在部署场景中,我需要在主机列表上创建和运行jenkins任务,即创建类似参数化任务(其中ip地址是参数)或具有HOST轴的Multijob Plugin上的任务,但仅运行在多个主机上并行2个。
其中一个选项可能是使用主机列表运行ansible,但我希望分别查看每个主机的状态,并在需要时重新启动jenkins作业。
主要选项是使用Job DSL Plugin或Pipeline Plugin,但在这里我需要帮助来理解应该使用dsl groovy代码的类/方法来实现这一点。
任何人都可以帮忙吗?

假设主机已经配置为Jenkins从属设备。
假设在管道作业参数中提供了主机
HOSTS
作为空格分隔列表。以下示例应该让您入门:
def hosts_pairs = HOSTS.split().collate(2)
for (pair in host_pairs) {
def branches = [:]
for (h in pair) {
def host = h // fresh variable per iteration; it will be mutated
branches[host] = {
stage(host) {
node(host) {
// do the actual job here, e.g.
// execute a shell script
sh "echo hello world"
}
}
}
}
parallel branches
}

Matrix project和Throttle Concurrent Builds Plugin的组合是可能的。
您只需要设置一个用户定义的轴(例如" targetHost"),并将所有IP地址作为值,并在" Throttle Concurrent Builds"下设置所需的限制。 (请注意,必须启用"执行并发构建,如果需要"选项告诉jenkins允许并发执行)。
在相应的环境变量(例如targetHost
)中的每个子构建期间,轴值都可用。
下面是一个示例config.xml,其中包含简单的ping& wait构建步骤:
