I’m using ec2.py dynamic inventory successfully with limiting by _multiple tags_, but my need is to be able to limit by a tag where _one_ of the compound values matches, but I haven’t found a way to do so yet.

Example: Tag = Apps Compound value = app1|app2|app3|app4

I’m kicking this off via Jenkins, using the Invoke Ansible Playbook build step, where I’m passing -i ec2.py under “Additional parameters” and passing the limit under the “Host subset” section. The “Host subset” tags are built with variables passed in:

tag\_Apps\_${appname},tag\_Location\_${location}

I’m passing in one of the compound values as appname. Is there a way to do a limit with a tag where **at least one** of the compound values matches? Obviously the way I’m building the tag now and passing it in doesn’t work since it looks for that exact tag - just showing a working example of what works for a tag with a single value.
