Bamboo variables in yaml file (not bamboo specs yaml)

[Erik Zilinsky]

Hello guys! I would like to call a python script  via bamboo task (inline script) This python script load variables from yaml file like this:

parser.add_argument( '--config_path', default='config.yaml', help='path of the configuration file')

with open(args.config_path) as source: 
config = yaml.safe_load(source)

git_config = config['git'] 
git_username = git_config['username'] 
git_password = git_config['password']

In yaml file I would like to use  bamboo variables, how should I define bamboo variables inside yaml file?

Thanks for yout answer!

Hello @Erik Zilinsky welcome to the community! :)

Bamboo provides variables for external scritps with environment variables. While it's possible to hack around your yaml and python scripts (see this StackOverflow answer), I would not recommend you to do that.

The best way to go would be to either read the environment variables direct into your python script, or use the inline variables that Bamboo provides with inline script tasks (documentation link).

I hope that helps!

Thanks for your answer, we want to keep using that yaml file so ... we replacing bamboo vars via chevron python package like this:

import os
import re
import sys
import chevron

template = open(sys.argv[1])

vars = {
'confluence_url': os.environ['bamboo_confluence_url'],
'nexus_user': os.environ['bamboo_nexus_user'],
'nexus_password': os.environ['bamboo_nexus_password'],
'confluence_report_page_id': os.environ['bamboo_confluence_report_page_id'],
'sonar_url' : os.environ['bamboo_sonar_url'],
'sonar_projectkey': os.environ['bamboo_sonar_projectkey'],
'sonar_secret': os.environ['bamboo_sonar_secret']
}

rendered = chevron.render(template, vars)

with open('config_composed.yaml', 'w') as composed:
print(rendered, file=composed)

Have a nice day!
