Build the name of Bamboo variable in script

Question

Is it possible to concatenate a string to call a Bamboo variable.

Using a script task in Bamboo, I want to generalize the following:

python my.py moon ${bamboo.mynamespace.moon}

to

SET planet=MOON
python my.py %planet% ${bamboo.mynamespace.%planet%}

But doing it like the second example above results in my python script receiving

${bamboo.mynamespace.%planet%}

as a string and not the value of

${bamboo.mynamespace.moon}

I know... moon is not a planet

I don't think it's going to be possible in the way how you're using it. Because once you use ${bamboo.variableName} Bamboo tries to resolve the variable and substitute it with a variable value. Since there's no variable%planet% Bamboo can't reference it.

But I think you could reorganise your solution a bit and make use environment variables (all Bamboo variables are passed to process as environment variables). So e.g. if Bamboo variable's name is variable.name you're allowed to reference to it via ${bamboo_variable_name} (bamboo prefix + all dots are replaced with underscore)

Then I can imagine you could get variable which interests you via print os.environ['bamboo_mynamespace_' + 'planet'] (more info on env variables in python here)

Aha.. Clever. I'll try it – niCk cAMel Sep 26 '17 at 06:34
Excellent, it works. Cant get how I missed that, since the bamboo log prints out all variables it injects to OS ENV. *BUT* the underscore instead of dots isn't obvious at all! Thanks. – niCk cAMel Sep 26 '17 at 06:42
"bamboo log prints out all variables it injects to OS ENV" ? No it doesn't. hehe... – niCk cAMel Sep 26 '17 at 07:23
