
int num = 1
String label = "Windows"
lock(label: label, quantity: num, variable: "resource_name") {
echo "Locked resource name is ${env.resource_name}"
}
}
}
}
}
}在本例中，可以使用env.resource_name变量访问锁定的资源名称。以下是管道运行的输出。
[Pipeline] {
[Pipeline] stage
[Pipeline] { (Lock resource)
[Pipeline] script
[Pipeline] {
[Pipeline] lock
Trying to acquire lock on [Label: Windows, Quantity: 1]
Lock acquired on [Label: Windows, Quantity: 1]
[Pipeline] {
[Pipeline] echo
Locked resource name is Win_Res_1
[Pipeline] }
Lock released on resource [Label: Windows, Quantity: 1]
[Pipeline] // lock
[Pipeline] }
[Pipeline] // script
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS您可以看到，env.resource_name变量被赋值为Win_Res_1。
