jenkins - 无法在 groovy 和 jenkins 中解析 json 文件

问题描述

我无法获得图像的名称。我需要 sha256 的值来比较图像。我想将备份的 sha256 与最新的 sha256 进行比较

詹金斯和openshift dsl

代码 ：

def image_list = sh(script:  '  oc get is/account -o json  ', returnStdout: true).trim() as String
println image_list
JsonSlurper slurper = new JsonSlurper()
Map parsedJson = slurper.parseText(image_list)
String idValue = parsedJson.apiVersion
print idValue     ?????

我如何打印最新图像的值和备份图像的值。我想比较 256 张图片

标签： jenkinsgroovy

解决方案

您可以像这样打印它们：

parsedJson.spec.tags.each { tag -> 
    if (tag.name == "latest" || tag.name == "backup") {
        println tag.from.name
    }
}
