How to Join 2 variables in YAML
variables:
- name: Table
value: 'table'
- name: Tennis
value: 'tennis'
- name: Combine
value: variables.Tennis + ' is '+ variables.Table
The expected output is "table is tennis"
I tried concatenating 2 variables or 2 parameters into a variable and it's not working out with + please suggest
- name: commonCommand
value: ${{ format(' {0} is {1} ', variables.Table, variables.Tennis)}}

Using yq (v4.25.3), and considering the following yaml file
accounts:
- account_id: 'XXXXXXXX'
name: sandbox
deploy_iam: true
role: arn:aws:iam::XXXXXXXX:role/iam_role
regions:
- all
- account_id: 'YYYYYYY'
name: dev
deploy_iam: true
role: arn:aws:iam::YYYYYYY:role/iam_role
regions:
- all
Is it possible to get the value of the deploy_iam attribute given an account_id value?
I can get the list of account_id with
yq '.accounts[].account_id' < accounts.yml
And I tried to filter using with_entries
yq '.accounts[].account_id |= with_entries(select(.key == "XXXXXXXX"))' < accounts.yml
Without luck so far.
Any idea?
With mikfarah/yq it should be pretty straightforward. Select the required object with the select() expression and access the required field with the dot notation
yq '.accounts[] | select(.account_id == "XXXXXXXX").deploy_iam' < accounts.yml
I'm trying to add a map to an array of maps in ytt to modify a YAML doc.
I tried the below but it errors out and says it expects a map but getting an array.

You were really close in your solution, all you really needed was to make reviewers an array item. If you want to be able to add reviewers to a book that does not have that key, then you will have to add a matcher on the array item and the map item; a gist is included below to see this behavior overlay in action.
If you have more than one ##overlay/match annotation on the same item, the last one wins. There are plans to improve this behavior: https://github.com/k14s/ytt/issues/114.

I have a dictionary of dictionaries collecting data from openshift using prometheus. Now I intend to add values in all the dictionaries. But some projects don't have quota and hence some pods don't have request/limit set for cpu and memory. I am trying the following and it fails in case the key:value is not there.
If possible I want to use if else such that, if the variable exists then add the variable else use the value as 0.
- name: Total section for Projects
set_fact:
pod_count_total: "{{ (pod_count_total|int) + (item.value.pod_count|int)}}"
total_cpu_request: "{{ (total_cpu_request|float |round(2,'ceil')) + (item.value.cpu_request|float |round(2,'ceil'))}}"
total_cpu_limit: "{{ (total_cpu_limit|float |round(2,'ceil')) + (item.value.cpu_limit|float |round(2,'ceil'))}}"
total_memory_request: "{{ (total_memory_request|float |round(2,'ceil')) + (item.value.memory_request|float |round(2,'ceil'))}}"
total_memory_limit: "{{ (total_memory_limit|float |round(2,'ceil')) + (item.value.memory_limit|float |round(2,'ceil'))}}"
with_dict: "{{all_project}}"
Dictionary of dictionaries is like
ok: [127.0.0.1] => {
"msg": {
"openshift-web-console": {
"cpu_usage": 0.015,
"memory_used": 0.04,
"cpu_request": 0.301,
"memory_request": 0.293,
"pod_count": 3
},
"srv-test": {
"cpu_usage": 0.013,
"memory_used": 0.02,
"pod_count": 5
},
"test": {
"cpu_usage": 0.001,
"memory_used": 0.0,
"pod_count": 1
},
"openshift-monitoring": {
"cpu_limit": 1.026,
"cpu_request": 0.556,
"cpu_usage": 0.786,
"memory_limit": 1.866,
"memory_request": 1.641,
"memory_used": 0.14,
"pod_count": 98
}
}
}
If possible I want to use if else such that, if the variable exists then add the variable else use the value as 0.
The thing you are looking for is the default filter
total_memory_request: "{{ (
total_memory_request | default(0)
| float | round(2,'ceil')
) + (
item.value.memory_request | default(0)
| float | round(2,'ceil')
) }}"
There's a subtlety in that if the variable exists but is the empty string, you'll need to pass in the 2nd parameter to default to have it act in a python "truthiness" way: {{ "" | default(0, true) | float }} -- that might not apply to you, but if it does, you'll be glad to know what that 2nd param does

I am trying to create a GitBook page with a list of items containing no duplicates. I.e I would want to apply a 'unique' filter or 'distinct' filter in my Nunjucks template for the page. The template needs to process the page variables (YAML). The above template generates the output:
Countries: DE,US,DE,US
I would like it to produce the output
Countries: DE,US
How could I achive that? (Given that 'unique' filter is not supported with Nunjucks.)
You can extend your Nunjucks through Custom filter
const nunjucks = require('nunjucks');
const env = new nunjucks.Environment(/* loaders etc... */);
env.addFilter('unique', arr => arr instanceof Array && arr.filter((e, i, arr) => arr.indexOf(e) == i) || arr);
let out = env.renderString(`{{[1, 2, 3, 2] | unique }}`);
console.log(out);
I am writing a Ruby gem that converts a sql executable to yaml, using Yaml::dump. However, when testing it in Postgresql I am finding that the integers are output with single quotes around them (as strings) unless they start with a zero. Below is the code snippet of the call to Yaml::dump and some resulting data.
db_object = {}
db_output = {}
full_table = ActiveRecord::Base.connection.execute("SELECT * FROM #{model};")
keys = full_table[0].keys
db_object["columns"] = keys
model_arr=[]
full_table.each do |row|
model_arr << row.values_at(*keys)
end
db_object["records"] = model_arr
db_output[model] = db_object
YAML::dump(db_output, file)
And here are the first couple rows of results:
schema_migrations:
columns:
- version
records:
- - '20121225230020'
- - '20121225230129'
---
students:
columns:
- id
- first_name
- last_name
- date_of_birth
- rank
- phone
records:
- - '1'
- Celestino
- Towne
- '2007-09-20'
- '2'
- '6417358360'
Any insight would be much appreciated.
