Re: Declarative Pipeline v1.4.0-beta-1 - Matrix stages
Thanks very much Liam,
I will immediately try and demo this in my organization for multiple
multi-platform (pun intended) use cases!
This is why I love jenkins plugins API ecosystem, it is by far the deepest
and most feature rich in the CI landscape and promotes immense code reuse.
Sincerely
Firmsoil

This is fantastic to see land - I've been dreaming of matrix in Declarative
for years, so thank you, Liam, for making it happen!

This seems like a lot of conceptual weight for something that could
have been expressed in Scripted with a simple `if`-statement or two.
Is there some guiding principle for how much logic ought to be
expressible in Declarative?

Declarative Pipeline v1.4.0-beta-1 - Matrix stages
Hello all!
I'm pleased to announce the release of Declarative Pipeline 1.4.0-beta-1
with Matrix Stages. This feature allows pipeline authors to specify a
matrix of one or more dimensions and run a set of stages on the combination
of values specified.
One simple use case where Matrix Stages are valuable is running browser
tests on several operating systems and browser combinations. Let’s say we
want to run tests on Linux, OS X, and Windows for browsers Chrome, Firefox,
IE, and Safari. We’ll want to run tests for IE on Windows only and we’ll
want tests for Safari to run on OS X and Windows. Here’s what that
scenario will look like using the new “matrix” directive:
Jenkinsfile
--
pipeline {
agent none
stages {
stage("foo") {
matrix {
axes {
axis {
name 'os'
values "linux", "windows", "mac"
}
axis {
name 'browser'
values "firefox", "chrome", "safari", "ie"
}
}
excludes {
exclude {
axis {
name 'os'
values 'linux'
}
axis {
name 'browser'
values 'safari'
}
}
exclude {
axis {
name 'os'
notValues 'windows'
}
axis {
name 'browser'
values 'ie'
}
}
}
stages {
stage("first") {
steps {
echo "Running on OS=$os, BROWSER=$browser"
}
}
stage("second") {
steps {
// ... Second stage steps ...
}
}
}
}
}
}
}
--
In the example, we specify two axes and the values for each of them. Then,
we use the optional “excludes” directive to remove undesired combinations
from the matrix. Finally, we specify one or more stages that we want to run
on each combination.
Log fragment:
…
[Pipeline] stage
[Pipeline] { (foo)
[Pipeline] parallel
[Pipeline] { (Branch: Matrix: os = 'linux', browser = 'firefox')
[Pipeline] { (Branch: Matrix: os = 'windows', browser = 'firefox')
[Pipeline] { (Branch: Matrix: os = 'mac', browser = 'firefox')
[Pipeline] { (Branch: Matrix: os = 'linux', browser = 'chrome')
[Pipeline] { (Branch: Matrix: os = 'windows', browser = 'chrome')
[Pipeline] { (Branch: Matrix: os = 'mac', browser = 'chrome')
[Pipeline] { (Branch: Matrix: os = 'windows', browser = 'safari')
[Pipeline] { (Branch: Matrix: os = 'mac', browser = 'safari')
[Pipeline] { (Branch: Matrix: os = 'windows', browser = 'ie')
...
Declarative Pipeline 1.4.0-beta-1 is available from the experimental update
center now (
https://jenkins.io/doc/developer/publishing/releasing-experimental-updates/).
I look forward to hearing what you think of this feature and what you’d
like to see in future updates to Declarative Pipeline.
Thanks,
Liam Newman
