如何在 groovy 中迭代数组参数

Question

Lets say if we multiple envs like dev1, dev2, dev3, qat1, qat2, stg, prod and I have configured multiselect parameters in Jenkins Pipeline. I have saved the selected parameters in array

env = [ dev1, dev3, qat2] 

How do I iterate these parameters one after one in below function

def DockerPush() {

def artifactory_repo_dev1 = "artifactory.dev1.com"
def artifactory_repo_dev3 = "artifactory.dev3.com"
def artifactory_repo_qat2 = "artifactory.qat2.com"


//Docker Tag
sh "docker tag " + "docker-example" + " " + "artifactory_repo_$env" + ":" + version


//Docker Push to Artifactory
    sh "docker push " + "artifactory_repo_$env" + ":" + "${version}"  
}

So that I will not have any duplication of code. Currently I'm using single select parameter and if else statements for all the selected environments which made my code about 500 lines. I want to minimize the code by using a for loop and iterate the selected parameters one by one.

Don't use local vars for such a task (note, that this can be made to work, like you want, but IMHO it's way to convoluted).

Instead use a map to store the relation between environment key and url.

Eg

def chosenEnv = 'env1'
def envToUrl = [env1: "some.url.for.env1.com"]
def url = envToUrl[chosenEnv]

If your urls correlate directly to the env name, you can even generate the map:

def envToUrl = ["env1"].collectEntries{ [it, "some.url.for.${it}.com"] }
