Generate job matrix from all possible combinations of input parameters

问题

I would like to generate jobs in Azure Pipelines using the matrix strategy, but not by explicitly listing all possible combinations. Instead of doing:

matrix:
  core211:
    module: core
    scala: 2.11
  python211:
    module: python
    scala: 2.11
  libraries211:
    module: ibraries
    scala: 2.11
  core212:
    module: core
    scala: 2.12
  python212:
    module: python
    scala: 2.12
  libraries212:
    module: libraries
    scala: 2.12

I want to do

matrix:
  combinations:
    module: ["libraries", "python", "core"]
    scala: ["2.11", "2.12"]

to generate above matrix. Is this possible with Azure Pipelines?

I got this approach from Travis CI.

回答1:

I'm afraid the answer is negative. For now, it's not a supported scenario.

About the Matrix schema in yaml please check this document:

strategy:
  matrix: { string1: { string2: string3 } }
  maxParallel: number

It equals to:

    matrix:
      string1:
        string2: string3
        .
        .
        .
      string1:
        string2: string3
        .
        .
        .

According to the docs: For each string1 in the matrix, a copy of the job will be generated. string1 is the copy's name and will be appended to the name of the job.

So if we want to generate 6 jobs, for now we have to list 6 "string1". (It means we do need to explicitly list all possible combinations...)

In addition:

Apart from the negative answer, I think what you want is a good idea! So I post a feature request here in DC forum. Anyone interested in this can vote for it and track it. Hope all above makes some help :)
