Hi, in my jenkins-job-builder configurations I would like to have one single place where I specify global defaults, then overwrite values only as needed in the according projects/jobs.
This somewhat works with YAML anchors and aliases (see http://pyyaml.org/wiki/PyYAMLDocumentation#Aliases - thanks to Antoine Musso for pointing me there!), where you can use for example "&repos" for assigning a new variable and then "*repos" for referring to it: ,---- [ simple example ] | - defaults: | name: global | repos: &repos | - 'git://git.example.org/foo' | | # here we use the default repos: | - project: | name: test_job1 | repos: *repos | | # here we do NOT use the default repos: | - project: | name: test_job2 | repos: 'git://git.example.org/bar' | [...] | | # finally we use/refer to the repos variable: | - job-template: | name: '{name}-source' | project-type: matrix | scm: | - git: | url: '{repos}' | [...] `---- This also works for lists containing more than one value ("&distri" and "*distri" here): ,---- [ distri.yaml ] | - project: | name: test_distri | distributions: &distri | - precise | - jessie | jobs: | - '{name}-source' | | - job-template: | name: '{name}-source' | project-type: matrix | axes: | - axis: | type: user-defined | name: distribution | values: *distri `---- The resulting config.xml looks as expected: ,---- [ config.xml as resulting from distri.yaml ] | <axes> | <hudson.matrix.TextAxis> | <name>distribution</name> | <values> | <string>precise</string> | <string>jessie</string> | </values> `---- But: I don't want to use the same distributions in all the jobs. Sadly the approach from my simple example above doesn't work here, because I need to pass the distribution list as-is down to the job-template (it's no longer a simple string as for '{repos}' from the example above). Sadly re-using the same anchors/aliases names isn't possible ("yaml.composer.ComposerError: found duplicate anchor ..."), otherwise the solution would be as simple as: ,---- [ fail.yaml ] | - project: | name: custom1 | distributions: &a | - precise | - jessie | jobs: | - '{name}-source' | | - project: | name: custom2 | distributions: &a | - bla | - baz | jobs: | - '{name}-source' | | - job-template: | name: '{name}-source' | project-type: matrix | axes: | - axis: | type: user-defined | name: distribution | values: *a `---- So I need another way how to pass a *list* as data structure from the defaults/project down to the job-template definition, similar to what can be done with "{variable}" for strings. Something like that would come close to what I would need: ,---- [ custom_distri.yaml ] | - project: | name: test_custom_distri | distributions: !!python/tuple [precise, jessie] | jobs: | - '{name}-source' | | - job-template: | name: '{name}-source' | project-type: matrix | axes: | - axis: | type: user-defined | name: distribution | values: '{distributions}' `---- But this does NOT generate what I actually want: ,---- [ config.xml as resulting from custom_distri.yaml ] | <axes> | <hudson.matrix.TextAxis> | <name>distribution</name> | <values> | <string>(</string> | <string>'</string> | <string>p</string> | <string>r</string> | [...] `---- So the "distributions" variable isn't passed as-is. :( I've put my YAML test files online so you can run them through "jenkins-jobs test -o $outputdir $file.yaml" on your own: custom_distri.yaml: https://gist.github.com/mika/8fab6a390cfb96aaf952 distri.yaml: https://gist.github.com/mika/85047c872251abfc4846 fail.yaml: https://gist.github.com/mika/54bc7eaceddce1823332 I've also put a more complete example (including notes of what I already tried to pass the list as-is) online: https://gist.github.com/mika/855dfc96d2e4bd44c10c Any ideas how to properly pass a list of values down to the job-template? regards, -mika-
