Evaluate the multiplier field variable of the environment

Question

I try Something like in vsts release management:

• Define variable a with : 1,2,3
• Define variable b with : 4,5,6
• Define variable c with : $(a),$(b)
• Use variable c in field Multiplier when i use environment Multi-configuration parallelism capability.

Result : 2 times environments deployed : $(a) and $(b) I want deploy 6 times the envoironment : 1,2,3,4,5 and 6

An Idea to workaround ?

In a build task the variable $(c) is expanded and value is : 1,2,3,4,5,6 ... I don't uderstand why field "Multiplier" not expand the variable

Answer 1

You should use variables a and b separate by comma (a,b) for Multipliers option.

Only the variables you specifies in Multipliers option, the variables values will be act as a multiplier. So if you use a,b for Multipliers option, values from variable a and variable b will be multiplied as 1,4, 1,5, 1,6, 2,4, 2,5, 2,6, 3,4, 3,5 and 3,6 (deploy 9 times).

If you use only one variable c for Multipliers option, vsts only deploy the values (separate by comma) from variable c separately. So as you found, it only deploy two times as $(a) and $(b).

More details, you can also find the examples in Parallel and multiple execution using agent phases.
