Active Choice Parameter + Read Property from Inventory file

[debjyoti sarkar]

Hi,

I have a declarative pipeline in which I have a file called inventory which I want to parse in Active Choice Plugin. Below is the inventory file.

[qaservers]

qa1
qa2
qa3
qa4

[devservers]
dev1
dev2
dev3

[prodservers]
prod1
prod2

I want to parse this in groovy and dynamically retrieve the values from this file based on the branch name. How do I achieve the below result?

def get_environment_qa() {

    return ["qa1", "qa2"]

}

def get_environment_dev() {

    return ["dev1", "dev2"]

}

def get_environment_prod() {

    return ["prod1", "prod2"]

}

if (BRANCH.startsWith("release")) {
         get_environment_qa()

    } else if (BRANCH.startsWith("develop")) {

    get_environment_dev()

} else if (BRANCH.startsWith("master")) {

    get_environment_prod()

}else {

    return ["Unknown state"]

}

I have tried defining a script for get_environment_dev() as below but it doesn't seem to be working.

def get_environment_dev() {

def inventory = readFile 'inventory'

sh 'awk \'/^\\[devservers/ {x=1; next} /^\\[/ {x=0} x==1 && !/^[\\t ]*$/\' inventory > dev_servers'

def dev_servers = readFile'dev_servers'

return dev_servers

}

I guessed it was a problem because it is a string return and not an array. But then I tried looping through the string and storing it array which is also not working. Any help is appreciated. Thanks in advance
