HI
i am trying use for loop, however its not working.

Loop over each key in mandatory_keys

for key in mandatory_keys {

Check if key is present in new_labels_keys

if not key in new_labels_keys {
all_keys_present = false
}
}
}

label_pattern_match {

pattern = "^[a-z0-9]+$"
all_match := [regex.match(new_labels[key], pattern) | key := object.keys(new_labels)]
all_match_result = all_match[_]
all_match_result
}

values := {value | value := new_labels[_]}

Hi there 👋 There is no "for" construct in Rego. You can use some .. in for iteration, or coll[_], etc... but in your example it looked like you wanted to check for every. I think this would do what you wanted: https://play.openpolicyagent.org/p/Yggru6R2zR

Hi All,

I was trying to print the missing labels in sprintf section (i.e if any label is missing from mandatory_labels if should print the missing label)
and the same is with the pattern (i.e if patten is missing with any label values it should print the value for that)

i updated the code accordingly, however, i am not getting the desired result, can you please have a look?
rego playground - https://play.openpolicyagent.org/p/BwZx4k25l8

the error i am getting
1 error occurred: policy.rego:12: rego_parse_error: unexpected ; token: expected "," or "]"
msg := sprintf("Mandatory labels %v are missing", [key, _ in mandatory_labels; key not in new_labels_keys])

Hi @backbencherengineer, I'm about to head out for the day but this might work for you: https://play.openpolicyagent.org/p/73isQqPRB3
