Molecule: Support --skip-tags in addition to --tags

[tknerr]

Sometimes it's handy to run molecule converge --tags "foo" to converge only the roles / tasks with the given tag.

But now lets assume that a role tagged with "foo" depends on another role "heavystuff". In this case, running molecule converge --tags "foo" also implies running "heavystuff" due to the role dependencies (which is good actually :)).

So if you don't want to run "heavystuff" but only "foo", you would have to pass --tags "foo" --skip-tags "heavystuff" to ansible.

Molecule currently only provides passing --tags, so additionally passing --skip-tags as well would be nice.

Btw I aslo tried --tags "foo,!heavystuff" but this seems to be not supported by ansible

@tknerr is this workflow something you want to occur every time you run molecule? Each time you converge you wish to skip tags for a particular role your developing?

[tknerr]

@retr0h nope this was more like a one-off use case where I was making changes in "foo" and didn't want to run all the "heavystuff" too... just to iterate a bit more quickly during development

[tknerr]

Wow, that was fast. Thanks @retr0h !

This feature was released with molecule 1.13 which is live on pypi.

Dear all,

just for understanding - this patch only applies to molecule converge and not molecule test - would it be possible to add for latter too?

I'm not sure if I misunderstood but this does not seem to work for me:

(ona) user@user-ThinkPad-T580:~/work/playbooks/roles/zebra$ molecule converge --tags "test-logrotate"
Usage: molecule converge [OPTIONS] [ANSIBLE_ARGS]...
Try 'molecule converge --help' for help.

Error: no such option: --tags
(ona) user@user-ThinkPad-T580:~/work/playbooks/roles/zebra$ molecule --version
molecule 3.0.3
   ansible==2.8.0 python==3.6

[FrankApiyo]

huh! ok... seems what I needed to do was molecule converge -- --tags "test-logrotate"
